# Version 8.6.0 Changes
## [New Mermaid Live-Editor Beta](https://mermaid-js.github.io/docs/mermaid-live-editor-beta/#/edit/eyJjb2RlIjoiJSV7aW5pdDoge1widGhlbWVcIjogXCJmb3Jlc3RcIiwgXCJsb2dMZXZlbFwiOiAxIH19JSVcbmdyYXBoIFREXG4gIEFbQ2hyaXN0bWFzXSAtLT58R2V0IG1vbmV5fCBCKEdvIHNob3BwaW5nKVxuICBCIC0tPiBDe0xldCBtZSB0aGlua31cbiAgQyAtLT58T25lfCBEW0xhcHRvcF1cbiAgQyAtLT58VHdvfCBFW2lQaG9uZV1cbiAgQyAtLT58VGhyZWV8IEZbZmE6ZmEtY2FyIENhcl1cblx0XHQiLCJtZXJtYWlkIjp7InRoZW1lIjoiZGFyayJ9fQ)
## [CDN](https://unpkg.com/mermaid/)
With version 8.6.0 comes the release of directives for mermaid, a new system for modifying configurations, with the aim of establishing centralized, sane defaults and simple implementation.
`directives` allow for a single-use overwriting of `config`, as it has been discussed in [Configurations](./Setup.md).
This allows site Diagram Authors to instantiate temporary modifications to `config` through the use of [Directives](), which are parsed before rendering diagram definitions. This allows the Diagram Authors to alter the appearance of the diagrams.
**A likely application for this is in the creation of diagrams/charts inside company/organizational webpages, that rely on mermaid for diagram and chart rendering.**
the `init` directive is the main method of configuration for Site and Current Levels.
The three levels of are Configuration, Global, Site and Current.
| Level of Configuration | Description |
| --- | --- |
| Global Configuration| Default Mermaid Configurations|
| Site Configuration| Configurations made by site owner|
| Current Configuration| Configurations made by Implementors|
# Limits to Modifying Configurations
**secure Array**
| Parameter | Description |Type | Required | Values|
| --- | --- | --- | --- | --- |
| secure | Array of parameters excluded from init directive| Array | Required | Any parameters|
The modifiable parts of the Configuration are limited by the secure array, which is an array of immutable parameters, this array can be expanded by site owners.
**Notes**: secure arrays work like nesting dolls, with the Global Configurations secure array being the default and immutable list of immutable parameters, or the smallest doll, to which site owners may add to, but implementors may not modify it.
# Secure Arrays
Site owners can add to the **secure** array using this command:
mermaidAPI.initialize( { startOnLoad: true, secure: ['parameter1', 'parameter2'] } );
default values for the `secure array` consists of: ['secure', 'securityLevel', 'startOnLoad', 'maxTextSize']. These default values are immutable.
Implementors can only modify configurations using directives, but cannot change the `secure` array.
# Modifying Configurations and directives:
The Two types of directives: are `init` or `initialize` and `wrap`.
```note
All directives are enclosed in `%%{ }%%`
```
Older versions of mermaid will not parse directives because `%%` will comment out the directive. This makes the update backward compatible.
# Init
`init`, or `initialize`: the init or initialize directive gives the user the ability to overwrite and change the values for configuration parameters, with respect to the secure array that is in effect.
| Parameter | Description |Type | Required | Values|
| --- | --- | --- | --- | --- |
| init | modifies configurations| Directive| Optional | Any parameters not included in the secure array|
```note
init would be an argument-directive: `%%{init: { **insert argument here**}}%%`
The json object that is passed as {**argument** } must be valid, quoted json or it will be ignored.
**for example**:
`%%{init: {"theme": default, "logLevel": 1 }}%%`
Configurations that are passed through init cannot change the parameters in secure arrays of higher levels. In the event of a conflict, mermaid will give priority to secure arrays and parse the request, without changing the values of the parameters in conflict.
When deployed within code, init is called before the graph/diagram description.
```
**for example**:
```mmd
%%{init: {"theme": "default", "logLevel": 1 }}%%
graph LR
a-->b
b-->c
c-->d
d-->e
e-->f
f-->g
g-->
```
# Wrap
| Parameter | Description |Type | Required | Values|
| --- | --- | --- | --- | --- |
| wrap | a callable text-wrap function| Directive| Optional | %%{wrap}%%|
```note
Wrap is a function that is currently only deployable for sequence diagrams.
wrap respects manually added <br\> so if the user wants to break up their text, they have full control over those breaks by adding their own <br\> tags.
It is a non-argument directive and can be executed thusly:
`%%{wrap}%%` .
```
**an example of text wrapping in a sequence diagram**:
![Image showing wrapped text](img/wrapped%20text.png)
# Resetting Configurations:
There are two more functions in the mermaidAPI that can be called by site owners: **reset** and **globalReset**.
**reset**: resets the configuration to whatever the last configuration was. This can be done to undo more recent changes to the last mermaidAPI.initialize({...}) configuration.
**globalReset** will reset both the current configuration AND the site configuration back to the global defaults.
**Notes**: both reset and globalReset are only available to site owners, as such implementors would have to edit their configs with init.
# Additional Utils to mermaid
**memoize**: simple caching for computationally expensive functions. It reduces the rendering time for computationally intensive diagrams by about 90%.
**assignWithDepth** - this is an improvement on previous functions with config.js and Object.assign. The purpose of this function is to provide a sane mechanism for merging objects, similar to object.assign, but with depth.
Example of **assignWithDepth**:
![Image showing assignWithDepth](img/assignWithDepth.png)
Example of **object.Assign**:
![Image showing object.assign without depth](img/object.assign%20without%20depth.png)
**calculateTextDimensions, calculateTextWidth,** and **calculateTextHeight** - for measuring text dimensions, width and height.
**Notes**:For more information on usage, parameters, and return info for these new functions take a look at the jsdocs for them in the utils package.

# Change Log
Here is the list of the newest versions in Descending Order, beginning from the latest version.
## Unreleased
[Full Changelog](https://github.com/knsv/mermaid/compare/8.7.0...HEAD)
## 8.7.0 (2020-08-09)
🔖 [Release Notes](https://github.com/mermaid-js/mermaid/releases/tag/8.7.0) |
📜 [Full Changelog](https://github.com/mermaid-js/mermaid/compare/8.6.0...8.7.0)
This version brings with it a system for [dynamic and integrated configuration of the diagram themes](./theming.md).
The objective of this is to increase the customizability of mermaid and the ease of Styling, with the customization of themes through the `%%init%%` directive and `initialize` calls.
Themes follow and build upon the Levels of Configuration and employ `directives` to modify and create custom configurations, as they were introduced in Version [8.6.0](../getting-started/8.6.0_docs.md).
**These Theming Configurations, similar to directives, will also be made applicable in the Live-Editor, for easier styling.**
### Site-wide Themes
Site-wide themes are still declared via `initialize` by site owners.
Example of `Initalize` call setting `theme` to `base`:
```javascript
mermaidAPI.initialize({
'securityLevel': 'loose', 'theme': 'base'
});
```
**Notes**: Only site owners can use the `mermaidAPI.initialize` call, to set values. Site-Users will have to use `%%init%%` to modify or create the theme for their diagrams.
### Themes at the Local or Current Level
When Generating a diagram using on a webpage that supports mermaid.
It is also possible to override site-wide theme settings locally, for a specific diagram, using directives, as long as it is not prohibited by the `secure` array.
**Following is an example:**
```mmd
%%{init: {'theme':'base'}}%%
graph TD
a --> b
```
### Making a Custom Theme with `themeVariables`
The easiest way to make a custom theme is to start with the base theme, and just modify theme variables through `themeVariables`, via `%%init%%`.
| Parameter | Description | Type | Required | Objects contained |
| -------------- | ------------------------------------------------------------------ | ----- | -------- | ---------------------------------- |
| themeVariables | Array containing objects, modifiable with the `%%init%%` directive | Array | Required | primaryColor, lineColor, textColor |
Here is an example of overriding `primaryColor` and giving everything a different look, using `%%init%%`.
```mmd
%%{init: {'theme': 'base', 'themeVariables': { 'primaryColor': '#ff0000'}}}%%
graph TD
A[Christmas] -->|Get money| B(Go shopping)
B --> C{Let me think}
B --> G[/Another/]
C ==>|One| D[Laptop]
C -->|Two| E[iPhone]
C -->|Three| F[fa:fa-car Car]
subgraph section
C
D
E
F
G
end
```
**Notes:**
Leaving it empty will set all variable values to default.
## 8.6.0 (2020-07-13)
🔖 [Release Notes](https://github.com/mermaid-js/mermaid/releases/tag/8.6.0)
[Version 8.6.0](../getting-started/8.6.0_docs.md) introduces New Configuration Protocols and Directives and a Beta for the [New Mermaid Live-Editor](https://mermaid-js.github.io/docs/mermaid-live-editor-beta/#/edit/eyJjb2RlIjoiJSV7aW5pdDoge1widGhlbWVcIjogXCJmb3Jlc3RcIiwgXCJsb2dMZXZlbFwiOiAxIH19JSVcbmdyYXBoIFREXG4gIEFbQ2hyaXN0bWFzXSAtLT58R2V0IG1vbmV5fCBCKEdvIHNob3BwaW5nKVxuICBCIC0tPiBDe0xldCBtZSB0aGlua31cbiAgQyAtLT58T25lfCBEW0xhcHRvcF1cbiAgQyAtLT58VHdvfCBFW2lQaG9uZV1cbiAgQyAtLT58VGhyZWV8IEZbZmE6ZmEtY2FyIENhcl1cblx0XHQiLCJtZXJtYWlkIjp7InRoZW1lIjoiZGFyayJ9fQ)
**With version 8.6.0 comes the release of directives for mermaid, a new system for modifying configurations, with the aim of establishing centralized, sane defaults and simple implementation.**
Directives allow for a diagram specific overriding of config, as it has been discussed in Configurations.
This allows site users to input modifications to config alongside diagram definitions, when creating diagrams on a private webpage that supports Mermaid.
## 8.5.0 (2020-04-11)
🔖 [Release Notes](https://github.com/mermaid-js/mermaid/releases/tag/untagged-31c93788afe260d914bb)
This version introduces New diagrams!
**New diagrams in 8.5**
With version 8.5 there are some bug fixes and enhancements, plus a new diagram type, entity relationship diagrams.
![Image showing the new ER diagram type](./img/er.png)
## 8.2.0 (2019-07-17)
🏷️ [Tag](https://github.com/mermaid-js/mermaid/tree/8.2.0)
Version 8.2.0, introduces a security improvement.
A `securityLevel` configuration has to first be cleared, `securityLevel` sets the level of trust for the parsed diagrams and limits click functionality.
This was introduced in version 8.2 as a security improvement, aimed at preventing malicious use.
### securityLevel
| Parameter | Description | Type | Required | Values |
| ------------- | --------------------------------- | ------ | -------- | ------------------------- |
| securitylevel | Level of trust for parsed diagram | String | Required | Strict, Loose, antiscript |
**Notes:**
- **strict**: (**default**) tags in text are encoded, click functionality is disabled
- **loose**: tags in text are allowed, click functionality is enabled
- **antiscript**: html tags in text are allowed, (only script element is removed), click functionality is enabled
⚠️ **Note**: This changes the default behaviour of mermaid so that after upgrade to 8.2, if the `securityLevel` is not configured, tags in flowcharts are encoded as tags and clicking is prohibited.
If you are taking responsibility for the diagram source security you can set the `securityLevel` to a value of your choosing.
By doing this clicks and tags are again allowed.
### To change `securityLevel` with `mermaidAPI.initialize`:
```javascript
mermaidAPI.initialize({
securityLevel: 'loose'
});
```

# Configuration
Configuration is the second half of Mermaid, after deployment. Together Deployment and Configuration constitute the whole of Mermaid.
This section will introduce the different methods of configuring of the behaviors and appearances of Mermaid Diagrams.
The Following are the most commonly used methods, and are all tied to Mermaid [Deployment](./n00b-gettingStarted.md) methods.
## Configuration Section in the [Live Editor](https://mermaid-js.github.io/mermaid-live-editor).
## The `initialize()` call, for when Mermaid is called via an API, or through a <script> tag.
## [Directives](./directives.md),
allows the limited reconfiguration of a diagram just before it is rendered. It can alter the font style, color and other aesthetic aspects of the diagram. you can pass a directive alongside your definition inside `%%{ }%%`, either above or below your diagram definition.
## Theme Creation:
An application of using Directives to change [Themes](./theming.md). `Theme` is an value within mermaid's configuration that dictates the color scheme for diagrams.
If you are interested in altering and customizing your Mermaid Diagrams, you will find the methods and values available for [Configuration](./Setup.md) here. It includes themes

The main purpose of Mermaid is to help with Visualizing Documentation, and helping it catch up with Development.
> Documentation-Rot is a Catch-22 that Mermaid helps to solve.
Diagramming and Documentation cost precious developer time and get outdated quickly.
However, not having diagrams or documentation ruins productivity and hampers organizational learning.
Mermaid addresses this Catch-22 situation by reducing the time, effort and tooling that is required to create modifiable diagrams and charts which in turn results in smarter and more reusable content.
Mermaid, as a text-based diagramming tool allows for quick and easy updates and makes documentation much easier. It can also be included in production scripts and other pieces of code as per requirement.

Even non-programmers can create diagrams through the [Mermaid Live Editor](https://github.com/mermaid-js/mermaid-live-editor), Visit the [Tutorials Page](./Tutorials.md) for the Live Editor video tutorials.
Many editors, wikis and other tools also have mermaid integrations and plugins, making it easy to start using mermaid. A few of those are described in [Simple start to write diagrams](./n00b-gettingStarted.md).

# Tutorials
This is list of publicly available Tutorials for using Mermaid.JS . This is intended as a basic introduction for the use of the Live Editor for generating diagrams, and deploying Mermaid.JS through HTML.
**Note that these tutorials might display an older interface, but the usage of the live-editor will largely be the same.**
For most purposes, you can use the [Live Editor](https://mermaid-js.github.io/mermaid-live-editor), to quickly and easily render a diagram.
## Live-Editor Tutorials
The definitions that can be generated the Live-Editor are also backwards-compatible as of version 8.7.0.

## Jupyter Integration with mermaid-js
Here's an example of Python integration with mermaid-js which uses the mermaid.ink service, that displays the graph in a Jupyter notebook.
```python
import base64
from IPython.display import Image, display
import matplotlib.pyplot as plt
def mm(graph):
graphbytes = graph.encode("ascii")
base64_bytes = base64.b64encode(graphbytes)
base64_string = base64_bytes.decode("ascii")
display(Image(url="https://mermaid.ink/img/" + base64_string))
mm("""
graph LR;
A--> B & C & D;
B--> A & E;
C--> A & E;
D--> A & E;
E--> B & C & D;
""")
```

# Breaking changes
### Breaking changes from history version to latest version:
## #1
```javascript
mermaid.initialize({
sequenceDiagram:{
...
}
})
```
has been changed to
```javascript
mermaid.initialize({
sequence:{
...
}
})
```
## #2
In old versions you need to add CSS file to your HTML:
```html
<link rel="stylesheet" href="mermaid.min.css">
```
or
```html
<link rel="stylesheet" href="mermaid.forest.min.css">
```
Now it is not needed to do so. And there are no more CSS files in distrubtion files.
You just
```javascript
mermaid.initialize({
theme: 'forest'
})
```
and it works like a charm.
This is because now the CSS is inline with SVG for portability.

# Class diagrams
> "In software engineering, a class diagram in the Unified Modeling Language (UML) is a type of static structure diagram that describes the structure of a system by showing the system's classes, their attributes, operations (or methods), and the relationships among objects."
> Wikipedia
The class diagram is the main building block of object-oriented modeling. It is used for general conceptual modeling of the structure of the application, and for detailed modeling translating the models into programming code. Class diagrams can also be used for data modeling. The classes in a class diagram represent both the main elements, interactions in the application, and the classes to be programmed.
Mermaid can render class diagrams.
```mermaid-example
classDiagram
Animal <|-- Duck
Animal <|-- Fish
Animal <|-- Zebra
Animal : +int age
Animal : +String gender
Animal: +isMammal()
Animal: +mate()
class Duck{
+String beakColor
+swim()
+quack()
}
class Fish{
-int sizeInFeet
-canEat()
}
class Zebra{
+bool is_wild
+run()
}
```
## Syntax
### Class
UML provides mechanisms to represent class members, such as attributes and methods, and additional information about them.
A single instance of a class in the diagram contains three compartments:
- The top compartment contains the name of the class. It is printed in bold and centered, and the first letter is capitalized. It may also contain optional annotation text describing the nature of the class.
- The middle compartment contains the attributes of the class. They are left-aligned and the first letter is lowercase.
- The bottom compartment contains the operations the class can execute. They are also left-aligned and the first letter is lowercase.
```mermaid-example
classDiagram
class BankAccount
BankAccount : +String owner
BankAccount : +Bigdecimal balance
BankAccount : +deposit(amount)
BankAccount : +withdrawl(amount)
```
## Define a class
There are two ways to define a class:
- Explicitly defining a class using keyword **class** like `class Animal`. This defines the Animal class
- Define two classes via a **relationship** between them `Vehicle <|-- Car`. This defines two classes Vehicle and Car along with their relationship.
```mermaid-example
classDiagram
class Animal
Vehicle <|-- Car
```
Naming convention: a class name should be composed of alphanumeric (unicode allowed) and underscore characters.
## Defining Members of a class
UML provides mechanisms to represent class members, such as attributes and methods, and additional information about them.
Mermaid distinguishes between attributes and functions/methods based on if the **parenthesis** `()` are present or not. The ones with `()` are treated as functions/methods, and others as attributes.
There are two ways to define the members of a class, and regardless of whichever syntax is used to define the members, the output will still be same. The two different ways are :
- Associate a member of a class using **:** (colon) followed by member name, useful to define one member at a time. For example:
```mermaid-example
classDiagram
class BankAccount
BankAccount : +String owner
BankAccount : +BigDecimal balance
BankAccount : +deposit(amount)
BankAccount : +withdrawal(amount)
```
- Associate members of a class using **{}** brackets, where members are grouped within curly brackets. Suitable for defining multiple members at once. For example:
```mermaid-example
classDiagram
class BankAccount{
+String owner
+BigDecimal balance
+deposit(amount)
+withdrawl(amount)
}
```
#### Return Type
Optionally you can end the method/function definition with the data type that will be returned (note: there must be a space between the final `)` of the method definition and return type
example:
```mermaid-example
classDiagram
class BankAccount{
+String owner
+BigDecimal balance
+deposit(amount) bool
+withdrawl(amount) int
}
```
#### Generic Types
Members can be defined using generic types, such as `List<int>`, for fields, parameters and return types by enclosing the type within `~` (**tilde**). Note: **nested** type declarations (such as `List<List<int>>`) are not currently supported
This can be done as part of either class definition method:
```mermaid-example
classDiagram
class Square~Shape~{
int id
List~int~ position
setPoints(List~int~ points)
getPoints() List~int~
}
Square : -List~string~ messages
Square : +setMessages(List~string~ messages)
Square : +getMessages() List~string~
```
#### Return Type
Optionally you can end the method/function definition with the data type that will be returned
#### Visibility
To specify the visibility of a class member (i.e. any attribute or method), these notations may be placed before the member's name, but it is optional:
- `+` Public
- `-` Private
- `#` Protected
- `~` Package/Internal
> _note_ you can also include additional _classifiers_ to a method definition by adding the following notations to the end of the method, i.e.: after the `()`:
> - `*` Abstract e.g.: `someAbstractMethod()*`
> - `$` Static e.g.: `someStaticMethod()$`
> _note_ you can also include additional _classifiers_ to a field definition by adding the following notations to the end of the field name:
> - `$` Static e.g.: `String someField$`
## Defining Relationship
A relationship is a general term covering the specific types of logical connections found on class and object diagrams.
```
[classA][Arrow][ClassB]
```
There are different types of relations defined for classes under UML which are currently supported:
| Type | Description |
| ----- | ------------- |
| <\|-- | Inheritance |
| \*-- | Composition |
| o-- | Aggregation |
| --> | Association |
| -- | Link (Solid) |
| ..> | Dependency |
| ..\|> | Realization |
| .. | Link (Dashed) |
```mermaid-example
classDiagram
classA <|-- classB
classC *-- classD
classE o-- classF
classG <-- classH
classI -- classJ
classK <.. classL
classM <|.. classN
classO .. classP
```
We can use the labels to describe nature of relation between two classes. Also, arrowheads can be used in opposite directions as well :
```mermaid-example
classDiagram
classA --|> classB : Inheritance
classC --* classD : Composition
classE --o classF : Aggregation
classG --> classH : Association
classI -- classJ : Link(Solid)
classK ..> classL : Dependency
classM ..|> classN : Realization
classO .. classP : Link(Dashed)
```
### Labels on Relations
It is possible to add a label text to a relation:
```
[classA][Arrow][ClassB]:LabelText
```
```mermaid-example
classDiagram
classA <|-- classB : implements
classC *-- classD : composition
classE o-- classF : association
```
### Two-way relations
Relations can go in multiple ways:
```mmd
classDiagram
Animal <|--|> Zebra
```
Here is the syntax:
```
[Relation Type][Link][Relation Type]
```
Where `Relation Type` can be one of:
| Type | Description |
| ---- | ----------- |
| <\| | Inheritance |
| \* | Composition |
| o | Aggregation |
| > | Association |
| < | Association |
| \|> | Realization |
And `Link` can be one of:
| Type | Description |
| ---- | ----------- |
| -- | Solid |
| .. | Dashed |
## Cardinality / Multiplicity on relations
Multiplicity or cardinality in class diagrams indicates the number of instances of one class linked to one instance of the other class. For example, one company will have one or more employees, but each employee works for just one company.
Multiplicity notations are placed near the ends of an association.
The different cardinality options are :
- `1` Only 1
- `0..1` Zero or One
- `1..*` One or more
- `*` Many
- `n` n {where n>1}
- `0..n` zero to n {where n>1}
- `1..n` one to n {where n>1}
Cardinality can be easily defined by placing cardinality text within quotes `"` before(optional) and after(optional) a given arrow.
```
[classA] "cardinality1" [Arrow] "cardinality2" [ClassB]:LabelText
```
```mermaid-example
classDiagram
Customer "1" --> "*" Ticket
Student "1" --> "1..*" Course
Galaxy --> "many" Star : Contains
```
## Annotations on classes
It is possible to annotate classes with a specific marker text which is like meta-data for the class, giving a clear indication about its nature. Some common annotations examples could be:
- `<<Interface>>` To represent an Interface class
- `<<abstract>>` To represent an abstract class
- `<<Service>>` To represent a service class
- `<<enumeration>>` To represent an enum
Annotations are defined within the opening `<<` and closing `>>`. There are two ways to add an annotation to a class and regardless of the syntax used output will be same. The two ways are :
- In a **_separate line_** after a class is defined. For example:
```mermaid-example
classDiagram
class Shape
<<interface>> Shape
Shape : noOfVertices
Shape : draw()
```
- In a **_nested structure_** along with class definition. For example:
```mermaid-example
classDiagram
class Shape{
<<interface>>
noOfVertices
draw()
}
class Color{
<<enumeration>>
RED
BLUE
GREEN
WHITE
BLACK
}
```
## Comments
Comments can be entered within a class diagram, which will be ignored by the parser. Comments need to be on their own line, and must be prefaced with `%%` (double percent signs). Any text after the start of the comment to the next newline will be treated as a comment, including any class diagram syntax
```mmd
classDiagram
%% This whole line is a comment classDiagram class Shape <<interface>>
class Shape{
<<interface>>
noOfVertices
draw()
}
```
## Setting the direction of the diagram
With class diagrams you can use the direction statement to set the direction which the diagram will render like in this example.
```mermaid-example
classDiagram
direction RL
class Student {
-idCard : IdCard
}
class IdCard{
-id : int
-name : string
}
class Bike{
-id : int
-name : string
}
Student "1" --o "1" IdCard : carries
Student "1" --o "1" Bike : rides
```
## Interaction
It is possible to bind a click event to a node, the click can lead to either a javascript callback or to a link which will be opened in a new browser tab. **Note**: This functionality is disabled when using `securityLevel='strict'` and enabled when using `securityLevel='loose'`.
You would define these actions on a separate line after all classes have been declared.
```
action className "reference" "tooltip"
click className call callback() "tooltip"
click className href "url" "tooltip"
```
- _action_ is either `link` or `callback`, depending on which type of interaction you want to have called
- _className_ is the id of the node that the action will be associated with
- _reference_ is either the url link, or the function name for callback.
- (_optional_) tooltip is a string to be displayed when hovering over element (note: The styles of the tooltip are set by the class .mermaidTooltip.)
- note: callback function will be called with the nodeId as parameter.
### Examples
_URL Link:_
```mmd
classDiagram
class Shape
link Shape "http://www.github.com" "This is a tooltip for a link"
class Shape2
click Shape2 href "http://www.github.com" "This is a tooltip for a link"
```
_Callback:_
```mmd
classDiagram
class Shape
callback Shape "callbackFunction" "This is a tooltip for a callback"
class Shape2
click Shape2 call callbackFunction() "This is a tooltip for a callback"
```
```html
<script>
var callbackFunction = function(){
alert('A callback was triggered');
}
<script>
```
```mermaid
classDiagram
class Class01
class Class02
callback Class01 "callbackFunction" "Callback tooltip"
link Class02 "http://www.github.com" "This is a link"
class Class03
class Class04
click Class03 call callbackFunction() "Callback tooltip"
click Class04 href "http://www.github.com" "This is a link"
```
> **Success** The tooltip functionality and the ability to link to urls are available from version 0.5.2.
Beginners tip, a full example using interactive links in an html context:
```html
<body>
<div class="mermaid">
classDiagram
Animal <|-- Duck
Animal <|-- Fish
Animal <|-- Zebra
Animal : +int age
Animal : +String gender
Animal: +isMammal()
Animal: +mate()
class Duck{
+String beakColor
+swim()
+quack()
}
class Fish{
-int sizeInFeet
-canEat()
}
class Zebra{
+bool is_wild
+run()
}
callback Duck callback "Tooltip"
link Zebra "http://www.github.com" "This is a link"
</div>
<script>
var callback = function(){
alert('A callback was triggered');
}
var config = {
startOnLoad:true,
securityLevel:'loose',
};
mermaid.initialize(config);
</script>
</body>
```
## Styling
### Styling a node
It is possible to apply specific styles such as a thicker border or a different background color to individual nodes. This is done by predefining classes in css styles that can be applied from the graph definition as in the example
below:
```html
<style>
.cssClass > rect{
fill:#FF0000;
stroke:#FFFF00;
stroke-width:4px;
}
</style>
```
Then attaching that class to a specific node as per below:
```
cssClass "nodeId1" cssClass;
```
It is also possible to attach a class to a list of nodes in one statement:
```
cssClass "nodeId1,nodeId2" cssClass;
```
A shorter form of adding a class is to attach the classname to the node using the `:::` operator as per below:
```mmd
classDiagram
class Animal:::cssClass
```
Or:
```mmd
classDiagram
class Animal:::cssClass {
-int sizeInFeet
-canEat()
}
```
?> cssClasses cannot be added using this shorthand method at the same time as a relation statement.
?> Due to limitations with existing markup for class diagrams, it is not currently possible to define css classes within the diagram itself. ***Coming soon!***
### Default Styles
The main styling of the class diagram is done with a preset number of css classes. During rendering these classes are extracted from the file located at src/themes/class.scss. The classes used here are described below:
| Class | Description |
| ------------------ | ----------------------------------------------------------------- |
| g.classGroup text | Styles for general class text |
| classGroup .title | Styles for general class title |
| g.classGroup rect | Styles for class diagram rectangle |
| g.classGroup line | Styles for class diagram line |
| .classLabel .box | Styles for class label box |
| .classLabel .label | Styles for class label text |
| composition | Styles for composition arrow head and arrow line |
| aggregation | Styles for aggregation arrow head and arrow line(dashed or solid) |
| dependency | Styles for dependency arrow head and arrow line |
#### Sample stylesheet
```scss
body {
background: white;
}
g.classGroup text {
fill: $nodeBorder;
stroke: none;
font-family: 'trebuchet ms', verdana, arial;
font-family: var(--mermaid-font-family);
font-size: 10px;
.title {
font-weight: bolder;
}
}
g.classGroup rect {
fill: $nodeBkg;
stroke: $nodeBorder;
}
g.classGroup line {
stroke: $nodeBorder;
stroke-width: 1;
}
.classLabel .box {
stroke: none;
stroke-width: 0;
fill: $nodeBkg;
opacity: 0.5;
}
.classLabel .label {
fill: $nodeBorder;
font-size: 10px;
}
.relation {
stroke: $nodeBorder;
stroke-width: 1;
fill: none;
}
@mixin composition {

# Configuration
When mermaid starts configuration is extracted to a configuration to be used for a diagram. There a 3 sources for configuration:
* The default configuration
* Overrides on the site level, set is set by the initialize call and will be applied for all diagrams in the site/app. The term for this is the **siteConfig**.
* Directives - diagram authors can update select configuration parameters directly int he diagram code via directives and these are applied to the render config.
**The render config** is configuration that is used when rendering by applying these configurations.
## Theme configuration
## Starting mermaid
```mermaid
sequenceDiagram
Site->>mermaid: initialize
Site->>mermaid: content loaded
mermaid->>mermaidAPI: init
```
## Initialize
Intialize call is calloed **only once**. It is called by the site integrator in order to override the default configuration on a site level.
## configApi.reset
This method resets the configuration for a diagram to the site configuration, the configuration provided by the site integrator. Before each rendering of a diagram reset is called in the very beginning of render.

# Development and Contribution 🙌
So you want to help? That's great!
![Image of happy people jumping with excitement](https://media.giphy.com/media/BlVnrxJgTGsUw/giphy.gif)
Here are a few things to know to get you started on the right path.
**The Docs Structure is dictated by [sidebar.md](https://github.com/mermaid-js/mermaid/edit/develop/docs/_sidebar.md)**
**Note: Commits and Pull Requests should be directed to the develop branch.**
## Branching
Mermaid uses a [Git Flow](https://guides.github.com/introduction/flow/)inspired approach to branching. So development is done in the `develop` branch.
Once development is done we branch a `release` branch from `develop` for testing.
Once the release happens we merge the `release` branch with `master` and kill the `release` branch.
This means that **you should branch off your pull request from develop** and direct all Pull Requests to it.
## Contributing Code
We make all changes via Pull Requests. As we have many Pull Requests from developers new to mermaid, we have put in place a process, wherein *knsv, Knut Sveidqvist* is the primary reviewer of changes and merging pull requests. The process is as follows:
* Large changes reviewed by knsv or other developer asked to review by knsv
* Smaller, low-risk changes like dependencies, documentation, etc. can be merged by active collaborators
* Documentation (we encourage updates to the docs folder; you can submit them via direct commits)
When you commit code, create a branch with the following naming convention:
Start with the type, such as **feature** or **bug**, followed by the issue number for reference, and a text that describes the issue.
**One example:**
`feature/945_state_diagrams`
**Another example:**
`bug/123_nasty_bug_branch`
## Contributing to Documentation
If it is not in the documentation, it's like it never happened. Wouldn't that be sad? With all the effort that was put into the feature?
The docs are located in the `docs` folder and are written in Markdown. Just pick the right section and start typing. If you want to propose changes to the structure of the documentation, such as adding a new section or a new file you do that via the **[sidebar](https://github.com/mermaid-js/mermaid/edit/develop/docs/_sidebar.md)**.
> **All the documents displayed in the github.io page are listed in [sidebar.md](https://github.com/mermaid-js/mermaid/edit/develop/docs/_sidebar.md)**.
The contents of [https://mermaid-js.github.io/mermaid/](https://mermaid-js.github.io/mermaid/) are based on the docs from the `master` branch. Updates commited to the `master` branch are reflected in the [Mermaid Docs](https://mermaid-js.github.io/mermaid/) once released.
## How to Contribute to Documentation
We are a little less strict here, it is OK to commit directly in the `develop` branch if you are a collaborator.
The documentation is located in the `docs` directory and organized according to relevant subfolder.
We encourage contributions to the documentation at [mermaid-js/mermaid/docs](https://github.com/mermaid-js/mermaid/tree/develop/docs). We publish documentation using GitHub Pages with [Docsify](https://www.youtube.com/watch?v=TV88lp7egMw&t=3s)
### Add Unit Tests for Parsing
This is important so that, if someone that does not know about this great feature suggests a change to the grammar, they get notified early on when that change breaks the parser. Another important aspect is that, without proper parsing, tests refactoring is pretty much impossible.
### Add E2E Tests
This tests the rendering and visual apearance of the diagrams. This ensures that the rendering of that feature in the e2e will be reviewed in the release process going forward. Less chance that it breaks!
To start working with the e2e tests:
1. Run `yarn dev` to start the dev server
2. Start **Cypress** by running `cypress open` in the **mermaid** folder.
(Make sure you have path to Cypress in order, the binary is located in `node_modules/.bin`).
The rendering tests are very straightforward to create. There is a function `imgSnapshotTest`, which takes a diagram in text form and the mermaid options, and it renders that diagram in Cypress.
When running in CI it will take a snapshot of the rendered diagram and compare it with the snapshot from last build and flag it for review if it differs.
This is what a rendering test looks like:
```js
it('should render forks and joins', () => {
imgSnapshotTest(
`
stateDiagram
state fork_state &lt;&lt;fork&gt;&gt;
[*] --> fork_state
fork_state --> State2
fork_state --> State3
state join_state &lt;&lt;join&gt;&gt;
State2 --> join_state
State3 --> join_state
join_state --> State4
State4 --> [*]
`,
{ logLevel: 0 }
);
cy.get('svg');
});
```

# Directives
**Edit this Page** [![N|Solid](img/GitHub-Mark-32px.png)](https://github.com/mermaid-js/mermaid/blob/develop/docs/directives.md)
## Directives
Directives gives a diagram author the capability to alter the appearance of a diagram before rendering by changing the applied configuration.
Directives are divided into two sets or orders, by priority in parsing. The first set, containing 'init' or 'initialize' directives are loaded ahead of any other directive. While the other set, containing all other kinds of directives are parsed and factored into the rendering, only after 'init' and the desired graph-type are declared.
### Init
| Parameter | Description |Type | Required | Values|
| --- | --- | --- | --- | --- |
| init | modifies configurations| Directive| Optional | Any parameters not included in the secure array|
**Notes:**
init would be an argument-directive: %%{init: { **insert argument here**}}%%
The json object that is passed as {**argument** } must be valid key value pairs and encased in quotation marks or it will be ignored.
Valid Key Value pairs can be found in config.
The init/initialize directive is parsed earlier in the flow, this allows the incorporation of `%%init%%` directives into the mermaid diagram that is being rendered. Example:
```mmd
%%{init: { 'logLevel': 'debug', 'theme': 'dark' } }%%
graph >
A-->B
```
will set the `logLevel` to `debug` and the `theme` to `dark` for a flowchart diagram, changing the appearance of the diagram itself.
Note: 'init' or 'initialize' are both acceptable as init directives. Also note that `%%init%%` and `%%initialize%%` directives will be grouped together after they are parsed. This means:
```mmd2
%%{init: { 'logLevel': 'debug', 'theme': 'forest' } }%%
%%{initialize: { 'logLevel': 'fatal', "theme":'dark', 'startOnLoad': true } }%%
...
```
parsing the above generates the `%%init%%` object below, combining the two directives and carrying over the last value given for `loglevel`:
```json5
{
logLevel: 'fatal',
theme: 'dark',
startOnLoad: true
}
```
This will then be sent to `mermaid.initialize(...)` for rendering.
### Other directives
In this category are any directives that come after the graph type declaration. Essentially, these directives will only be processed after the init directive. Each individual graph type will handle these directives. As an example:
```
%%{init: { 'logLevel': 'debug', 'theme': 'dark' } }%%
sequenceDiagram
%%{config: { 'fontFamily': 'Menlo', 'fontSize': 18, 'fontWeight': 400} }%%
Alice->>Bob: Hi Bob
Bob->>Alice: Hi Alice
```
## Chronology
This will set the `logLevel` to `debug` and `theme` to `dark` for a sequence diagram. Then, during processing, the config for the sequence diagram is set by the `config` directive. This directive is handled in the `sequenceDb.js`. In this example, the fontFamily, fontSize, and fontWeight are all set for this sequence diagram.
### Wrapping
## Wrap
| Parameter | Description |Type | Required | Values|
| --- | --- | --- | --- | --- |
| wrap | a callable text-wrap function| Directive| Optional | %%{wrap}%%|
#### Backwards Compatibility
Init directives and any other non-multiline directives should be backwards compatible, because they will be treated as comments in prior versions of mermaid-js.
Multiline directives, however, will pose an issue and will render an error. This is unavoidable.

# Entity Relationship Diagrams
**Edit this Page** [![N|Solid](img/GitHub-Mark-32px.png)](https://github.com/mermaid-js/mermaid/blob/develop/docs/entityRelationshipDiagram.md)
> An entityrelationship model (or ER model) describes interrelated things of interest in a specific domain of knowledge. A basic ER model is composed of entity types (which classify the things of interest) and specifies relationships that can exist between entities (instances of those entity types). Wikipedia.
Note that practitioners of ER modelling almost always refer to *entity types* simply as *entities*. For example the `CUSTOMER` entity *type* would be referred to simply as the `CUSTOMER` entity. This is so common it would be inadvisable to do anything else, but technically an entity is an abstract *instance* of an entity type, and this is what an ER diagram shows - abstract instances, and the relationships between them. This is why entities are always named using singular nouns.
Mermaid can render ER diagrams
```mermaid-example
erDiagram
CUSTOMER ||--o{ ORDER : places
ORDER ||--|{ LINE-ITEM : contains
CUSTOMER }|..|{ DELIVERY-ADDRESS : uses
```
Entity names are often capitalised, although there is no accepted standard on this, and it is not required in Mermaid.
Relationships between entities are represented by lines with end markers representing cardinality. Mermaid uses the most popular crow's foot notation. The crow's foot intuitively conveys the possibility of many instances of the entity that it connects to.
ER diagrams can be used for various purposes, ranging from abstract logical models devoid of any implementation details, through to physical models of relational database tables. It can be useful to include attribute definitions on ER diagrams to aid comprehension of the purpose and meaning of entities. These do not necessarily need to be exhaustive; often a small subset of attributes is enough. Mermaid allows to be defined in terms of their *type* and *name*.
```mermaid-example
erDiagram
CUSTOMER ||--o{ ORDER : places
CUSTOMER {
string name
string custNumber
string sector
}
ORDER ||--|{ LINE-ITEM : contains
ORDER {
int orderNumber
string deliveryAddress
}
LINE-ITEM {
string productCode
int quantity
float pricePerUnit
}
```
When including attributes on ER diagrams, you must decide whether to include foreign keys as attributes. This probably depends on how closely you are trying to represent relational table structures. If your diagram is a *logical* model which is not meant to imply a relational implementation, then it is better to leave these out because the associative relationships already convey the way that entities are associated. For example, a JSON data structure can implement a one-to-many relationship without the need for foreign key properties, using arrays. Similarly an object-oriented programming language may use pointers or references to collections. Even for models that are intended for relational implementation, you might decide that inclusion of foreign key attributes duplicates information already portrayed by the relationships, and does not add meaning to entities. Ultimately, it's your choice.
## Syntax
### Entities and Relationships
Mermaid syntax for ER diagrams is compatible with PlantUML, with an extension to label the relationship. Each statement consists of the following parts:
```
<first-entity> [<relationship> <second-entity> : <relationship-label>]
```
Where:
- `first-entity` is the name of an entity. Names must begin with an alphabetic character and may also contain digits, hyphens, and underscores.
- `relationship` describes the way that both entities inter-relate. See below.
- `second-entity` is the name of the other entity.
- `relationship-label` describes the relationship from the perspective of the first entity.
For example:
```
PROPERTY ||--|{ ROOM : contains
```
This statement can be read as *a property contains one or more rooms, and a room is part of one and only one property*. You can see that the label here is from the first entity's perspective: a property contains a room, but a room does not contain a property. When considered from the perspective of the second entity, the equivalent label is usually very easy to infer. (Some ER diagrams label relationships from both perspectives, but this is not supported here, and is usually superfluous).
Only the `first-entity` part of a statement is mandatory. This makes it possible to show an entity with no relationships, which can be useful during iterative construction of diagrams. If any other parts of a statement are specified, then all parts are mandatory.
### Relationship Syntax
The `relationship` part of each statement can be broken down into three sub-components:
- the cardinality of the first entity with respect to the second,
- whether the relationship confers identity on a 'child' entity
- the cardinality of the second entity with respect to the first
Cardinality is a property that describes how many elements of another entity can be related to the entity in question. In the above example a `PROPERTY` can have one or more `ROOM` instances associated to it, whereas a `ROOM` can only be associated with one `PROPERTY`. In each cardinality marker there are two characters. The outermost character represents a maximum value, and the innermost character represents a minimum value. The table below summarises possible cardinalities.
| Value (left) | Value (right) | Meaning |
|:------------:|:-------------:|--------------------------------------------------------|
| `\|o` | `o\|` | Zero or one |
| `\|\|` | `\|\|` | Exactly one |
| `}o` | `o{` | Zero or more (no upper limit) |
| `}\|` | `\|{` | One or more (no upper limit) |
### Identification
Relationships may be classified as either *identifying* or *non-identifying* and these are rendered with either solid or dashed lines respectively. This is relevant when one of the entities in question can not have independent existence without the other. For example a firm that insures people to drive cars might need to store data on `NAMED-DRIVER`s. In modelling this we might start out by observing that a `CAR` can be driven by many `PERSON` instances, and a `PERSON` can drive many `CAR`s - both entities can exist without the other, so this is a non-identifying relationship that we might specify in Mermaid as: `PERSON }|..|{ CAR : "driver"`. Note the two dots in the middle of the relationship that will result in a dashed line being drawn between the two entities. But when this many-to-many relationship is resolved into two one-to-many relationships, we observe that a `NAMED-DRIVER` cannot exist without both a `PERSON` and a `CAR` - the relationships become identifying and would be specified using hyphens, which translate to a solid line:
```mmd
erDiagram
CAR ||--o{ NAMED-DRIVER : allows
PERSON ||--o{ NAMED-DRIVER : is
```
### Attributes
Attributes can be defined for entities by specifying the entity name followed by a block containing multiple `type name` pairs, where a block is delimited by an opening `{` and a closing `}`. For example:
```mermaid-example
erDiagram
CAR ||--o{ NAMED-DRIVER : allows
CAR {
string registrationNumber
string make
string model
}
PERSON ||--o{ NAMED-DRIVER : is
PERSON {
string firstName
string lastName
int age
}
```
The attributes are rendered inside the entity boxes:
```mermaid-example
erDiagram
CAR ||--o{ NAMED-DRIVER : allows
CAR {
string registrationNumber
string make
string model
}
PERSON ||--o{ NAMED-DRIVER : is
PERSON {
string firstName
string lastName
int age
}
```
The `type` and `name` values must begin with an alphabetic character and may contain digits, hyphens or underscores. Other than that, there are no restrictions, and there is no implicit set of valid data types.
#### Attribute Keys and Comments
Attributes may also have a `key` or comment defined. Keys can be "PK" or "FK", for Primary Key or Foreign Key. And a `comment` is defined by double quotes at the end of an attribute. Comments themselves cannot have double-quote characters in them.
```mermaid-example
erDiagram
CAR ||--o{ NAMED-DRIVER : allows
CAR {
string allowedDriver FK "The license of the allowed driver"
string registrationNumber
string make
string model
}
PERSON ||--o{ NAMED-DRIVER : is
PERSON {
string driversLicense PK "The license #"
string firstName
string lastName
int age
}
```
### Other Things
- If you want the relationship label to be more than one word, you must use double quotes around the phrase
- If you don't want a label at all on a relationship, you must use an empty double-quoted string
## Styling
### Config options
For simple color customization:
| Name | Used as |
| :------- | :------------------------------------------------------------------- |
| `fill` | Background color of an entity or attribute |
| `stroke` | Border color of an entity or attribute, line color of a relationship |
### Classes used
The following CSS class selectors are available for richer styling:
| Selector | Description |
| :------------------------- | :---------------------------------------------------- |
| `.er.attributeBoxEven` | The box containing attributes on even-numbered rows |
| `.er.attributeBoxOdd` | The box containing attributes on odd-numbered rows |
| `.er.entityBox` | The box representing an entity |
| `.er.entityLabel` | The label for an entity |
| `.er.relationshipLabel` | The label for a relationship |
| `.er.relationshipLabelBox` | The box surrounding a relationship label |
| `.er.relationshipLine` | The line representing a relationship between entities |

# Flowcharts - Basic Syntax
**Edit this Page** [![N|Solid](img/GitHub-Mark-32px.png)](https://github.com/mermaid-js/mermaid/blob/develop/docs/flowchart.md)
All Flowcharts are composed of **nodes**, the geometric shapes and **edges**, the arrows or lines. The mermaid code defines the way that these **nodes** and **edges** are made and interact.
It can also accomodate different arrow types, multi directional arrows, and linking to and from subgraphs.
> **Important note**: Do not type the word "end" as a Flowchart node. Capitalize all or any one the letters to keep the flowchart from breaking, i.e, "End" or "END". Or you can apply this [workaround](https://github.com/mermaid-js/mermaid/issues/1444#issuecomment-639528897).**
Node
### A node (default)
```mermaid-example
flowchart LR
id
```
> **Note** The id is what is displayed in the box.
### A node with text
It is also possible to set text in the box that differs from the id. If this is done several times, it is the last text
found for the node that will be used. Also if you define edges for the node later on, you can omit text definitions. The
one previously defined will be used when rendering the box.
```mermaid-example
flowchart LR
id1[This is the text in the box]
```
## Graph
This statement declares the direction of the Flowchart.
This declares the flowchart is oriented from top to bottom (`TD` or `TB`).
```mermaid-example
flowchart TD
Start --> Stop
```
This declares the flowchart is oriented from left to right (`LR`).
```mermaid-example
flowchart LR
Start --> Stop
```
## Flowchart Orientation
Possible FlowChart orientations are:
* TB - top to bottom
* TD - top-down/ same as top to bottom
* BT - bottom to top
* RL - right to left
* LR - left to right
## Node shapes
### A node with round edges
```mermaid-example
flowchart LR
id1(This is the text in the box)
```
### A stadium-shaped node
```mermaid-example
flowchart LR
id1([This is the text in the box])
```
### A node in a subroutine shape
```mermaid-example
flowchart LR
id1[[This is the text in the box]]
```
### A node in a cylindrical shape
```mermaid-example
flowchart LR
id1[(Database)]
```
### A node in the form of a circle
```mermaid-example
flowchart LR
id1((This is the text in the circle))
```
### A node in an asymmetric shape
```mermaid-example
flowchart LR
id1>This is the text in the box]
```
Currently only the shape above is possible and not its mirror. *This might change with future releases.*
### A node (rhombus)
```mermaid-example
flowchart LR
id1{This is the text in the box}
```
### A hexagon node
```mermaid-example
flowchart LR
id1{{This is the text in the box}}
```
### Parallelogram
```mermaid-example
flowchart TD
id1[/This is the text in the box/]
```
### Parallelogram alt
```mermaid-example
flowchart TD
id1[\This is the text in the box\]
```
### Trapezoid
```mermaid-example
flowchart TD
A[/Christmas\]
```
### Trapezoid alt
```mermaid-example
flowchart TD
B[\Go shopping/]
```
## Links between nodes
Nodes can be connected with links/edges. It is possible to have different types of links or attach a text string to a link.
### A link with arrow head
```mermaid-example
flowchart LR
A-->B
```
### An open link
```mermaid-example
flowchart LR
A --- B
```
### Text on links
```mermaid-example
flowchart LR
A-- This is the text! ---B
```
or
```mermaid-example
flowchart LR
A---|This is the text|B
```
### A link with arrow head and text
```mermaid-example
flowchart LR
A-->|text|B
```
or
```mermaid-example
flowchart LR
A-- text -->B
```
### Dotted link
```mermaid-example
flowchart LR;
A-.->B;
```
### Dotted link with text
```mermaid-example
flowchart LR
A-. text .-> B
```
### Thick link
```mermaid-example
flowchart LR
A ==> B
```
### Thick link with text
```mermaid-example
flowchart LR
A == text ==> B
```
### Chaining of links
It is possible declare many links in the same line as per below:
```mermaid-example
flowchart LR
A -- text --> B -- text2 --> C
```
It is also possible to declare multiple nodes links in the same line as per below:
```mermaid-example
flowchart LR
a --> b & c--> d
```
You can then describe dependencies in a very expressive way. Like the one-liner below:
```mermaid-example
flowchart TB
A & B--> C & D
```
If you describe the same diagram using the the basic syntax, it will take four lines. A
word of warning, one could go overboard with this making the flowchart harder to read in
markdown form. The Swedish word `lagom` comes to mind. It means, not too much and not too little.
This goes for expressive syntaxes as well.
```mmd
flowchart TB
A --> C
A --> D
B --> C
B --> D
```
### New arrow types
There are new types of arrows supported as per below:
```mermaid-example
flowchart LR
A --o B
B --x C
```
### Multi directional arrows
There is the possibility to use multidirectional arrows.
```mermaid-example
flowchart LR
A o--o B
B <--> C
C x--x D
```
### Minimum length of a link
Each node in the flowchart is ultimately assigned to a rank in the rendered
graph, i.e. to a vertical or horizontal level (depending on the flowchart
orientation), based on the nodes to which it is linked. By default, links
can span any number of ranks, but you can ask for any link to be longer
than the others by adding extra dashes in the link definition.
In the following example, two extra dashes are added in the link from node _B_
to node _E_, so that it spans two more ranks than regular links:
```mermaid-example
flowchart TD
A[Start] --> B{Is it?};
B -->|Yes| C[OK];
C --> D[Rethink];
D --> B;
B ---->|No| E[End];
```
> **Note** Links may still be made longer than the requested number of ranks
> by the rendering engine to accommodate other requests.
When the link label is written in the middle of the link, the extra dashes must
be added on the right side of the link. The following example is equivalent to
the previous one:
```mermaid-example
flowchart TD
A[Start] --> B{Is it?};
B -- Yes --> C[OK];
C --> D[Rethink];
D --> B;
B -- No ----> E[End];
```
For dotted or thick links, the characters to add are equals signs or dots,
as summed up in the following table:
| Length | 1 | 2 | 3 |
|-------------------|:------:|:-------:|:--------:|
| Normal | `---` | `----` | `-----` |
| Normal with arrow | `-->` | `--->` | `---->` |
| Thick | `===` | `====` | `=====` |
| Thick with arrow | `==>` | `===>` | `====>` |
| Dotted | `-.-` | `-..-` | `-...-` |
| Dotted with arrow | `-.->` | `-..->` | `-...->` |
## Special characters that break syntax
It is possible to put text within quotes in order to render more troublesome characters. As in the example below:
```mermaid-example
flowchart LR
id1["This is the (text) in the box"]
```
### Entity codes to escape characters
It is possible to escape characters using the syntax exemplified here.
```mermaid-example
flowchart LR
A["A double quote:#quot;"] -->B["A dec char:#9829;"]
```
Numbers given are base 10, so `#` can be encoded as `#35;`. It is also supported to use HTML character names.
## Subgraphs
```
subgraph title
graph definition
end
```
An example below:
```mermaid-example
flowchart TB
c1-->a2
subgraph one
a1-->a2
end
subgraph two
b1-->b2
end
subgraph three
c1-->c2
end
```
You can also set an explicit id for the subgraph.
```mermaid-example
flowchart TB
c1-->a2
subgraph ide1 [one]
a1-->a2
end
```
## Beta: flowcharts
With the graphtype flowcharts it is also possible to set edges to and from subgraphs as in the flowchart below.
```mermaid-example
flowchart TB
c1-->a2
subgraph one
a1-->a2
end
subgraph two
b1-->b2
end
subgraph three
c1-->c2
end
one --> two
three --> two
two --> c2
```
## Direction in subgraphs
With the graphtype flowcharts you can use the direction statement to set the direction which the subgraph will render like in this example.
```mermaid-example
flowchart LR
subgraph TOP
direction TB
subgraph B1
direction RL
i1 -->f1
end
subgraph B2
direction BT
i2 -->f2
end
end
A --> TOP --> B
B1 --> B2
```
## Interaction
It is possible to bind a click event to a node, the click can lead to either a javascript callback or to a link which will be opened in a new browser tab. **Note**: This functionality is disabled when using `securityLevel='strict'` and enabled when using `securityLevel='loose'`.
```
click nodeId callback
click nodeId call callback()
```
* nodeId is the id of the node
* callback is the name of a javascript function defined on the page displaying the graph, the function will be called with the nodeId as parameter.
Examples of tooltip usage below:
```html
<script>
var callback = function(){
alert('A callback was triggered');
}
</script>
```
The tooltip text is surrounded in double quotes. The styles of the tooltip are set by the class `.mermaidTooltip`.
```mermaid-example
flowchart LR;
A-->B;
B-->C;
C-->D;
click A callback "Tooltip for a callback"
click B "http://www.github.com" "This is a tooltip for a link"
click A call callback() "Tooltip for a callback"
click B href "http://www.github.com" "This is a tooltip for a link"
```
> **Success** The tooltip functionality and the ability to link to urls are available from version 0.5.2.
?> Due to limitations with how Docsify handles JavaScript callback functions, an alternate working demo for the above code can be viewed at [this jsfiddle](https://jsfiddle.net/s37cjoau/3/).
Links are opened in the same browser tab/window by default. It is possible to change this by adding a link target to the click definition (`_self`, `_blank`, `_parent` and `_top` are supported):
```mermaid-example
flowchart LR;
A-->B;
B-->C;
C-->D;
D-->E;
click A "http://www.github.com" _blank
click B "http://www.github.com" "Open this in a new tab" _blank
click C href "http://www.github.com" _blank
click D href "http://www.github.com" "Open this in a new tab" _blank
```
Beginners tip, a full example using interactive links in a html context:
```html
<body>
<div class="mermaid">
flowchart LR;
A-->B;
B-->C;
C-->D;
click A callback "Tooltip"
click B "http://www.github.com" "This is a link"
click C call callback() "Tooltip"
click D href "http://www.github.com" "This is a link"
</div>
<script>
var callback = function(){
alert('A callback was triggered');
}
var config = {
startOnLoad:true,
flowchart:{
useMaxWidth:true,
htmlLabels:true,
curve:'cardinal',
},
securityLevel:'loose',
};
mermaid.initialize(config);
</script>
</body>
```
### Comments
Comments can be entered within a flow diagram, which will be ignored by the parser. Comments need to be on their own line, and must be prefaced with `%%` (double percent signs). Any text after the start of the comment to the next newline will be treated as a comment, including any flow syntax
```mmd
flowchart LR
%% this is a comment A -- text --> B{node}
A -- text --> B -- text2 --> C
```
## Styling and classes
### Styling links
It is possible to style links. For instance you might want to style a link that is going backwards in the flow. As links
have no ids in the same way as nodes, some other way of deciding what style the links should be attached to is required.
Instead of ids, the order number of when the link was defined in the graph is used. In the example below the style
defined in the linkStyle statement will belong to the fourth link in the graph:
```
linkStyle 3 stroke:#ff3,stroke-width:4px,color:red;
```
### Styling a node
It is possible to apply specific styles such as a thicker border or a different background color to a node.
```mermaid-example
flowchart LR
id1(Start)-->id2(Stop)
style id1 fill:#f9f,stroke:#333,stroke-width:4px
style id2 fill:#bbf,stroke:#f66,stroke-width:2px,color:#fff,stroke-dasharray: 5 5
```
#### Classes
More convenient than defining the style every time is to define a class of styles and attach this class to the nodes that
should have a different look.
a class definition looks like the example below:
```
classDef className fill:#f9f,stroke:#333,stroke-width:4px;
```
Attachment of a class to a node is done as per below:
```
class nodeId1 className;
```
It is also possible to attach a class to a list of nodes in one statement:
```
class nodeId1,nodeId2 className;
```
A shorter form of adding a class is to attach the classname to the node using the `:::`operator as per below:
```mermaid-example
flowchart LR
A:::someclass --> B
classDef someclass fill:#f96;
```
### Css classes
It is also possible to predefine classes in css styles that can be applied from the graph definition as in the example
below:
**Example style**
```html
<style>
.cssClass > rect{
fill:#FF0000;
stroke:#FFFF00;
stroke-width:4px;
}
</style>
```
**Example definition**
```mermaid-example
flowchart LR;
A-->B[AAA<span>BBB</span>];
B-->D;
class A cssClass;
```
### Default class
If a class is named default it will be assigned to all classes without specific class definitions.
```
classDef default fill:#f9f,stroke:#333,stroke-width:4px;
```
## Basic support for fontawesome
It is possible to add icons from fontawesome.
The icons are accessed via the syntax fa:#icon class name#.
```mermaid-example
flowchart TD
B["fa:fa-twitter for peace"]
B-->C[fa:fa-ban forbidden]
B-->D(fa:fa-spinner);
B-->E(A fa:fa-camera-retro perhaps?);
```
## Graph declarations with spaces between vertices and link and without semicolon
* In graph declarations, the statements also can now end without a semicolon. After release 0.2.16, ending a graph statement with semicolon is just optional. So the below graph declaration is also valid along with the old declarations of the graph.
* A single space is allowed between vertices and the link. However there should not be any space between a vertex and its text and a link and its text. The old syntax of graph declaration will also work and hence this new feature is optional and is introduced to improve readability.
Below is the new declaration of the graph edges which is also valid along with the old declaration of the graph edges.
```mermaid-example
flowchart LR
A[Hard edge] -->|Link text| B(Round edge)
B --> C{Decision}
C -->|One| D[Result one]
C -->|Two| E[Result two]
```
## Configuration...
Is it possible to adjust the width of the rendered flowchart.
This is done by defining **mermaid.flowchartConfig** or by the CLI to use a json file with the configuration. How to use
the CLI is described in the mermaidCLI page.
mermaid.flowchartConfig can be set to a JSON string with config parameters or the corresponding object.
```javascript
mermaid.flowchartConfig = {
width: 100%
}
```

# Gantt diagrams
> A Gantt chart is a type of bar chart, first developed by Karol Adamiecki in 1896, and independently by Henry Gantt in the 1910s, that illustrates a project schedule and the amount of time it would take for any one project to finish. Gantt charts illustrate number of days between the start and finish dates of the terminal elements and summary elements of a project.
## A note to users
Gantt Charts will record each scheduled task as one continuous bar that extends from the left to the right. The x axis represents time and the y records the different tasks and the order in which they are to be completed.
It is important to remember that when a date, day, or collection of dates specific to a task are "excluded", the Gantt Chart will accomodate those changes by extending an equal number of days, towards the right, not by creating a gap inside the task.
As shown here ![](./img/Gantt-excluded-days-within.png)
However, if the excluded dates are between two tasks that are set to start consecutively, the excluded dates will be skipped graphically and left blank, and the following task will begin after the end of the excluded dates.
As shown here ![](./img/Gantt-long-weekend-look.png)
A Gantt chart is useful for tracking the amount of time it would take before a project is finished, but it can also be used to graphically represent "non-working days", with a few tweaks.
Mermaid can render Gantt diagrams as SVG, PNG or a MarkDown link that can be pasted into docs.
```mermaid-example
gantt
title A Gantt Diagram
dateFormat YYYY-MM-DD
section Section
A task :a1, 2014-01-01, 30d
Another task :after a1 , 20d
section Another
Task in sec :2014-01-12 , 12d
another task : 24d
```
## Syntax
```mermaid-example
gantt
dateFormat YYYY-MM-DD
title Adding GANTT diagram functionality to mermaid
excludes weekends
%% (`excludes` accepts specific dates in YYYY-MM-DD format, days of the week ("sunday") or "weekends", but not the word "weekdays".)
section A section

Add another diagram to demo page :doc1, after a1 , 48h
section Last section
Describe gantt syntax :after doc1, 3d
Add gantt diagram to demo page :20h
Add another diagram to demo page :48h
```
It is possible to set multiple dependencies separated by space:
```mermaid-example
gantt
apple :a, 2017-07-20, 1w
banana :crit, b, 2017-07-23, 1d
cherry :active, c, after b a, 1d
```
### Title
The `title` is an *optional* string to be displayed at the top of the Gantt chart to describe the chart as a whole.
### Section statements
You can divide the chart into various sections, for example to separate different parts of a project like development and documentation.
To do so, start a line with the `section` keyword and give it a name. (Note that unlike with the [title for the entire chart](#title), this name is *required*.
### Milestones
You can add milestones to the diagrams. Milestones differ from tasks as they represent a single instant in time and are identified by the keyword `milestone`. Below is an example on how to use milestones. As you may notice, the exact location of the milestone is determined by the initial date for the milestone and the "duration" of the task this way: *initial date*+*duration*/2.
```mermaid-example
gantt
dateFormat HH:mm
axisFormat %H:%M
Initial milestone : milestone, m1, 17:49,2min
taska2 : 10min
taska3 : 5min
Final milestone : milestone, m2, 18:14, 2min
```
## Setting dates
`dateFormat` defines the format of the date **input** of your gantt elements. How these dates are represented in the rendered chart **output** are defined by `axisFormat`.
### Input date format
The default input date format is `YYYY-MM-DD`. You can define your custom ``dateFormat``.
```
dateFormat YYYY-MM-DD
```
The following formating options are supported:

### Output date format on the axis
The default output date format is YYYY-MM-DD. You can define your custom ``axisFormat``, like `2020-Q1` for the first quarter of the year 2020.
```
axisFormat %Y-%m-%d
```
The following formating strings are supported:
```
%a - abbreviated weekday name.
%A - full weekday name.
%b - abbreviated month name.
%B - full month name.
%c - date and time, as "%a %b %e %H:%M:%S %Y".
%d - zero-padded day of the month as a decimal number [01,31].
%e - space-padded day of the month as a decimal number [ 1,31]; equivalent to %_d.
%H - hour (24-hour clock) as a decimal number [00,23].
%I - hour (12-hour clock) as a decimal number [01,12].
%j - day of the year as a decimal number [001,366].
%m - month as a decimal number [01,12].
%M - minute as a decimal number [00,59].
%L - milliseconds as a decimal number [000, 999].
%p - either AM or PM.
%S - second as a decimal number [00,61].
%U - week number of the year (Sunday as the first day of the week) as a decimal number [00,53].
%w - weekday as a decimal number [0(Sunday),6].
%W - week number of the year (Monday as the first day of the week) as a decimal number [00,53].
%x - date, as "%m/%d/%Y".
%X - time, as "%H:%M:%S".
%y - year without century as a decimal number [00,99].
%Y - year with century as a decimal number.
%Z - time zone offset, such as "-0700".
%% - a literal "%" character.
```

## Comments
Comments can be entered within a gantt chart, which will be ignored by the parser. Comments need to be on their own line and must be prefaced with `%%` (double percent signs). Any text after the start of the comment to the next newline will be treated as a comment, including any diagram syntax
```mmd
gantt
title A Gantt Diagram
%% this is a comment
dateFormat YYYY-MM-DD
section Section
A task :a1, 2014-01-01, 30d
Another task :after a1 , 20d
section Another
Task in sec :2014-01-12 , 12d
another task : 24d
```
## Styling
Styling of the a gantt diagram is done by defining a number of css classes. During rendering, these classes are extracted from the file located at src/themes/gantt.scss
### Classes used
Class | Description
--- | ---
grid.tick | Styling for the Grid Lines
grid.path | Styling for the Grid's borders
.taskText | Task Text Styling
.taskTextOutsideRight | Styling for Task Text that exceeds the activity bar towards the right.
.taskTextOutsideLeft | Styling for Task Text that exceeds the activity bar, towards the left.
todayMarker | Toggle and Styling for the "Today Marker"
### Sample stylesheet
```css
.grid .tick {
stroke: lightgrey;
opacity: 0.3;
shape-rendering: crispEdges;
}
.grid path {
stroke-width: 0;
}
#tag {
color: white;
background: #FA283D;
width: 150px;
position: absolute;
display: none;
padding:3px 6px;
margin-left: -80px;
font-size: 11px;
}
#tag:before {
border: solid transparent;
content: ' ';
height: 0;
left: 50%;
margin-left: -5px;
position: absolute;
width: 0;
border-width: 10px;
border-bottom-color: #FA283D;
top: -20px;
}
.taskText {
fill:white;
text-anchor:middle;
}
.taskTextOutsideRight {
fill:black;
text-anchor:start;
}
.taskTextOutsideLeft {
fill:black;
text-anchor:end;
}
```
## Today marker
You can style or hide the marker for the current date. To style it, add a value for the `todayMarker` key.
```
todayMarker stroke-width:5px,stroke:#0f0,opacity:0.5
```
To hide the marker, set `todayMarker` to `off`.
```
todayMarker off
```
## Configuration
It is possible to adjust the margins for rendering the gantt diagram.
This is done by defining the `ganttConfig` part of the configuration object.
How to use the CLI is described in the [mermaidCLI](mermaidCLI.html) page.
mermaid.ganttConfig can be set to a JSON string with config parameters or the corresponding object.
```javascript
mermaid.ganttConfig = {
titleTopMargin:25,
barHeight:20,
barGap:4,
topPadding:75,
sidePadding:75
}
```
### Possible configuration params:
Param | Description | Default value
--- | --- | ---
mirrorActor|Turns on/off the rendering of actors below the diagram as well as above it|false
bottomMarginAdj|Adjusts how far down the graph ended. Wide borders styles with css could generate unwanted clipping which is why this config param exists.|1
## Interaction
It is possible to bind a click event to a task. The click can lead to either a javascript callback or to a link which will be opened in the current browser tab. **Note**: This functionality is disabled when using `securityLevel='strict'` and enabled when using `securityLevel='loose'`.
```
click taskId call callback(arguments)
click taskId href URL
```
* taskId is the id of the task
* callback is the name of a javascript function defined on the page displaying the graph, the function will be called with the taskId as the parameter if no other arguments are specified.
Beginners tip, a full example using interactive links in an html context:
```html
<body>
<div class="mermaid">
gantt
dateFormat YYYY-MM-DD
section Clickable
Visit mermaidjs :active, cl1, 2014-01-07, 3d
Print arguments :cl2, after cl1, 3d
Print task :cl3, after cl2, 3d
click cl1 href "https://mermaidjs.github.io/"
click cl2 call printArguments("test1", "test2", test3)
click cl3 call printTask()
</div>
<script>
var printArguments = function(arg1, arg2, arg3) {
alert('printArguments called with arguments: ' + arg1 + ', ' + arg2 + ', ' + arg3);
}
var printTask = function(taskId) {
alert('taskId: ' + taskId);
}
var config = {
startOnLoad:true,
securityLevel:'loose',
};
mermaid.initialize(config);
</script>
</body>
```

Book description
</h1>
<div class="w-full mb-4">
<p class="text-black mb-4">
Mermaid lets you represent diagrams using text and code which simplifies the maintenance
of complex diagrams. This is a great option for developers as theyre more familiar with
code, rather than special tools for generating diagrams. Besides, diagrams in code
simplify maintenance and ensure that the code is supported by version control systems.
In some cases, Mermaid makes refactoring support for name changes possible while also
enabling team collaboration for review distribution and updates.
</p>
<p class="text-black mb-4">
Developers working with any system will be able to put their knowledge to work with this
practical guide to using Mermaid for documentation. The book is also a great reference
for looking up the syntax for specific diagrams when authoring diagrams.
</p>
<p class="text-black mb-4">
Youll start by getting up to speed with the importance of accurate and visual
documentation. Next, the book introduces Mermaid and establishes how to use it to create
effective documentation. By using different tools, editors, or a custom documentation
platform, youll also learn how to use Mermaid syntax for various diagrams. Later
chapters cover advanced configuration settings and theme options to manipulate your
diagram as per your needs.
</p>
<p class="text-black mb-4">
By the end of this Mermaid book, youll have become well-versed with the different types
of Mermaid diagrams and how they can be used in your workflows.

## splitting mermaid code from html
A more condensed html code can be achieved by embedding the mermaid code in its own .js file, which is referenced like so:
```
stuff stuff
</div>
</body>
</html>
```
The actual mermaid file could for example look like this:

# A Mermaid User-Guide for Beginners
Mermaid is composed of three parts: Deployment, Syntax and Configuration.
This section talks about the different ways to deploy Mermaid. Learning the [Syntax](./n00b-syntaxReference.md) would be of great help to the beginner.
> Generally the live editor is enough for most general uses of mermaid, and is a good place to start learning.
**Absolute beginners are advised to view the Video [Tutorials](./Tutorials.md) on the Live Editor, to gain a better understanding of mermaid.**
## Four ways of using mermaid:
1. Using the Mermaid Live Editor at [mermaid.live](https://mermaid.live).
2. Using [mermaid plugins](./integrations.md) with programs you are familiar with.
3. Calling the Mermaid Javascript API.
4. Deploying Mermaid as a dependency.
**Note: It is our recommendation that you review all approaches, and choose the one that is best for your project.**
> More in depth information can be found at [Usage](./usage.md).
## 1. Using the Live Editor
Available at [mermaid.live](https://mermaid.live)
![EditingProcess](./img/Editing-process.png)
In the `Code` section one can write or edit raw mermaid code, and instantly `Preview` the rendered result on the panel beside it.
The `Configuration` Section is for changing the appearance and behavior of mermaid diagrams. An easy introduction to mermaid configuration is found in the [Advanced usage](./n00b-advanced.md) section. A complete configuration reference cataloging the default values can be found on the [mermaidAPI](Setup.md) page.
![Code,Config and Preview](./img/Code-Preview-Config.png)
### Editing History
Your code will be autosaved every minute into the Timeline tab of History which shows the most recent 30 items.
You can manually save code by clicking the Save icon in the History section. It can also be accessed in the Saved tab. This is stored in the browser storage only.
### Saving a Diagram:
You may choose any of the methods below, to save it
**We recommend that you save your diagram code on top of any method you choose, in order to make edits and modifications further down the line.**
![Flowchart](./img/Live-Editor-Choices.png)
### Editing your diagrams
Editing is as easy as pasting your **Diagram code**, into the `code` section of the `Live Editor`.
### Loading from Gists
The Gist you create should have a code.mmd file and optionally a config.json. [Example](https://gist.github.com/sidharthv96/6268a23e673a533dcb198f241fd7012a)
To load a gist into the Editor, you can use https://mermaid-js.github.io/mermaid-live-editor/edit?gist=https://gist.github.com/sidharthv96/6268a23e673a533dcb198f241fd7012a
and to View, https://mermaid-js.github.io/mermaid-live-editor/view?gist=https://gist.github.com/sidharthv96/6268a23e673a533dcb198f241fd7012a
## 2. Using Mermaid Plugins:
You can generate mermaid diagrams from within popular applications using plug-ins. It can be done in the same way, you would use the Live Editor. Here's a list of [Mermaid Plugins](./integrations.md).
**This is covered in greater detail in the [Usage section](usage.md)**
## 3. Calling the Javascript API
This method can be used with any common web server like Apache, IIS, nginx, node express.
You will also need a text editing tool like Notepad++ to generate a .html file. It is then deployed by a web browser (such as Firefox, Chrome, Safari, but not Internet Explorer).
The API works by pulling rendering instructions from the source `mermaid.js` in order to render diagrams on the page.
### Requirements for the Mermaid API.
When writing the .html file, we give three instructions inside the html code to the web browser:
a. A reference for fetching the online mermaid renderer, through the `mermaid.js` or `mermaid.min.js`.
b. The mermaid code for the diagram we want to create.
c. The `mermaid.initialize()` call, which dictates the appearance of diagrams and also starts the rendering process .
**a. A reference to the external CDN in a `<script src>` tag, or a reference to mermaid.js as a separate file.:**
```html
<body>
<script src="https://cdn.jsdelivr.net/npm/mermaid/dist/mermaid.min.js"></script>
</body>
```
**b. The embedded mermaid diagram definition inside a `<div class="mermaid">`:**
```html
<body>
Here is a mermaid diagram:
<div class="mermaid">
graph TD
A[Client] --> B[Load Balancer]
B --> C[Server01]
B --> D[Server02]
</div>
</body>
```
**Notes**: Every Mermaid chart/graph/diagram definition, should have separate `<div>` tags.
**c. The `mermaid.initialize()` call.**
`mermaid.initialize()` call takes all the definitions contained in all the `<div class="mermaid">` tags that it finds in the html body and renders them into diagrams. Example:
```html
<body>
<script>
mermaid.initialize({ startOnLoad: true });
</script>
</body>
```
**Notes**:
Rendering in Mermaid is initalized by `mermaid.initialize()` call. You can place `mermaid.initialize()` inside `mermaid.min.js` for brevity. However, doing the opposite lets you control when it starts looking for `<div>`tags inside the web page with `mermaid.initialize()`. This is useful when you think that not all `<div>` tags may have loaded on the execution of `mermaid.min.js` file.
`startOnLoad` is one of the parameters that can be defined by `mermaid.initialize()`
| Parameter | Description | Type | Values |
| ----------- | --------------------------------- | ------- | ----------- |
| startOnLoad | Toggle for Rendering upon loading | Boolean | true, false |
### Working Examples
**Here is a full working example of the mermaidAPI being called through the CDN:**
```html
<html>
<body>
<script src="https://cdn.jsdelivr.net/npm/mermaid/dist/mermaid.min.js"></script>
<script>
mermaid.initialize({ startOnLoad: true });
</script>
Here is one mermaid diagram:
<div class="mermaid">
graph TD
A[Client] --> B[Load Balancer]
B --> C[Server1]
B --> D[Server2]
</div>
And here is another:
<div class="mermaid">
graph TD
A[Client] -->|tcp_123|
B(Load Balancer)
B -->|tcp_456| C[Server1]
B -->|tcp_456| D[Server2]
</div>
</body>
</html>
```
**Another Option:**
In this example mermaid.js is referenced in `src` as a separate JavaScript file, in an example Path.
```html
<html lang="en">
<head>
<meta charset="utf-8" />
</head>
<body>
<div class="mermaid">
graph LR
A --- B
B-->C[fa:fa-ban forbidden]
B-->D(fa:fa-spinner);
</div>
<div class="mermaid">
graph TD
A[Client] --> B[Load Balancer]
B --> C[Server1]
B --> D[Server2]
</div>
<script src="The\Path\In\Your\Package\mermaid.js"></script>
<script>
mermaid.initialize({ startOnLoad: true });
</script>
</body>
</html>
```
---
## 4. Adding Mermaid as a dependency.
1. install node v16, which would have npm
2. download yarn using npm by entering the command below:
npm install -g yarn
3. After yarn installs, enter the following command:
yarn add mermaid
4. To add Mermaid as a Dev Dependency
yarn add --dev mermaid
**Comments from Knut Sveidqvist, creator of mermaid:**
- In early versions of mermaid, the `<script src>` tag was invoked in the `<head>` part of the web page. Nowadays we can place it in the `<body>` as seen above. Older parts of the documentation frequently reflects the previous way which still works.

# Overview for Beginners
**Explaining with a Diagram**
A picture is worth a thousand words, a good diagram is undoubtedly worth more. They make understanding easier.
## Creating and Maintaining Diagrams
Anyone who has used Visio, or (God Forbid) Excel to make a Gantt Chart, knows how hard it is to create, edit and maintain good visualizations.
Diagrams/Charts are significant but also become obsolete/inaccurate very fast. This catch-22 hobbles the productivity of teams.
# Doc Rot in Diagrams
Doc-Rot kills diagrams as quickly as it does text, but it takes hours in a desktop application to produce a diagram.
Mermaid seeks to change using markdown-inspired syntax. The process is a quicker, less complicated, and more convenient way of going from concept to visualization.
It is a relatively straightforward solution to a significant hurdle with the software teams.
# Definition of Terms/ Dictionary
**Mermaid text definitions can be saved for later reuse and editing.**
>These are the Mermaid diagram definitions inside `<div>` tags, with the `class=mermaid`.
```html
<div class="mermaid">
graph TD
A[Client] --> B[Load Balancer]
B --> C[Server01]
B --> D[Server02]
</div>
```
**render**
>This is the core function of the Mermaid API. It reads all the `Mermaid Definitions` inside `div` tags and returns an SVG file, based on the definition.
**Nodes**
>These are the boxes that contain text or otherwise discrete pieces of each diagram, separated generally by arrows, except for Gantt Charts and User Journey Diagrams. They will be referred often in the instructions. Read for Diagram Specific [Syntax](./n00b-syntaxReference)
## Advantages of using Mermaid
- Ease to generate, modify and render diagrams when you make them.
- The number of integrations and plugins it has.
- You can add it to your or companies website.
- Diagrams can be created through comments like this in a script:
## The catch-22 of Diagrams and Charts:
**Diagramming and charting is a large waste of developer's time, but not having diagrams ruins productivity.**
Mermaid solves this by reducing the time and effort required to create diagrams and charts.
Because, the text base for the diagrams allows it to be updated easily. Also, it can be made part of production scripts (and other pieces of code). So less time is spent on documenting, as a separate task.
## Catching up with Development
Being based on markdown, Mermaid can be used, not only by accomplished front-end developers, but by most computer savvy people to render diagrams, at much faster speeds.
In fact one can pick up the syntax for it quite easily from the examples given and there are many tutorials available in the internet.
## Mermaid is for everyone.
Video [Tutorials](https://mermaid-js.github.io/mermaid/#/./Tutorials) are also available for the mermaid [live editor](https://mermaid-js.github.io/mermaid-live-editor/).
Alternatively you can use Mermaid [Plug-Ins](https://mermaid-js.github.io/mermaid/#/./integrations), with tools you already use, like Google Docs.

# Diagram Syntax
Mermaid's syntax is used to create diagrams. You'll find that it is not too tricky and can be learned in a day. The next sections dive deep into the syntax of each diagram type.
Syntax, together with Deployment and Configuration constitute the whole of Mermaid.
Diagram Examples can be found in the [Mermaid Live Editor](https://mermaid-js.github.io/mermaid-live-editor), it is also a great practice area.
## Syntax Structure
One would notice that all **Diagrams definitions begin** with a declaration of the **diagram type**, followed by the definitions of the diagram and its contents. This declaration notifies the parser which kind of diagram the code is supposed to generate.
**Example** : The code below is for an Entity Relationship Diagram, specified by the `erDiagram` declaration. What follows is the definition of the different `Entities` represented in it.
```mermaid-example
erDiagram
CUSTOMER }|..|{ DELIVERY-ADDRESS : has
CUSTOMER ||--o{ ORDER : places
CUSTOMER ||--o{ INVOICE : "liable for"
DELIVERY-ADDRESS ||--o{ ORDER : receives
INVOICE ||--|{ ORDER : covers
ORDER ||--|{ ORDER-ITEM : includes
PRODUCT-CATEGORY ||--|{ PRODUCT : contains
PRODUCT ||--o{ ORDER-ITEM : "ordered in"
```
The [Getting Started](./n00b-gettingStarted.md) section can also provide some practical examples of mermaid syntax.
## Diagram Breaking
One should **beware the use of some words or symbols** that can break diagrams. These words or symbols are few and often only affect specific types of diagrams. The table below will continuously be updated.
| Diagram Breakers | Reason |Solution|
| --- | --- |---|
| **Comments** | | |
|[`%%{``}%%`](https://github.com/mermaid-js/mermaid/issues/1968) | Similar to [Directives](./directives.md) confuses the renderer.|In comments using `%%`, avoid using "{}".|
| **Flow-Charts** | | |
|'end' | The word "End" can cause Flowcharts and Sequence diagrams to break | Wrap them in quotation marks to prevent breakage.|
| [Nodes inside Nodes](https://mermaid-js.github.io/mermaid/#/flowchart?id=special-characters-that-break-syntax)| Mermaid gets confused with nested shapes | wrap them in quotation marks to prevent breaking|
### Mermaid Live Editor
Now, that you've seen what you should not add to your diagrams, you can play around with them in the [Mermaid Live Editor](https://mermaid-js.github.io/mermaid-live-editor).
# Configuration
Configuration is the third part of Mermaid, after deployment and syntax. It deals with the different ways that Mermaid can be customized across different deployments.
If you are interested in altering and customizing your Mermaid Diagrams, you will find the methods and values available for [Configuration](./Setup.md) here. It includes themes.
This section will introduce the different methods of configuring the behaviors and appearances of Mermaid Diagrams.
The following are the most commonly used methods, and they are all tied to Mermaid [Deployment](./n00b-gettingStarted.md) methods.
### Configuration Section in the [Live Editor](https://mermaid-js.github.io/mermaid-live-editor).
Here you can edit certain values to change the behavior and appearance of the diagram.
### [The initialize() call](https://mermaid-js.github.io/mermaid/#/n00b-gettingStarted?id=_3-calling-the-javascript-api),
Used when Mermaid is called via an API, or through a `<script>` tag.
### [Directives](./directives.md),
Allows for the limited reconfiguration of a diagram just before it is rendered. It can alter the font style, color and other aesthetic aspects of the diagram. You can pass a directive alongside your definition inside `%%{ }%%`. It can be done either above or below your diagram definition.
### [Theme Manipulation](./theming.md):
An application of using Directives to change [Themes](./theming.md). `Theme` is a value within Mermaid's configuration that dictates the color scheme for diagrams.

# Adding a New Diagram/Chart 📊
### Step 1: Grammar & Parsing
#### Grammar
This would be to define a jison grammar for the new diagram type. That should start with a way to identify that the text in the mermaid tag is a diagram of that type. Create a new folder under diagrams for your new diagram type and a parser folder in it. This leads us to step 2.
For instance:
* the flowchart starts with the keyword graph.
* the sequence diagram starts with the keyword sequenceDiagram
#### Store data found during parsing
There are some jison specific sub steps here where the parser stores the data encountered when parsing the diagram, this data is later used by the renderer. You can during the parsing call a object provided to the parser by the user of the parser. This object can be called during parsing for storing data.
```jison
statement
: 'participant' actor { $$='actor'; }
| signal { $$='signal'; }
| note_statement { $$='note'; }
| 'title' message { yy.setTitle($2); }
;
```
In the extract of the grammar above, it is defined that a call to the setTitle method in the data object will be done when parsing and the title keyword is encountered.
```tip
Make sure that the `parseError` function for the parser is defined and calling `mermaidPAI.parseError`. This way a common way of detecting parse errors is provided for the end-user.
```
For more info look in the example diagram type:
The `yy` object has the following function:
```javascript
exports.parseError = function(err, hash){
mermaidAPI.parseError(err, hash)
};
```
when parsing the `yy` object is initialized as per below:
```javascript
var parser
parser = exampleParser.parser
parser.yy = db
```
### Step 2: Rendering
Write a renderer that given the data found during parsing renders the diagram. To look at an example look at sequendeRenderer.js rather then the flowchart renderer as this is a more generic example.
Place the renderer in the diagram folder.
### Step 3: Detection of the new diagram type
The second thing to do is to add the capability to detect the new new diagram to type to the detectType in utils.js. The detection should return a key for the new diagram type.
### Step 4: The final piece - triggering the rendering
At this point when mermaid is trying to render the diagram, it will detect it as being of the new type but there will be no match when trying to render the diagram. To fix this add a new case in the switch statement in main.js:init this should match the diagram type returned from step #2. The code in this new case statement should call the renderer for the diagram type with the data found by the parser as an argument.
## Usage of the parser as a separate module
### Setup
```javascript
var graph = require('./graphDb')
var flow = require('./parser/flow')
flow.parser.yy = graph
```
### Parsing
```javascript
flow.parser.parse(text)
```
### Data extraction
```javascript
graph.getDirection()
graph.getVertices()
graph.getEdges()
```
The parser is also exposed in the mermaid api by calling:
```javascript
var parser = mermaid.getParser()
```
Note that the parse needs a graph object to store the data as per:
```javascript
flow.parser.yy = graph
```
Look at `graphDb.js` for more details on that object.

# Pie chart diagrams
> A pie chart (or a circle chart) is a circular statistical graphic, which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice (and consequently its central angle and area), is proportional to the quantity it represents. While it is named for its resemblance to a pie which has been sliced, there are variations on the way it can be presented. The earliest known pie chart is generally credited to William Playfair's Statistical Breviary of 1801
-Wikipedia
Mermaid can render Pie Chart diagrams.
```mermaid-example
pie title Pets adopted by volunteers
"Dogs" : 386
"Cats" : 85
"Rats" : 15
```
## Syntax
Drawing a pie chart is really simple in mermaid.
- Start with `pie` keyword to begin the diagram
- Followed by `title` keyword and its value in string to give a title to the pie-chart. This is ***OPTIONAL***
- Followed by dataSet
- `label` for a section in the pie diagram within `" "` quotes.
- Followed by `:` colon as separator
- Followed by `positive numeric value` (supported upto two decimal places)
[pie]
[title] [titlevalue] (OPTIONAL)
"[datakey1]" : [dataValue1]
"[datakey2]" : [dataValue2]
"[datakey3]" : [dataValue3]
.
.
## Example
```mermaid-example
pie
title Key elements in Product X
"Calcium" : 42.96
"Potassium" : 50.05
"Magnesium" : 10.01
"Iron" : 5
```

# Requirement Diagram
**Edit this Page** [![N|Solid](img/GitHub-Mark-32px.png)](https://github.com/mermaid-js/mermaid/blob/develop/docs/requirementDiagram.md)
> A Requirement diagram provides a visualization for requirements and their connections, to each other and other documented elements. The modeling specs follow those defined by SysML v1.6.
Rendering requirements is straightforward.
```mermaid-example
requirementDiagram
requirement test_req {
id: 1
text: the test text.
risk: high
verifymethod: test
}
element test_entity {
type: simulation
}
test_entity - satisfies -> test_req
```
## Syntax
There are three types of components to a requirement diagram: requirement, element, and relationship.
The grammar for defining each is defined below. Words denoted in angle brackets, such as ```<word>```, are enumerated keywords that have options elaborated in a table. ```user_defined_...``` is use in any place where user input is expected.
An important note on user text: all input can be surrounded in quotes or not. For example, both ```Id: "here is an example"``` and ```Id: here is an example``` are both valid. However, users must be careful with unquoted input. The parser will fail if another keyword is detected.
### Requirement
A requirement definition contains a requirement type, name, id, text, risk, and verification method. The syntax follows:
```
<type> user_defined_name {
id: user_defined_id
text: user_defined text
risk: <risk>
verifymethod: <method>
}
```
Type, risk, and method are enumerations defined in SysML.
| Keyword | Options |
|---|---|
| Type | requirement, functionalRequirement, interfaceRequirement, performanceRequirement, physicalRequirement, designConstraint |
| Risk | Low, Medium, High |
| VerificationMethod | Analysis, Inspection, Test, Demonstration |
### Element
An element definition contains an element name, type, and document reference. These three are all user defined. The element feature is intended to be lightweight but allow requirements to be connected to portions of other documents.
```
element user_defined_name {
type: user_defined_type
docref: user_defined_ref
}
```
### Relationship
Relationships are comprised of a source node, destination node, and relationship type.
Each follows the definition format of
```
{name of source} - <type> -> {name of destination}
```
or
```
{name of destination} <- <type> - {name of source}
```
"name of source" and "name of destination" should be names of requirement or element nodes defined elsewhere.
A relationship type can be one of contains, copies, derives, satisfies, verifies, refines, or traces.
Each relationship is labeled in the diagram.
## Larger Example
This example uses all features of the diagram.
```mermaid-example
requirementDiagram
requirement test_req {
id: 1
text: the test text.
risk: high
verifymethod: test
}
functionalRequirement test_req2 {
id: 1.1
text: the second test text.
risk: low
verifymethod: inspection
}
performanceRequirement test_req3 {
id: 1.2
text: the third test text.
risk: medium
verifymethod: demonstration
}
interfaceRequirement test_req4 {
id: 1.2.1
text: the fourth test text.
risk: medium
verifymethod: analysis
}
physicalRequirement test_req5 {
id: 1.2.2
text: the fifth test text.
risk: medium
verifymethod: analysis
}
designConstraint test_req6 {
id: 1.2.3
text: the sixth test text.
risk: medium
verifymethod: analysis
}
element test_entity {
type: simulation
}
element test_entity2 {
type: word doc
docRef: reqs/test_entity
}
element test_entity3 {
type: "test suite"
docRef: github.com/all_the_tests
}
test_entity - satisfies -> test_req2
test_req - traces -> test_req2
test_req - contains -> test_req3
test_req3 - contains -> test_req4
test_req4 - derives -> test_req5
test_req5 - refines -> test_req6
test_entity3 - verifies -> test_req5
test_req <- copies - test_entity2
```

# Security
The Mermaid team takes the security of Mermaid and the applications that use Mermaid seriously. This page describes how to report any vulnerabilities you may find, and lists best practices to minimize the risk of introducing a vulnerability.
## Reporting vulnerabilities
To report a vulnerability, please e-mail security@mermaid.live with a description of the issue, the steps you took to create the issue, affected versions, and if known, mitigations for the issue.
We aim to reply within three working days, probably much sooner.
You should expect a close collaboration as we work to resolve the issue you have reported. Please reach out to security@mermaid.live again if you do not receive prompt attention and regular updates.
You may also reach out to the team via our public Slack chat channels; however, please make sure to e-mail security@mernaid.live when reporting an issue, and avoid revealing information about vulnerabilities in public as that could that could put users at risk.
## Best practices
Keep current with the latest Mermaid releases. We regularly update Mermaid, and these updates may fix security defects discovered in previous versions. Check the Mermaid release notes for security-related updates.
Keep your applications dependencies up to date. Make sure you upgrade your package dependencies to keep the dependencies up to date. Avoid pinning to specific versions for your dependencies and, if you do, make sure you check periodically to see if your dependencies have had security updates, and update the pin accordingly.

# Sequence diagrams
**Edit this Page** [![N|Solid](img/GitHub-Mark-32px.png)](https://github.com/mermaid-js/mermaid/blob/develop/docs/sequenceDiagram.md)
> A Sequence diagram is an interaction diagram that shows how processes operate with one another and in what order.
Mermaid can render sequence diagrams.
```mermaid-example
sequenceDiagram
Alice->>John: Hello John, how are you?
John-->>Alice: Great!
Alice-)John: See you later!
```
```note
A note on nodes, the word "end" could potentially break the diagram, due to the way that the mermaid language is scripted.
If unavoidable, one must use parentheses(), quotation marks "", or brackets {},[], to enclose the word "end". i.e : (end), [end], {end}.
```
## Syntax
### Participants
The participants can be defined implicitly as in the first example on this page. The participants or actors are
rendered in order of appearance in the diagram source text. Sometimes you might want to show the participants in a
different order than how they appear in the first message. It is possible to specify the actor's order of
appearance by doing the following:
```mermaid-example
sequenceDiagram
participant Alice
participant Bob
Alice->>Bob: Hi Bob
Bob->>Alice: Hi Alice
```
### Actors
If you specifically want to use the actor symbol instead of a rectangle with text you can do so by using actor statements as per below.
```mermaid-example
sequenceDiagram
actor Alice
actor Bob
Alice->>Bob: Hi Bob
Bob->>Alice: Hi Alice
```
### Aliases
The actor can have a convenient identifier and a descriptive label.
```mermaid-example
sequenceDiagram
participant A as Alice
participant J as John
A->>J: Hello John, how are you?
J->>A: Great!
```
## Messages
Messages can be of two displayed either solid or with a dotted line.
```
[Actor][Arrow][Actor]:Message text
```
There are six types of arrows currently supported:
| Type | Description |
| ---- | ------------------------------------------- |
| -> | Solid line without arrow |
| --> | Dotted line without arrow |
| ->> | Solid line with arrowhead |
| -->> | Dotted line with arrowhead |
| -x | Solid line with a cross at the end |
| --x | Dotted line with a cross at the end. |
| -) | Solid line with an open arrow at the end (async) |
| --) | Dotted line with a open arrow at the end (async) |
## Activations
It is possible to activate and deactivate an actor. (de)activation can be dedicated declarations:
```mermaid-example
sequenceDiagram
Alice->>John: Hello John, how are you?
activate John
John-->>Alice: Great!
deactivate John
```
There is also a shortcut notation by appending `+`/`-` suffix to the message arrow:
```mermaid-example
sequenceDiagram
Alice->>+John: Hello John, how are you?
John-->>-Alice: Great!
```
Activations can be stacked for same actor:
```mermaid-example
sequenceDiagram
Alice->>+John: Hello John, how are you?
Alice->>+John: John, can you hear me?
John-->>-Alice: Hi Alice, I can hear you!
John-->>-Alice: I feel great!
```
## Notes
It is possible to add notes to a sequence diagram. This is done by the notation
Note [ right of | left of | over ] [Actor]: Text in note content
See the example below:
```mermaid-example
sequenceDiagram
participant John
Note right of John: Text in note
```
It is also possible to create notes spanning two participants:
```mermaid-example
sequenceDiagram
Alice->John: Hello John, how are you?
Note over Alice,John: A typical interaction
```
## Loops
It is possible to express loops in a sequence diagram. This is done by the notation
```
loop Loop text
... statements ...
end
```
See the example below:
```mermaid-example
sequenceDiagram
Alice->John: Hello John, how are you?
loop Every minute
John-->Alice: Great!
end
```
## Alt
It is possible to express alternative paths in a sequence diagram. This is done by the notation
```
alt Describing text
... statements ...
else
... statements ...
end
```
or if there is sequence that is optional (if without else).
```
opt Describing text
... statements ...
end
```
See the example below:
```mermaid-example
sequenceDiagram
Alice->>Bob: Hello Bob, how are you?
alt is sick
Bob->>Alice: Not so good :(
else is well
Bob->>Alice: Feeling fresh like a daisy
end
opt Extra response
Bob->>Alice: Thanks for asking
end
```
## Parallel
It is possible to show actions that are happening in parallel.
This is done by the notation
```
par [Action 1]
... statements ...
and [Action 2]
... statements ...
and [Action N]
... statements ...
end
```
See the example below:
```mermaid-example
sequenceDiagram
par Alice to Bob
Alice->>Bob: Hello guys!
and Alice to John
Alice->>John: Hello guys!
end
Bob-->>Alice: Hi Alice!
John-->>Alice: Hi Alice!
```
It is also possible to nest parallel blocks.
```mermaid-example
sequenceDiagram
par Alice to Bob
Alice->>Bob: Go help John
and Alice to John
Alice->>John: I want this done today
par John to Charlie
John->>Charlie: Can we do this today?
and John to Diana
John->>Diana: Can you help us today?
end
end
```
## Background Highlighting
It is possible to highlight flows by providing colored background rects. This is done by the notation
The colors are defined using rgb and rgba syntax.
```
rect rgb(0, 255, 0)
... content ...
end
```
```
rect rgba(0, 0, 255, .1)
... content ...
end
```
See the examples below:
```mermaid-example
sequenceDiagram
participant Alice
participant John
rect rgb(191, 223, 255)
note right of Alice: Alice calls John.
Alice->>+John: Hello John, how are you?
rect rgb(200, 150, 255)
Alice->>+John: John, can you hear me?
John-->>-Alice: Hi Alice, I can hear you!
end
John-->>-Alice: I feel great!
end
Alice ->>+ John: Did you want to go to the game tonight?
John -->>- Alice: Yeah! See you there.
```
## Comments
Comments can be entered within a sequence diagram, which will be ignored by the parser. Comments need to be on their own line, and must be prefaced with `%%` (double percent signs). Any text after the start of the comment to the next newline will be treated as a comment, including any diagram syntax
```mmd
sequenceDiagram
Alice->>John: Hello John, how are you?
%% this is a comment
John-->>Alice: Great!
```
## Entity codes to escape characters
It is possible to escape characters using the syntax exemplified here.
```mermaid-example
sequenceDiagram
A->>B: I #9829; you!
B->>A: I #9829; you #infin; times more!
```
Numbers given are base 10, so `#` can be encoded as `#35;`. It is also supported to use HTML character names.
Because semicolons can be used instead of line breaks to define the markup, you need to use `#59;` to include a semicolon in message text.
## sequenceNumbers
It is possible to get a sequence number attached to each arrow in a sequence diagram. This can be configured when adding mermaid to the website as shown below:
```html
<script>
mermaid.initialize({
sequence: { showSequenceNumbers: true },
});
</script>
```
It can also be be turned on via the diagram code as in the diagram:
```mermaid-example
sequenceDiagram
autonumber
Alice->>John: Hello John, how are you?
loop Healthcheck
John->>John: Fight against hypochondria
end
Note right of John: Rational thoughts!
John-->>Alice: Great!
John->>Bob: How about you?
Bob-->>John: Jolly good!
```
## Actor Menus
Actors can have popup-menus containing individualized links to external pages. For example, if an actor represented a web service, useful links might include a link to the service health dashboard, repo containing the code for the service, or a wiki page describing the service.
This can be configured by adding one or more link lines with the format:
```
link <actor>: <link-label> @ <link-url>
```
```mmd
sequenceDiagram
participant Alice
participant John
link Alice: Dashboard @ https://dashboard.contoso.com/alice
link Alice: Wiki @ https://wiki.contoso.com/alice
link John: Dashboard @ https://dashboard.contoso.com/john
link John: Wiki @ https://wiki.contoso.com/john
Alice->>John: Hello John, how are you?
John-->>Alice: Great!
Alice-)John: See you later!
```
#### Advanced Menu Syntax
There is an advanced syntax that relies on JSON formatting. If you are comfortable with JSON format, then this exists as well.
This can be configured by adding the links lines with the format:
```
links <actor>: <json-formatted link-name link-url pairs>
```
An example is below:
```mmd
sequenceDiagram
participant Alice
participant John
links Alice: {"Dashboard": "https://dashboard.contoso.com/alice", "Wiki": "https://wiki.contoso.com/alice"}
links John: {"Dashboard": "https://dashboard.contoso.com/john", "Wiki": "https://wiki.contoso.com/john"}
Alice->>John: Hello John, how are you?
John-->>Alice: Great!
Alice-)John: See you later!
```
## Styling
Styling of a sequence diagram is done by defining a number of css classes. During rendering these classes are extracted from the file located at src/themes/sequence.scss
### Classes used
| Class | Description |
| ------------ | ----------------------------------------------------------- |
| actor | Style for the actor box at the top of the diagram. |
| text.actor | Styles for text in the actor box at the top of the diagram. |
| actor-line | The vertical line for an actor. |
| messageLine0 | Styles for the solid message line. |
| messageLine1 | Styles for the dotted message line. |
| messageText | Defines styles for the text on the message arrows. |
| labelBox | Defines styles label to left in a loop. |
| labelText | Styles for the text in label for loops. |
| loopText | Styles for the text in the loop box. |
| loopLine | Defines styles for the lines in the loop box. |
| note | Styles for the note box. |
| noteText | Styles for the text on in the note boxes. |
### Sample stylesheet
```css
body {
background: white;
}
.actor {
stroke: #ccccff;
fill: #ececff;
}
text.actor {
fill: black;
stroke: none;
font-family: Helvetica;
}
.actor-line {
stroke: grey;
}
.messageLine0 {
stroke-width: 1.5;
stroke-dasharray: '2 2';
marker-end: 'url(#arrowhead)';
stroke: black;
}
.messageLine1 {
stroke-width: 1.5;
stroke-dasharray: '2 2';
stroke: black;
}
#arrowhead {
fill: black;
}
.messageText {
fill: black;
stroke: none;
font-family: 'trebuchet ms', verdana, arial;
font-size: 14px;
}
.labelBox {
stroke: #ccccff;
fill: #ececff;
}
.labelText {
fill: black;
stroke: none;
font-family: 'trebuchet ms', verdana, arial;
}
.loopText {
fill: black;
stroke: none;
font-family: 'trebuchet ms', verdana, arial;
}
.loopLine {
stroke-width: 2;
stroke-dasharray: '2 2';
marker-end: 'url(#arrowhead)';
stroke: #ccccff;
}
.note {
stroke: #decc93;
fill: #fff5ad;
}
.noteText {
fill: black;
stroke: none;
font-family: 'trebuchet ms', verdana, arial;
font-size: 14px;
}
```
## Configuration
Is it possible to adjust the margins for rendering the sequence diagram.
This is done by defining `mermaid.sequenceConfig` or by the CLI to use a json file with the configuration.
How to use the CLI is described in the [mermaidCLI](mermaidCLI) page.
`mermaid.sequenceConfig` can be set to a JSON string with config parameters or the corresponding object.
```javascript
mermaid.sequenceConfig = {
diagramMarginX: 50,
diagramMarginY: 10,
boxTextMargin: 5,
noteMargin: 10,
messageMargin: 35,
mirrorActors: true
};
```
### Possible configuration parameters:
| Parameter | Description | Default value |
| ----------------- | ------------------------------------------------------------------------------------------------------------------------------------------ | ------------------------------ |
| mirrorActors | Turns on/off the rendering of actors below the diagram as well as above it | false |
| bottomMarginAdj | Adjusts how far down the graph ended. Wide borders styles with css could generate unwanted clipping which is why this config param exists. | 1 |
| actorFontSize | Sets the font size for the actor's description | 14 |
| actorFontFamily | Sets the font family for the actor's description | "Open-Sans", "sans-serif" |
| actorFontWeight | Sets the font weight for the actor's description | "Open-Sans", "sans-serif" |
| noteFontSize | Sets the font size for actor-attached notes | 14 |
| noteFontFamily | Sets the font family for actor-attached notes | "trebuchet ms", verdana, arial |
| noteFontWeight | Sets the font weight for actor-attached notes | "trebuchet ms", verdana, arial |
| noteAlign | Sets the text alignment for text in actor-attached notes | center |
| messageFontSize | Sets the font size for actor<->actor messages | 16 |
| messageFontFamily | Sets the font family for actor<->actor messages | "trebuchet ms", verdana, arial |
| messageFontWeight | Sets the font weight for actor<->actor messages | "trebuchet ms", verdana, arial |

# State diagrams
> "A state diagram is a type of diagram used in computer science and related fields to describe the behavior of systems. State diagrams require that the system described is composed of a finite number of states; sometimes, this is indeed the case, while at other times this is a reasonable abstraction." Wikipedia
Mermaid can render state diagrams. The syntax tries to be compliant with the syntax used in plantUml as this will make it easier for users to share diagrams between mermaid and plantUml.
```mermaid-example
stateDiagram-v2
[*] --> Still
Still --> [*]
Still --> Moving
Moving --> Still
Moving --> Crash
Crash --> [*]
```
Older renderer:
```mermaid-example
stateDiagram
[*] --> Still
Still --> [*]
Still --> Moving
Moving --> Still
Moving --> Crash
Crash --> [*]
```
In state diagrams systems are described in terms of its states and how the systems state can change to another state via a transitions. The example diagram above shows three states **Still**, **Moving** and **Crash**. You start in the state of Still. From Still you can change the state to Moving. In Moving you can change the state either back to Still or to Crash. There is no transition from Still to Crash.
## States
A state can be declared in multiple ways. The simplest way is to define a state id as a description.
```mermaid-example
stateDiagram-v2
s1
```
Another way is by using the state keyword with a description as per below:
```mermaid-example
stateDiagram-v2
state "This is a state description" as s2
```
Another way to define a state with a description is to define the state id followed by a colon and the description:
```mermaid-example
stateDiagram-v2
s2 : This is a state description
```
## Transitions
Transitions are path/edges when one state passes into another. This is represented using text arrow, "\-\-\>".
When you define a transition between two states and the states are not already defined the undefined states are defined with the id from the transition. You can later add descriptions to states defined this way.
```mermaid-example
stateDiagram-v2
s1 --> s2
```
It is possible to add text to a transition. To describe what it represents.
```mermaid-example
stateDiagram-v2
s1 --> s2: A transition
```
## Start and End
There are two special states indicating the start and stop of the diagram. These are written with the [\*] syntax and the direction of the transition to it defines it either as a start or a stop state.
```mermaid-example
stateDiagram-v2
[*] --> s1
s1 --> [*]
```
## Composite states
In a real world use of state diagrams you often end up with diagrams that are multi-dimensional as one state can
have several internal states. These are called composite states in this terminology.
In order to define a composite state you need to use the state keyword followed by an id and the body of the composite state between \{\}. See the example below:
```mermaid-example
stateDiagram-v2
[*] --> First
state First {
[*] --> second
second --> [*]
}
```
You can do this in several layers:
```mermaid-example
stateDiagram-v2
[*] --> First
state First {
[*] --> Second
state Second {
[*] --> second
second --> Third
state Third {
[*] --> third
third --> [*]
}
}
}
```
You can also define transitions also between composite states:
```mermaid-example
stateDiagram-v2
[*] --> First
First --> Second
First --> Third
state First {
[*] --> fir
fir --> [*]
}
state Second {
[*] --> sec
sec --> [*]
}
state Third {
[*] --> thi
thi --> [*]
}
```
*You can not define transitions between internal states belonging to different composite states*
## Choice
Sometimes you need to model a choice between two or more paths, you can do so using &lt;&lt;choice&gt;&gt;.
```mermaid-example
stateDiagram-v2
state if_state <<choice>>
[*] --> IsPositive
IsPositive --> if_state
if_state --> False: if n < 0
if_state --> True : if n >= 0
```
## Forks
It is possible to specify a fork in the diagram using &lt;&lt;fork&gt;&gt; &lt;&lt;join&gt;&gt;.
```mermaid-example
stateDiagram-v2
state fork_state <<fork>>
[*] --> fork_state
fork_state --> State2
fork_state --> State3
state join_state <<join>>
State2 --> join_state
State3 --> join_state
join_state --> State4
State4 --> [*]
```
## Notes
Sometimes nothing says it better then a Post-it note. That is also the case in state diagrams.
Here you can choose to put the note to the *right of* or to the *left of* a node.
```mermaid-example
stateDiagram-v2
State1: The state with a note
note right of State1
Important information! You can write
notes.
end note
State1 --> State2
note left of State2 : This is the note to the left.
```
## Concurrency
As in plantUml you can specify concurrency using the -- symbol.
```mermaid-example
stateDiagram-v2
[*] --> Active
state Active {
[*] --> NumLockOff
NumLockOff --> NumLockOn : EvNumLockPressed
NumLockOn --> NumLockOff : EvNumLockPressed
--
[*] --> CapsLockOff
CapsLockOff --> CapsLockOn : EvCapsLockPressed
CapsLockOn --> CapsLockOff : EvCapsLockPressed
--
[*] --> ScrollLockOff
ScrollLockOff --> ScrollLockOn : EvScrollLockPressed
ScrollLockOn --> ScrollLockOff : EvScrollLockPressed
}
```
## Setting the direction of the diagram
With state diagrams you can use the direction statement to set the direction which the diagram will render like in this example.
```mermaid-example
stateDiagram
direction LR
[*] --> A
A --> B
B --> C
state B {
direction LR
a --> b
}
B --> D
```
## Comments
Comments can be entered within a state diagram chart, which will be ignored by the parser. Comments need to be on their own line, and must be prefaced with `%%` (double percent signs). Any text after the start of the comment to the next newline will be treated as a comment, including any diagram syntax
```mmd
stateDiagram-v2
[*] --> Still
Still --> [*]
%% this is a comment
Still --> Moving
Moving --> Still %% another comment
Moving --> Crash
Crash --> [*]
```

# Theme Configuration
**Edit this Page** [![N|Solid](img/GitHub-Mark-32px.png)](https://github.com/mermaid-js/mermaid/blob/develop/docs/theming.md)
With Version 8.7.0 Mermaid comes out with a system for dynamic and integrated configuration of the diagram themes. The objective of this is to increase the customizability of mermaid and the ease of Styling, with the customization of themes through the `%%init%%` directive and `initialize` calls.
Themes follow and build upon the Levels of Configuration and employ `directives` to modify and create custom configurations, as they were introduced in Version [8.6.0](./8.6.0_docs.md).
**These Theming Configurations, similar to directives, will also be made applicable in the Live-Editor, to maximize customizability.
## Site-wide Themes
Site-wide themes are still declared via `initialize` by site owners.
Example of `Initalize` call setting `theme` to `base`:
```javascript
mermaidAPI.initialize({
'securityLevel': 'loose', 'theme': 'base'
});
```
**Notes**: Only site owners can use the `mermaidAPI.initialize` call, to set values. Site-Users will have to use `%%init%%` to modify or create the theme for their diagrams.
## Themes at the Local or Current Level
When Generating a diagram using on a webpage that supports mermaid. It is also possible to override site-wide theme settings locally, for a specific diagram, using directives, as long as it is not prohibited by the `secure` array.
```mmd
%%{init: {'theme':'base'}}%%
graph TD
a --> b
```
Here is an example of how `%%init%%` can set the theme to 'base', this assumes that `themeVariables` are set to default:
```mermaid-example
%%{init: {'theme':'base'}}%%
graph TD
A[Christmas] -->|Get money| B(Go shopping)
B --> C{Let me think}
B --> G[/Another/]
C ==>|One| D[Laptop]
C -->|Two| E[iPhone]
C -->|Three| F[fa:fa-car Car]
subgraph section
C
D
E
F
G
end
```
# Making a Custom Theme with `themeVariables`
The easiest way to make a custom theme is to start with the base theme, and just modify theme variables through `themeVariables`, via `%%init%%`.
| Parameter | Description | Type | Required | Objects contained |
| -------------- | ------------------------------------------------------------------ | ----- | -------- | ---------------------------------- |
| themeVariables | Array containing objects, modifiable with the `%%init%%` directive | Array | Required | primaryColor, lineColor, textColor |
## Here is an example of overriding `primaryColor` through `themeVariables` and giving everything a different look, using `%%init%%`.
```mermaid-example
%%{init: {'theme': 'base', 'themeVariables': { 'primaryColor': '#ff0000'}}}%%
graph TD
A[Christmas] -->|Get money| B(Go shopping)
B --> C{Let me think}
B --> G[/Another/]
C ==>|One| D[Laptop]
C -->|Two| E[iPhone]
C -->|Three| F[fa:fa-car Car]
subgraph section
C
D
E
F
G
end
```
**Notes:**
Leaving it empty will set all variable values to default.
## Color and Color Calculation:
Color definitions have certain interactions in mermaid, this is in order to ensure visibility for diagrams. mermaid will adjust some variables automatically, when colors are changed in order to compensate and maintain readability.
**The Default Value Column** to the right of the Variable column will denote the Variable paired/associated with the Variable on the left and the nature of this pairing or association. If it for instance says primaryColor it means that it gets primaryColor as default value. If it says "based on primaryColor" it means that it is calculated/ derived from primaryColor. This calculation can be primary color inversion, a change of hue, darkening or lightening by 10%, etc.
You can create your own themes, by changing any of the given variables below. If you are using a dark background, set dark mode to true to adjust the colors. It is possible to override the calculations using the variable names below, with `%%init%%` if you wish to style it differently.
## Theme Variables Reference Table
```note
Variables that are unique to some diagrams can be affected by changes in Theme Variables
```

# Here is an example of overriding `primaryColor` and giving everything a different look, using `%%init%%`.
```mermaid-example
%%{init: {'theme': 'base', 'themeVariables': { 'primaryColor': '#ff0000'}}}%%
graph TD
A[Christmas] -->|Get money| B(Go shopping)
B --> C{Let me think}
B --> G[/Another/]
C ==>|One| D[Laptop]
C -->|Two| E[iPhone]
C -->|Three| F[fa:fa-car Car]
subgraph section
C
D
E
F
G
end
```
**This got a bit too dark and bit too colorful. With some easy steps this can be fixed:
* Make the primary color a little lighter
* set the tertiary color to a reddish shade as well
* make the edge label background differ from the subgraph by setting the edgeLabelBackground
```mermaid-example
%%{init: {'theme': 'base', 'themeVariables': { 'primaryColor': '#ffcccc', 'edgeLabelBackground':'#ffffee', 'tertiaryColor': '#fff0f0'}}}%%
graph TD
A[Christmas] -->|Get money| B(Go shopping)
B --> C{Let me think}
B --> G[/Another/]
C ==>|One| D[Laptop]
C -->|Two| E[iPhone]
C -->|Three| F[fa:fa-car Car]
subgraph section
C
D
E
F
G
end
```
The Theming Engine does not admit color codes and will only accept proper color values. Color Names is not supported so for instance, the color value 'red' will not work, but '#ff0000' will work.
# Common theming activities
## How to change the color of the arrows
# Examples:
When adjusting a theme it might be helpful to look at how your preferred theme goes with the diagrams, to evaluate whether everything is visible and looks good.
In the following examples, the directive `init` is used, with the `theme` being declared as `base`. For more information on using directives, read the documentation for [Version 8.6.0](/8.6.0_docs.md)

# Upgrading
Some of the interfaces has been upgraded.
## From version 0.4.0 to 0.5.0
### Initialization
`mermaid_config` is no longer used. Instead a call to mermaid initialize is done as in the example below:
#### version 0.4.0
```javascript
mermaid_config = {
startOnLoad: true
}
```
#### version 0.5.0
```javascript
mermaid.initialize({
startOnLoad: true
})

# Usage
**Edit this Page** [![N|Solid](img/GitHub-Mark-32px.png)](https://github.com/mermaid-js/mermaid/blob/develop/docs/usage.md)
Mermaid is a Javascript tool that makes use of a markdown based syntax to render customizable diagrams, charts and visualizations.
Diagrams can be re-rendered/modified by modifying their descriptions.
### CDN
[https://unpkg.com/mermaid/](https://unpkg.com/mermaid/)
Please note that you can switch versions through the dropdown box at the top right.
## Using mermaid
For the majority of users, Using the [Live Editor](https://mermaid-js.github.io/mermaid-live-editor/) would be sufficient, however you may also opt to deploy mermaid as a dependency or using the [Mermaid API](./Setup.md).
We have compiled some Video [Tutorials](./Tutorials.md) on how to use the mermaid Live Editor.
**Installing and Hosting Mermaid on a Webpage**
**Using the npm package**
```
1.You will need to install node v16, which would have npm.
2. download yarn using npm.
3. enter the following command:
yarn add mermaid
4. At this point, you can add mermaid as a dev dependency using this command:
yarn add --dev mermaid
5. Alternatively, you can also deploy mermaid using the script tag in an HTML file with mermaid diagram descriptions.
as is shown in the example below
```
**Hosting mermaid on a web page.**
>Note:This topic explored in greater depth in the [User Guide for Beginners](./n00b-gettingStarted.md)
The easiest way to integrate mermaid on a web page requires three elements:
1. Inclusion of the mermaid address in the html page using a `script` tag, in the `src` section.Example:
```html
<script src="https://cdn.jsdelivr.net/npm/mermaid/dist/mermaid.min.js"></script>
```
2. The `mermaidAPI` call, in a separate `script` tag. Example:
```html
<script>mermaid.initialize({startOnLoad:true});</script>
```
3. A graph definition, inside `<div>` tags labeled `class=mermaid`. Example:
```html
<div class="mermaid">
graph LR
A --- B
B-->C[fa:fa-ban forbidden]
B-->D(fa:fa-spinner);
</div>
```
**Following these directions, mermaid starts at page load and (when the page has loaded) it will
locate the graph definitions inside the `div` tags with `class="mermaid"` and return diagrams in SVG form, following given definitions.**
## Simple full example:
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
</head>
<body>
<div class="mermaid">
graph LR
A --- B
B-->C[fa:fa-ban forbidden]
B-->D(fa:fa-spinner);
</div>
<script src="https://cdn.jsdelivr.net/npm/mermaid/dist/mermaid.min.js"></script>
<script>mermaid.initialize({startOnLoad:true});</script>
</body>
</html>
```
## Notes:
An id attribute is also added to mermaid tags without one.
Mermaid can load multiple diagrams, in the same page.
> Try it out, save this code as HTML and load it using any browser.(Except Internet Explorer, please don't use Internet Explorer.)
## Enabling Click Event and Tags in Nodes
A `securityLevel` configuration has to first be cleared, `securityLevel` sets the level of trust for the parsed diagrams and limits click functionality. This was introduce in version 8.2 as a security improvement, aimed at preventing malicious use.
**It is the site owner's responsibility to discriminate between trustworthy and untrustworthy user-bases and we encourage the use of discretion.**
## securityLevel
| Parameter | Description | Type | Required | Values |
| ------------- | --------------------------------- | ------ | -------- | ------------------------- |
| securityLevel | Level of trust for parsed diagram | String | Required | Strict, Loose, antiscript |
Values:
- **strict**: (**default**) tags in text are encoded, click functionality is disabled
- **loose**: tags in text are allowed, click functionality is enabled
- **antiscript**: html tags in text are allowed, (only script element is removed), click functionality is enabled
```note
This changes the default behaviour of mermaid so that after upgrade to 8.2,unless the `securityLevel` is not changed, tags in flowcharts are encoded as tags and clicking is disabled.
```
**If you are taking responsibility for the diagram source security you can set the `securityLevel` to a value of your choosing . This allows clicks and tags are allowed.**
**To change `securityLevel`, you have to call `mermaidAPI.initialize`:**
```javascript
mermaidAPI.initialize({
securityLevel: 'loose'
});
```
### Labels out of bounds
If you use dynamically loaded fonts that are loaded through CSS, such as Google fonts, mermaid should wait for the
whole page to load (dom + assets, particularly the fonts file).
```javascript
$(document).load(function() {
mermaid.initialize();
});
```
or
```javascript
$(document).ready(function() {
mermaid.initialize();
});
```
Not doing so will most likely result in mermaid rendering graphs that have labels out of bounds. The default integration in mermaid uses the window.load event to start rendering.
If your page has other fonts in its body those might be used instead of the mermaid font. Specifying the font in your styling is a workaround for this.
```css
div.mermaid {
font-family: 'trebuchet ms', verdana, arial;
}
```
### Calling `mermaid.init`
By default, `mermaid.init` will be called when the document is ready, finding all elements with
`class="mermaid"`. If you are adding content after mermaid is loaded, or otherwise need
finer-grained control of this behavior, you can call `init` yourself with:
- a configuration object
- some nodes, as
- a node
- an array-like of nodes
- or W3C selector that will find your nodes
Example:
```javascript
mermaid.init({noteMargin: 10}, ".someOtherClass");
```
Or with no config object, and a jQuery selection:
```javascript
mermaid.init(undefined, $("#someId .yetAnotherClass"));
```
```warning
This type of integration is deprecated. Instead the preferred way of handling more complex integration is to use the mermaidAPI instead.
```
## Usage with webpack
mermaid fully supports webpack. Here is a [working demo](https://github.com/mermaidjs/mermaid-webpack-demo).
## API usage
The main idea of the API is to be able to call a render function with the graph definition as a string. The render function
will render the graph and call a callback with the resulting svg code. With this approach it is up to the site creator to
fetch the graph definition from the site (perhaps from a textarea), render it and place the graph somewhere in the site.
The example below show an outline of how this could be used. The example just logs the resulting svg to the javascript console.
```html
<script src="mermaid.js"></script>
<script>
mermaid.mermaidAPI.initialize({
startOnLoad:false
});
$(function(){
// Example of using the API
var element = document.querySelector("#graphDiv");
var insertSvg = function(svgCode, bindFunctions){
element.innerHTML = svgCode;
};
var graphDefinition = 'graph TB\na-->b';
var graph = mermaid.mermaidAPI.render('graphDiv', graphDefinition, insertSvg);
});
</script>
```
### Binding events
Sometimes the generated graph also has defined interactions like tooltip and click events. When using the API one must
add those events after the graph has been inserted into the DOM.
The example code below is an extract of what mermaid does when using the API. The example shows how it is possible to
bind events to an svg when using the API for rendering.
```javascript
var insertSvg = function(svgCode, bindFunctions) {
element.innerHTML = svgCode;
if(typeof callback !== 'undefined'){
callback(id);
}
bindFunctions(element);
};
var id = 'theGraph';
mermaidAPI.render(id,txt,insertSvg, element);
```
1. The graph is generated using the render call.
2. After generation the render function calls the provided callback function, in this case it's called insertSvg.
3. The callback function is called with two parameters, the svg code of the generated graph and a function. This function binds events to the svg **after** it is inserted into the DOM.
4. Insert the svg code into the DOM for presentation.
5. Call the binding function that binds the events.
## Example of a marked renderer
This is the renderer used for transforming the documentation from markdown to html with mermaid diagrams in the html.
```javascript
var renderer = new marked.Renderer();
renderer.code = function (code, language) {
if(code.match(/^sequenceDiagram/)||code.match(/^graph/)){
return '<div class="mermaid">'+code+'</div>';
}
else{
return '<pre><code>'+code+'</code></pre>';
}
};
```
Another example in coffeescript that also includes the mermaid script tag in the generated markup.
```coffee
marked = require 'marked'
module.exports = (options) ->
hasMermaid = false
renderer = new marked.Renderer()
renderer.defaultCode = renderer.code
renderer.code = (code, language) ->
if language is 'mermaid'
html = ''
if not hasMermaid
hasMermaid = true
html += '<script src="'+options.mermaidPath+'"></script>'
html + '<div class="mermaid">'+code+'</div>'
else
@defaultCode(code, language)
renderer
```
## Advanced usage
**Syntax validation without rendering (Work in Progress)**
The **mermaid.parse(txt)** function validates graph definitions without rendering a graph. **[This function is still a work in progress](https://github.com/mermaid-js/mermaid/issues/1066), find alternatives below.**
The function **mermaid.parse(txt)**, takes a text string as an argument and returns true if the definition follows mermaid's syntax and
false if it does not. The parseError function will be called when the parse function returns false.
When the parser encounters invalid syntax the **mermaid.parseError** function is called. It is possible to override this
function in order to handle the error in an application-specific way.
The code-example below in meta code illustrates how this could work:
```javascript
mermaid.parseError = function(err,hash){
displayErrorInGui(err);
};
var textFieldUpdated = function(){
var textStr = getTextFromFormField('code');
if(mermaid.parse(textStr)){
reRender(textStr)
}
};
bindEventHandler('change', 'code', textFieldUpdated);
```
**Alternative to mermaid.parse():**
One effective and more future-proof method of validating your graph definitions, is to paste and render them via the [Mermaid Live Editor](https://mermaid-js.github.io/mermaid-live-editor/). This will ensure that your code is compliant with the syntax of Mermaid's most recent version.
## Configuration
Mermaid takes a number of options which lets you tweak the rendering of the diagrams. Currently there are three ways of
setting the options in mermaid.
1. Instantiation of the configuration using the initialize call
2. *Using the global mermaid object* - **Deprecated**
3. *using the global mermaid_config object* - **Deprecated**
4. Instantiation of the configuration using the **mermaid.init** call- **Deprecated**
The list above has two ways too many of doing this. Three are deprecated and will eventually be removed. The list of
configuration objects are described [in the mermaidAPI documentation](Setup.md).
## Using the `mermaidAPI.initialize`/`mermaid.initialize` call
The future proof way of setting the configuration is by using the initialization call to mermaid or mermaidAPI depending
on what kind of integration you use.
```html
<script src="../dist/mermaid.js"></script>
<script>
var config = {
startOnLoad:true,
flowchart:{
useMaxWidth:false,
htmlLabels:true
}
};
mermaid.initialize(config);
</script>
```
```tip
This is the preferred way of configuring mermaid.
```
### The following methods are deprecated and are kept only for backwards compatibility.
## Using the mermaid object
Is it possible to set some configuration via the mermaid object. The two parameters that are supported using this
approach are:
* mermaid.startOnLoad
* mermaid.htmlLabels
```javascript
mermaid.startOnLoad = true;
```
```warning
This way of setting the configuration is deprecated. Instead the preferred way is to use the initialize method. This functionality is only kept for backwards compatibility.
```
## Using the mermaid_config
It is possible to set some configuration via the mermaid object. The two parameters that are supported using this
approach are:
* mermaid_config.startOnLoad
* mermaid_config.htmlLabels
```javascript
mermaid_config.startOnLoad = true;
```
```warning
This way of setting the configuration is deprecated. Instead the preferred way is to use the initialize method. This functionality is only kept for backwards compatibility.
```
## Using the mermaid.init call
To set some configuration via the mermaid object. The two parameters that are supported using this approach are:
* mermaid_config.startOnLoad
* mermaid_config.htmlLabels
```javascript
mermaid_config.startOnLoad = true;
```
```warning
This way of setting the configuration is deprecated. Instead the preferred way is to use the initialize method. This functionality is only kept for backwards compatibility.

# User Journey Diagram
> User journeys describe at a high level of detail exactly what steps different users take to complete a specific task within a system, application or website. This technique shows the current (as-is) user workflow, and reveals areas of improvement for the to-be workflow. (Wikipedia)
Mermaid can render user journey diagrams:
```mermaid-example
journey
title My working day
section Go to work
Make tea: 5: Me
Go upstairs: 3: Me
Do work: 1: Me, Cat
section Go home
Go downstairs: 5: Me
Sit down: 5: Me
```
Each user journey is split into sections, these describe the part of the task
the user is trying to complete.
Tasks syntax is `Task name: <score>: <comma separated list of actors>`
