<h1>Using GoJS with React</h1>
<p class="box" style="background-color: lightgoldenrodyellow;">
Examples of most of the topics discussed on this page can be found in the <a href="https://github.com/NorthwoodsSoftware/gojs-react-basic" target="_blank">gojs-react-basic</a> project,
which serves as a simple starter project.
</p>
<p>
If you are new to GoJS, it may be helpful to first visit the <a href="../learn/index.html" target="_blank">Getting Started Tutorial</a>.
</p>
<p>
The easiest way to get a component set up for a GoJS Diagram is to use the <a href="https://github.com/NorthwoodsSoftware/gojs-react" target="_blank">gojs-react</a> package,
which exports React Components for GoJS Diagrams, Palettes, and Overviews.
The <a href="https://github.com/NorthwoodsSoftware/gojs-react-basic" target="_blank">gojs-react-basic</a> project demonstrates how to use these components.
More information about the package, including the various props it takes, can be found on the <a href="https://github.com/NorthwoodsSoftware/gojs-react" target="_blank">Github</a> or
<a href="https://npmjs.com/gojs-react" target="_blank">NPM</a> pages. Our examples will be using a <a>GraphLinksModel</a>, but any model can be used.
</p>
<h2 id="quickstart">Quick start with an existing React application</h2>
<h4 id="Installation">Installation</h4>
<p>
Start by installing GoJS and gojs-react: <code>npm install gojs gojs-react</code>.
</p>
<h4 id="DiagramStyling">Diagram styling</h4>
<p>
Next, set up a CSS class for the GoJS diagram's div:
</p>
<pre class="lang-css"><code>
/* App.css */
.diagram-component {
width: 400px;
height: 400px;
border: solid 1px black;
background-color: white;
}
</code></pre>
<h4 id="RenderingComponent">Rendering the component</h4>
<p>
Finally, add an initDiagram function and a model change handler function, and add the ReactDiagram component inside your render method.
Note that the UndoManager should always be enabled to allow for transactions to take place,
but the <a>UndoManager.maxHistoryLength</a> can be set to 0 to prevent undo and redo.
</p>
<pre class="lang-js"><code>
// App.js
import React from 'react';
import * as go from 'gojs';

<p>
That's it! You should now have a GoJS diagram rendering within your React application.
Try editing the text of a node or deleting a node, and you'll see an alert on the page.
</p>
<h2 id="stateful">Usage in a stateful React app</h2>
<p>
Typically the data being passed to the ReactDiagram component will be used elsewhere in your app and will exist in React state.
For example, you may have some kind of inspector that can be used to modify node properties, and therefore the state should be lifted up and held by a parent component
of both the diagram and the inspector.
</p>
<p>
A basic setup can be seen in the <a href="https://github.com/NorthwoodsSoftware/gojs-react-basic" target="_blank">gojs-react-basic</a> project,
but we'll describe some of the methodology here.
</p>
<h4 id="CreatingWrapperComponent">Creating a wrapper component</h4>
<p>
When handling state, it is often useful to write a wrapper component around the gojs-react components to pass the necessary props along and keep GoJS initialization out of the main app.
There are a few things that should be set up in the wrapper component:
<ul>
<li>a set of props coming in from the parent component which holds state and handlers</li>
<li>a ref to the ReactDiagram component so getDiagram() and clear() can be used</li>
<li>componentDidMount and componentWillUnmount methods to add/remove app-specific diagram listeners</li>
<li>an initDiagram method to be passed to the ReactDiagram component</li>
</ul>
Node and link data are <i>merged</i> into the GoJS model, thus properties should not be removed from node or link data,
but rather set to undefined if they are no longer needed; GoJS avoids destructive merging.
</p>
<p>
Below, we'll pass linkDataArray and modelData as props to the ReactDiagram, but note that they are not always needed in gojs-react components,
so your app may not need to include them. For proper initial loading of data, one should have the data ready before the ReactDiagram component mounts.
This allows layouts and linking to occur properly with the initial data set.
</p>

<h4>A Note on Diagram Reinitialization</h4>
<p>
Occasionally you may want to treat a model update as if you were loading a completely new model.
But initialization is done via the initDiagram function, within the componentDidMount lifecycle method, and only once.
A regular model update is not treated as an initialization, so none of the <b>initial...</b> properties
of your Diagram will apply.
</p>
<p>
To address this problem, ReactDiagram exposes a clear() method.
When called, it clears its diagram of all nodes, links, and model data, and
prepares the next state update to be treated as a diagram initialization.
That will result in an initial layout and perform initial diagram content alignment and scaling.
Note that the initDiagram function is not called again.
</p>
<p>
Here is a small sample of how one might trigger diagram reinitilization using the clear() method.
</p>
<pre class="lang-js"><code>
public reinitModel() {
this.diagramRef.current.clear();
this.setState({
nodeDataArray: [
{ key: 0, text: 'Epsilon', color: 'lightblue' },
{ key: 1, text: 'Zeta', color: 'orange' },
{ key: 2, text: 'Eta', color: 'lightgreen' },
{ key: 3, text: 'Theta', color: 'pink' }
],
linkDataArray: [
{ key: -1, from: 0, to: 1 },
{ key: -2, from: 0, to: 2 },
{ key: -3, from: 1, to: 1 },
{ key: -4, from: 2, to: 3 },
{ key: -5, from: 3, to: 0 }
],
skipsDiagramUpdate: false
});
}
