React Flow is a library for building node-based graphs. You can easily implement custom node types and it comes with components like a mini-map and graph controls. Feel free to check out the [examples](https://reactflow.dev/) or read the [blog post](https://webkid.io/blog/react-flow-node-based-graph-library/) to get started.

## Installation
|
|
|
|
```
|
|
npm install react-flow-renderer
|
|
```
|
|
|
|
## Quick Start
|
|
|
|
This is a very basic example of how to use React Flow. You can find more advanced examples on the [website](https://reactflow.dev/examples).
|
|
|
|
```javascript
|
|
import React from 'react';
|
|
import ReactFlow from 'react-flow-renderer';
|
|
|
|
const elements = [
|
|
{ id: '1', data: { label: 'Node 1' }, position: { x: 250, y: 5 } },
|
|
// you can also pass a React component as a label
|
|
{ id: '2', data: { label: <div>Node 2</div> }, position: { x: 100, y: 100 } },
|
|
{ id: 'e1-2', source: '1', target: '2', animated: true },
|
|
];
|
|
|
|
const BasicFlow = () => <ReactFlow elements={elements} />;
|
|
```
|
|
|
|
## Development
|
|
|
|
You need to install the React Flow dependencies via `npm install` and the ones of the examples `cd example && npm install`.
|
|
|
|
If you want to contribute or develop custom features the easiest way is to start the dev server:
|
|
|
|
```
|
|
npm run dev
|
|
```
|
|
|
|
This serves the content of the `example` folder and watches changes inside the `src` folder. The examples are using the source of the `src` folder.
|
|
|
|
## Testing
|
|
|
|
Testing is done with cypress. You can find the tests in the [`integration/flow`](/cypress/integration/flow) folder. In order to run the tests do:
|
|
|
|
```
|
|
npm run test
|
|
```
|
|
|
|
