## Key Features
|
|
|
|
- **Easy to use:** Seamless zooming and panning, single- and multi selection of graph elements and keyboard shortcuts are supported out of the box
|
|
- **Customizable:** Different [node](https://reactflow.dev/docs/api/nodes/node-types) and [edge types](https://reactflow.dev/docs/api/edges/edge-types) and support for custom nodes with multiple handles and custom edges
|
|
- **Fast rendering:** Only nodes that have changed are re-rendered and only those in the viewport are displayed
|
|
- **Hooks and Utils:** [Hooks](https://reactflow.dev/docs/api/hooks/use-react-flow) for handling nodes, edges and the viewport and graph [helper functions](https://reactflow.dev/docs/api/graph-util-functions)
|
|
- **Plugin Components:** [Background](https://reactflow.dev/docs/api/plugin-components/background), [MiniMap](https://reactflow.dev/docs/api/plugin-components/minimap) and [Controls](https://reactflow.dev/docs/api/plugin-components/controls)
|
|
- **Reliable**: Written in [Typescript](https://www.typescriptlang.org/) and tested with [cypress](https://www.cypress.io/)

## Installation
|
|
|
|
The easiest way to get the latest version of React Flow is to install it via npm:
|
|
|
|
```bash
|
|
npm install @react-flow/core
|
|
```
|
|
|
|
## Quick Start
|
|
|
|
This is only a very basic usage example of React Flow. To see everything that is possible with the library, please refer to the [website](https://reactflow.dev) for [guides](https://reactflow.dev/docs/guides/custom-nodes), [examples](https://reactflow.dev/docs/examples/overview) and [API reference](https://reactflow.dev/docs/api/react-flow-props).
|
|
|
|
```jsx
|
|
import ReactFlow, { MiniMap, Controls } from '@react-flow/core';
|
|
|
|
function Flow({ nodes, edges, onNodesChange, onEdgesChange, onConnect }) {
|
|
return (
|
|
<ReactFlow
|
|
nodes={nodes}
|
|
edges={edges}
|
|
onNodesChange={onNodesChange}
|
|
onEdgesChange={onEdgesChange}
|
|
onConnect={onConnect}
|
|
>
|
|
<MiniMap />
|
|
<Controls />
|
|
</ReactFlow>
|
|
);
|
|
}
|
|
```
|
|
|
|
Before you start 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:
|
|
|
|
```sh
|
|
npm start
|
|
```
|
|
|
|
and the example app via:
|
|
|
|
```sh
|
|
cd example && npm start
|
|
```
|
|
|
|
The example app 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:
|
|
|
|
```sh
|
|
npm run test
|
|
```
|
|
|
|
## Attribution
|
|
|
|
Since v10.0.0 the React Flow renderer includes a small attribution that links to the React Flow website. It is only allowed to remove the attribution if you are subscribed to one of the [pro plans](https://pro.reactflow.dev/pricing). A subscription also provides more features such as a private Discord channel with the creators of React Flow or access to the source code of Datablocks (a node-based data editor built with React Flow).

## Credits
|
|
|
|
React Flow was initially developed for [datablocks](https://datablocks.pro), a graph-based editor for transforming, analyzing and visualizing data in your browser. Under the hood, React Flow depends on these great libraries:
|
|
|
|
* [d3-zoom](https://github.com/d3/d3-zoom) - used for zoom, pan and drag interactions with the graph canvas
|
|
* [react-draggable](https://github.com/react-grid-layout/react-draggable) - used for making the nodes draggable
|
|
* [zustand](https://github.com/pmndrs/zustand) - internal state management
