Attribution
React Flow includes a small attribution that links to the React Flow website. Per default the attribution is displayed in the bottom right corner. With the attribution we want to achieve that companies who are using React Flow in commercial applications finance the development of the library. We expect users who are using React Flow commercially to subscribe to React Flow Pro if they want to remove the attribution. In non-commercial applications you may hide the attribution without subscribing but are welcome to sponsor us on Github.
Installation
The easiest way to get the latest version of React Flow is to install it via npm:
npm install react-flow-renderer
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 for guides, examples and API reference.
import ReactFlow, { MiniMap, Controls } from 'react-flow-renderer';
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:
npm start
and the example app via:
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
folder. In order to run the tests do:
npm run test

Credits
React Flow was initially developed for datablocks, 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 - used for zoom, pan and drag interactions with the graph canvas
- react-draggable - used for making the nodes draggable
- zustand - internal state management
