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>
  );
}

Development

Before you start you need to build the project using npm run build. Then 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
  • d3-drag - used for making the nodes draggable
  • zustand - internal state management
