## 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, yarn or pnpm:

```bash
npm install reactflow
```

## 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 { useCallback } from 'react';
import ReactFlow, {
  MiniMap,
  Controls,
  Background,
  useNodesState,
  useEdgesState,
  addEdge,
} from 'reactflow';

import 'reactflow/dist/style.css';

const initialNodes = [
  { id: '1', position: { x: 0, y: 0 }, data: { label: '1' } },
  { id: '2', position: { x: 0, y: 100 }, data: { label: '2' } },
];

const initialEdges = [{ id: 'e1-2', source: '1', target: '2' }];

function Flow() {
  const [nodes, setNodes, onNodesChange] = useNodesState(initialNodes);
  const [edges, setEdges, onEdgesChange] = useEdgesState(initialEdges);

  const onConnect = useCallback((params) => setEdges((eds) => addEdge(params, eds)), [setEdges]);

  return (
    <ReactFlow
      nodes={nodes}
      edges={edges}
      onNodesChange={onNodesChange}
      onEdgesChange={onEdgesChange}
      onConnect={onConnect}
    >
      <MiniMap />
      <Controls />
      <Background />
    </ReactFlow>
  );
}
```

## Development

Before you can start developing please make sure that you have [pnpm](https://pnpm.io/) installed (`npm i -g pnpm`). Then install the dependencies using pnpm: `pnpm install`.

For local development, you can use `pnpm dev`.

## Testing

Testing is done with cypress. You can find the tests in the [`examples/cypress`](/examples/cypress/) folder. In order to run the tests do:

```sh
pnpm test
```

## Credits

React Flow was initially developed for [datablocks](https://datablocks.pro), a graph-based editor for transforming, analyzing and visualizing data in the 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
- [d3-drag](https://github.com/d3/d3-drag) - used for making the nodes draggable
- [zustand](https://github.com/pmndrs/zustand) - internal state management
