## The xyflow mono repo

The xyflow repository is the home of four packages:
* React Flow 11 `reactflow` [v11 branch](https://github.com/xyflow/xyflow/tree/v11)
* React Flow 12 (beta) `@xyflow/react` [packages/react](./packages/react)
* Svelte Flow `@xyflow/svelte` [packages/svelte](./packages/svelte)
* Shared helper library `@xyflow/system` [packages/system](./packages/system)

**We just moved repositories** from the @wbkd org to this one. React Flow v11 will remain on the [v11 branch](https://github.com/xyflow/xyflow/tree/v11). When we have a stable v12, the package name of React Flow will change from `reactflow` to `@xyflow/react`.

## Getting started

The best way to get started is to check out the [React Flow](https://reactflow.dev/learn) or [Svelte Flow](https://svelteflow.dev/learn) learn section. However if you want to get a sneak peek of how to install and use the libraries you can see it here:

  <summary><strong>React Flow</strong> basic usage</summary>

  ### Installation
  
  ```sh
npm install reactflow
  ```

  ### Basic usage
  ```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>
  );
}

export default Flow;
```

  ### Installation
  
  ```sh
npm install @xyflow/svelte
  ```

  ### Basic usage
  ```svelte
<script lang="ts">
  import { writable } from 'svelte/store';
  import {
    SvelteFlow,
    Controls,
    Background,
    BackgroundVariant,
    MiniMap,
  } from '@xyflow/svelte';

  import '@xyflow/svelte/dist/style.css'
  
  const nodes = writable([
    {
      id: '1',
      type: 'input',
      data: { label: 'Input Node' },
      position: { x: 0, y: 0 }
    },
    {
      id: '2',
      type: 'custom',
      data: { label: 'Node' },
      position: { x: 0, y: 150 }
    }
  ]);

  const edges = writable([
    {
      id: '1-2',
      type: 'default',
      source: '1',
      target: '2',
      label: 'Edge Text'
    }
  ]);
</script>

<SvelteFlow
  {nodes}
  {edges}
  fitView
  on:nodeclick={(event) => console.log('on node click', event)}
>
  <Controls />
  <Background variant={BackgroundVariant.Dots} />
  <MiniMap />
