xyflow Goto Github PK

The xyflow repository is the home of four packages:

• React Flow 11 reactflow v11 branch
• React Flow 12 (beta) @xyflow/react packages/react
• Svelte Flow @xyflow/svelte packages/svelte
• Shared helper library @xyflow/system packages/system

We just moved repositories from the @wbkd org to this one. React Flow v11 will remain on the v11 branch. When we have a stable v12, the package name of React Flow will change from reactflow to @xyflow/react.

Are you using React Flow or Svelte Flow for a personal project? Great! No sponsorship needed, you can support us by reporting any bugs you find, sending us screenshots of your projects, and starring us on Github 🌟

Are you using React Flow or Svelte Flow at your organization and making money from it? Awesome! We rely on your support to keep our libraries developed and maintained under an MIT License, just how we like it. For React Flow you can do that on the React Flow Pro website and for both of our libraries you can do it through Github Sponsors.

The best way to get started is to check out the React Flow or Svelte Flow learn section. However if you want to get a sneak peek of how to install and use the libraries you can see it here:

npm install reactflow

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;

npm install @xyflow/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 />
</SvelteFlow>
