NodeProps<T>

When you implement a custom node it is wrapped in a component that enables basic functionality like selection and dragging.

Usage


import { useState } from 'react';
import { NodeProps, Node } from '@xyflow/react';
 
export type CounterNode = Node<
  {
    initialCount?: number;
  },
  'counter'
>;
 
export default function CounterNode(props: NodeProps<CounterNode>) {
  const [count, setCount] = useState(props.data?.initialCount ?? 0);
 
  return (
    <div>
      <p>Count: {count}</p>
      <button className="nodrag" onClick={() => setCount(count + 1)}>
        Increment
      </button>
    </div>
  );
}

Remember to register your custom node by adding it to the nodeTypes prop of your <ReactFlow /> component.


import { ReactFlow } from '@xyflow/react';
import CounterNode from './CounterNode';
 
const nodeTypes = {
  counterNode: CounterNode,
};
 
export default function App() {
  return <ReactFlow nodeTypes={nodeTypes} ... />
}
