<NodeResizer />
Source on GitHub (opens in a new tab)
The <NodeResizer />
component can be used to add a resize functionality to your
nodes. It renders draggable controls around the node to resize in all directions.
import { memo } from 'react';
import { Handle, Position, NodeResizer } from 'reactflow';
const ResizableNode = ({ data }) => {
return (
<>
<NodeResizer minWidth={100} minHeight={30} />
<Handle type="target" position={Position.Left} />
<div style={{ padding: 10 }}>{data.label}</div>
<Handle type="source" position={Position.Right} />
</>
);
};
export default memo(ResizableNode);
