ReferenceHooks

useEdges()

Source on GitHub 

This hook returns an array of the current edges. Components that use this hook will re-render whenever any edge changes.

import { useEdges } from '@xyflow/react'; export default function () { const edges = useEdges(); return <div>There are currently {edges.length} edges!</div>; }

Signature

Parameters:

This function does not accept any parameters.

Returns:

TypeScript

This hook accepts a generic type argument of custom edge types. See this section in our TypeScript guide for more information.

const nodes = useEdges<CustomEdgeType>();

Notes

  • Relying on useEdges unnecessarily can be a common cause of performance issues. Whenever any edge changes, this hook will cause the component to re-render. Often we actually care about something more specific, like when the number of edges changes: where possible try to use useStore instead.
