This hook returns the edge with the specified ID. When you subscribe, it will trigger whenever the edge changes. This happens when the edge is updated. The return value exposes a .current property to access the edge.

<script lang="ts">
  import { useEdge } from '@xyflow/svelte';
 
  const edge = useEdge('edge-id');
 
  $inspect(edge.current);
