useHandleConnections()

useHandleConnections is deprecated in favor of the more capable useNodeConnections.

This hook can be used to get notified when the connections of a handle change.


<script lang="ts">
  import { useHandleConnections } from '@xyflow/svelte';
 
  const connections = useHandleConnections({ nodeId: 'node-id', type: 'target' });
 
  $: {
    // This will be called whenever connections change
    // for the target handle in the node with id 'node-id'
    console.log($connections);
  }
</script>
