<EdgeLabelRenderer />

Source on GitHub

Edges are SVG-based. If you want to render more complex labels you can use the <EdgeLabelRenderer /> component to access a div based renderer. This component is a portal that renders the label in a <div /> that is positioned on top of the edges. You can see an example usage of the component in the edge label renderer example. We are using the EdgeLabelRenderer internally to render edge labels.

<script lang="ts">
  import { getBezierPath, EdgeLabelRenderer, BaseEdge } from '@xyflow/svelte';
 
  $: [edgePath, labelX, labelY] = getBezierPath(props);
</script>
 
<BaseEdge id={id} path={edgePath} />
<EdgeLabelRenderer>
  <div
    style={{
      position: 'absolute',
      transform: `translate(-50%, -50%) translate(${labelX}px,${labelY}px)`,
      background: '#ffcc00',
      padding: 10,
      borderRadius: 5,
      fontSize: 12,
      fontWeight: 700,
    }}
    className="nodrag nopan"
  >
    {data.label}
  </div>
</EdgeLabelRenderer>

Notes

• The <EdgeLabelRenderer /> has no pointer events by default. If you want to add mouse interactions you need to set the style pointerEvents: all and add the nopan class on the label or the element you want to interact with.
