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.

import React from 'react';
import { getBezierPath, EdgeLabelRenderer, BaseEdge } from '@xyflow/react';
 
const CustomEdge = ({ id, data, ...props }) => {
  const [edgePath, labelX, labelY] = getBezierPath(props);
 
  return (
    <>
      <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>
    </>
  );
};
 
export default CustomEdge;

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.
