Edge Types

You can choose different kinds of edge types in React Flow: default (bezier), straight, step and smoothstep. As you can see, you can define a type for each edge and mix them in one graph.

import React, { useCallback } from 'react';
import {
  ReactFlow,
  useNodesState,
  useEdgesState,
  addEdge,
  Controls,
  Background,

const initialNodes = [
  {
    id: '1',
    data: { label: 'choose' },
    position: {
      x: 0,
      y: 0,
    },
  },
  {
    id: '2',
    data: { label: 'your' },
    position: {
      x: 100,
      y: 100,
    },
  },
  {
    id: '3',
    data: { label: 'desired' },
    position: {
      x: 0,
      y: 200,
    },
  },
  {
    id: '4',
    data: { label: 'edge' },
    position: {
      x: 100,
      y: 300,
    },
  },
  {
    id: '5',
    data: { label: 'type' },
    position: {
      x: 0,
      y: 400,

  const [edges, setEdges, onEdgesChange] = useEdgesState(initialEdges);
  const onConnect = useCallback(
    (params) => setEdges((eds) => addEdge(params, eds)),
    [],
