getBezierPath()

Source on GitHub

The getBezierPath util returns everything you need to render a bezier edge between two nodes.

import { Position, getBezierPath } from '@xyflow/react';
 
const source = { x: 0, y: 20 };
const target = { x: 150, y: 100 };
 
const [path, labelX, labelY, offsetX, offsetY] = getBezierPath({
  sourceX: source.x,
  sourceY: source.y,
  sourcePosition: Position.Right,
  targetX: target.x,
  targetY: target.y,
  targetPosition: Position.Left,
});
 
console.log(path); //=> "M0,20 C75,20 75,100 150,100"
console.log(labelX, labelY); //=> 75, 60
console.log(offsetX, offsetY); //=> 75, 40

Signature

The getBezierPath util returns everything you need to render a bezier edge between two nodes.

Parameters

• [0].sourceX: number The x position of the source handle.
• [0].sourceY: number The y position of the source handle.
• [0].sourcePosition?: Position The position of the source handle.
• [0].targetX: number The x position of the target handle.
• [0].targetY: number The y position of the target handle.
• [0].targetPosition?: Position The position of the target handle.
• [0].curvature?: number The curvature of the bezier edge.

Returns

[path: string, labelX: number, labelY: number, offsetX: number, offsetY: number]

Notes

• This function returns a tuple (aka a fixed-size array) to make it easier to work with multiple edge paths at once.
