getStraightPath()

Calculates the straight line path between two points.


import { getStraightPath } from '@xyflow/react';
 
const source = { x: 0, y: 20 };
const target = { x: 150, y: 100 };
 
const [path, labelX, labelY, offsetX, offsetY] = getStraightPath({
  sourceX: source.x,
  sourceY: source.y,
  targetX: target.x,
  targetY: target.y,
});
 
console.log(path); //=> "M 0,20L 150,100"
console.log(labelX, labelY); //=> 75, 60
console.log(offsetX, offsetY); //=> 75, 40

Signature

Parameters:

Name	Type	Default
`[0].sourceX`	`number` The `x` position of the source handle.
`[0].sourceY`	`number` The `y` 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.

Returns:

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

A path string you can use in an SVG, the labelX and labelY position (center of path) and offsetX, offsetY between source handle and label.

path: the path to use in an SVG <path> element.
labelX: the x position you can use to render a label for this edge.
labelY: the y position you can use to render a label for this edge.
offsetX: the absolute difference between the source x position and the x position of the middle of this path.
offsetY: the absolute difference between the source y position and the y position of the middle of this path.

Notes

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