getStraightPath()
Source on GitHub (opens in a new tab)
Calculates the straight line path between two points.
import { getStraightPath } from 'reactflow';
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

#Returns |
|
# [0] | string The path to use in an SVG <path> element. |
# [1] | number The x position you can use to render a label for this edge. |
# [2] | number The y position you can use to render a label for this edge. |
# [3] | number The absolute difference between the source x position and
the x position of the middle of this path. |
# [4] | number 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.
