getSmartEdge

Central path computation API. Returns { svgPathString, edgeCenterX, edgeCenterY } on success, or an Error if no valid path was found.

import { getSmartEdge } from "@tisoap/react-flow-smart-edge";

const result = getSmartEdge({
  sourcePosition,
  targetPosition,
  sourceX,
  sourceY,
  targetX,
  targetY,
  nodes,
  options: {
    nodePadding: 10,
    gridRatio: 10,
  },
});

if (result instanceof Error) {
  // fall back to a default edge
} else {
  const { svgPathString, edgeCenterX, edgeCenterY } = result;
}

Parameters

Key	Description
sourceX, sourceY, targetX, targetY	Handle coordinates
sourcePosition, targetPosition	Handle sides (Position enum)
nodes	All graph nodes (from useNodes)
options?	See Options

Pipeline

nodes + endpoints → bounding boxes → grid → walkability → A* → SVG path
