OptimizeWaypoints

Source: src/AWS/GeoRoutes/OptimizeWaypoints.ts

Runtime binding for geo-routes:OptimizeWaypoints — calculate the optimal order to visit a set of waypoints, minimizing travel time or distance (the traveling-salesman step of delivery/route planning).

geo-routes is a standalone, pay-per-call Amazon Location API with no resource to manage: the binding takes no arguments and grants the function geo-routes:OptimizeWaypoints. Requests and responses are raw distilled types (positions are [longitude, latitude] pairs).

Optimizing Waypoints

Provide the OptimizeWaypointsHttp implementation layer on the Function effect (.pipe(Effect.provide(AWS.GeoRoutes.OptimizeWaypointsHttp))), bind in the init phase, then call the client at runtime.

// init
const optimizeWaypoints = yield* AWS.GeoRoutes.OptimizeWaypoints();

// runtime — positions are [longitude, latitude]
const result = yield* optimizeWaypoints({
  Origin: [-122.339, 47.61],
  Destination: [-122.201, 47.61],
  Waypoints: [
    { Id: "stop-1", Position: [-122.335, 47.608] },
    { Id: "stop-2", Position: [-122.313, 47.62] },
  ],
});
const order = result.OptimizedWaypoints.map((w) => w.Id);
