RoutingJS
One lib to route them all : RoutingJS is a promise-based web client for accessing different +routing web services, analogous to our Python client routingpy. Get unified access to several routing services with the power of modern asynchronous JavaScript fully typed thanks to the power of TypeScript!
We currently support the following routers:
Future support for other service (like the ones routingpy is supporting) might come at a later stage.
Installation
Router clients are installable individually:
npm install @routingjs/valhalla
Examples
RoutingJS offers directions, matrix and reachability methods where available (e.g. OSRM does not support reachability/isochrones).
import { Valhalla } from "@routingjs/valhalla"
const v = new Valhalla() // URL defaults to http://valhalla1.openstreetmap.de
v.directions(
[
[47.380742, 8.512516], // pass as [lat, lon]
[47.359467, 8.557835],
],
"auto"
).then((d) => {
// do stuff with the directions response
d.directions.forEach((direction) => {
console.log(direction.feature) // get the route as GeoJSON feature
console.log(direction.feature.properties.distance) // get the route distance
console.log(direction.feature.properties.duration) // get the route duration
})
})
v.reachability([47.380742, 8.512516], "pedestrian", [30, 90]).then((i) => {
i.isochrones.forEach((isochrone) => {
console.log(i.interval) // 30/90
console.log(i.intervalType) // "time"
console.log(i.feature) // GeoJSON feature
})
})
v.matrix(
[
[47.380742, 8.512516], // pass as [lat, lon]
[47.359467, 8.557835],
],
"auto"
).then((m) => {
console.log(m.durations) // get the durations array for each location
console.log(m.distances) // get the distances array for each location
})

Contributions are welcome! We are open to improvements of existing clients, as well as additions of +new ones :-)
