Support and New Features

Leaflet Routing Machine is in many ways already a feature complete routing UI. Most likely, your requirements are already covered and require very little adaptation.

Building

npm install

This requires Node and npm.

Usage

via npm/yarn (the preferred way):

npm install --save leaflet-routing-machine

Please Note: If you want to use osrm-text-instructions for routing instructions, you need to add it as a dependency yourself

npm i --save osrm-text-instructions

var L = require('leaflet');
require('leaflet-routing-machine');

// or, if you prefer modern ES6 imports
import * as L from 'leaflet';
import 'leaflet-routing-machine';

...

alternatively, if you do not use a bundler:

Download latest release, or obtain the latest release via unpkg.com.

<link rel="stylesheet" href="https://unpkg.com/[email protected]/dist/leaflet-routing-machine.css" />
<script src="https://unpkg.com/[email protected]/dist/leaflet-routing-machine.js"></script>

Please note: From v4 this will not include osrm-text-instructions anymore so you need to configure your own language mapping or stay on v3

LRM attaches itself onto L.
