Leaflet.Routing is a routing controller for the popular Leaflet mapping framework. The module provides an intuitive interface for routing paths between waypoints using any user specified routing service. A demo using the OSM data can be found here.

• Route handling interface for Leaflet
• Use your own routing backend, or OSM

var routing = new L.Routing({
  position: 'topright'
  ,routing: {
    router: myRouterFunction
  }
  ,tooltips: {
    waypoint: 'Waypoint. Drag to move; Click to remove.',
    segment: 'Drag to create a new waypoint'
  }
  ,styles: {     // see http://leafletjs.com/reference.html#polyline-options
    trailer: {}  // drawing line
    ,track: {}   // calculated route result
    ,nodata: {}  // line when no result (error)
  }
  ,snapping: {
    layers: [mySnappingLayer]
    ,sensitivity: 15
    ,vertexonly: false
  }
  ,shortcut: {
    draw: {
      enable: 68    // 'd'
      ,disable: 81  // 'q'
    }
  }
});
map.addControl(routing);

routing.draw(true);

routing.routing(true);

routing.snapping(true);

routing.rerouteAllSegments(callback);

var first = routing.getFirst();

var last = routing.getLast();

var waypointsArray = routing.getWaypoints();

var polyline = routing.toPolyline();

var geoJSON3D = routing.toGeoJSON();
var geoJSON2D = routing.toGeoJSON(false);

Load GeoJSON with and without properties.waypoints.

• number waypointDistance - distance between inserted waypoints for GeoJSON without waypoints.
• boolean fitBounds - fit map arround loaded GeoJSON.

routing.loadGeoJSON(geojson, [options], function(err) {
  if (err) {
    console.log(err);
  } else {
    console.log('Finished loading GeoJSON');
  }
});

All events form Leaflet.Routing is prefixed with routing:.

routing.on('routing:someEvent', function() {
  console.log('routing:someEvent triggered');
});
