Design Phase 4 - Routes Controller Example

routesController.js

// api/routes?start=300 main st boston&end=550 elm st boston&cost_table=popularity&route_type=cycle
app.get('api/routes', function(req,res){
  //Parse Request for parameters
  var start = req.params.start,
      end = req.params.end,
      costTable = req.params.cost_table,
      routeType = req.params.route_type;
  //Geocode Start and End
  geoCoder.geocode([start,end], function(geoCodedResponse){
    
    //Get Route from routingService
    routingService.getRoute(geoCodedResponse[0].lat,
                            geoCodedResponse[0].lon,
                            geoCodedResponse[1].lat,
                            geoCodedResponse[1].lon,
                            routeType,
                            costTable,
                            function(route) {
                              //Send route as response to request
                              res.send(route);
                            });
