Hermes is a clone of the Strava app. As such it is best utilized to track your physical exercise and allows you to make customized routes using Google maps.

Technologies

Technologies stack:

  • Ruby on Rails
  • PostgreSQL Database
  • JavaScript
  • React/Redux
  • Google Maps Javascript API
  • Google Maps Directions Service

Features

Routes

Using the Google Maps API, Hermes allows you to:

  • Create a custom route, with google map directions.
  • Edit an existing route
  • Custom markers for every stop
  • A dynamic caluclator that shows distance and estimated time for every marker added.

createPath(){
        const _self = this;
        const waypnt = this.points.slice(1);
      
        const request ={
            origin: this.points[0].location,
            destination: this.points[this.points.length -1].location,
            waypoints: waypnt.map(point => ({location: point.location})),
            travelMode: 'BICYCLING'
        };
        
        this.directionsService.route(request, function(result,status){
            if(status === 'OK'){
                _self.directionsRenderer.setDirections(result);
            }
        });
    }
  • Everytime that a route is created, a static url is also automatically created.

The code for this was:

createStaticUrl(directions){
           const route = directions.routes[0];
           let image = `https://maps.googleapis.com/maps/api/staticmap?size=200x200`;
           const color = `&path=color:red|weight:2|`
           const enc_polyline = `enc:${route.overview_polyline}`;
           const polyline = route.overview_polyline;
           image += color + enc_polyline + '&key=';
           this.setState({
               image_url: image,
               encoded_polyline: polyline
           }); 
             
       }
  • This uses the encoded polyline that is provided through the Google Maps API. This encoded polyline is also used in the update feature, which maps a previous route and lets you change it. ###Workouts
  • You can add a workout manually
  • After a workout is added you can easily edit it.

Future Additions

  • I will be adding a user's dashboard soon as well as user profile pictures.
  • Users will be able to friend each other and see their friends' workouts on their page.
  • Users can comment on each other's workouts.
