GPS web-tracker for many devices

• Simple.
• Based on socket.io and Yandex maps.
• No database, no jquery. Js script minified and gzipped is only 16 Kb.
• Server accepts json messages through tcp like {id:1, lat:10, lng:20}. For devices to send these messages you can use translator server.

Installation

• Clone repository to your server.
• cp browser/config.example.js browser/config.js; paste your Yandex.Maps API key there and adjust serverUrl and browserPort. For local development, set them to http://localhost and 8020.
• cp server/config.example.json server/config.json; don't edit it.
• docker-compose build && docker-compose up.
• Open http://localhost:8020 in your browser and rejoice.

How does it work

                   {id:1,lat:20,lng:30}                          {id:1,lat:20,lng:30}

What is translator server?

Cause each tracker device has its unique protocol to send gps information, there should be a translator server to decode messages from devices and send it in JSON format. The project is hosted here: http://github.com/vinograd19/gps-devices/
