gps-server

About

Basically, gps-server is aimed to support various GPS hardware devices and different data protocols. Both binary and string-based protocols can be supported, including NMEA-like ones.

There is a map page available to see your GPS devices tracked in real-time. Just go to configured HTTP endpoint in your browser.

TBD: Also, some admin UI provided to get an idea what's going on under the hood, with some of logs out to see in real-time in your browser.

Main goals are to keep it:

• lightweight
• extensible
• configurable
• easy-to-use

...and that's it. Simple.

How to use

as npm package

gps-server can be used as npm package, in external app. In your app's folder, do:

npm install gps-server

To save dependency in your package.json: npm install gps-server --save

Then, in your app just add:

var gpsServer = require('gps-server');
//  start GPS server
gpsServer();

See server.js for usage example.

as standalone server

After cloning or downloading this repository, you can run it as standalone server:

node server.js

Usually, it's a good idea to use some helper packages, like forever. See server.js for some more info.

Functionality and Features

@0.3.0

• tested against real GPS devices, workable with:
  • Bitrek / Teltonika binary protocol
  • GlobalSat NMEA-like string protocol
• can be used as npm package now, in external app

v2015

• server listening for data
• logging of received data -> into file under /log
• parsing GPS data
• UI: map.html, for real-time GPS position rendering
• UI: chat.html (socket.io demo)
• broadcasting socket.io message -> subscribed listeners on UI
• saving data into MySQL DB
• configuration support, limited
• bower used for front-end dependencies
• /libs used
• custom unit tests used
• custom demo.js for demoing / testing

TODO

• add:
  • arrange universal parsing flow using adapters (parsers for specific formats ?)
    • binary:
      • BiTrek
      • Teltonika
    • string (NMEA ?) format:
      • GlobalSat:
        • reports: GSr
        • config and other packets
      • Elgato Ukr
      • Queclink ?
    • unclear:
      • RCS TeleTrack
  • support NMEA format, via existing js module ?
  • introduce 'extension point' to use parsed data
  • unit tests - karma ?
  • stress tests / highload ?
  • support for demo mobile app
  • support for OsmAnd mobile clients ?
  • cloud support / cloud demo (note: RH cloud HTTP+TCP ports config issue)
  • UI: parameter support for showing one device or group ?
  • admin UI:
    • page with current / active metrics (# of connected devices and/or UI users)
    • log page (events/usage listing), with e.g. ~1,000 lines max
• remove:
  • remove: saving into DB
  • remove: chat.html (socket.io demo)
  • remove: /libs dependencies
  • remove: bower usage and dependencies ?
• configuration:
  • setup project through the package.json
  • arrange npm "scripts"
  • extend configuration support
