RethinkPush

Works almost like firebase - Internal hosted solution powered by RethinkDB, Node.js, Express.js and Socket.IO

Data pushed to RethinkDB synchronized in realtime to every connected client via WebSocket

• Use of RethinkDB Changefeeds for Realtime messaging
• Socket.IO enables real-time bidirectional event-based communication. It works on every platform, browser or device, focusing equally on reliability and speed.

How does it work

direct

• client app: web browser (use WebSocket)
• app: RESTful API Server
• RethinkPush: push notification service
• RethinkDB: JSON doc storage (in lieu of Firebase)

  'channel': 'public',
  'message': {'greeting': 'Ahoy from RethinkDB'}
});

Roadmap

• docker or vagrant for quick up and running
• primitive authentication
  • app wide secret key
• add more tests and run on jenkins
• production provisioning with pm2
• add ts_to_send for scheduled notification
  • add filter on changes query
• REST api
  • post notification
  • subscription level authentication
• make record deletion optional after notification is sent

ref:

• expressjs
• rethinkdb
• chai
