Realtime (Push) notifications based on Redis pub/sub, node.js and socket.io
===========================================================================
The aim of this example is to provide a small guide for implementing
realtime notifications based on redis and socket.io (with node.js)
Schema
------
Client that pushes notifications -> Redis -> Node.js/Socket.io -> User browser
Requirements
------------
- [Node](http://nodejs.org/)
- [Redis](http://redis.io)
Running
-------
In the project folder install [socket.io](http://socket.io/) and node [redis client](https://github.com/mranney/node_redis):
npm install socket.io redis
Start the redis database:
$ redis-server
Start the push notifications server:
$ node ./app.js
Start the client node server:
$ cd ./test-client
$ node ./client.js
Open a browser and go to 127.0.0.1:8000, enter the id that you want and we are
ready to push some notifications.
Open a redis client:
$ redis-cli
And with this key **push:notifications:[ID]** we publish messages into redis.
$ PUBLISH "push:notifications:slok" "Justin Bieber sucks"
So all the published messages in the appropiate redis channels, will be
pushed to the user browser in realtime :)
Now we should see the message **Justin Bieber sucks** in the message list
