primus-redis

Build Status

primus-redis is a Redis store for Primus. It takes care of distributing messages to other instances using Redis Pub/Sub.

Usage

Single Redis instance

You can use primus-redis with a single Redis instance, but it's not recommended in production environment, since it makes Redis a single point of failure.

var http = require('http'),
    Primus = require('primus'),
    PrimusRedis = require('primus-redis');
 
var server = http.createServer();
var primus = new Primus(server, {
  redis: {
    host: 'localhost',
    port: 6379,
    channel: 'primus' // Optional, defaults to `'primus`'
  },
  transformer: 'websockets'
});
primus.use('Redis', PrimusRedis);
 
//
// This'll take care of sending the message to all other instances connected
// to the same Redis channel.
//
primus.write('Hello world!'); 

Sentinel

Redis Sentinel is a failover mechanism built into Redis.

When using Sentinel, Redis client will automatically reconnect to new master server when current one goes down.

var http = require('http'),
    Primus = require('primus'),
    PrimusRedis = require('primus-redis');
 
var server = http.createServer();
var primus = new Primus(server, {
  redis: {
    sentinel: true,
    endpoints: [
      { host: 'localhost', port: 26379 },
      { host: 'localhost', port: 26380 },
      { host: 'localhost', port: 26381 }
    ],
    masterName: 'mymaster'
    channel: 'primus' // Optional, defaults to `'primus`'
  },
  transformer: 'websockets'
});
primus.use('Redis', PrimusRedis);
