redis-queue

Description

Node-redis-queue is a simple Redis based message queue for communicating between multiple platforms. It uses a easy to implement message paradigm within Redis lists.

An example message:

{
  id: 1,
  payload: 'Some data',
  errors: ['HTTP 404'],
  error_count: 1
}

Messages are put onto the list with rpush, then the client listens for messages with the blpop command.

Usage

queue-server.js:

// Require the node-redis-queue var client = require('./node-redis-queue');

// Create the Queue with a redis server listening on localhost:6379 var user_queue = new client.Queue({ name: 'user', host: 'localhost', port: 6379 });

// Add a job to the queue. user_queue.push('Any JSON.strinify-able data goes in this parameter', function (error, id) { // Handle errors if (error) throw error; // Second parameter is the message/job id. });

queue-worker.js:

// Require the node-redis-queue var client = require('./node-redis-queue');

// Create a worker for each queue. var worker = client.createWorker({ name: 'user', host: 'localhost', port: 6379 });

// Setup message event worker.on('message', function (job) { // Process message process(job.payload);

// Listen for next job worker.next(); });

// Start listening. worker.start();
