sails-hook-publisher

Kue based job publisher(producer) for sails v0.11.0+. Its a wrapper around Kue for publishing jobs by using redis as a queue engine.

Installation

$ npm install --save sails-hook-publisher

Usage

In sails hooks, sails.hooks.publisher will be available for use and it will expose:

• queue : a kue based job queue specifially for publish jobs. If you want to consume jobs you may use sails-hook-subscriber. It is a valid kue queue so you can also invoke other kue methods from it. See

• create or createJob : which is a proxy for kue.create and kue.createJob respectively. See kue creating jobs for detailed explanations

Publishing Jobs

Use sails.hooks.publisher.create or sails.hooks.publisher.createJob to publish job(s) as way you used with kue. You can publish jobs in any place within your sails application where sails.hooks is accessible and sails.hook.publisher is loaded and available.

Example

//in AuthController.js
//in register(request,response) method
 
register: function(request,response){
      //your codes ....
 
      //grab publisher
      var publisher = sails.hooks.publisher;
      
      //publish send confirmation email
      var job = publisher.create('email', {
        title: 'Welcome'
      , to: request.email,
      , template: 'welcome-email'
     })
     .save();
}

Note: The above example demostrate sails-hook-publisher usage in controller you can use it in your models and services too

Queue Events

sails-hook-publisher expose queue which is the underlying kue queue it use for listening for queue events. For you to listen on your job events on the queue, just add listener on the publisher queue.on. see kue queue events for more explanation

Example:

//somewhere in your codes just once
//prefered on config/bootstrap.js
//or custom hook
//or services
var publisher = sails.hooks.publisher;
 
//add listener on the queue
publisher
          .queue
          .on('job complete', function(id, jobResult) {
              //your codes here
          });

Configuration

sails-hook-publisher accept application defined configuration by utilizing sails configuration api. In sails config directory add config/publisher.js and you will be able to override all the defauts configurations.

Simply, copy the below and add it to your config/publisher.js

module.exports.publisher = {
    //control activeness of publisher
    //its active by default
    active: true,
                
    //default key prefix for kue in
    //redis server
    prefix: 'q',
 
    //default redis configuration
    redis: {
        //default redis server port
        port: 6379,
        //default redis server host
        host: '127.0.0.1'
    },
