    redis: {
        port: 6379,

        password: ''
    }
}

See bull.queue for more information.

Examples

Bull queue definition in api/queues/my-queue.js

module.exports = {
  queueName: 'my-queue',
  // if redis already defined as an object, url will be ignored
  url: 'redis://127.0.0.1:6379',
  opts: {
    limiter: {
        max: 1000,
        duration: 5000
    }
  },
  /**
   * If "false" it only allows adding object to queue. It does not process a queue or fire events.
   * Great option for backend workers.
   * @return {Boolean} True by default.
   */
  guard: async => {
    return true
  },
  process: async job => {
    // process queue
  },
  onCompleted: async job => {
    // do something when completed
  },
  onRemoved: async job => {
    // do something when job removed
  },
  onError: async err => {
    // do something on error like Redis connection failure etc.
  },
  onFailed: async (job, err) => {
    // do something when process fails
  },
};

You can define queues with options:

module.exports = {
  queueName: 'my-queue',
  process: {
    name: 'my-super-queue',
    concurrency: 1,
    processor: (job, done) => {
      // do something...
      done();
    }
  }
};

Adding jobs to a queue:

// api/controllers/someController.js
module.exports = {
  someAction: function(req, res) {
    sails.hooks.bulljs.myQueue.add({
        param: 'value'
    })
  }
};
