bull-manager

Easily manage your bull queues

Getting started

$ yarn add bull-manager

Usage

On the worker side:

const {configureQueues, createJobQueue} = require('bull-manager')

configureQueues({
  isSubscriber: true,
  prefix: 'my-prefix',
  createRedis: type => {
    /* … */
  },
  onError: (job, error) => {
    console.error('An unexpected error happened')
  }
})

await createJobQueue('my-cool-job', job => {/* handler */}, {
  concurrency: 10,
  onError: (job, error) => {
    console.log('my cool job failed')
  }
}, {
  /* job options */
})

On the client side:

const {configureQueues, joinJobQueue, enqueue} = require('bull-manager')

configureQueues({
  prefix: 'my-prefix',
  createRedis: type => {
    /* … */
  },
  onError: (job, error) => {
    console.error('An unexpected error happened')
  }
})

await joinJobQueue('my-cool-job', {
  /* job options */
})

await enqueue('my-cool-job', 'job-name', {
  something: 'important'
}, {
  /* job options */
})

API

configureQueues(options)

Configure bull-manager by specifying the following options:

• isManager: set to true for workers. Defaults to false.
• createRedis: function that creates redis connections if you need custom options. Passing a function will enable connections reuse for subscriber and client connections. Defaults to undefined.
• onError: error handler that will be called for failed jobs when the corresponding queue doesn’t specify a custom error handler. Defaults to undefined.

createJobQueue(name, handler, options, jobOptions)

Create a job queue and add the corresponding handler.

It takes the following options:

• onError: specific error handler that will be called when a job fails. Throwing withing the onError handler will invoke the global error handler (when defined) with the thrown error. Defaults to undefined.
• concurrency: amount of concurrent jobs per process. Defaults to 1.

For jobOptions, refer to the bull documentation.

There is one additional job option:

• jobIdKey: enqueue will set the jobId to _.get(data, jobIdKey)

The default values are the same as in Queue#add except for removeOnComplete that will be true.

joinJobQueue(name, jobOptions)

Join a job queue. Behaves like createJobQueue except that it does not register a handler.

enqueue(name, jobTitle, data, jobOptions)

Add a job to the name jobQueue.

jobTitle is just a simple name to identify a job, it is not required. It will set name property to data if not set.

disconnectQueues()

Run Queue#disconnect on all queues.

Cool features

jobIdKey

Pass jobIdKey to job options so that enqueue will set the jobId to _.get(data, jobIdKey). Only works for createJobQueue and joinJobQueue job options, as it doesn’t make sense for enqueue. You always have the possibility to use jobId in enqueue, it will override anything else.

Fallthrough error handlers

Throwing in a job specific error handler will call the global error handler with that error.

Random things

• You don’t need to pass job options to createJobQueue if you are never going to use enqueue in your workers.
• removeOnComplete is set to true by default.
