Introduction

adonis-resque add the queue ability to adonis base on node-resque. Resque is a background job system backed by Redis.

Installation

node ace add adonis-resque

[!IMPORTANT] adonis-redis is required for resque redis connection.

Folders

Jobs default place in folder app/jobs. You can import the job by sub-path.

import Example from #jobs/example

[!TIP] Please follow this instruction: The sub-path imports.

Both package.json and tsconfig.json are required to add the job path:

• add to package.json

"#jobs/*": "./app/jobs/*.js"

• add to field compilerOptions.paths in tsconfig.json

"#jobs/*": ["./app/jobs/*.js"]

Job Usage

You can create a resque job by adonis command: node ace make:job <YourJobName>

Basic

Create a basic example job: node ace make:job BasicExample. Every job has a perform method. It runs in the background, which consumer from the node-resque queue.

import { BaseJob } from 'adonis-resque'
export default class BasicExample extends BaseJob {
  async perform(name: string) {
    this.logger.info(`Hello ${name}`)
  }
}

Now you can enqueue this job.

import BasicExample from '#jobs/basic_example'
await BasicExample.enqueue('Bob')

Console would print Hello Bob.

[!WARNING] Make sure your Job ClassName is unique in the queue. and argument of method perform would be jsonify to redis.

Batch enqueue

await BasicExample.enqueueAll([
  ['Alice'],
  ['Bob'],
  ['Carol'],
  ['Dave'],
  ['Eve']
])

Delayed enqueue

const oneSecondLater = 1000
await BasicExample.enqueue('Bob').in(oneSecondLater)

Or enqueue at a specify timestamp

const fiveSecondsLater = new Date().getTime() + 5000
await BasicExample.enqueue('Bob').at(fiveSecondsLater)

Repeated Enqueue

class Job has the schedule properties.

• interval, .e.g 5s, 15m, 2h and 1d. package ms for more details.
• cron, for cron syntax, look up the croner package

The example below enqueue in both every 1 second and 5 minutes, since it's cron/interval settings.

export default class BasicExample extends BaseJob {
  // enqueue job cronly
  cron: '*/1 * * * * *',
  // enqueue every five minutes
  interval: '5m',
  async perform(name: string) {
    this.logger.log(`Hello ${name}`)
  }
}

[!TIP] You can and should run multi process schedules. Not all schedules will enquene the cron job, only the leader do, even in the different machines.
For more informations, see node-resque leader scheduler: https://github.com/actionhero/node-resque?tab=readme-ov-file#job-schedules

Node-Resque Plugin

Adonis-resque encapsulated the default node-resque plugins in a smooth way, with the better typing support.

The default node-resque plugins are:

• Retry
• JobLock
• Retry
• QueueLock
• DelayQueueLock
• Noop

You can adding them to the plugins property of your job class, by Plugin.<PluginName>({...pluginOptions})

Plugin.jobLock

JobLock plugin is used to prevent a job to be performed (hook in beforePerform), which has the same name, queue and args is already running.

If reEnqueue is true, the job will be put back (re-enqueue) with a delay .

import { BaseJob, Plugin } from "adonis-resque"

export default class ExampleJob extends BaseJob {
    plugins = [
        Plugin.jobLock({ reEnqueue: false, enqueueTimeout: 3000 })
    ]
    async perform() {
        this.logger.info('Example job started')
        await sleep(60000)
        this.logger.info('Example job done')
    }
}

function sleep(ms: number) {
    return new Promise(resolve => setTimeout(resolve, ms));
}

Plugin.queueLock

Similar to jobLock, but it would be prevented before enqueue. If a job with the same name, queue, and args is already in the queue, do not enqueue it again.

QueueLock Options:

export interface QueueLockOptions {
    /**
     * in seconds
     */
    lockTimeout?: number
    key?: LockKey
}

Plugin.delayQueueLock

Same as queueLock, but it is for the delay queue.

Plugin.retry

If a job fails, retry it times before finally placing it into the failed queue You can specify the retryDelay option to delay, or set the backoffStrategy to the delay ms array. Note: It will retry by key, composed of queueName, jobName and args. Not retry by the enqueuing action.

import { BaseJob, Plugin } from "adonis-resque"

export default class ExampleJob extends BaseJob {
    plugins = [
        Plugin.retry({
            retryLimit: 3,
            backoffStrategy: [1000, 3000, 8000]
        })
    ]
    async perform() {
        const res = await fetch(`https://dummyjson.com/products/1`)
        this.logger.info(`Response status is ${res.status}`)
    }
}

Plugin.noop

you can customize the error logger by option logger

Custom Your Own Plugin

You can create your own plugin by extending the BasePlugin class, it also implements the Plugin abstract class from node-resque. See more details in node-resque plugins.

import { BasePlugin } from "adonis-resque"
export default class MyPlugin extends BasePlugin {
    /**
     * Plugin options here
     * with default values
     */
    options = {
        foo: 'bar'
    }
    async beforeEnqueue() {
    }
    async afterEnqueue() {
    }
    async beforePerform(){
    }
    async afterPerform() {
    }
}

Now you can use it in your job class:

import { BaseJob } from "adonis-resque"
// import MyPlugin from './my-plugin'

class ExampleJob extends BaseJob {
    plugins = [
        MyPlugin.create({ foo: 'baz' })
    ]
}

Handle Failure Jobs

You can handle failure jobs by defining a onFailure method to your job class. Once a job fails, before it is moved to the failed queue, this method will be called.

import { BaseJob, type ResqueFailure } from 'adonis-resque'
class Job extends BaseJob {
      async onFailure(failure: ResqueFailure) {
        console.log('resque job failured:', failure)
    }
}

The ResqueFailure interface is:

export interface ResqueFailure {
    // Only the failure emitted by MultiWorker has a workerId
    workerId?: number
    queue: string
    job: NodeResqueJob
    failure: Error
    duration: number
}

[!TIPS] If you are using retry plugin, the onFailure method will be called only if the job has exceeded the retry limit.

Failure Event

Another way to handle failure jobs is to listen to the resque:failure event.

go start/events.ts to handle.

import emitter from '@adonisjs/core/services/emitter'

emitter.on('resque:failure', (failure) => {
    console.error('resque:failure', failure)
})

Demonstration

Send Mail Job

In Adonis Documentation, they use bullmq as mail queueing example. But if we wanna use adonis-resque for mail.sendLater, how to do?

1. Create a Mail Job
   Run node ace make:job Mail to create the mail job, then edit it in app/jobs/mail.ts

import { BaseJob } from 'adonis-resque'
import mail from '@adonisjs/mail/services/main'
import { MessageBodyTemplates, NodeMailerMessage } from '@adonisjs/mail/types'

interface Options {
    mailMessage: {
        message: NodeMailerMessage;
        views: MessageBodyTemplates;
    }
    config: any
}
export default class Mail extends BaseJob {
    async perform(option: Options) {
        const { messageId } = await mail.use('smtp')
            .sendCompiled(option.mailMessage, option.config)
        this.logger.info(`Email sent, id is ${messageId}`)
    }
}

2. Custom mail.setMessenger in a service provider
   You can add the below code snippet to a boot method of any service provider.

const mail = await this.app.container.make('mail.manager')
mail.setMessenger(() => {
  return {
    async queue(mailMessage, sendConfig) {
      return Mail.enqueue({ mailMessage, config: sendConfig })
    }
  }
})

3. mail.sendLater is available now! Try it:

await mail.sendLater((message) => {
  message.to('[e-mail]', 'Your Name')
  .subject('Hello from adonis-resque')
  .html(`<strong>Congratulations!</strong>`)
})

[!CAUTION] You should insure @adonisjs/mail has a correct config, you'd better to test it first.

Configuration

Here is an example of config/resque.ts

{
    /**
     * redis connection config from @adonisjs/redis
     */
    redisConnection: 'main',
    /**
     * run web & worker in same process, if enabled
     * You need to run command node ace resque:start if it is turned off
     *
     * it's convenient but NOT Recommanded in production
     * also, DO NOT enable for math-heavy jobs, even in the dev or staging environment.
     * 
     */
    runWorkerInWebEnv: true,
    /**
     * when runScheduler enabled, it starts with worker
     * if you'd like to run scheduler in the separated processes
     * please turn runScheduler off, and run command
     * node ace resque:start --scheduler
     */
    runScheduler: true,
    /**
     * enable node-resque multiworker
     * @docs https://github.com/actionhero/node-resque?tab=readme-ov-file#multi-worker
     */
    isMultiWorkerEnabled: true,
    /**
     * the first argument in MultiWorker constructor
     */
    multiWorkerOption: {
        minTaskProcessors: 1,
        maxTaskProcessors: 10
    },
    /**
     * the argument for Worker constructor, if multiWorker is not enabled
     */
    workerOption: {
    },
    /**
     * the default queue name for jobs to enqueue
     */
    queueNameForJobs: 'default',
    /**
     * queue name for workers to listen,
     * is a string or an array of string
     * setting a proper queue name could change their priorities 
     * e.g. queueNameForWorkers: "high-priority, medium-priority, low-priority"
     * All the jobs in high-priority will be worked before any of the jobs in the other queues. 
     */
    queueNameForWorkers: '*',
    queueNameForWorkers: '*',
    /**
     * set null to use the default logger
     */
    logger: null,
    // verbose mode for debugging
    verbose: true
}

Web UI

node-resque also compatible with some Resque Web UI, .e.g resque-web

Here is docker-compose.yml an example

services:
  redis:
    image: redis
  resque-web:
    image: appwrite/resque-web:1.1.0
    ports:
      - "5678:5678"
    environment:
      - RESQUE_WEB_HOST=redis # (OPTIONAL - Use only if different than the default 127.0.0.1)
      - RESQUE_WEB_PORT=6379  # (OPTIONAL - Use only if different the default 6379)
      - RESQUE_WEB_HTTP_BASIC_AUTH_USER= # (OPTIONAL - if not set no password used)
      - RESQUE_WEB_HTTP_BASIC_AUTH_PASSWORD=  # (OPTIONAL - if not set no password used)
    depends_on:
      - redis
    restart: unless-stopped

Notice for the graceful exit

resque require the graceful exit, or schedulers would waiting for a leader election.

node-resque may not exit in dev environment if you exit by ctrl+c. you can change bin/server.ts

app.listenIf(app.managedByPm2, 'SIGINT', () => app.terminate())

to

app.listen('SIGINT', () => app.terminate())

if adonis dev server terminated but process still there, you can send SIGTERM signal to all node process(on macOS) killall node

You can also check the redis key resque:resque_scheduler_leader_lock, which value is scheduler name contains pid of the leader process. it should be release once server terminated.
