Queues, workers and background jobs for nuxt

Features

  • Create queues and workers based on bullmq
  • Create scheduled tasks
  • UI for managing jobs
  • Autoscan and initialize queues automatically
  • Dynamically create new queues and workers
  • Ability to integrate with external queues and workers

Quick Setup

  1. Add nuxt-concierge dependency to your project
# Using pnpm
pnpm add -D nuxt-concierge

# Using yarn
yarn add --dev nuxt-concierge

# Using npm
npm install --save-dev nuxt-concierge
  1. Add nuxt-concierge to the modules section of nuxt.config.ts
export default defineNuxtConfig({
  modules: ["nuxt-concierge"],
  concierge: {
    redis: {
      host: "localhost",
      port: 6379,
      password: "",
    },
  },
});

Use the redis option to configure the redis connection, or use the redis environment variables:

NUXT_REDIS_HOST='localhost'
NUXT_REDIS_PORT=6379
NUXT_REDIS_PASSWORD=''

Note: A redis connetion is required for this module to work.

Usage

Creating Queues

There are two ways to create queues.

  1. Inline using options

We call this Simple Queues because only a queue name is needed. To create a simple queue:

concierge: {
  queues: ["SendEmail"],
},
  1. The second method for creating queues is by defining it using defineQueue.

For example:

/concierge/queues/my-queue.ts:

import { defineQueue } from "#concierge-handlers";

export default defineQueue("SendEmail", {
  defaultJobOptions: {
    removeOnComplete: true,
    removeOnFail: true,
  },
});

NOTE: your queue must be created in the /concierge/queues folder

The second parameter gives you full control over the queue behavior

Creating Workers

For jobs to be processed at least one worker is required. Workers don't have to necessarily be running in a nuxt, but if you want to manage workers in nuxt, you can create one using defineWorker

For example:

/concierge/workers/my-worker.ts:

import { defineWorker } from "#concierge-handlers";

export default defineWorker("SendEmail", async (job) => {
  const { to } = job.data;

  // send customer email
});

Workers defined this way will automatically be started during application startup

NOTE: your workers must be created in the /concierge/workers folder

Creating CRON Jobs

Cron jobs can be created using the defineCron helper.

For example:

/concierge/cron/daily-report.ts:

import { defineCron } from "#concierge-handlers";

export default defineCron(
  "DailySalesReport",
  async () => {
    // Run a daily report
  },
  {
    every: 43200000, // 12 hours
    immediately: true,
  }
);

Cron jobs are placed in a special queue called CRON. This queue is automatically created for you.

NOTE: your cron must be created in the /concierge/cron folder

Accessing queues

To access queues, a getQueue helper is provided.

import { $useConcierge } from "#concierge";

export default defineEventHandler(async (event) => {
  const { getQueue } = $useConcierge();
  const emailQueue = getQueue("SendEmail");

  await emailQueue.add("sendWelcomeEmail", { to: "[email protected]" });

  return true;
});

This would add a job to the queue and will be processed by the worker.

Queue Management UI

The Concierge dashboard can be accessed at:

http://localhost:3000/\_concierge/

FAQ

  1. Does this work in a serverless environment?

Yes and no, but mostly no. Serverless environments typically have a timeout, so workers will not be able to run in the backgorund to reliably process jobs. If you want to use this module in a serverless environment, I recommend to deploy your workers elsewhere, and just reference the queues in this module. This way you can still leverage the other features, like queue management, and ui.

  1. Can I disable the Queue management UI in production?

The management UI is already disabled by default in production. If you want't to enable it in production, you must enable it explicitly in the options:

export default defineNuxtConfig({
  concierge: {
    redis: {
      host: "...",
    },
    managementUI: true,
  },
});
  1. Can I password protect the Queue management UI?

Auth for the UI is out of scope of this module, but it can easily be done using the Nuxt Security
