To offload time-consuming tasks (email sending, image processing, report generation) from the main HTTP request-response cycle using Redis-based queues. Use when: When an API request takes longer than a few seconds; To handle rate-limited 3rd party API calls; To retry failed operations automatically.

- To offload time-consuming tasks (email sending, image processing, report generation) from the main HTTP request-response cycle using Redis-based queues. Use when: When an API request takes longer than a few seconds; To handle rate-limited 3rd party API calls; To retry failed operations automatically.
Purpose
To offload time-consuming tasks (email sending, image processing, report generation) from the main HTTP request-response cycle using Redis-based queues.
When to Use
- When an API request takes longer than a few seconds.
- To handle rate-limited 3rd party API calls.
- To retry failed operations automatically.
Procedure
1. Setup
Requires a running Redis instance.
npm install bullmq ioredis
2. Producer (Adding Jobs)
Add jobs to a queue.
const { Queue } = require('bullmq');
const emailQueue = new Queue('email-queue', { connection: redisConnection });
async function sendWelcomeEmail(user) {
await emailQueue.add('welcome-email', {
email: user.email,
name: user.name
}, {
attempts: 3, // Retry 3 times on failure
backoff: { type: 'exponential', delay: 1000 }
});
}
3. Consumer (Processing Jobs)
Worker processes jobs from the queue. Run this in a separate process or service.
const { Worker } = require('bullmq');
const worker = new Worker('email-queue', async job => {
console.log(`Sending email to ${job.data.email}`);
await sendEmailService(job.data);
}, { connection: redisConnection });
worker.on('completed', job => {
console.log(`Job ${job.id} completed`);
});
worker.on('failed', (job, err) => {
console.log(`Job ${job.id} failed: ${err.message}`);
});
Constraints
- Redis Dependency: The queue relies entirely on Redis. If Redis goes down, queues are inaccessible (though data persists if configured).
- Concurrency: Configure
concurrencyoption in Worker to process multiple jobs in parallel based on CPU resources.
Expected Output
Improved API response times (immediate 202 Accepted) and reliable background task execution with retry mechanisms.
