How do I use Bull for job scheduling in Node.js?

What is Bull and how can I use it for job scheduling?

Bull is a Node.js library for handling distributed jobs and messages in a queue. You can use it to schedule jobs efficiently.

Can you show me a basic example of how to set it up?

Sure! First, install Bull using npm: npm install bull. Then, create a queue and add jobs to it like this: const Queue = require('bull'); const myQueue = new Queue('my-queue'); myQueue.add({ data: 'myData' });.

How do I process the jobs that I add to the queue?

You can process jobs by defining a process function: myQueue.process(async (job) => { console.log(job.data); }); This will log the data of each job as it's processed.

What happens if a job fails?

If a job fails, Bull allows you to retry it automatically or handle the failure with custom logic. You can set options like attempts when adding a job.
