What is @types/bull?
@types/bull provides TypeScript definitions for the Bull package, which is a popular library for handling distributed job queues in Node.js applications.
What are @types/bull's main functionalities?
Creating a Queue
This feature allows you to create a new queue instance. The queue can then be used to add jobs and process them.
const Queue = require('bull');
const myQueue = new Queue('my-queue');
Adding Jobs to the Queue
This feature allows you to add jobs to the queue. Each job can contain data that will be processed by the worker.
myQueue.add({ foo: 'bar' });
Processing Jobs
This feature allows you to define a processor function that will handle the jobs added to the queue. The processor function can be asynchronous.
myQueue.process(async (job) => {
console.log(job.data);
});
Job Events
This feature allows you to listen to various job events such as 'completed', 'failed', etc. This can be useful for logging or triggering other actions based on job status.
myQueue.on('completed', (job, result) => {
console.log(`Job completed with result ${result}`);
});
