在nest js中实现Bull Queue以在规范时间内发送通知？

Question

I'm developing an application in nestjs, which manages queues in the bull. I have a queue that want to send notification in particular time (read from db). How can I implement this?

Answer 1

Not sure you manage to find out how to implement this using bull, but let me share if someone also having the same query.

 import { Queue, QueueScheduler } from 'bullmq'; const myQueueScheduler = new QueueScheduler('Paint'); const myQueue = new Queue('Paint'); // Add a job that will be delayed at least 5 seconds. await myQueue.add('house', { color: 'white' }, { delay: 5000 });

you can use the delay while adding the item into the queue. With the delay bull only trigger the notification processor from the current time.

Ex: If you want to trigger notification after 1 hour you will calculate the millisecond delay based on the current time.
