使用公牛和 typescript 进行作业调度

Question

I am trying to do some scheduling using bull . Here is my code

const avqueue = new Bull('avque');

avqueue.add({ video: '' }, { repeat: { cron: '*/50 * * * * *' }} );

avqueue.process( function(job, done) {
  console.log('avqueue');
  done();
});

But it is getting executed in every milliseconds.Please let me know if I miss any param or someting.

Answer 1

You did a mistake on the cron configuration.

cron: '*/50 * * * * *' is an invalid configuration

---

The cron configuration only support 5 elements and not 6.

The correct configuration is :

cron: '*/50 * * * *'

In this bull guide you can see the following example:

// Repeat every 10 seconds for 100 times.
const myJob = await myqueue.add(
  { foo: 'bar' },
  {
    repeat: {
      every: 10000,
      limit: 100
    }
  }
);

// Repeat payment job once every day at 3:15 (am)
paymentsQueue.add(paymentsData, { repeat: { cron: '15 3 * * *' } });
