How to gracefully shutdown bullmq when running inside an express server?

Asked 2022-Feb-18 at 08:11

I have an express app which uses bullmq queues, schedulers and workers. Even after pressing Ctrl + C I can still see the node process running inside my Activity manager but my server on the terminal shuts down. I know this because the bullmq task starts outputting console.log statements even after the server is down to the terminal.

This is what my server.js file looks like

You have to call the close() method on the workers:

Does MikroORM require a RequestContext when used with background workers like BullMQ?

Asked 2021-Dec-03 at 13:54

I'm using MikroORM with BullMQ workers. When MikroORM is used with Express apps, it requires a RequestContext in order to maintain unique identity maps for each request. I suspect the same is required when processing multiple jobs with the same BullMQ worker.

Has anyone else successfully combined these two libraries? Is it possible to automatically fork the Entity Manager when a worker starts a new job?

...

ANSWER

Answered 2021-Dec-03 at 13:54

You can use @UseRequestContext() decorator for such cases. It will basically act as if the method would be executed after a middleware that adds the context. Note that to use it, this.orm needs to be the MikroORM instance.

QUESTION

Bull job is not stalled when processor terminated only when getting back up

Asked 2021-Oct-25 at 14:58

the code that I'm talking about is the repro code linked below

I have 2 "states" in the code (both of them are listening to queue global events):

Add a single message
Listen to messages

For some reason, Bull job is not reported as stalled when the listener worker is terminated only when the worker is back up.

although it should as stated in the docs:

I am afraid this works as designed, since in Bull the workers are also responsible of detecting stalled jobs, while in BullMQ you have the QueueScheduler that takes care of this.

QUESTION

Trigger the execution of a function if any condition is met

Asked 2021-Oct-08 at 03:03

I'm writing an HTTP API with expressjs in Node.js and here is what I'm trying to achieve:

I have a regular task that I would like to run regularly, approx every minute. This task is implemented with an async function named task.
In reaction to a call in my API I would like to have that task called immediately as well
Two executions of the task function must not be concurrent. Each execution should run to completion before another execution is started.

The code looks like this:

Heroku Redis gets a wrong version number error in logs

Asked 2021-Apr-07 at 11:34

I am using Heroku's Redis add-on. I upgraded yesterday to a higher tier and now I'm getting this when I send requests to my server. Any suggestions on what this error log means?

ANSWER

Heroku shipped new updates related to Redis as outlined in their changelog here: https://devcenter.heroku.com/changelog-items/1952.

The New Redis addons without a version specified will now default to 6.0 version, as it is secured with the self-signed certificate because of its built-in TLS for production plans. You'll need to add ssl_params: { verify_mode: OpenSSL::SSL::VERIFY_NONE } to handle the self-signed certificate. Please refer here for additional details: https://devcenter.heroku.com/articles/securing-heroku-redis

You may also work around this behavior by downgrading to Redis 5 version. You can do it by running(using --version flag): heroku addons:create heroku-redis:premium-2 --version 5 -a . More details here: https://devcenter.heroku.com/articles/heroku-redis#version-support-and-legacy-infrastructure.

BullMQ start Job from file with IIFE

ANSWER

Answered 2021-Feb-16 at 09:24

I have found a relative example in BullMQ docs. Actually, it's called sandbox processors, and only Bull and BullMQ, among any others job queue managers support such feature.

Other, you'll need to write your own implementation.

The alternative is using pm2 programmatic API which would manage files manually. In that case, you pass a direct path to file with IIFE, and then it has been executed via pm2.
