Prioritizing Concurrent Requests: Queuing system to handle distributed processes and messages with NodeJS and Bull
To implement the solution with a queue, I used a package called 'Bull' (https://github.com/OptimalBits/bull). It's a library that helps with distributed job control, providing some very useful solutions for this type of work, such as background job processing, queues with priorities (FIFO, LIFO, and others), among other features. 'Bull' uses Redis for queue storage, so if your application crashes for any reason, once it's back online, it will continue executing the processes that are in the queue. In our case, we'll use the FIFO (First in, first out) queue solution, meaning priority based on arrival order.

How to use Job Queue to handle email sending in your Nestjs server
For Job Queue, NestJs provides a package named @nestjs/bull as an abstraction/wrapper on top of Bull, a popular, well-supported, high-performance Node. js-based Queue system implementation.

How do you handle queues in Node.js? Have you ever tried using pgboss?
I'm working on a large ETL project that involves handling queues for file integration. Currently, we are using Redis with Bull (https://www.npmjs.com/package/bull) for this purpose. However, to streamline our architecture and address security concerns, we are considering migrating the queue to PostgreSQL.

What is a good background scheduler?
BullMQ is a pretty solid choice: https://github.com/taskforcesh/bullmq It's the successor of Bull: https://github.com/OptimalBits/bull

Learning Guidance
For Node specifically, things like Streams, understanding the asynchronous model completely, and the event loop. Also, queues tend to get used a lot in Node, so understanding the basic concepts behind that and how to use something like bull would be useful.

image processing in express application, should it be done in a separate thread?
To do this properly, you need to put the task into queue, so if there are 1000 simultaneous uploads it won't kill your server but will be processed one by one. For the queue, see bull. Image hostings like AWS have some functionality for processing on their side, as an option.

How do I implement Heroku background processes?
This is a memory intensive process though and Heroku is OOM'ing with R14 errors. For this they recommend migrating intensive work like this to a Background Job via Redis, implemented in Bull and Throng

Next.js vs Node.js: A Modern Contrast
While many ways to write scalable Node.js applications exist, all narrow down to the underlying architecture. However, common hurdles in Node.js include serving static files, task scheduling, and utilizing available resources. To combat these, you can use a tactical approach. Because serving static assets with Node.js takes CPU time, a proxy content delivery network like CloudFront should help fix it. Recurring tasks need to fire events, which isn’t reliable with setTimeout or setInterval. As a solution, you can use a task scheduler framework like agenda.js. To handle resource utilization, you can use the cluster feature in Node.js, which listens to ports, accepts new connections, and distributes them across workers with built-in smarts to avoid overloading the process.

Scheduled tasks with multiple web servers
Agenda JS is an alternative to bull that uses MongoDB rather than redis. Not saying one is better than the other, just giving alternatives.
-
Using memory storage vs disk storage
If processing the file is going to take a relatively long time, you should send it to some asynchronous background process and immediately send a response to the user with status 202, then notify them later somehow if processing the file failed. Agenda is a good candidate for scheduling/managing more complex background tasks like this.

Need help developing auto logout feature
So I thought of 2 approaches, one using [agenda](https://github.com/agenda/agenda] and other using setTimeouts and storing the unique id for particular user in database. I am not sure which of the approach is scalable and maintainable in long run for thousands of users having daily activities.

Can someone explain the CommonJS require pattern used in the Agenda docs example project?
i think it would be helpful if you provided some links to what you're talking about. How on earth are we supposed to help without knowing which agenda package you're referring to? I went through the agenda github repo and not one of those files mentioned in your post even exists in that repo........
