I am also interested in background jobs for long-running tasks that the user doesn't need to wait for.

There is also this open source library https://trigger.dev. I saw it being used by this nextjs AI app called Midday.ai (https://github.com/midday-ai/midday) for e.g. syncing bank account data.

This could optionally go hand in hand with a toast progress bar, or perhaps a notification (bell) when the job is completed.

From the README:

"Bull is currently in maintenance mode, we are only fixing bugs. For new features check BullMQ, a modern rewritten implementation in Typescript. You are still very welcome to use Bull if it suits your needs, which is a safe, battle tested library."

So it would probably be better to use https://github.com/taskforcesh/bullmq.

Phat Tran are there specific use cases within the SaaS starter kit that you're thinking off, or is this for the implementation of your own product within it?

PS: by the way I'm just starting to develop a system which needs background tasks so I'm going to look into it. Thanks for putting this on my radar!
