DAY 60 OF MY MERN STACK JOURNEY
Backend Architecture & Background Jobs
Learning with
@Nannoyapp
WHAT I LEARNED:
■ Slow tasks like sending emails shouldn't block API responses.
■ Background jobs keep APIs fast by processing long-running tasks asynchronously.
■ BullMQ and Redis provide a reliable job queue for handling background work.
■ Workers process queued jobs independently from the main application.
WHAT I BUILT:
● Set up BullMQ with Redis for background job processing.
● Created an email queue and a dedicated worker process.
● Integrated job queuing into the user registration flow.
● Tested and verified the complete workflow in
@_reqit with a fast 202 Accepted response and successful background processing.
