Bull is a powerful Node.js library for handling distributed job queues with Redis, enabling reliable background task processing. As the creator of CoreUI with over 10 years of Node.js experience since 2014, I’ve used Bull for email sending, image processing, report generation, and scheduled tasks in production systems. The standard approach creates queue instances, adds jobs with data, and processes them with worker functions that run asynchronously. This provides robust job handling with retries, priorities, and delayed execution.
