@domusjs/cron — Introduction
The Cron Module in DomusJS provides a simple, pluggable scheduler to handle repetitive or timed tasks inside your backend application.
✅ Built on top of node-cron, it enables you to run background tasks at specific intervals, such as:
- Cleaning expired data.
- Synchronizing external services.
- Sending periodic reports.
- Triggering domain commands at regular times.
Why Use the Cron Module?
Section titled “Why Use the Cron Module?”In real-world applications, you often need to run logic outside the request/response cycle, such as:
| Scenario | Should Use Cron? |
|---|---|
| Run a task every hour | ✅ Yes |
| Perform cleanup once a day | ✅ Yes |
| Process thousands of items in the background | ❌ No (use jobs) |
| React to external events or publish/subscribe | ❌ No (use Event Bus) |
✅ The Cron Module is ideal for infrastructure-level automation where timing matters.
Benefits
Section titled “Benefits”✅ Pluggable & Modular → Register jobs only from the contexts that own them.
✅ Centralized Scheduler → Avoid duplicate or scattered scheduling logic.
✅ Integration-ready → Works smoothly with DomusJS Command Bus and other modules.
