Testing Cloudflare Cron Triggers Locally for Push Notification Workflows

This article is an English translation of the original Japanese article.

I use Cloudflare Workers Cron Triggers to send push notifications on the morning of practice days. The challenge was figuring out how to verify the entire workflow locally without waiting for the scheduled cron time.

In my implementation, I separate the Worker's scheduled event from the HTTP route that handles the notification logic.

Keep the scheduled handler thin

The Worker receives the cron event and calls an internal route handler.
