#Overview

Cloudflare Workers cron provider.

This provider handles scheduled events from Cloudflare Workers Cron Triggers. Unlike the Node.js CronProvider, this doesn't use intervals/timeouts - instead, it reacts to scheduled events triggered by Cloudflare.

Usage:

  1. Define schedulers with $scheduler({ cron: "0 * * * *", handler: ... })
  2. Build your app with alepha build - cron triggers are automatically added to wrangler.jsonc
  3. Deploy to Cloudflare Workers

How it works:

  • During build, all registered $scheduler cron expressions are collected
  • The build generates wrangler.jsonc with triggers.crons automatically filled
  • When Cloudflare fires a cron trigger, the scheduled handler emits cloudflare:scheduled
  • This provider listens to that event and runs matching schedulers
