What is the correct way to export a scheduled handler?

The handler must be named exactly 'scheduled' and must be part of the default export object in an ES module format.

How do I test scheduled workers on my local machine?

Run 'wrangler dev --test-scheduled' and use curl to hit the '/__scheduled' endpoint, passing your cron expression as a query parameter.

Why is my Cloudflare Cron Trigger not running immediately after deployment?

Changes to cron triggers in wrangler.jsonc can take up to 15 minutes to propagate globally across the Cloudflare network edge.

Does Cloudflare support local timezones for cron schedules?

No, Cloudflare Cron Triggers execute on UTC time only. You must manually convert your local time to UTC when defining the expression.

What is the benefit of enabling Green Compute for crons?

Green Compute routes your cron executions to data centers powered by renewable energy, reducing your application's carbon footprint at no additional cost.

Cloud Infrastructure

Streamlines the implementation and testing of scheduled tasks and cron-triggered jobs within Cloudflare Workers.

About

This skill provides production-ready guidance for implementing Cloudflare Cron Triggers, ensuring scheduled tasks are configured correctly to avoid common pitfalls like UTC timezone confusion and handler naming errors. It offers domain-specific implementation patterns, including standalone workers, Hono integrations, and complex multi-trigger workflows. By providing precise instructions for local testing with Wrangler and best practices for Green Compute and error handling, this skill helps developers build reliable, periodic background processes on the Cloudflare edge.

Key Features

Advanced integration patterns for D1, KV, R2, and multi-step Workflows.
Critical troubleshooting for propagation delays and UTC-only timezone management.
Step-by-step local testing workflows using the wrangler --test-scheduled flag.
21 GitHub stars
Standardized boilerplate for the required 'scheduled' handler and ES module exports.
Comprehensive reference for 5-field cron syntax and common scheduling patterns.

Use Cases

Automating periodic database maintenance, cleanup, and synchronization tasks.
Orchestrating complex, time-based backend processes and workflow triggers.
Generating and distributing scheduled reports, analytics, or automated notifications.
