What this skill does
Cloudflare Cron Triggers Status: Production Ready ✅ Last Updated: 2025-11-25 Dependencies: cloudflare-worker-base (for Worker setup) Latest Versions: wrangler@4.81.0, @cloudflare/workers-types@4.20260408.0 --- Quick Start (5 Minutes) 1. Add Scheduled Handler to Your Worker src/index.ts: Why this matters: Handler must be named exactly scheduled (not scheduledHandler or onScheduled) Must be exported in default export object Must use ES modules format (not Service Worker format) 2. Configure Cron Trigger in Wrangler wrangler.jsonc: CRITICAL: Cron expressions use 5 fields: minute hour day-of-month month day-of-week All times are UTC only (no timezone conversion) Changes take up to 15 minutes to propagate globally 3. Test Locally Testing tips: /scheduled endpoint is only available with --test-scheduled flag Can pass any cron expression in query parameter Python Workers use /cdn-cgi/handler/scheduled instead 4. Deploy After deployment: Changes may take up to 15 minutes to propagate Check dashboard: Workers & Pages > [Your Worker] > Cron Triggers View past executions in Logs tab --- When to Load References Load immediately when user mentions: cron-expressions-reference.md → "cron syntax", "schedule format", "expression", "minute hour day", "every X minutes" common-patterns.md → "examples", "use cases", "patterns", "real-world", "database cleanup", "report generation", "how to" integration-patterns.md → "implement", "Hono", "multiple triggers", "bindings", "workflows", "error handling" wrangler-config.md → "configuration", "wrangler.jsonc", "multiple crons", "environment-specific", "dev staging production" testing-guide.md → "test", "local development", "scheduled", "unit test", "curl", "debugging" Load proactively when: Building new scheduled task → Load integration-patterns.md Configuring wrangler.jsonc → Load wrangler-config.md Debugging cron expression → Load cron-expressions-reference.md Testing locally → Load testing-guide.md Looking for examples → Load common-pattern …
