Create a scheduled (cron) Netlify Function

Documented steps

1. Write a function in netlify/functions/, e.g. my-job.mts: export default async (req) => { const { next_run } = await req.json(); console.log('next run', next_run); }.
2. Declare the schedule in code (TypeScript/JavaScript only): export const config = { schedule: "@hourly" } — accepts @yearly/@monthly/@weekly/@daily/@hourly or full cron syntax like "0 0 * * *" (UTC).
3. Alternatively declare it in netlify.toml: [functions."my-job"] schedule = "@daily" (function name without extension).
4. Test locally: netlify dev plus 'netlify functions:invoke my-job' — schedules do not fire automatically in local dev.
5. Deploy to production. Verify runs in the Netlify UI function logs.
