Multiple Cron Triggers
Set multiple Cron Triggers on three different schedules.
export default { async scheduled(event, env, ctx) { // Write code for updating your API switch (event.cron) { case "*/3 * * * *": // Every three minutes await updateAPI(); break; case "*/10 * * * *": // Every ten minutes await updateAPI2(); break; case "*/45 * * * *": // Every forty-five minutes await updateAPI3(); break; } console.log("cron processed"); },
};
interface Env {}
export default { async scheduled(controller: ScheduledController, env: Env, ctx: ExecutionContext) { // Write code for updating your API switch (controller.cron) { case "*/3 * * * *": // Every three minutes await updateAPI(); break; case "*/10 * * * *": // Every ten minutes await updateAPI2(); break; case "*/45 * * * *": // Every forty-five minutes await updateAPI3(); break; } console.log("cron processed"); },
};
Test Cron Triggers using Wrangler
The recommended way of testing Cron Triggers is using Wrangler.
Cron Triggers can be tested using Wrangler by passing in the --test-scheduled flag to wrangler dev. This will expose a /__scheduled route which can be used to test using a HTTP request. To simulate different cron patterns, a cron query parameter can be passed in.
$ npx wrangler dev --test-scheduled
$ curl "http://localhost:8787/__scheduled?cron=*%2F3+*+*+*+*"
