Multiple Cron Triggers

JavaScript

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");
  },
};

TypeScript

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+*+*+*+*"
