#Alepha - Scheduler

#Installation

Part of the alepha package. Import from alepha/scheduler.

npm install alepha

#Overview

Cron tick engine used under $job. Not an application-facing API.

There is no scheduler primitive. Declare scheduled work with $job({ cron }) (alepha/api/jobs), which registers here and adds the things a bare tick lacks: run history, retries, timeouts and an admin view.

CronProvider remains the single registry of cron expressions — the the Cloudflare build reads it to emit native platform triggers. Register a cron directly with CronProvider.createCronJob() if you need a tick without a database.

Features:

  • Cron expression scheduling (e.g., 0 0 * * *)
  • Serverless cron dispatch via the serverless:cron hook (Cloudflare, generic)

For distributed locking and retries around scheduled work, use $job({ cron }) from alepha/api/jobs — it layers durability on top of this scheduler.
