Scheduler

Cron scheduling is powered by croner through src/core/utils/scheduler.ts, exposed via the facade:

import { cron } from "@/core/facade.ts";

cron.schedule("cleanup", "0 4 * * *", () => {
  console.log("daily cleanup");
});

API

Function	Description
cron.schedule(name, expression, fn, options?)	Register a named cron job. Returns a handle with only stop(). Re-scheduling the same name replaces the old job (and stops it). Options accept { timezone? }.
cron.stop()	Stop all registered cron jobs (called on app shutdown).

The returned handle's stop() also de-registers the job so it won't be stopped twice at shutdown.

Exposing the scheduler to a UI

Register a job in a controller + binding and report its state through a handler:

// controller: <module>.monitor.start
import { cron } from "@/core/facade.ts";

export const start = () => {
  let ticked = 0;
  const handle = cron.schedule("app.tick", "* * * * * *", () => { ticked += 1; });
  return { ok: true, name: "app.tick", expression: "* * * * * *", handle };
};

export const handlers = { start };

// UI
const result = await bindings["<module>.monitor.start"]();
// { ok: true, name: "app.tick", expression: "* * * * * *", ... }

The demo stops its own schedule before returning (job.stop()), leaving no dangling cron.
