scheduler module

Run delayed or repeated callbacks inside the sandbox. Use named functions only.

Overview

scheduler lets you set timeouts and intervals during a parser session. Keep callbacks short and idempotent.

Long intervals may be cut short when the session ends.

API

setTimeout(fn, ms), clearTimeout(id).
setInterval(fn, ms), clearInterval(id).

Examples

javascript

const scheduler = use("scheduler");

function ping() {
  ctx.reply("Ping after delay");
}

function main() {
  ctx.reply("Scheduling...");
  scheduler.setTimeout(ping, 1000);
}

javascript

const scheduler = use("scheduler");

function tick() {
  ctx.reply("tick");
}

function main() {
  scheduler.setInterval(tick, 2000);
  ctx.reply("Interval set (may stop when session ends)");
}
