node:timers

Node.js timers module, resolvable via both ESM import and CommonJS require. It re-exports the runtime's timer globals as named bindings.

Export	Description
`setTimeout` / `clearTimeout`	Schedule / cancel a one-shot callback.
`setInterval` / `clearInterval`	Schedule / cancel a repeating callback.
`setImmediate` / `clearImmediate`	Schedule / cancel a callback for the next loop iteration.

These are the same functions installed as globals (see Timers). The legacy active() / unenroll() helpers are intentionally omitted.

node:timers/promises

The node:timers/promises submodule provides Promise-based timers.

Export	Description
`setTimeout(delay?, value?, options?)`	Resolves with `value` after `delay` ms; honours `options.signal` (`AbortSignal`).
`setImmediate(value?, options?)`	Resolves with `value` on the next loop iteration; honours `options.signal`.
`setInterval(delay?, value?, options?)`	Returns an async iterator that yields once per interval.
`scheduler`	`scheduler.wait(delay, options?)` and `scheduler.yield()`.

javascript

import { setTimeout as sleep } from "node:timers/promises";
await sleep(100);
