sleep is a command in Unix-like operating systems that suspends program execution for specified time. This package provides both a synchronous and an asynchronous method for sleeping without doing a busy wait. The synchronous sleep is achieved using Atomics.wait() (1), and the asynchronous one is achived using Promisified setTimeout().
This package also provides a command line tool xsleep -- with a similar behaviour as sleep -- that can be used to sleep for specified time in seconds, minutes, hours, or days. Please check examples below. It should be noted small delays (few milliseconds) are not accurate.
import {sleep, sleepSync} from "jsr:@nodef/extra-sleep";
console.log('Turn on Alarm');
await sleep(1000);
console.log('Turn on Shower');
sleepSync(1e+6); // And relax!# Install CLI tool
