Welcome to easy-sleep ⏱️

Add sleep(), usleep() to Node.js, via a C/C++ addons with N-API. implementation true event-loop blocking sleep.

Install using NPM

``
npm install easy-sleep -S
`

Usage

$3

implementation based on Promise + setTimeout combination.

`js
const { sleep } = require('easy-sleep');

async function test() {
console.log(1);
await sleep(3000); // 3000 ms delay
console.log(2); // Output 2 after about 3000 milliseconds
}
`

$3

true event-loop blocking sleep. use caution in the main thread.

* Thread.sleep(n): sleep for n milliseconds
* Thread.usleep(n): sleep for n microseconds (1 second is 1000000 microseconds)
* Thread.wait(n): implementation based on Atomics.wait (Support Node.js v8.10.0+)

`js
const { Thread } = require('easy-sleep');
Thread.sleep();
`

You can use in worker thread.

`js
// app.js
const { Worker } = require('worker_threads');
const list = ['A', 'B', 'C', 'D'];
for (const item of list) {
const worker = new Worker('./worker.js');
worker.on('message', msg => {
console.log(main thread callback message: ${msg});
worker.terminate()
});
worker.postMessage(item);
}
`

`js
// worker.js
const { parentPort, threadId } = require('worker_threads');
const { Thread } = require('easy-sleep');

parentPort.on('message', async data => {
console.log(worker thread(${threadId}) receive message: ${JSON.stringify(data)});
Thread.sleep(3000 + threadId * 1000);
parentPort.postMessage(worker(${threadId}));
});
