Add sleep() and usleep() to nodejs
npm install sleep


sleep
=====
Add [sleep()][1], msleep() and [usleep()][2] to Node.js, via a C++ binding.
This is mainly useful for debugging.
Note that because this is a C++ module, it will need to be built on the system you are going to use it on.
These calls will block execution of all JavaScript by halting Node.js' event loop!
==================================================================================
Alternative
-----------
When using nodejs 9.3 or higher it's better to use Atomics.wait which doesn't require compiling this C++
module.
The sleep and msleep functions can be implemented like this:
``js`
function msleep(n) {
Atomics.wait(new Int32Array(new SharedArrayBuffer(4)), 0, 0, n);
}
function sleep(n) {
msleep(n*1000);
}usleep
If you require this module is still required.
Usage
-----
var sleep = require('sleep');
* sleep.sleep(n): sleep for n secondssleep.msleep(n)
* : sleep for n milisecondssleep.usleep(n)
* : sleep for n` microseconds (1 second is 1000000 microseconds)
