## README

# Node.js Sleep()
for those who need Sleep() just like me.

![Sleeping Beauty](https://res.cloudinary.com/jochemstoel/image/upload/v1744663064/NPM/1744663021511-canvas.png)

*UPDATE: NO LONGER REQUIRES CHILD PROCESS, using deasync instead. It will fall back on self child process mode if deasync fails.*

```

 ```

* will make the system wait xxx milliseconds.
* can be used to delay script execution.
* is often used to relax the system in between resource intensive tasks.
* works on every platform x86 + x64 Windows / Linux / OSX



* Existing sleep() solutions use a blocking while loop which uses 100% CPU. This is incredibly stupid.
* Also, many sleep() solutions are only for Windows or only for Linux.

### Install using NPM
```bash
npm install system-sleep
```
### Use
```javascript
var sleep = require('system-sleep');

```
### Test
Prints <i><a>variable y</a></i> to the console every 1 second during 10 seconds.
```javascript
var sleep = require('system-sleep');
for (y = 0; y < 10; y++) {
	console.log(y);
	sleep(1000);
}
```
