Node.js — Clear Terminal / Console. Reset to initial state.

reset.js

console.reset = function () {
  return process.stdout.write('\033c');
}

work on ubuntu, node v5.10.0

P/s: or just simply console.log('\033c') will do

don't work in strict mode on node v6
But write("\x1B[2J") did

Thanks, it worked for me. don't forget to call the function

Node 5 strict mode requires this, which is the same as jimmywarting's answer but it also resets the cursor:

process.stdout.write('\x1B[2J\x1B[0f');

@DesignByOnyx Thanks man!

Sweet! Thanks.

Strict mode + Node.js all supported platforms:

'use strict';
process.stdout.write('\x1Bc');
// or
console.log('\x1Bc');

or you could use the key combinations Ctrl + L

Thank you @DesignByOnyx

process.stdout.write('\x1B[2J\x1B[0f\u001b[0;0H');

what is the '\x1Bc' it look like a regular expression, why does it clear the console

@TheRealCasadaro It's an ANSI Escape Sequence which clears the screen and buffer for the terminal output. It basically becomes <ESC>c which is the VT100 escape code for resetting the terminal.

The combinations Ctrl + L reset the full log.

thank you it works like a charm

Thank you @DesignByOnyx!

Works on my debian 8 :D

Works perfectly on Windows 10 Node.js v8.9.1.
Thanks.

Thank you @DesignByOnyx
It works on Windows 10 Node.js v.8.5

@SLeonescu Wow, thanks, that's so easy!

Thank you @TemaSM

or via package.json:

"scripts": {
+  "cls_opt1": "clear",
+  "cls_opt2": "node -e \"process.stdout.write('\\033c')\""
}

console.clear() does the trick without having to use keyboard shortcuts every time you run your js files

The below is better, because it clears also scroll-back buffer

process.stdout.write('\033c\033[3J');

ESC [ 3 J: erase whole display including scroll-back buffer (since Linux 3.0).

@DesignByOnyx's answer works on Ubuntu bash on Windows 10.

Thanks @ghost. For me Ctrl + L worked to clear node.js console.

work on MacOS Mojave

thanks

Thank you.
If anyone is wondering when/how to call the function, the following is working for me :

app.listen(process.env.PORT || 3000,function (){
  process.stdout.write('\033c'); 
}

since app.listen accepts a callback method, hope this helps someone ! :)

Thank you @TemaSM, its beautiful

Works on macOS Big Sur 😸
