String-padding

Padding strings in node.

Installation

$ npm install string-padding

Usage

var pad = require('string-padding');
pad(string [, length [, padding [, side ]]]);

• string: A string of text of any length.
• length (optional): The length the output string should be. It doesn’t truncate the original string.
• padding (optional): The character(s) for padding. You can go crazy with multiple characters ;)
• side (optional): The side which should be padded; pad.LEFT, pad.RIGHT or pad.BOTH.

Extending core String object

For those who are fine with extending the core String object, you can do just that. Note you can skip the first parameter and directly call .pad() on a string.

var pad = require('string-padding');
String.prototype.pad = pad.prototype;
 
'Hello World!'.pad(16, '0'); // 0000Hello World!

Happy padding! :)
