Pad String

This project creates a NPM module to help faciliting addition of string paddings to extend a string to a certain length.

Install

npm install pad-string --save

Then in your code, import the function you would like to use:

import { padStart, padEnd, padBothEnds } from 'pad-string'
var str1 = padStart('test', 10)         // str1 = '      test'
var str2 = padEnd('test', 10, 'er')     // str2 = 'testererer'
var str3 = padBothEnds('test', 10, 'a') // str3 = 'aaatestaaa'

How to use it

The package provides 3 functions: padStart(targetString, targetLength[, fillerString]), padEnd(targetString, targetLength[, fillerString]), and padBothEnds(targetString, targetLength[, fillerString]).

• targetString: input string to add padding to.
• targetLength: the final length the string will be padded to. If this length is smaller or equal to the target string length, then we will return the target string.
• fillerString (optional): the string to fill the padding. If provided, the filler string will repeat itself until padding the target string to the target length; if not provided, the padding will be filled with white space.
