simple-random v1.0.3

Simple Random

A simple flexible javascript library that creates random alpha-numeric strings. Very useful when creating random names for files, folders. Can also create secure random strings for temporary passwords and salts.

Works in both NodeJS and the browser.

###Secure Random if the secure option is set to true, we can create a random byte seed with a cryptography library as opposed to Math.random(). In Node we use the default crypto library. In webpack / browser versions we use the Web Cryptography API if supported.

##Installation

npm install simple-random --save 

##Usage ###Node

var sr = require('simple-random');
var randomString = sr(); // Generates a 16 character alpha-numeric string.
// Example output: "pnxTcl2nOBqTNFQR"

###WebPack

var sr=require('simple-random/browser'); 
var randomString = sr(); // Generates a 16 character alpha-numeric string.
// Example output: "pnxTcl2nOBqTNFQR"

###Browser

<script src="simple-random/dist/simple_random.js"></script>
<script>
var randomString = window.simpleRandom();

//Secure Random
var secureRandom;
if (simpleRandom.isSecureSupported){
  secureRandom = simpleRandom({secure:true})
}

</script>

##Options

• length: The length of the alpha-numeric string (default 16).
• digits: should allow digits in random string (default true).
• letters: should allow letters in random string (default true).
• caseSensitive: if set to false, only lowercase letter characters will be used (default true).
• secure: Whether or not to use the crypto library for secure random byte seed as opposed to Math.random() (default false).
• prefix: Prefix.
• suffix: Suffix.
• chars: A string containing all the characters to draw from, defaults to all alpha-numeric characters (overrides digits, letters and caseSensitive flags).
