@jitesoft/random-string

Random string generator with a shared api for both node and web.

Usage:

import random from '@jitesoft/random-string';
const randomString = random(128, { minSpecial: 5 }); 
console.log(randomString);
// random string with a minimum of 5 special characters and a full length of 128 characters.

If you wish to access the specific files by absolute paths, they are located at @jitesoft/random-string/dist/index.node.js and @jitesoft/random-string/dist/index.web.js.

Information

Randomness

The random generator for the node version uses the crypto library to generate random characters while the web version uses the web crypto api. If web crypto api is not available, it will fallback to using the Math.random function.
The Math.random function is NOT a cryptographically secure algorithm, the randomness should be good enough, but do not use the fallback in cases where high security is a must.

Characters

The following characters are used (char codes):

Alpha: 65-90 & 97-122
Numbers: 48-57
Special: 33-47 & 58-64 & 91-96 & 123-126

Options

The following options (with defaults shown) can be passed as an object as the second argument of the function:

{
    "special": true,
    "numbers": true,   
    "alpha": true,
    "minSpecial": 0,
    "minNumbers": 0,
    "minAlpha": 0
}

This allows for a bit more specific generation of strings, default values are used for anything not set when parsing the options.

Source

The source code is kept intact under the src directory in the package. This is so that you may use the code directly if you wish to convert it with your own bundler or converter.
