About The Package

There are lots of scenarios which one can use our Random string generator the most known or the best scenario is for

1.Password generation

2.Token generation.

3.Testing

4.id generation

This package generate random string based on the given parameters.

Getting Started

To start to use this on local machine build then first Test the program using the test.js

Install node modules

• npm

npm install randomized-string

• yarn

yarn add randomized-string

Usage

For generating a random string you call generate() function.By default it generate 16 character string.

const randomString = require('randomized-string');
randomString.generate(); // xabgtl3yb1Ac0MrQ

or you can use import statment

import randomString from 'randomized-string';

If you want some length to random string pass a number to the function.

randomString.generate(6); // lAo3Bi

To be more specific you can pass an object for more flexibility.This are the listed options you can provide

type options = {
  charset?: 'alphanumeric' | 'number' | 'alphabet' | 'hex' | 'binary' | 'octal';
  lowerCaseOnly?: boolean; //only lowercase letter
  range?: string; // user provided charset
  length: number; //length of the character if not provided generates 16 characters by default
  upperCaseOnly?: boolean; // only uppercase letter
  insertSymbol?: boolean; // insert symbols to given charset
  symbolsOnly: boolean; //only symbols
  prefix: string; // add before string
  suffix: string; // add after the string
};

passing down the options

Generate string only in the given string range

randomeString.generate({
  range: 'abc123',
  length: 6,
});

// a3cb21

You can set also set type of string

randomString.generate({
  charset: 'number',
  length: 10,
}); //2342612198

randomString.generate({
  charset: 'alphabet',
  length: 10,
}); //SoWhopDFTb

randomString.generate({
  charset: 'hex',
  length: 6,
}); // C0faDB

You can insert prefix prefix or suffix characters. Note that the length of the prefix or suffix is not counted with the length of the random string.

randomString.generate({
  length: 10,
  prefix: 'pre-',
}); //pre-GaKdvH8Bro
randomString.generate({
  length: 10,
  suffix: '-suff',
}); //0YcCeMISpE-suff

You can also insert symbols if you pass set the insertSymbol option to true. But it doesn't work for binary or octal or hex charset option.

randomString.generate({
  insertSymbol: true,
});
//bd@MK8ˆIvpGVoorO{FJkf]iMz,{1+-8g

You can pass the option upperCaseOnly to make the string only capital and lowerCaseOnly to make the string lowercase

randomString.generate({
  charset: 'alphabet',
  upperCaseOnly: true,
});
//ODEISDGQXUGGOHHG
randomString.generate({
  lowerCaseOnly: true,
});
//fnzkamf0svos4yso

You can get symbols only if you set option symbolsOnly:true,

randomString.generate({
  symbolsOnly: true,
  length: 10,
});
// ?[]}$'&,{]

For fun you can also generate random emojis using generateUnicodeEmoji(length)

randomString.generateUnicodeEmoji(1); //🍍

Command Line Usage

First the package should be installed globally

$ npm install randomized-string -g

$ yarn add randomized-string

$ randomized-string

 // Urp0YDaIHWn7YCCF

$ randomized-string  upperCaseOnly=true charset=alphanumeric

 // DX5ACJP1FJN5Q79Z

$ randomized-string   charset=alphanumeric insertSymbol=true length=8
// S8Cza8v^

$ randomized-string  prefix=pre-
 //pre-KOyWstwcpA6sLaH3

$ randomized-string  generateUnicodeEmoji length=5
