Ts-randomstring NPM

ts-randomstring

A simple Node-based library written in TypeScript that allows you to generate random strings (a)synchronously.

Installation

NPM

npm install ts-randomstring

Yarn

yarn add ts-randomstring

Usage

Consumers are able to use both synchronous and asynchrounous (via callback) functions and class methods.

Exported function examples:

import { generateRandomString } from "ts-randomstring/lib"

// Synchronously generate a random string via function.
const randomString = generateRandomString();

import { generateRandomStringAsync } from "ts-randomstring/lib"

// Asynchronously generate a random string via function and callback.
generateRandomStringAsync((error, randomString) => {
    if (error === undefined) {
        // Use your randomly generated string.
        console.log(randomString);
    } else {
        // Handle error.
        console.log(error);
    }
});

Exported class method examples:

import { RandomString } from "ts-randomstring/lib"

// Synchronously generate a random string via class method.
const randomString = new RandomString();
const rand = randomString.generate();

import { RandomString } from "ts-randomstring/lib"

// Asynchronously generate a random string via class method callback.
const randomString = new RandomString();
randomString.generateAsync((error, rand) => {
    if (error === undefined) {
        // Use your randomly generated string.
        console.log(rand);
    } else {
        // Handle error.
        console.log(error);
    }
});

Examples of random string options (demonstrated via functions):

import { generateRandomString } from "ts-randomstring/lib"

// Setting length.
const randomString = generateRandomString({
    length: 128
});

import { generateRandomString, CharacterSetType } from "ts-randomstring/lib"

// Setting length and character set.
const randomString = generateRandomString({
    length: 64,
    charSetType: CharacterSetType.Hex
});

import { generateRandomString, CharacterSetType, Capitalisation } from "ts-randomstring/lib"

// Setting length, character set, and capitalisation style.
const randomString = generateRandomString({
    length: 32,
    charSetType: CharacterSetType.Alphanumeric,
    capitalisation: Capitalisation.Uppercase
});
