Random Code Generator

Description

Random Code Generator is an npm package that provides a simple and flexible way to generate random invite codes consisting of numbers, letters, or a combination of both. This library is particularly useful for applications that require the generation and validation of random codes, such as invitation systems, voucher generation, or security token creation.

Installation

You can install the Random Code Generator package via npm:

npm install alex-random-code-generator

Usage

To use the Random Code Generator in your project, you need to import the CodeGenerator class and the CodeTypes enum from the package as follows:

import { CodeGenerator, CodeTypes } from 'alex-random-code-generator';

Creating a CodeGenerator Instance

You can create a CodeGenerator instance by specifying the desired code type (Numbers, Letters, or NumbersAndLetters) and an optional length (default is 6):

const generator = new CodeGenerator(CodeTypes.NumbersAndLetters, 8);

Generating Random Codes

Use the generate method to generate a random code based on the chosen type and length:

const randomCode = generator.generate();
console.log(randomCode); // Example output: "3a7b9d2c"

Validating Codes

You can also validate a code to ensure it matches the chosen type. Use the validate method to check if a code is valid:

const isValid = generator.validate("3a7b9d2c");
console.log(isValid); // Example output: true

Examples

Generating a Code with Numbers Only

const generator = new CodeGenerator(CodeTypes.Numbers, 6);
const code = generator.generate();
console.log(code); // Example output: "573812"

Generating a Code with Letters Only

const generator = new CodeGenerator(CodeTypes.Letters, 8);
const code = generator.generate();
console.log(code); // Example output: "abcdEFGH"

Generating a Code with Numbers and Letters

const generator = new CodeGenerator(CodeTypes.NumbersAndLetters, 10);
const code = generator.generate();
console.log(code); // Example output: "a1B2c3D4e5"
