Luhnsoft

This library implements Luhn Algorithm to validate credit cards, IMEI etc. It does support string (english, arabic or persian digits) or number as an input. It's also typed with typescript with zero dependency.

Usage

First install the package with npm or yarn or pnpm.

npm install luhnsoft

or

yarn add luhnsoft

or

pnpm add luhnsoft

Then import validate from luhnsoft and put in the credit card or IMEI digits as an input.

import validate from 'luhnsoft';

const isValid: boolean = validate(3570861********);

API

• You can use string or number type digits.
• The validate function already converts arabic and persian digits to english and makes sure all extra characters are removed so you don't need to worry about removing characters like - or empty spaces from input beforehand.

Testing

The tests are written with vitest that can be used to verify the package before usage.
