lib-mod10

A node module for checking numbers against luhn algorithm

Installation

yarn add lib-mod10

Usage

The library exposes two methods:

  • compute() => Compute checksum for input number
  • check() => Checks input number against luhn algorithm

Compute

// Import lib-mod10
import Mod10 from 'lib-mod10'

// Compute checksum for a random number
const cheksum = Mod10.compute('1234567890') // Should output 3

Check

// Import lib-mod10
import Mod10 from 'lib-mod10'

// Check random number against luhn algorithm
const isValid = Mod10.check('12345678903') // Should output true

Demo
