A JavaScript module of the luhn algorithm
npm install luhn
The luhn module has unit tests built around it than can be used to verify the package before usage. The tests are written with the Mocha and Should modules and running the below command will import such.
npm test luhn
Once the package has been installed using npm, using the module is very simple. At the moment, the module includes an luhn object that exposes a single method, validate. validate accepts a single string parameter that represents the credit card number.
import luhn from "luhn";
var is_valid = luhn("4111111111111111"); // should respond true.Copyright (c) 2023 James Eggers
