Simple Card is a plug and play module, import, require, or even script tag it in

Standard JS

import { validate } from 'simple-card'; validate(data);

CommonJS

const { validate } = require('simple-card'); validate(data);

Browser

<script src="/path/to/simple-card.min.js"></script> <script> simpleCard.validate(data); </script>

You can find most of the documentation for simple card here: https://www.dusty.codes/simple-card

Simple Card is completely modular which means each piece of functionality can be imported by itself directly, or with destructuring.

Example:

import validate from 'simple-card/validate' import num from 'simple-card/number' import cvn from 'simple-card/cvn' import expired from 'simple-card/expired' import matches from 'simple-card/matches' // Or with destructuring import { validate, number, cvn, matches, expired } from 'simple-card'

You can then call each function individually.

This also works with commonjs you just need to point directly to the file you want

NOTE: In order to use validate you need to pass a full card object to it like so:

{ number: '4111 1111 1111 1111', cvn: '342', date: '12/20' }
