Documentation

Modular

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'
}
