Parse, format, and validate credit card data.
npm install --save creditcards
creditcards exports:
card
cvc
expiration
-
withTypes
(constructs a new copy of the module with custom types)
You can also require modules individually. This is particularly useful if you wish to pass in custom types. card
and cvc
each export a function that accepts an array of card types (see creditcards-types
). expiration
returns an object.
const Card = require('creditcards/card')
const card = Card([visa])
card.isValid('4242424242424242')
// => true
const expiration = require('creditcards/expiration')
expiration.isPast(10, 2010)
// => true
Returns a new copy of the main module with custom types.
