A simple card validator based on the Braintree validator

Getting Started

1. Install the card-validator 💳

yarn add @malga/card-validator
# or
npm install @malga/card-validator
# or
pnpm add @malga/card-validator

2. Now just validate your cards

import { valid } from '@malga/card-validator'

valid.number('6274160007029307')
/*
{
  card: {
    niceType: 'VR',
    type: 'vr',
    patterns: [ 627416, 637036 ],
    gaps: [],
    lengths: [ 16 ],
    code: { name: 'CVV', size: 3 },
    matchStrength: 6
  },
  isPotentiallyValid: true,
  isValid: true
}
*/

3. Mask a card number

import { maskCardNumber } from '@malga/card-validator'

maskCardNumber('0000000000000000')
// 0000 0000 0000 0000
