Adonisjs Card Validator ▲

Introduction

Adds credit/debit card validation functionality to Adonisjs using Luhn algorithm

Step One - Install

Via Adonis CLI

adonis install @shagital/adonisjs-card-validator

Via npm/yarn

• Install package

// via npm
npm require @shagital/adonisjs-card-validator

// via yarn
yarn add @shagital/adonisjs-card-validator

Step Two - Register Provider

Open start/app.js and add @shagital/adonisjs-card-validator/providers/CreditCardValidationProvider to the providers array

Usage

You use the card, cvv and cardExp validation syntax just like you'd normally do validation in Adonisjs. Examples below: NOTE: The specified card type need to be supported. Currency supported card types are:

• visaelectron
• maestro
• forbrugsforeningen
• dankort
• visa
• mastercard
• amex
• dinersclub
• discover
• unionpay
• jcb

controller method

//app/Controllers/Http/UserController

const { validate } = use('Validator')

class UserController {

  async store ({ request, session, response }) {
    const rules = {
      card: 'required|card', // validate card number
      cvv: 'required|cvv', // validate cvv2
      expiry_date: 'required|cardExp', // validate card expiry date in the format YYYY-MM
    }

    const validation = await validate(request.all(), rules)

    if (validation.fails()) {
      session
        .withErrors(validation.messages())
     
      return response.redirect('back')
    }

    return 'Validation passed'
  }
}

Validator

//app/Validators/StoreUser.js

'use strict'

class StoreUser {
  get rules () {
    return {
       card: 'required|card:mastercard', // validate mastercard card number
       cvv: 'required|cvv:mastercard', // validate mastercard cvv2
       expiry_date: 'required|cardExp', // validate card expiry date in the format YYYY-MM
    }
  }
}
