Payment Form App

This is the test task for junior WEB-dev.

Introduction

The goal of this application - is to simulate payment with credit card.

Task conditions and restrictions:

• use Angular (>1.3) for Front-end
• use Nodejs for Back-end with one of the frameworks (express/totaljs/sailsjs/hapi/koajs)
• can't use external Angular modules
• can't use external librarys like jQuery and etc.
• create many validation interfaces

I've added a Mongoose to improve presentation of the data that used in payment transfers and etc.

Because of all this dependences, I chose MEAN template for this app.

Description

Angular

Used to control all user's actions, form validations, for manipulating user's data and etc.

Node

Used to create WEB server with JavaScript

Express

Provides a layer of fundamental web application features

Mongoose

The user's data, that used in application, is contained in 3 models:

• User - represents a bank account (account currency - euro). Example:

{
    "bank_account_value": 999943573,
    "type": "visa",
    "nameOnCard": "MARK ZUCKERBERG",
    "cardNumber": 4444444444444444,
    "expiryDate": "0444",
    "securityCode": 444
}

• Payment Transfers - represents a history of payment transfers. Example:

{
    "bank_account_value_before": 999948017,
    "bank_account_value_after": 999943573,
    "cardNumber": 4444444444444444,
    "nameOnCard": "MARK ZUCKERBERG",
    "amount": 4444,
    "currency": "euro",
    "createdAt": 1473629151733
}

• Card - represents a data of different kinds of credit cards. Example:

{
    "type": "mastercard",
    "first_number": 5,
    "card_number_length": 16,
    "security_code_lenght": 3,
    "logo": "https://s26.postimg.org/iw2z5i4tx/mastercard.png",
    "hint": "../images/card_tooltips/nonamex.png",
    "regex": "^5[1-5][0-9]{14}$"
}

Of course, this data applicable only for presentation, but it helps to understand how app is working.

P.S.

Also for security improvement I used HTTPS protocol, with own created sertificate that can be found in dir /ssl catalogue.

Available card types can be found at https://localhost/api/cards.

All Angular code placed into modules.

Installation

git clone https://github.com/eugrdn/payment-form-app.git
cd payment-form-app
npm install
npm start
# in browser
https://localhost:3000

Attention

Don't forget to change userURI

{
    "mongoose": {
        "options": {
            "config": {
                "autoIndex": false
            },
            "server": {
                "socketOptions": {
                    "keepAlive": 1
                }
            }
        },
        "userURI": "YOUR MONGOLAB USER CONNECTION"
    }
}

Using

I've created two bank accounts to demonstrate different results of payment processes:

• The first user

	bank account value: 999943573 € (or less)
	name: Mark Zuckerberg
	card type: visa
	card number: 4444 4444 4444 4444
	expiry date: 04/44
	security code: 444

• The second user

	bank account value: 83 € (or less)
	name: Pavel Tech
	card type: amex
	card number: 3733 3333 3333 3333
	expiry date: 03/33
	security code: 333
