🚀 Setup Instructions

1. Clone the repository:

git clone https://github.com/michelleog2351/Secure-Bank-Application.git

2. Navigate to the project directory:

cd secure-banking-system

3. Install the required dependencies e.g. npm install mysql2:

npm install mysql2

4. Ensure MySQL is running and create a bank_system database using the provided .sql file.

net start mysql

5. Start the server:

node server.js

6. The server runs on:

Bank System Server listening on port 3000...
Successfully connected to MySQL database bank_system

🔐 Security Features

• User Authentication

• Password hashing using bcryptjs

• Input validation and sanitisation

• Proper error handling and logging

🔄 User Registration & Database Insertion

When a user registers, the system captures their details securely and inserts them into the MySQL database. Example in json:

{
  "first_name": "Shells",
  "last_name": "Stewarts",
  "email": "shelly@atu.ie",
  "phone_no": "+353 657 7652",
  "username": "shell.stews",
  "password": "Happys*1187",
  "balance": 0
}

🧪 Testing

• Manual testing of login and registration flows
• Unit Testing
