Banking Application

A full-stack banking application built with React (frontend) and Express + MongoDB (backend).

Prerequisites

• Node.js (v12 or higher)
• MongoDB (v4 or higher)
• npm or yarn

Database Setup

Option 1: Use Shared Development Database

Connect to the shared development database with these credentials:

• Username: user_admin
• Password: password
• Database: moniterdb

Option 2: Create Your Own Local Database

1. Install MongoDB on your machine
2. Start MongoDB service:

   mongod

3. Create a new database (it will be created automatically on first connection)

Installation

Backend Setup

1. Navigate to the backend directory:

   cd backend

2. Install dependencies:

   npm install

3. Create a .env file in the backend directory:

   PORT=3001
   MONGODB_URI=mongodb://user_admin:password@localhost:27017/bankdb
   

   For your own local database, use

   PORT=3001
   MONGODB_URI=mongodb://localhost:27017/bankdb
   

4. Start the backend server:

   npm run dev

   The backend will run on http://localhost:3001

Frontend Setup

1. Navigate to the frontend directory:

   cd frontend

2. Install dependencies:

   npm install

3. Create a .env file in the frontend directory:

   REACT_APP_API_URL=http://localhost:3001
   

4. Start the frontend development server:

   npm start

   The frontend will run on http://localhost:3000

API Endpoints

• GET / - Welcome message
• /accounts - Account management routes
• /transactions - Transaction management routes

Development

• Backend runs with nodemon for auto-reload on file changes
• Frontend uses React development server with hot reload

Troubleshooting

MongoDB Connection Issues

• Ensure MongoDB service is running
• Check if the port 27017 is not blocked
• Verify credentials in .env file

Port Already in Use

If port 3001 or 3000 is already in use, change the PORT in the respective .env file.
