Backend

The backend of the Ethereum Tracker is built with Node.js and Express. It handles API requests, connects to MongoDB, and manages rate limiting and request counting.

Technologies Used

• Node.js: JavaScript runtime built on Chrome's V8 engine.
• Express: Web application framework for Node.js.
• MongoDB: NoSQL database for storing transaction and price data.
• Mongoose: ODM library for MongoDB and Node.js.
• dotenv: Loads environment variables from a .env file.
• cors: Middleware for enabling CORS.
• express-rate-limit: Middleware for rate limiting.

Setup

1. Clone the repository:

   git clone <repository-url>

2. Navigate to the backend directory:

   cd backend

3. Install dependencies:

   npm install

4. Create a .env file and add your MongoDB URI:

   MONGO_URI=<your-mongodb-uri>
   PORT=3000

5. Start the backend server:

   npm start

API Endpoints

• GET /api/transactions/:address: Fetch transactions for a given Ethereum address.
• GET /api/eth-price: Fetch and store the current Ethereum price.
• GET /api/user-expenses/:address: Get user expenses based on transactions.

Testing

You can test the backend using tools like Postman or cURL.
