Uber Microservices with Captain, Ride, and User Servers

This project is a microservices-based Uber clone with separate services for user management, ride handling, and captain operations. The services communicate using RabbitMQ for asynchronous messaging.

Features

• User Service: Registration, login, logout, profile management, and ride acceptance.
• Captain Service: Registration, login, logout, profile management, availability toggle, and ride handling.
• Ride Service: Ride creation and acceptance.
• Authentication: JWT-based authentication for secure API endpoints.
• Asynchronous Communication: Uses RabbitMQ (amqplib) for message passing between services.

Tech Stack

• Backend Framework: Express.js
• Database: MongoDB (via Mongoose)
• Authentication: JWT & Bcrypt
• Message Queue: RabbitMQ (amqplib)
• HTTP Requests: Axios (only in Ride Service)
• Environment Management: Dotenv

Microservices Overview

1. Captain Service (/captain)

Handles captain-related actions such as registration, authentication, and ride availability.

Endpoints:

• POST /register - Register a new captain
• POST /login - Login captain
• GET /logout - Logout captain
• GET /profile - View captain profile (Authenticated)
• PATCH /toggle-availability - Toggle captain availability (Authenticated)
• GET /new-ride - Listen for new ride requests (Authenticated)

Dependencies:

"amqplib": "^0.10.5",
"bcrypt": "^5.1.1",
"cookie-parser": "^1.4.7",
"dotenv": "^16.4.7",
"express": "^4.21.2",
"jsonwebtoken": "^9.0.2",
"mongoose": "^8.10.0",
"morgan": "^1.10.0"

2. User Service (/user)

Manages user authentication, profiles, and accepted rides.

Endpoints:

• POST /register - Register a new user
• POST /login - Login user
• GET /logout - Logout user
• GET /profile - View user profile (Authenticated)
• GET /accepted-ride - Fetch accepted rides (Authenticated)

Dependencies:

"amqplib": "^0.10.5",
"bcrypt": "^5.1.1",
"cookie-parser": "^1.4.7",
"dotenv": "^16.4.7",
"express": "^4.21.2",
"jsonwebtoken": "^9.0.2",
"mongoose": "^8.10.1"

3. Ride Service (/ride)

Handles ride creation and acceptance.

Endpoints:

• POST /create-ride - Create a new ride (User Authenticated)
• POST /accept-ride - Accept a ride (Captain Authenticated)

Dependencies:

"amqplib": "^0.10.5",
"axios": "^1.7.9",
"bcrypt": "^5.1.1",
"cookie-parser": "^1.4.7",
"dotenv": "^16.4.7",

Installation & Setup

Prerequisites:

• Node.js (>=14.x)
• MongoDB (running locally or via cloud)
• RabbitMQ (for message queueing)

Steps to Run Locally

1. Clone the repository:

   git clone https://github.com/your-username/uber-microservices.git
   cd uber-microservices

2. Install dependencies for each service:

   cd captain && npm install
   cd ../user && npm install
   cd ../ride && npm install

3. Create .env files for each service:
   • Example:

     PORT=5000
     MONGO_URI=mongodb://localhost:27017/uber_service
     JWT_SECRET=your_jwt_secret
     RABBITMQ_URL=amqp://localhost

4. Start MongoDB and RabbitMQ.
5. Run each service:

   cd captain && npm start
   cd ../user && npm start
   cd ../ride && npm start

API Authentication

• Uses JWT (JSON Web Tokens) for secure API access.
• Include Authorization: Bearer <token> in headers for protected routes.

---

Future Improvements

• Implement WebSockets for real-time ride updates
• Add payment integration (Stripe, PayPal, etc.)
• Enhance logging and monitoring
