Travel Booking Microservices

This repository demonstrates a microservices architecture using NestJS. The project consists of several distinct services, each serving a specific purpose. Let's dive into the details:

Services

1. auth-service: Responsible for authentication and user management.
2. user-service: Handles user-related operations.
3. booking-service: Manages booking-related functionality.
4. mailer-service: Sends email notifications.
5. payment-service: Integrates with Stripe for payment processing.

Features

• Authentication Service:

  • User Signup: Customers can create new accounts by providing their personal details.
  • User Signin: Registered customers can sign in to access their accounts.
  • Password Management: Customers can reset and update their passwords securely.
  • User Session Management: Maintains user sessions and ensures secure access to protected resources.

• Booking Service:

  • Ticket Booking: Enables users to book travel tickets.
  • Ticket Cancellation: Allows users to cancel their booked tickets.
  • Ticket Update: Allows users to update their booked tickets.

Other Features

RabbitMQ Communication

I use RabbitMQ as our message broker for communication between services. It ensures reliable and asynchronous communication.

Different Databases

• User Service and Auth Service use PostgreSQL for storing user data.
• Booking Service and Payment Service utilize MongoDB for booking and payment-related data.

CQRS Implementation

I've implemented the Command Query Responsibility Segregation (CQRS) pattern in the Booking Service and Payment Service. This separation of read and write operations enhances scalability and maintainability.

OAuth2 with JWT

• OAuth2 is used for authentication and authorization.
• JSON Web Tokens (JWT) are issued upon successful authentication, allowing secure communication between services.

Stripe Integration

I've integrated Stripe as our payment service provider. It handles payment processing securely.

Redis Caching

For quick data retrieval, we've implemented Redis caching. Cached data improves response times and reduces load on databases.

Dockerization

Each service is containerized using Docker, ensuring consistent deployment across environments.

Husky for Development

I've set up Husky to streamline development workflows. It enforces code quality checks and runs tests before commits.
