🚀 Spring Boot Bookstore REST API is one of the most structured backend projects I’ve worked on — a robust and production-ready RESTful web service built using Spring Boot, Hibernate, and PostgreSQL. It supports full CRUD and partial update operations for managing books and authors.

📚 What I Built

The application was designed with clean architecture principles in mind. Key features include:

  • ✅ CRUD + PATCH for books and authors
  • 🔄 Pagination for listing books
  • 🔧 DTO ↔ Entity mapping for data abstraction
  • 🧪 100% test coverage using JUnit 5 and AssertJ
  • 🐳 Dockerized deployment to AWS LightSail

The goal was to build a backend API that follows best practices like separation of concerns, test-driven development, and RESTful principles — all of which I learned and implemented step-by-step.

🎓 What I Learned from DevTiro

I followed the DevTiro Spring Boot YouTube series — and it was a game-changer for understanding real-world backend development. Some core takeaways:

  • How to structure a layered architecture (Controller → Service → Repository)
  • How to write clean, testable code with DTOs and mappers
  • Writing integration tests using JUnit + Spring Boot Test with test containers
  • Configuring and using Spring Data JPA effectively
  • Clean Git-based project management and Docker integration

This project taught me more than any tutorial ever could — because I didn’t just follow along, I extended and deployed it!

☁️ Deployment

The API is containerized using Docker and deployed to AWS LightSail, making it production-ready. I also used environment-specific profiles and configuration best practices to ensure scalability.

Thanks for reading! If you’re learning Java backend development, I highly recommend DevTiro’s content — and building something end-to-end like this to truly master Spring Boot. 💡
