FIRST REST API with Spring Boot 3 (Live Coding from Scratch)

Описание: 🚀 In this live session, we build our very first REST API using Spring Boot 3 from scratch.

If you want to learn backend development with Java and understand how REST APIs work in real projects, this is the perfect place to start.

In this live coding session you will learn:

• How to create a Spring Boot 3 project
• How REST APIs work
• How to create an Entity with JPA
• How to use JpaRepository
• How to create Service and Controller layers
• How to test your API with Postman
• How Spring Boot handles HTTP requests internally

This is the beginning of our backend development journey.

Stay until the end because in the next live we’ll add validation, DTOs, and proper error handling like a real production API.

🔥 Let’s build it step by step.
