Building a REST API is easy. Building a production-ready REST API is not. Using: Spring Boot You can quickly develop APIs, but without proper design, they fail in production due to: ❌ Poor validation ❌ Security gaps ❌ Performance issues 👉 This guide shows how to build enterprise-grade REST APIs step-by-step . đź–Ľ️ REST API Architecture (JPG) 🏗️ 1. API Architecture (Layered Design) Standard Layers: Controller → Handles requests Service → Business logic Repository → Database DTO → Data transfer 👉 This ensures: ✔ Clean code ✔ Scalability ✔ Maintainability ⚙️ 2.
