Kotlin and Spring Boot: Building Secure REST APIs with JWT

Building secure and efficient backend systems is a core skill for modern web developers. Kotlin and Spring Boot provide a powerful, type-safe, and highly productive combination for creating robust REST APIs. This text-based course guides you through the process of setting up a Kotlin backend, implementing clean RESTful endpoints, and securing your application using JSON Web Tokens (JWT). You will transition from understanding fundamental backend concepts to deploying a secure authentication system. What you'll learn: 1. Understand the core syntax of Kotlin and how it integrates with Spring Boot. 2. Build robust REST APIs with clean, modern routing and request handling. 3. Configure Spring Security to handle user authentication and authorization. 4. Implement secure JWT login flows, including token generation and validation. 5. Apply modern Kotlin features like data classes and null-safety to backend development. 6. Practice writing clean, testable backend code with structured written exercises. You will start with the absolute basics of Kotlin and Spring Boot architecture, establishing a solid foundation of key terminology. From there, you will progress through step-by-step written explanations and code snippets to build a fully functional, secure login system. This course is designed for beginning developers, students, and backend enthusiasts who want to learn Kotlin and Spring Boot. No prior experience with Spring or JWT is required.
