Multi UI's & Spring Boot CRUD Backend

Revisited Baeldung Tutorial CRUD Application with intiallty with React and Spring Boot — see https://www.baeldung.com/spring-boot-react-crud

I migrated the initial tutorial to the Vite starter Template Vitamin 2.0, see spring-boot-react-crud-revisited2

The intention of this project is to show 3 different Frontend Stacks (React, Svelte and Spring MVS with Thymeleaf) using the same Spring Boot Server Backend.

Rather than showcasing a single framework, the goal is to examine how architectural decisions change when using:

• server-side MVC (Thymeleaf)
• client-side SPAs (e.g. Svelte, React)

while keeping the domain model, validation rules, persistence layer, and error semantics identical.

By sharing one backend across multiple UI paradigms, the differences become explicit:

• where validation belongs
• how errors are propagated and handled
• how much state lives on the client vs the server
• and how complexity, maintainability, and developer experience evolve.

The intent is not to declare a “best” approach, but to make trade-offs visible and concrete through working code and thus make change and evolution of code possible.

This is work in progress.
