OK, now I understand you 😉 Yes, we always have to separate the Client and the Server part. This is also GWT best practice.
But if you are using JavaScript on browser you lose the advantages like: 1. We use *Java* as the language 2. We have the best *ecosystem* like libraries, frameworks, build system and IDEs. 3. We know best design patterns to make our apps maintainable like Dependency Injection, Mock Testing and many other just take a look at: http://bit.ly/DesignPatternsJava 4. … and if you use Java on the server-side with *Spring Framework* or *JavaEE* you have *one language* through the whole stack. So, you could reuse Validation APIs, Business Rules, Business Model, etc. from server to client. I've built this sample project: https://github.com/gwtboot/domino-rest-enum-date to show some reuse for Client and Server and I plan to write more articles on this topic: Dependency Injection, Mocking Test, Validation API, Business Rules - all from Server to Client. This type of reuse cannot be done if you are using JavaScript / TypeScript on the web browser... Thanks, Lofi rmr...@gmail.com schrieb am Montag, 28.
