Hahaha... I guess Vaadin's marketing team is at it again.<p>This is just re-branded Vaadin all over again trying to sell a product nobody wants and it is not even their own.<p>This is just Spring Boot + Custom typescript cobbled together and called a framework. It is hardly modern by any standards and frankly a bad idea to build web-apps that locks the users this way.<p>Please take your marketing bs somewhere else.
If you put @AllArgsConstructor from Lombok on that PersonEndpoint class, you should be able to remove the boilerplate `public PersonEndpoint(PersonRepository repository) { this.repository = repository; }` constructor entirely since the Lombok annotation will generate it for you. Seems reasonable to do if the point is to show "modern Java".
I don't consider Spring Boot to be modern Java. At least not if it uses JPA/Hibernate which is solving the 1990s problems of enterprise Java apps.
