Don't miss my new blog post in the Road to GA series to learn how the Spring team empowers Spring developers to make their Spring Boot 4 application null-safe, to reduce or remove the risk of NullPointerException and to solve "the billion dollar mistake"! spring.io/blog/2025/11...

20 years ago, we moved from client/server applications to web applications.
10 years ago, we moved from web applications to single-page applications (SPAs).
What many still don’t realize: SPAs are client/server applications again.
Technology changes - the architecture patterns repeat.

Be careful when using Spring Data: if you don't need the total number of elements, you shouldn't use `Page` as the return type. Spring Data performs two queries: one to count and one to fetch when Page is returned. Instead, you can use Slice.

@martinelli.ch on why Vaadin works well with AI code generation: server-side Java keeps logic secure, strong typing catches AI mistakes at compile time, and single-language stack = no context switching. Worth a read 👇

Ever wondered why in a Spring MVC Controller the query parameters are mapped using a @RequestParam annotation and not a @QueryParam annotation? If you look at the JavaDoc you'll find the answer:
In Spring MVC, "request parameters" map to query parameters, form data, and parts in multipart requests.

The reason for creating tests is not to achieve 80% code coverage, but to gain the assurance that the application will still work after a change.
