Alpha testing of Vaadin 24.6.0.alpha3 vs new Flow features

[mshabarov]

Test the happy path of these new features:

• [ ] WebPush notification options
• [ ] setDragImage
• [ ] exclude Vaadin components
• [ ] easier config for SpringServlet
• [ ] Add support for customizable projectFileExtensions

For anyone willing to start this - I'd love to try and test: -exclude Vaadin components -easier config for SpringServlet

• [x] Web push - ok
• [x] Drag image - ok
• [ ] exclude Vaadin components - works, but no documentation
• [x] easier config for SpringServlet - ok, no doc? Skipping file extensions as I did that feature.

• [x] setDragImage - ok
• [x] easier config for SpringServlet - ok
• [x] frontendExtraFileExtensions - ok, but seems to miss docs. Also see question below

Add support for customizable projectFileExtensions: tested and works when importing things like @CssImport("some.scss"). The new frontendExtraFileExtensions seems not to be documented in https://vaadin.com/docs/latest/flow/production/production-build. A question: I tried set frontendExtraFileExtensions=boh and to import a file into a JS script included with @JsModule ont the view. The JavaScript contains import something from 'Frontend/my.boh?raw';. However, my.boh is not included in the stats JSON. Is this expected?

Side note, the maven plugin documentation seems a bit outdated. For example, it lists an includes setting that does not seem to exist.

I would expect it to be there if it is handled by vite.

As boh marked with ?raw vite imports is as a String and it is thus not handled as a file, mening that vite didn't handle it and it will not show up.

Got it. Thanks for clarification.
