I just found vaadin and find it great. I would like to see a tutorial, how to use vaadin as a frontend for different downstream microservices. An important point would be how to use authentication from vaadin to the microservices, so only a logged in user can make requests to the backend. For pure Spring Boot I use an edge service as gateway, which makes a JWT check and send the data as x-headers to my services, but I don't know how to do this with vaadin yet.

A vaadin/full java tutorial to how make diferent web layouts would be nice. Maybe a simple application with diferent layouts but doing the same job.

Hi Marcus. Nice one, and thanks for sharing.
This is the kind of stuff I want to see more demo on how to liaise on hilla to accomplish them. Is it possible to show how to notify only specific connected user or group? The idea behind being the segregation of backend tasks notifications based on criteria
