This is something I have been pushing my teams to do. We keep out GWT apps very simple, just "CRUD" so that they can run in DevMode but also de-couple from business logic and background tasks as much as possible, a microservices approach.
If that is not enough we equip the GWT app strictly with front-end code, we keep the back-end services in a separate application and bridge the two with a remote API (e.g. REST+JSON). I believe this is what is implied by "pure GWT frontend" On Tuesday, 13 April 2021 at 20:14:16 UTC+1 t.br...@gmail.com wrote: > What do you mean by "pure GWT frontend" ? Do you need servlets ?
