GWT Best Practices - MVP

Question

A question for all the GWT gurus out there.

I'm a newbie in GWT and am trying to understand the best practices of coding a GWT application. I have gone through "Large scale application development and MVP" based on Ray Ryan's talk at Google I/O 2009 and it has given me a good starting point. I downloaded the sample source code as well for the Contacts application based on the best practices listed.

The application I'm trying to develop using GWT is a bit bigger (in terms of the modules involved) when compared to the sample "Contacts" application & so I want to split it up into multiple functions.

I have been reading that having a single Entry point in a GWT application is a good idea, and I don't want to dump all the code in one single AppController class & one single RpcService, what would be the best approach in this situation?

How would I go about dispatching the control to multiple controllers? Is there a way to achieve this using some classes in the GWT framework?

Answer 1

If you are developing very big application then split your application into multiple modules. For client side MVC pattern I suggest PureMVC.

Answer 2

If you're worried about initial load size and it's possible to load your big app in different chunks, consider Code Splitting

Answer 3

For large GWT apps, a framework like gwt-platform (which is a fork of gwt-presenter and gwt-dispatch) is almost necessary. It provides things like Places for handling location/history, a handy Presenter framework, EventBus, and really simple codesplitting.
