Code splitting

[aliwa]

Hi all,

A simple question: how to make code splitting with gwt-presenter?
Have you an example?

thank you in advance :)

I have to add that i use GIN for dependency injection.

Is there any idea plz!

This project is sort of dead ...
Check out GWTP (gwt-platform), where code-splitting is a nobrainer :)

Hi,

I have worked with gwt-presenter+gwtdispatch+GIN and it is impossible to use gwtp now. do you think code splittings is feasible with these libraries?

Hi,

What have you tried so far?

Hello,

Code splitting is fairly straight forward with gwt-presenter - the key
is to use a GIN provider to sever the hard references to your
presenters:

import com.google.inject.Provider;

public class PresenterRegistry {

private Provider<MyPresenter> myPresenterProvider;

@Inject
public void setMyPresenter(final Provider<MyPresenter> provider)
{
myPresenterProvider = provider;
}

public void revealMyPresenter()
{
GWT.runAsync(new RunAsyncCallback()
{
@Override
public void onSuccess()
{
final MyPresenter<?> presenter = myPresenterProvider.get();
presenter.revealDisplay();
}
});
}
}

I hope that helps.

Chris.

I agree with Espen. You should consider GWT-platform for your project. It is a fork of gwt-presenter but since then it has differentiated a lot and many features have become available to ease GWT (MVP) development. It also has an active community of users and contributors.  

Nevertheless, since you are using GIN, code splitting can be easily achieved with an AsyncProvider. I haven't tried it with gwt-presenter but I believe it can work. Say, you want to code split MyPresenter. Instead of injecting the presenter itself you should inject an AsyncProvider<MyPresenter> and GIN will do the rest. The javascript for the presenter will be fetched the first time that you'll ask your AsyncProvider for this presenter (i.e. myAsyncProvider.get()). 

Hope it helps,

Yannis

@Chris Try to use an AsyncProvider instead of a Provider in case that you want to get rid of the GWT.runAsync stuff. GIN will take care of it.  

Cheers,

Ah, yes - good call. I came up with my solution prior to GIN's
implementation of AsyncProvider. I get the same end result though and
it's worked well for us for a while now.
