We don't really know how GWT 3 will look like, but we know we'll base it upon j2cl, which means no JSNI and GWT.create() magic (no generators, no deferred-binding configuration in XML files). We've said repeatedly that we were waiting to actually being able to start *playing* with j2cl to have a better understanding of what would be possible or impossible, what would need to be done, etc. We want to start prototyping things. And only then we'll be able to form a better image of what GWT 3 could look like. Incidentally, you've had 2 years to start planning for it: - remove as much JSNI as possible, leaving mostly one-liners that could then easily be replaced with JsInterop (and now that JsInterop is here with a beta of Elemental 2, that last migration can be started too) - replace <replace-with> in gwt.xml with System.getProperty("…") and a switch…case (or if/else for more complex cases); this is relatively straightforward and can possibly even be (partially) automated (first step: generate, from the XML, a proxy class whose constructor does the switch on implementation, and replace the <replace-with> rules with a single one using the proxy class; second step: generate a static factory with that same switch code, and use it instead of the GWT.create()) - replace generators with annotation processors (first step: have the processor generate a *.gwt.xml file with <replace-with> rules; second step: rpelace the GWT.create() calls) or preprocessors (or a combination of both). GWT-RPC *is* problematic, but not insurmountable. People (me included) question whether this is a good idea though, but others disagree. We haven't seen the community engaging much in any discussion trying to move things forward though: if I tell you GWT-RPC won't be the same, can you tell me how you'd like it to be? (a preprocessor? a whitelist of classes in annotations on the RemoteService interfaces? what if it generated server-side code too instead of the serialization policy files?) Fortunately, there have been people trying new things though (autorest for example). UiBinder and ClientBundle have their issues, too; but maybe they need to be replaced with new tools leveraging the new toolchain, along with automated migration tools? Regarding ClientBundle, isn't it now seen as a bad practice (with HTTP/2) to bundle assets inside the JS code? -- You received this message because you are subscribed to the Google Groups "GWT Contributors" group.
