Re: How to do code splitting in latest GWT SDK?

Thank Colin very much. I am following the above url to do code splitting. I found initial download size is very big. Left over code only takes 1%. 75 org.gwtproject.i18n.shared.cldr.impl.CurrencyList_XX are generated. Each has 10741 bytes in size. I don't need all CurrencyList files. How do I reduce  CurrencyList files?

Thanks,

David

While gwt-core and the other refactored modules are intended to be both gwt-compatible and j2cl-compatible, there are a small handful of classes and methods in those refactored modules that, in their original form, were somehow specific to the GWT compiler itself.

The com.google.gwt.core.client.GWT class is one such class that mostly consists of "magic", where there is no java or js implementation of many of its members, but those members exist to allow the compiler to rewrite certain calls with specific behavior. As such, org.gwtproject.core.client.GWT cannot correctly implement all of those methods, and throws exceptions where it must fail.

In a case like this, you must call the original method on the com.google.gwt class while you still use GWT. If you migrate to j2cl and closure, you must find another solution there - j2cl has no split points, and closure-compiler doesn't even think of split points in the same way that GWT does. So, as long as you continue to use GWT 2, call the runAsync() method on the com.google.gwt.core.client.GWT class, and refer to https://www.gwtproject.org/doc/latest/DevGuideCodeSplitting.html for more guidance.

In gwt-core-1.0.0-RC1.jar, I see "Pick either GWT2 split point or Closure-Compiler chunks". Where can I find a code splitting SDK?
