Re: Exposing GWT components based on Elemental2 to TypeScript ?

I'm currently investigating how to expose a GWT based component (that uses JsInterop and Elemental2) to JavaScript and TypeScript.

The goal is that this component should be reusable in an Angular 4 application, but also in GWT applications.

I think you'll be delighted by J2Cl when available, and then use Clutz and/or Gents (https://github.com/angular/clutz) for TypeScript interop (see also https://github.com/material-components/material-components-web/issues/134 )

I'm finding it really hard to create a .d.ts file that is acceptable to Angular 4 (documentation and reality seem to clash).

I was wondering, am I the first to try this ? 

For now I gave up on the attempt to declare a proper .d.ts file and just declared the reference as any.

But somehow I think it would be nice if GWT had a linker that could actually output that TypeScript file automatically saving me from doing double work.

You could possibly use an annotation processor to do that (processing all jsinterop.annotations.* annotations)

 

I am using the sso-linker in GWT to get all my JsType classes exported and I just load the generated nocache.js file.

Is there a way to make sure that the contents of that file does not cache with other JS objects ? 

Can I somehow declare at compile time what I want to have exported ?

Yes, through -includeJsInteropExports and -excludeJsInteropExports patterns (added in 2.8.1)

There seems to be more in the output than what I actually need (I don't need an EntryPoint for example).

The entry point is required in GWT, but can be empty / no-op if you export JsInterop types.
