Emit and bundle the definitions?

[JasonKleban]

I'm using webpack 3, ts-loader, and transpileOnly: true along with this fork-ts-checker-webpack-plugin.

My ts-config.json has "declaration": true, but I don't think I'm getting the type definitions because of transpileOnly: true which makes sense to me, since I didn't allow ts-loader to perform the computation of the types.

If that's the true cause, is there a way to output the definitions computed during this ts-checker phase? And is there a way to further bundle those definitions as webpack already does for the output .js file?

Thanks!

Personally I've never used webpack in combination with "declaration": true and so I may not be fully understanding your setup. but Would it work if you had a separate process that generated the type definitions. So, another npm script that you used to just run tsc against to generate *.d.ts files? Just a thought... (not necessarily a useful one)

I've just checked typescript.d.ts and there is a method:

emit(targetSourceFile?: SourceFile, writeFile?: WriteFileCallback, cancellationToken?: CancellationToken, emitOnlyDtsFiles?: boolean, customTransformers?: CustomTransformers): EmitResult;

on Program class.
The fourth argument called emitOnlyDtsFiles might be something you are interested in. I don't have a time to implement this in near future so PR's are welcome :)
