Angular2 AoT Compiler Errors

When I try to compile my project with ngc, it throws the below error:

Error: Error encountered resolving symbol values statically. Function calls are not supported. Consider replacing the function or lambda with a reference to an exported function (position 92:25 in the original .ts file), resolving symbol AppModule in

In my App Module I have the below providers and probably this is causing the project. I am not sure what exactly is wrong with this?

providers: [
        GlobalService,
        {
            provide: Http,
            useFactory: (backend: XHRBackend, defaultOptions: RequestOptions, globalService: GlobalService) => new HttpLoading(backend, defaultOptions, globalService),
            deps: [XHRBackend, RequestOptions, GlobalService]
        }
    ],

pls try

export function httpFactory(backend: XHRBackend, defaultOptions: RequestOptions, globalService: GlobalService) {
  return  new HttpLoading(backend, defaultOptions, globalService);
}

providers: [
        GlobalService,
        {
            provide: Http,
            useFactory:  httpFactory,
            deps: [XHRBackend, RequestOptions, GlobalService]
        }
    ],

Oh for crying out loud. So to get decent load times for Angular2 apps we need to use ngc. To use NGC, we now need every every vendor of angular2 libs to now include a .metadata.json file? So now we’re dependent on that as well?

So what are we going to do since Angular2 allows people to write components in pure JS, and since JS is not Typescript, these libraries/modules will never have a .metadat.json and thus can never be used by AOT?

I’ve tried three different ways to shrink down a angular2 app to a decent size and reduce download times by bundling stuff up into one module, and all three have been dead ends. Various, errors, poor documentation, and our app takes 10 seconds to start due to the hundreds of npm deps it loads at boot.

• Angular-cli? Buggy. No go
• Angular aot compiler? Not every already shipping angular2 lib has .metadata.json files
• Rollup? Issues with libs being shipped in various incompatible module formats in npm. Some are commonjs, some amd, etc, and rollup can handle some but not others.

Is there a sane "WORKS NOW’ way to make a single js bundled app file? Even with no AOT? For a 1.0 release this is maddening.

If I were to jump through these hopes, would I finally a single file, or nearly single Angular2 app? Or do I need to find a bundler that would then work with everything else we use?
