Angular 4.0.0 could not find bootstrap code

Question

Error : Tried to find bootstrap code, but Specify either statically analyzable bootstrap code or pass in an entryModule to the plugins options.

main.ts

getHttp().get('/assets/config.json').toPromise()
 .then((res: Response) => {
 let conf = res.json();
 platformBrowserDynamic().bootstrapModule(createAppModule(conf));
})

I am using angular-cli. With angular v2.3.1 this code was working fine.

I want to fetch json and pass it to @Ngmodules providers

{ provide: Config, useValue: conf } 

Answer 1

If the data you are fetching from config.json are just about a configuration of an application module and you are trying to create a Config service to store them, I think the best would be to assign it to the environment and read it in your Config service later. The environment is available in main.ts, so no hacking (createAppModule) needed.

import { environment } from './environments/environment';
import { AppModule } from './app/';

getHttp().get('/assets/config.json').toPromise()
   .then((res: Response) => {
       let conf = res.json();
       environment.settings = conf;
       platformBrowserDynamic().bootstrapModule(AppModule);
});

You must also declare all new properties of environment in your src/environments/environment.ts file.
