Command

build

Is this a regression?

• Yes, this behavior used to work in the previous version

Description

I am using transloco for localization.
When building (used to be prerendering) now the build process tries to render the pages.
In doing so, it hits this loader, which loads a static asset (the language in question)

@Injectable({providedIn: 'root'})
export class HttpLoader implements TranslocoLoader {
  private http = inject(HttpClient);

  getTranslation(langPath: string): Observable<Translation> {
    return this.http.get<Translation>(`assets/i18n/${langPath}.json`);
  }
}

However, the HTTP request fails, since there seems to not be an http server involved in the SSG process.

If I run this in SSR, it also fails, but that is because it can't handle the path, and requires a full URL (http://localhost:4000/assets/...)

If I accept not having a server, I need to have a similar behavior to what I do during testing:

    if (isPlatformServer(this.platformId)) {
      const path = require('path');
      const filePath = path.join(__dirname, '..', '..', '..', assetPath);
      console.error('filePath', filePath);
      const fs = require('fs');

      const data = fs.readFileSync(filePath, 'utf8');
      return of(JSON.parse(data));
    }

But this relies on node modules, and the builder errors:

The package "fs" wasn't found on the file system but is built into node. Are you trying to bundle for node? You can use "platform: 'node'" to do that, which will remove this error.

Therefore, my issues are:

1. SSG should have some sort of way to load static assets.
2. SSR should not need the full URL. somehow, it should understand that any path requested is under the same host as the REQUEST.

Minimal Reproduction

1. Make a new app, with ssr and ssg ("prerender": true, "ssr": {"entry": "src/server.ts"}`)
2. under src/assets add something.json
3. in the AppComponent's ngOnInit function, make this.httpClient.get('/assets/something.json').subscribe()
4. run ng build --configuration=production

Exception or Error

- SSG should have a way to load static assets
- SSR should be able to load assets using HTTP

Anything else relevant?

In the old prerendering, it used to work.
