i have a Login module which contains login.html. i want login to be the default module and login.html as the default opening page.
in main.ts file you will have something like this
import { AppModule } from './app.module';
platformBrowserDynamic().bootstrapModule(AppModule);
replace this with
import { LoginModule } from './login.module';
platformBrowserDynamic().bootstrapModule(LoginModule);
