Express launching Angular application I have an express server setup online which loads multiple ports and those ports are setup on subdomains for example. port 9000 loads the main domain.com port 8000 loads the main application at "app.domain.com" port 1000 loads "signup.domain.com" and the build version of the app is on port 8500 "build.domain.com". The application is an Angular application however when I go to load the Angular app it loads on port 4200 or it says 8500 is in use. So currently I am loading that in express like so: // Build Application - In Development var appbuild = express(); appbuild.get('/', function (req, res){ res.sendFile('/app/build/myapp/src/index.html', { root: '.' }) }); var port = 8500; appbuild.listen(port); console.log('Build App Listening on port', port); So my question is in Express how can I instead of writing sendfile command make it launch the angular app in...

Angular / Firestore - What's the best way to check the User ID in multiple components? I have an 'authservice.ts' file where I try to manage user auth style things. However, in each of my components, I'm always subscribing to the user to get the user ID. The user ID is then used inside my Firestore functions to query data where the user ID is referenced inside collection and document paths. Is there a more 'fluent' way of achieving the same thing? Or is this approach actually suitable? Below are the examples of the auth service and a component file that references the auth service. auth-service.ts ... user: Observable<firebase.User>; ... constructor() { this.user = afAuth.authState; } Any One Of My Components.ts ... private _subscription: Subscription; ... ngOnInit() { this.subscribeToUser(); } subscribeToUser() { this._subscription = this.authService.user.subscribe(user => { if (user) { this.userID = user.uid; th...
