Questions

I'm trying to simplify components code in ui/components folder. They are all using Service1, Service2 and common variables. I Thought into TS mixins to provide them all with SharedModulesModule (which currently, they are all using) but I ran into 2 issues first, I can't import a service within a TS mixin second, I don't think they all will always consume SharedModulesModule.

So, I created a Handler class with the @Directive decorator, in its constructor I'm providing Injector to provide the service to anyone extending the Handler class without the need to redeclare it. Not sure if this approach is good.

Observables vs Promises, not sure which one to pick when working with Firebase services.
I have a bunch of Observers in a Handler helper class to reduce code in components, that doesnt seems to be right but I'm not sure how to reduce observers code size
Login set a localStorage variable to know if the user already tried to log in to call for the firebase user information, all of firebase authentication calls are taking more than 30 seconds after cache is cleared. I want to avoid using localStorage, how can I do this if fibebase is taking 30secs to 1min to return a call back saying if the user is authenticated or not.
I have a verify email, and a getSession method, I want to run an Observer for one, and a different observer form another. Basically, 2 subscribtios. This, to use the Observer already created and have a clean solution. The reason is beacuse I want to display certain notifications once one finished, and different actions once the other finishes, they need to be sequencial. Basically, if the user get verified correctly, I want to notify that, then, I want to get the SSO session and route the user into the application.
Should I use defer to add logic before the subscripcion of a observable?
How should a spinner be?
The firebase uncaught exception always bubbles up/propagates (what is the right word?) to the angular ErrorHandler.This solution is right?: https://stackoverflow.com/questions/69270802/uncaught-in-promise-firebaseerror
I dont fully understand "composition" vs inheritance. I had this { provide: AbstractFirebaseAuthHandler, useClass: HandlerService } and "public firebaseAuthHandler: AbstractFirebaseAuthHandler" in a component "A". I was expecting to inherit HandlerService properties inside the "A" component without the need of using the "extend" word. But I was not inheriting the properties. To access them I needed de constructor firebaseAuthHandler variable.
In ErrorHandlerService i'm using injector to avoid circular dependency, not sure why this is. Why I'm I getting circular dependency? why can't I use inject instead?
I can't provide store using provideStore() in main, not sure why but It says that StoreModule is not provided (angular is not the one failing, it fails in runtime)
In the HTML of login component I'm calling a service Subject property, is this a good practice?
How to test effects?

Adding capabilities to your workspace

Nx supports many plugins which add capabilities for developing different types of applications and different tools.

These capabilities include generating applications, libraries, etc as well as the devtools to test, and build projects as well.

Below are our core plugins:

Angular
- ng add @nx/angular
React
- ng add @nrwl/react
Web (no framework frontends)
- ng add @nrwl/web
Nest
- ng add @nrwl/nest
Express
- ng add @nrwl/express
Node
- ng add @nrwl/node

There are also many community plugins you could add.

Generate an application

Run ng g @nx/angular:app my-app to generate an application.

You can use any of the plugins above to generate applications as well.

When using Nx, you can create multiple applications and libraries in the same workspace.

Generate a library

Run ng g @nx/angular:lib my-lib to generate a library.

You can also use any of the plugins above to generate libraries as well.

Libraries are shareable across libraries and applications. They can be imported from @dietas-adrian-nx-workspace/mylib.

Development server

Run ng serve my-app for a dev server. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.

Code scaffolding

Run ng g component my-component --project=my-app to generate a new component.

Build

Run ng build my-app to build the project. The build artifacts will be stored in the dist/ directory. Use the --prod flag for a production build.

Running unit tests

Run ng test my-app to execute the unit tests via Jest.

Run nx affected:test to execute the unit tests affected by a change.

Running end-to-end tests

Run ng e2e my-app to execute the end-to-end tests via Cypress.

Run nx affected:e2e to execute the end-to-end tests affected by a change.

Understand your workspace

Run nx graph to see a diagram of the dependencies of your projects.
