Thanks for your content. Some constructive criticism:

- this is a RxJS / Reactive programming video. However, the first 6 minutes (almost 50% of the video) are about writing CSS.

In the future, would be better if you prepare the CSS solution beforehand and just give a 60 seconds walkthrough the app setup to understand how the UI is put together, and then just jump straight to the main content of the video.

we can add it directly in common interceptor which will handle the all loader on/off, bearer Token and also common Error Handling . Avoid lines of code and repeated code right? . correct me if im wrong . .thanks for your contribution Leela . I have learned alot from your videos.

Hi Leela, Why you did not apply the async pipe directly to the app-loading component like this: <app-loading *ngIf="showLoader$ | async"></app-loading>

How could we do that for a serverless platform like Firebase

I got the errror: ERROR Error: NG0100: Expression has changed after it was checked. Previous value: 'null'. I know solutions may be we need to add changeDetection here. Do any of you face with the same issue liked me?
