What You'll Learn in this Angular 9 Tutorial?

We'll learn by example:

  • how to send GET requests with URL query strings and parameters
  • and process HTTP responses from REST API servers in your Angular 9 application using Angular Httplient for fetching and consuming JSON data,
  • how to do error handling for HTTP errors using the RxJS throwError() and catchError() operators,
  • how to retry failed HTTP requests in poor network connections and cancel pending requests using the RxJS retry() and takeUntil() operators,
  • and finally how to deploy the application to Firebase Hosting using the latest Angular 8.3+ features.

We'll also see how to use Angular 9 services and RxJS Observables, and learn how to set up Angular 9 Material in our project and style the UI with Material Design components.

We'll see how to use the new ng deploy feature in Angular 8.3+ to easily deploy your Angular 9 application from the command-line to Firebase hosting.

Angular 9 is finally released, and comes with various new features and improvements particularly the new Ivy renderer.
