Introduction to RxJS Observables and Angular
This article has been updated to the latest version Angular 17 and tested with Angular 16. The content is likely still applicable for all Angular 2 + versions.
You can find a updated version of this screencast here.
Below is a screencast of an introduction to RxJS Observables and how they integrate into Angular. First we will cover what Observables are and how RxJS helps us. Next we will learn how to use Observable Operators and create a Counter UI widget without Angular. Afterwards we will create a small Angular app to search the YouTube API using Observables.
You can find the source code by clicking the demo button below. Please feel free to leave feedback in the comments below. At the time of this recording Angular was in beta-6 but this still applies to the current version of Angular Afterwards check out my other post on Angular Observable Data Services.
