Angular – Concepts, Code and Collective Wisdom

NOTE: All GitHub repositories and SatckBlitz sample apps used in this course have been updated to use (and tested with) Angular v8.

This course focuses on the core concepts of Angular.  Particular attention is given to the following areas:

RxJS Observables – learn about Reactive Programming in general, and then the specifics about the RxJS library that Angular uses with HTTP, forms, and routing.  Observables, operators, and Subjects are all covered.

Change Detection – although this is at the heart of Angular, it is not widely understood. I’ll explain all aspects of change detection. (Many of the Angular questions I’ve answered on StackOverflow are due to a lack of understanding of how change detection works.)

Dependency Injection – I’ll explain how this feature automatically manages creating services for you, by simply injecting the desired services into class constructors.

Data Binding – I’ll describe and demonstrate all of the different binding types in Angular, but more importantly, I’ll illustrate (with detailed pictures) how the bindings actually work  i.e., the component and DOM interactions.  I’ll also examine the common sources of confusion developers have when binding using JavaScript reference types in Angular apps. 

Inter–Component Communication and Data Flow – learn how to manage data flow through your Angular application, and how to insert logic hooks that trigger when data becomes available or when data changes.
