      Angular HTTP - Abdelfattah Ragab

      Introduction

      In this book, I explain everything you need to know about connecting to backend Rest APIs from your Angular application.

      In this book, I will show you how to invoke different methods like GET, POST, and the like, how to use interceptors to inject an authentication token into every outgoing request, and much more.

      By the end of this book, you will be able to call Rest APIs from your Angular application in any scenario.

      Let us get started.

      The HttpClient is provided with the help function provideHttpClient, which most applications include in the application providers in app.config.ts.
