API integration in angular with http

In these example, we will learn how to integrate api in angular with example,
we will see how to integrate http get, and post method with actual api.
Api integration is important during development. because we will need to integrate backend services. this video will help you to integrate backend services in angular. we have few http methods like get post put patch delete.
with these get and post method example in angular, you can intgegrate any type of in backend service in your angular code

Most front-end applications need to communicate with a server over the HTTP protocol, to download or upload data and access other back-end services. Angular provides a client HTTP API for Angular applications, the HttpClient service class in @angular/common/http.

How to Use HttpClient?
It can be injected in other services and components. It exports methods for making HTTP Ajax requests such as get(), post(), put(), and delete() and return http responses with various types such as json, text and blob.

HttpClient provides many benefits such as testability, typed request and response objects, request and response interception, Observable APIs, and streamlined error handling.

The methods of HttpClient are based on RxJS observables, so we need to be aware of these points when using them:

You need to subscribe to the observable returned from the method to actually send the http request to the server,
If you subscribe multiple times to the returned observable, multiple HTTP requests will be sent to the server,
The returned observable is a single-value stream which means it will emit only one value and complete.
