![]() ![]() ![]() In this how-to post, we’ve seen how to create a service in Angular and use HttpClient to send HTTP requests to REST API backends and finally display the data returned from the API using the ngFor directive. In both cases, we use the httpHeaders configuration option provided by angular HttpClient to add the headers. The second way is to use the HTTP interceptor to intercept all the Requests and add the Headers. ![]() One, we add the HTTP Headers while making a request. Join the community of millions of developers who build compelling user interfaces with Angular. There are two ways by which we can add the headers. In this article, I will describe these innovations. On this occasion, the interceptor concept was also revised. For version 15, the Angular team has now adapted it for the new standalone components. The new Angular HTTP Client is a great evolution when compared to the previous HTTP client: its more user-friendly and helps to improve the type safety of our code. The Angular HttpClient has features of testability features, typed request and response objects, request and response interception, Observable APIs, and streamlined error handling. Without any doubt, the HttpClient is one of the best-known services included in Angular. You can reach out to or follow the author via his personal website, Twitter, LinkedIn and Github. Angular is a platform for building mobile and desktop web applications. The Angular 14 HttpClient simplified the client HTTP API on the XMLHttpRequest interface exposed by browsers. Here, we suppose that our data elements have a name attribute. Now head over to your Angular application root directory by running the following command: cd my-app & ng start // starts angular application. Open the src/app/ file and update as follows: import This tutorial assumes that you have the Angular 11 application installed in your local machine. You need to have Node, NPM and Angular CLI and initialized an Angular project. For usage information, see the HTTP Client guide. Includes testability features, typed request and response objects, request and response interception, observable APIs, and streamlined error handling. An Angular service is simply a TypeScript class that you can inject in other services or components using the Angular dependency injector. Starting from the 5th version of Angular, the angular/http module was deprecated for the new. Implements an HTTP client API for Angular apps that relies on the XMLHttpRequest interface exposed by browsers. ![]()
