Angular 9/8 Ajax Get and Post Requests Example
In this post we will give you information about Angular 9/8 Ajax Get and Post Requests Example. Hear we will give you detail about Angular 9/8 Ajax Get and Post Requests ExampleAnd how to use it also give you demo for it if it is necessary.
In this post, we’ll create a simple example with Angular 9/8 and
HttpClient that sends Ajax Get and Post requests to fetch and post data from/to a backend server.
The server can be either your own server or a third-party server.
In our case, we’ll be using a third-party server.
We assume you already have a project ready and Angular CLI installed.
You can also simply use the online Stackblitz IDE if you just want to experiment with the code and don’t want to set up a development environment for Angular, yet!
What is Ajax?
Ajax was the first step into building modern single page apps or SPAs.
Modern libraries and frameworks, like Angular, make building SPAs simpler.
Http GET and POST Requests?
The GET method of http is used to retrieve a resource from a server while POST is used to create and update data in the server.
HttpClient is a built-in service for sending http requests in Angular. It’s built on top of the
XMLHttpRequest interface available in modern and legacy web browsers.
HttpClientModule is the module that exports the
HttpClient service, so you’ll need to import it in your project.
src/app/app.module.ts file and update it as follows:
We simply need to import
@angular/common/http and add it to the
imports array of
Generate an Angular Service
In your terminal, simply execute the following command from inside your project’s folder:
$ ng generate service http
You’ll get the files for your service with some basic code.
Go to the
src/app/http.service.ts file and import
HttpClient using the constructor of your http service:
That’s it! We are ready to send get and post requests in our app.
Sending an Ajax GET Request
Let’s start with defining a service method for sending a get request to the server to fetch some data:
Let’s suppose our endpoint returns the following data:
Sending an Ajax POST Request
Next, let’s define a method for sending a post request:
You next need to inject
HttpService in your component(s) and call the methods but to actually send the requests to the server you need to subscribe to the RxJS observables returned from the defined methods. For example:
This will work provided that you have injected your service as
httpService in your component’s constructor.
