https://youtu.be/wB-GlKi4f4c,Portal is where an interactive portal has been developed. e.g. https://dev.telstra.com/,Other notes were made to support future research.,#api #rest api #restful api #asp.net api #api tutorial #consume api

This sends an HTTP DELETE request to the JSONPlaceholder api which is a fake online REST api that includes a /posts/1 route that responds to DELETE requests with a HTTP 200 OK response. When the response is received the Angular component displays the status message ‘Delete successful’.

ngOnInit() {
   this.http.delete('https://jsonplaceholder.typicode.com/posts/1')
      .subscribe(() => this.status = 'Delete successful');
}

The object passed to the request subscribe() method contains two callback functions, the next() function is called if the request is successful and the error() function is called if the request fails.

ngOnInit() {
   this.http.delete('https://jsonplaceholder.typicode.com/invalid-url')
      .subscribe({
         next: data => {
            this.status = 'Delete successful';
         },
         error: error => {
            this.errorMessage = error.message;
            console.error('There was an error!', error);
         }
      });
}

To set or update headers on an existing HttpHeaders object call the set() method, e.g. const headers = new HttpHeaders().set('Authorization', 'Bearer my-token')

ngOnInit() {
   const headers = {
      'Authorization': 'Bearer my-token',
      'My-Custom-Header': 'foobar'
   };
   this.http.delete('https://jsonplaceholder.typicode.com/posts/1', {
         headers
      })
      .subscribe(() => this.status = 'Delete successful');
}

In this post I will show you the usage of useEffect hook. Which is really really important if you are a reactjs dev. So if you are interested to learn it, continue reading....,Now I will show you how fetch some data's from an api using useEffect hook.,Here in this code, I just have a button. Which will increment the current value of our state. And in useEffect I have put the state variable as a dependency of the hook. So what will be happened here?,That's all now the whole code will be look like that ->

import React, {
   useEffect
} from 'react';
