/**
|
|
* There is an ajax operator on the Rx object.
|
|
*
|
|
* It creates an observable for an Ajax request with either a request object with
|
|
* url, headers, etc or a string for a URL.
|
|
*
|
|
*
|
|
* ## Using ajax() to fetch the response object that is being returned from API.
|
|
* ```ts
|
|
* import { ajax } from 'rxjs/ajax';
|
|
* import { map, catchError } from 'rxjs/operators';
|
|
* import { of } from 'rxjs';
|
|
*
|
|
* const obs$ = ajax(`https://api.github.com/users?per_page=5`).pipe(
|
|
* map(userResponse => console.log('users: ', userResponse)),
|
|
* catchError(error => {
|
|
* console.log('error: ', error);
|
|
* return of(error);
|
|
* })
|
|
* );
|
|
*
|
|
* ```
|
|
*
|
|
* ## Using ajax.getJSON() to fetch data from API.
|
|
* ```ts
|
|
* import { ajax } from 'rxjs/ajax';
|
|
* import { map, catchError } from 'rxjs/operators';
|
|
* import { of } from 'rxjs';
|
|
*
|
|
* const obs$ = ajax.getJSON(`https://api.github.com/users?per_page=5`).pipe(
|
|
* map(userResponse => console.log('users: ', userResponse)),
|
|
* catchError(error => {
|
|
* console.log('error: ', error);
|
|
* return of(error);
|
|
* })
|
|
* );
|
|
*
|
|
* ```
|
|
*
|
|
* ## Using ajax() with object as argument and method POST with a two seconds delay.
|
|
* ```ts
|
|
* import { ajax } from 'rxjs/ajax';
|
|
* import { of } from 'rxjs';
|
|
*
|
|
* const users = ajax({
|
|
* url: 'https://httpbin.org/delay/2',
|
|
* method: 'POST',
|
|
* headers: {
|
|
* 'Content-Type': 'application/json',
|
|
* 'rxjs-custom-header': 'Rxjs'
|
|
* },
|
|
* body: {
|
|
* rxjs: 'Hello World!'
|
|
* }
|
|
* }).pipe(
|
|
* map(response => console.log('response: ', response)),
|
|
* catchError(error => {
|
|
* console.log('error: ', error);
|
|
* return of(error);
|
|
* })
|
|
* );
|
|
*

* ## Using ajax() to fetch. An error object that is being returned from the request.
