import { HttpService } from '@hapiness/http';

@Lib()
class LibWithHttpCalls {
    constructor(private _http: HttpService){}
    
    crawlWebPage(): void {
        this._http.get('http://www.google.fr').subscribe(
            (data) => {
        
                if (data.response.statusCode === 200) {
                    console.log(data.body); // Show the HTML for the Google homepage.
                }
            },
            (err) => console.error(err) // Show error in console

import '@hapiness/http/observable/add/validateResponse';

@Lib()
class LibWithHttpCalls {
    constructor(private _http: HttpService){}
    
    crawlWebPage(): void {
        this._http.get('http://my-api/data')
            .validateResponse(MySchema)
            .subscribe(
                (data) => console.log(data),
                (err) => console.error(err) // Show error in console
