Upgrading From Angular 4 To 7 Causing Some Problems

hey i have upgraded my project from angular 4 to angular 7 and some of the services, modules are deprecated. this is my app.module.ts @NgModule({ declarations: [AppComponent],

Solution 1:

You have to use new packge from @angular/common/http like

import { HttpClientModule } from"@angular/common/http";
import { HttpClient } from"@angular/common/http";

So mostly you will use HttpHeaders to construct your ajax header like params formdata etc...

Headers -> HttpHeaders

Response -> HttpResponse

RequestOptions, RequestOptionsArgs are remove and you have to use HttpParams
