I have set up an Angular SPA with Visual Studio 2017 which enables server-side pre-rendering. However, I discovered my app does not run if I add an Http request. Notice that, if there is no Http request or I disabled pre-rendering and keep Http request everything is fine. Here some parts of my code are following:
index.cshtml
@{
ViewData["Title"] = "Home Page";
}
<app asp-prerender-module="ClientApp/dist/main-server">Loading...</app>
<script src="~/dist/vendor.js" asp-append-version="true"></script>
@section scripts {
<script src="~/dist/main-client.js" asp-append-version="true"></script>
}
startup.cs
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}");
routes.MapSpaFallbackRoute(
name: "spa-fallback",
defaults: new { controller = "Home", action = "Index" });
});

@Injectable()
export class GetCustomerInfoService {

}
}
test.component.ts
constructor(private customerInfo: GetInfoService) {
this.customerInfo.getResults().subscribe(result => {
console.log(result);
});
}
The error I am getting:
An unhandled exception occurred while processing the request. NodeInvocationException: Uncaught (in promise): ReferenceError: XMLHttpRequest is not defined ReferenceError: XMLHttpRequest is not defined
Any idea to fix the above issue?
