Angular Zone Errors in ASP.NET MVC Application - asp.net-mvc

I'm attempting to merge an angular and MVC application together. I'm just trying it on a blank MVC app for beginning purposes by following instructions from a course on pluralsight. However, I'm getting the following error in the console when I try to use the my app tags to test the functionality.
Pricing:56 Error: (SystemJS) XHR error (404 Not Found) loading

Looks like it's obviously related to the zone.js file, but I can't figure this out for the life of me.

Angular <mat-expansion-panel-header> does not expand

I am learning Angular and using Material for Angular for styling. For some reason the mat-accordian isn't working for me.
<mat-accordion>

I've tried reading other posts on stack overflow but nothing has seemed to work.
I tried installing with
import {MatExpansionModule} from '#angular/material/expansion';
but this doesn't work. The accordion is just forever open. Does anyone with Angular experience know where I am going wrong?
Solved: If you install using the default installation and there are peer dependencies it will install an earlier version of Angular Material.
To Fix the issue I uninstalled Angular globally, cleared the cache, then reinstalled, and was able to resolve the dependency conflicts and install the latest version.

Angular 12 Material shows cannot read property errorstate undefined of MatFormField

This is the simple HTML that I have written for single page web app
<div class="bg">
<h1 class="faq_heading">Frequently Asked Questions</h1>
<div class="search">
<mat-form-field class="search_input">
<input type="text" placeholder="Search" class="search_input" matInput [(ngModel)]="inp" (keyup)="onKey($event)" />
</mat-form-field>
<mat-form-field>
<mat-label>Categories</mat-label>
<mat-select class="dropdown" placeholder="Categories">
<mat-option value="Default">Default</mat-option>
</mat-select>
</mat-form-field>
<img src="../assets/images/search.svg" alt="" class="search_img" />
</div>
</div>
There is nothing much in the component.ts file just the basic template and required import statements
Following is the app.module.ts
import { NgModule } from "#angular/core";
import { BrowserModule } from "#angular/platform-browser";
import { MatFormFieldModule } from "#angular/material/form-field";
import { AppRoutingModule } from "./app-routing.module";

As you can see there is not much in the code as I have just started the development , but I am already getting errors in basic templates direct from the docs.
How to handle these errors?
(please note that I am new to angular material, if possible just mention some details around the answer)
Here is the package.json

Import and declare the MatInputModule in the module file solve the issue
....
import {MatInputModule} from '#angular/material/input';
#NgModule({
...
,
imports: [
...
MatInputModule,
],
providers: [
....
]
})
export class MyModule {}
I hade same problem, but when changed to this, issue fixed:
<mat-form-field appearance="fill">
<mat-label>Status</mat-label>
<mat-select>
<mat-option *ngFor="let status of ['active', 'inactive']" [value]="status">
{{status}}
</mat-option>
</mat-select>
</mat-form-field>
I had the same problem, but I solved it adding an ngIf in the mat-form-field tag.
<mat-form-field appearance="fill" *ngIf="role$ | async as roles">
<mat-label>Select a role</mat-label>
<mat-select formControlName="codeRole">
<mat-option *ngFor="let r of roles" [value]="r.code>
{{r.description}}</mat-option>
</mat-select>
</mat-form-field>

Why does http request failed to load resource when using Angular in localhost?

I have an ASP.NET MVC project which uses ASP.NET WebAPI along with Angular for UI components. I'm fairly new to Angular so please bear with me. Below are the config files inside my project.

Also in my WebApiConfig.cs, inside static Register method, I also update routeTemplate as below.
// Web API routes
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);
My issue is that, when I run the application from Visual Studio 2017 on http://localhost:5653; I get Failed to load resource: the server responded with a status of 400 (Bad Request)
When I looked at the browser's console, this is what I got,
I test the http request directly in my browser's address bar http://localhost:56534/api/MoC/GetStatuses, and it gives me the json data that I need. So, there's no problem in WebAPI side.
I found this SO post and, tried to follow Praveen M answer but it didn't worked for me.
Why did I get (400) bad request?, Did I miss an important configuration in my app.routing.ts?
Please, anyone here with a kind heart can spare me a coin?
Try changing:
providers: [{ provide: APP_BASE_HREF, useValue: '/' }, ChangeService]
to just:
providers: [ChangeService]
Well, after banging my head on the wall. I found the culprit of the issue. It's a stupid mistake of mine. The issue isn't on the http request neither related to my localhost. It was one of the component metadata templateUrl. I have mistakenly declare it like this templateUrl: '<span>Hello</span>' instead of just template: '<span>Hello</span>'
That's why the application throws exception because the component template is in bad form http://localhost:56534/%0A%20%20%20%20

Why doesn't my data render in my Ionic 2 views?

I'm working an on an Ionic 2 project and my front end code renders as I would expect it on Android and web but by all accounts nothing renders correctly on iOS.
I'm using Xcode 8.0 with an iPhone 6 version 9.3.4 and Mac version 10.12

This is how it looks on web/Android:
Here is what you see on iOS:
After 10 hour of work I'm pretty certain that iOS doesn't like the change in scope represented by 'self' instead of 'this' within the query promise. Because of this I'm unable to render the data on the client.
The query returns an A+ promise and as far as I know, there is no way to resolve the promise so that the query result stands outside of the promise so that we can use 'this'. I could be totally wrong but I saw nothing in the 'Promise Resolution Procedure' that indicated otherwise.
There was a problem with the polyfills and Angular 2 being recognized on the iOS web browser.
For newbies, I'll be detailed in my answer.
First find the iOS console log:
1) Open Safari
2) Load (play button) the app via Xcode
3) Go to the develop menu
4) Select your device
5) Right before the app finishes loading you will see an option to go to your app. Do so.
From the hints in the logs I found the real error. After a search I added:
<script src="https://cdn.polyfill.io/v2/polyfill.min.js?features=Intl.~locale.en"></script>
to the head of my index.html above
<script src="cordova.js"></script>.

templateUrl in Angular2 Component not loading URL

this is my Component
import { Component, OnInit } from '#angular/core';
#Component({
selector: 'homeView',
templateUrl: '/home/home'
})
export class HomeViewComponent implements OnInit {
ngOnInit(): void {}
}
I am using AngularJS 2 with TypeScript 1.8.5 and trying to create component that will load template from Controller Action.
I am getting this error
main.bundle.js:667 Uncaught Error: Cannot find module ".//home/home"
I also tried it with home/home, the error is almost the same
main.bundle.js:667 Uncaught Error: Cannot find module "./home/home"
Error is not compile time error however - it pops up in browser console when page and the component is being loaded
So as you can see i dont want to load static template like home.template.html - that is working correctly. I want to load an HTML template from asp.net MVC Controller Action. I am not even hitting the debug point in the HomeController Home action.
Is there any way to make this work ? Seems like Angular keeps inserting this './' sign. Is there a way to configure this ? I ve read several tutorials on angular2 + mvc and it seems that this should be possible, but for some reason its not working for me.
My app.routes.ts
import {Routes} from "#angular/router";
import {MainViewComponent} from "../views/main-view/main-view.component";

import {HomeViewComponent} from "../views/home-view/home-view.component";
export const ROUTES:Routes = [
// Main redirect
{ path: '', redirectTo: 'mainView', pathMatch: 'full'},
// App views
{path: 'mainView', component: MainViewComponent},
{path: 'minorView', component: MinorViewComponent},
{path: 'homeView', component: HomeViewComponent}
// Handle all other routes
//{path: '**', component: MainViewComponent }
];

App is built using webpack
main.browser.ts
import {platformBrowserDynamic} from "#angular/platform-browser-dynamic";
import {AppModule} from "../src/app/app.module";
/*
* Bootstrap Angular app with a top level NgModule
*/
platformBrowserDynamic().bootstrapModule(AppModule)
.catch(err => console.error(err));
So, after what seemed like an eternity I finally got the the bottom of this.
The problem was in webpack using angular2-template-loader.
This module is responsible for inlining html template. In other words, it will do a require (using your templateUrl) behind the scenes on the template tag of your component. This, of course, breaks the functionality if you are using actual URLs as templateUrl and not PATHs, therefore the template is not there.
Based on what i read, it seems like the authors wont support this in the future. (If template is not found -> try to load it from URL)
More info here - https://github.com/angular/angular-cli/issues/1605
So, basically I just removed this component from config file :
webpack.config.js
BEFORE
module: {
loaders: [
{
test: /\.ts$/,
loaders: ['awesome-typescript-loader', 'angular2-template-loader']
},
{
test: /\.css$/,
loader:
AFTER
module: {
loaders: [
{
test: /\.ts$/,
loaders: ['awesome-typescript-loader']
},
{
test: /\.css$/,
loader:
