Just do `ng serve --live-reload false` or `ng serve --no-live-reload`

It used to not work, [this PR][1] solved it.


  [1]: https://github.com/angular/angular-cli/pull/3952

serve your application with this command:

    ng serve --live-reload=false

if you want to run your application in *prod mode*, use following command

    ng serve --source-map=false --aot --prod --live-reload=false

I think you only want to disable the *rebuild on change* option

Just try:

    $ ng serve --watch=true|false



The solution for this is to upgrade the version of the CLI you are using.  The CLI now uses in memory for the build process and is no longer writing to disk.  This helps with the antivirus/disk write issue. 

I need to launch two distinct processes on a docker container which requires two terminals.What is the best way to achieve this?

When serving my app with the Angular cli, how do I disable auto-reload?

`ng --help` mentions the `--live-reload` option, but I can&#39;t make it work.

`ng serve --live-reload=false` or `ng serve --live-reload false` do not work

EDIT : it seems to be a bug https://github.com/angular/angular-cli/issues/1755

I am trying to test my component with angular 2 final, but I get an error because the component uses the `routerLink` directive. I get the following error:

&gt; Can&#39;t bind to &#39;routerLink&#39; since it isn&#39;t a known property of &#39;a&#39;.

This is the relevant code of the `ListComponent` template

    &lt;a 
      *ngFor=&quot;let item of data.list&quot; 
      class=&quot;box&quot;
      routerLink=&quot;/settings/{{collectionName}}/edit/{{item._id}}&quot;&gt;

And here is my test.

    import { TestBed } from &#39;@angular/core/testing&#39;;
    
    import { ListComponent } from &#39;./list.component&#39;;
    import { defaultData, collectionName } from &#39;../../config&#39;;
    import { initialState } from &#39;../../reducers/reducer&#39;;
    
    
    const data = {
      sort: initialState.sort,
      list: [defaultData, defaultData],
    };
    
    describe(`${collectionName} ListComponent`, () =&gt; {
      let fixture;
      beforeEach(() =&gt; {
        TestBed.configureTestingModule({
          declarations: [
            ListComponent,
          ],
        }).compileComponents(); // compile template and css;
        fixture = TestBed.createComponent(ListComponent);
        fixture.componentInstance.data = data;
        fixture.detectChanges();
      });
    
      it(&#39;should render 2 items in list&#39;, () =&gt; {
        const el = fixture.debugElement.nativeElement;
        expect(el.querySelectorAll(&#39;.box&#39;).length).toBe(3);
      });
    });

I looked at several answers to similar questions but could not find a solution that worked for me.


Angular 2 unit testing components with routerLink

I am trying to test angular2 two-way binding for control `input`. Here is the error:

angular2 testing: Can&#39;t bind to &#39;ngModel&#39; since it isn&#39;t a known property of &#39;input&#39;

In my Angular 2 app when I scroll down a page and click the link at the bottom of the page, it does change the route and takes me to the next page but it doesn&#39;t scroll to the top of the page. As a result, if the first page is lengthy and 2nd page has few contents, it gives an impression that the 2nd page lacks the contents. Since the contents are visible only if a user scrolls to the top of the page.

I can scroll the window to the top of the page in ngInit of the component but, is there any better solution that can automatically handle all routes in my app?

Angular 2 Scroll to top on Route Change

I have Angular 2.0.0 app generated with angular-cli. 

When I create a component and add it to `AppModule`&#39;s declarations array it&#39;s all good, it works. 

I decided to separate the components, so I created a `TaskModule` and a component `TaskCard`. Now I want to use the `TaskCard` in one of the components of the `AppModule` (the `Board` component).

AppModule:

    import { BrowserModule } from &#39;@angular/platform-browser&#39;;
    import { NgModule } from &#39;@angular/core&#39;;
    import { FormsModule } from &#39;@angular/forms&#39;;
    import { HttpModule } from &#39;@angular/http&#39;;
    
    import { AppComponent } from &#39;./app.component&#39;;
    import { BoardComponent } from &#39;./board/board.component&#39;;
    import { LoginComponent } from &#39;./login/login.component&#39;;
    
    import { MdButtonModule } from &#39;@angular2-material/button&#39;;
    import { MdInputModule } from &#39;@angular2-material/input&#39;;
    import { MdToolbarModule } from &#39;@angular2-material/toolbar&#39;;
    
    import { routing, appRoutingProviders} from &#39;./app.routing&#39;;
    import { PageNotFoundComponent } from &#39;./page-not-found/page-not-found.component&#39;;
    
    import { UserService  } from &#39;./services/user/user.service&#39;;
    import { TaskModule } from &#39;./task/task.module&#39;;
    
    
    @NgModule({
      declarations: [
        AppComponent,
        BoardComponent,// I want to use TaskCard in this component
        LoginComponent,
        PageNotFoundComponent
      ],
      imports: [
        BrowserModule,
        FormsModule,
        HttpModule,
        MdButtonModule,
        MdInputModule,
        MdToolbarModule,
        routing,
        TaskModule // TaskCard is in this module
      ],
      providers: [UserService],
      bootstrap: [AppComponent]
    })
    export class AppModule { }

TaskModule:

    import { NgModule } from &#39;@angular/core&#39;;
    import { TaskCardComponent } from &#39;./task-card/task-card.component&#39;;
    
    import { MdCardModule } from &#39;@angular2-material/card&#39;;
    
    @NgModule({
      declarations: [TaskCardComponent],
      imports: [MdCardModule],
      providers: []
    })
    export class TaskModule{}

The whole project is available on https://github.com/evgdim/angular2 (kanban-board folder)

What am I missing? What do I have to do to use `TaskCardComponent` in `BoardComponent`?

Use component from another module

In typescript, using Angular 2, I need to import two classes with the same name, but lying in different paths.

The project is quite too big that I find it hard to change the exported class names.

Is there any way to alias the imported classes,

    import {Class1} from &#39;../location1/class1&#39;
    import {Class1} from &#39;../location2/class1&#39;

Import two exported classes with the same name

https://github.com/angular/angular-cli#proxy-to-backend here is an instruction how to do proxying to backend. I did everything step by step and still requests aren&#39;t proxied.

8080 - my Express backend
4200 - my Angular2 frontend

In Angular2 project I have file ```proxy.conf.json``` with content like this:

    {
      &quot;/api&quot;: {
        &quot;target&quot;: &quot;http://localhost:8080&quot;,
        &quot;secure&quot;: false
      }
    }

In Angular2 package.json I changed ```start``` procedure to ```&quot;start&quot;: &quot;ng serve --proxy-config proxy.conf.json&quot;```

When I type inside commander ```npm start``` then at the start I can see ```Proxy created: /api -&gt; http://localhost:8080```. Well, so far is good I guess.

I&#39;m trying to send a request (Angular2)

      constructor(private http: Http) {
        this.getAnswer();
      }
    
      getAnswer(): any {
        return this.http.get(&quot;/api/hello&quot;)
          .subscribe(response =&gt; {
            console.log(response);
          })
      }

I&#39;m getting an error that ```http://localhost:4200/api/hello 404 (Not Found)```. As we can see, nothing has been proxied. Why? Did I do something wrong?

To be clear. When I go manually to ```http://localhost:8080/hello```, all works fine. There is nothing to look for in backend side.

Angular-CLI proxy to backend doesn&#39;t work

`ng serve` is not building to the path that I have set in my angular-cli.json in `apps[0].outDir`.

`ng build` works correctly and builds to the path that I have specified.

Where does `ng serve` output files to?

&gt; `ng serve` serves an Angular project via a development server

&amp;nbsp;

&gt; `npm start` runs an arbitrary command specified in the package&#39;s &quot;start&quot;
&gt; property of its &quot;scripts&quot; object. If no &quot;start&quot; property is specified
&gt; on the &quot;scripts&quot; object, it will run node server.js.

It seems like `ng serve` starts the embedded server whereas `npm start` starts the Node servers.

Can someone throw some light on it?

When to use &#39;npm start&#39; and when to use &#39;ng serve&#39;?

Is it possible to add a global CSS file to Angular 2?
At the moment I have many different components that have the same button styling - but each of the components have their own CSS file with the styling.  This is frustrating for changes.

I read somewhere on Stack Overflow to add:

    import { ViewEncapsulation } from &#39;@angular/core&#39;; //add this

    @Component({
      selector: &#39;app-root&#39;,
      templateUrl: &#39;./app.component.html&#39;,
      styleUrls: [&#39;./app.component.css&#39;],
      encapsulation: ViewEncapsulation.None            //add this
    })

So I added the ViewEncapsulation lines in the root component, then added the CSS styling to the root app CSS (app.component.css) and removed the CSS styling from individual component CSS files, and it did not work.

Surely there is a way to add a global CSS file?  Do I need to add something to the individual components to make them access the global CSS file?
