   Head over to [http://dot.net](http://feeds.hanselman.com/~/t/0/0/scotthanselman/~dot.net) and check it out. A great aspect of .NET Core is that everything it does is side-by-side. You can work with it without affecting your existing systems. Be sure also explore the [complete .NET Downloads Page](http://feeds.hanselman.com/~/t/0/0/scotthanselman/~https://www.microsoft.com/net/download) for all the manual downloads as well as SHA hashes


   > The best way to develop with .NET Core on Windows is to download the [Visual Studio official MSI Installer](http://feeds.hanselman.com/~/t/0/0/scotthanselman/~https://go.microsoft.com/fwlink/?LinkId=798481) and the latest [NuGet Manager extension for Visual Studio](http://feeds.hanselman.com/~/t/0/0/scotthanselman/~https://dist.nuget.org/visualstudio-2015-vsix/v3.5.0-beta/NuGet.Tools.vsix). If you don't have Visual Studio already, you can download [Visual Studio Community 2015](http://feeds.hanselman.com/~/t/0/0/scotthanselman/~https://www.visualstudio.com/products/visual-studio-community-vs) for free.


   We'll have documentation and insights on how to moving from ASP.NET 4.x over to ASP.NET Core 1.0 soon, but for now I've collected these resources for folks who are upgrading from previous versions of .NET Core and ASP.NET Core (the framework formerly new as ASP.NET 5).

   **Sponsor:** Build servers are great at compiling code and running tests, but not so great at deployment. When you find yourself knee-deep in custom scripts trying to make your build server do something it wasn't meant to, [give Octopus Deploy a try](http://feeds.hanselman.com/~/t/0/0/scotthanselman/~bit.ly/1W4LRAn).

## Detect breakpoint by use **@angular/cdk**

breakpoint usually is CSS, you write media query for different style for
different view. However, sometime you might want to do that in Javascript
instead of CSS. At this blog, we'll use **@angular/cdk** at
Angular Universal App project.

## First intall **@angular/cdk**

```
"@angular/cdk": "^7.3.3",
```

## Add Layout Module to root angular module

```
import { LayoutModule } from "@angular/cdk/layout";

@NgModule({
  declarations: [AppComponent, HomeComponent],
  imports: [
    BrowserModule.withServerTransition({ appId: "my-app" }),
    RouterModule.forRoot([
      { path: "", component: HomeComponent, pathMatch: "full" },
      { path: "lazy", loadChildren: "./lazy/lazy.module#LazyModule" },
      { path: "lazy/nested", loadChildren: "./lazy/lazy.module#LazyModule" }
    ]),
    TransferHttpCacheModule,
    LayoutModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule {}
```

## Use **@angular/cdk** at Angular component

```
ngOnInit(): void {
    this.breakpointObserver
      .observe(["(min-width: 500px)"])
      .subscribe((state: BreakpointState) => {
        if (state.matches) {
          console.log("Viewport is 500px or over!");
        } else {
          console.log("Viewport is getting smaller!");
        }
      });
  }
```

Following is for someone who one to get quick hello world angular2 running,
the code is reference from angular2's original quickstart GitHub source code and with additional few udpates, all code shows here are at my Github
repository Angular2HelloWorld

**File Structure**

```

+-- .gitignore
+-- index.html
+-- package.json

+-- typings.json
```

### Features

  - HelloWorld Angular2

  - Runtime TypeScript compiler

  - One Html example

  - Css

### `index.html`

index.html is the main page, `my-app` is the section will inject by
angular2 code.

```


    Angular 2 QuickStart



    
     




    


      System.import('app').catch(function(err){ console.error(err); });


  

    Loading...


```

### `package.json`

package.json contains all the dependency modules for this app, just run
`npm install -d`, will install all the npm modules.

```

  "version": "1.0.0",
  "scripts": {
    "start": "tsc && concurrently \"npm run tsc:w\" \"npm run lite\" ",

### `styles.css`

Just a style for this example, later want to try how to use SASS with this
hello world structure.

```
h1 { color: #ffffff; font-family: 'Lato', sans-serif; font-size: 54px; font-weight: 300; line-height: 58px; margin: 0 0 58px; }
body {
    background-color: #333;
}
```

### `systemjs.config.js`

A file from original angular2 quick start example, which bootstrap the
angualr2 code.

```
/**
 * System configuration for Angular 2 samples
 * Adjust as necessary for your application needs.
 */
(function(global) {
  // map tells the System loader where to look for things
  var map = {
    'app':                        'app', // 'dist',
    '@angular':                   'node_modules/@angular',
    'angular2-in-memory-web-api': 'node_modules/angular2-in-memory-web-api',
    'rxjs':                       'node_modules/rxjs'
  };
  // packages tells the System loader how to load when no filename and/or no extension
  var packages = {
    'app':                        { main: 'main.js',  defaultExtension: 'js' },
    'rxjs':                       { defaultExtension: 'js' },
    'angular2-in-memory-web-api': { main: 'index.js', defaultExtension: 'js' },
  };
  var ngPackageNames = [
    'common',
    'compiler',
    'core',
    'http',
    'platform-browser',
    'platform-browser-dynamic',
    'router',
    'router-deprecated',
    'upgrade',
  ];
  // Individual files (~300 requests):
  function packIndex(pkgName) {
    packages['@angular/'+pkgName] = { main: 'index.js', defaultExtension: 'js' };
  }
  // Bundled (~40 requests):
  function packUmd(pkgName) {
    packages['@angular/'+pkgName] = { main: '/bundles/' + pkgName + '.umd.js', defaultExtension: 'js' };
  }
  // Most environments should use UMD; some (Karma) need the individual index files
  var setPackageConfig = System.packageWithIndex ? packIndex : packUmd;
  // Add package entries for angular packages
  ngPackageNames.forEach(setPackageConfig);
  var config = {
    map: map,
    packages: packages
  };
  System.config(config);
})(this);
```

### `tsconfig.json`

Typescript config files.

```
{
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "moduleResolution": "node",
    "sourceMap": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "removeComments": false,
    "noImplicitAny": false
  }
}
```

.gitignore, so you won't check-in extra code to git.

```
.idea
typings/**
node_modules
jspm_packages
link-checker-results.txt
**/*npm-debug.log.*
*.js
*.js.map
_test-output
_temp

!**/*e2e-spec.js
!karma*.js
!protractor*.js
!systemjs.config.js
!typings/typings.d.ts
!wallaby.js
```

### Get code form github

Now, you can get code as following, first clone and download to your local.

```
a:\>git clone https://github.com/keke78ui9/Angular2HelloWorld helloAngular2
Cloning into 'helloAngular2'...
remote: Counting objects: 15, done.

```

Then go to the new folder contains the code

```
a:\>cd helloAngular2
```

```
a:\helloAngular2>npm install -d
