8. New Project Visual Studio: File -> New Project F5 Angular CLI: > ng new <name> > ng serve
9. View Code // XAML <Button Width="75" Height="20" >Search</ Button> <TextBox Height="23" Text="TextBox" Width="120"/> <!-- HTML --> <input type="text" value="text"> <button>Search</button>
10. Model Classes // C# POCO public class Game { public string MatchInfo1 { get; set; } public int FifaId { get; set; } } <!-- TypeScript --> export interface Game { MatchInfo1: string; FifaId: number; }
11. Backend Call // REST API Call -> «Add REST Client» var url = $"{endpointUri}/Game/?countryCode={code}"; var client = new WmAPI.WmAPIClient(url); Game[] result = client.GetAll(); <!-- TypeScript --> -> Convert Swagger to TypeScript Class const url = `${endpointUri}/Game/?countryCode=${code}`; return this.http.get<Game[]>(url);
12. Data Binding // XAML <Label Content="{Binding /MatchInfo1}"/> <ListView ItemsSource="{Binding}" DisplayMemberPath="Description" > <!-- HTML --> {{selectedMatch.GameInfo1}} <a (click)="showDetail(match)" *ngFor="let game of games$ | async"> {{ game.Description }} </a>
13. WPF versus Angular ▪ File new Project ▪ C# ▪ XAML ▪ Controls ▪ User Controls ▪ Resource Dictionaries ▪ Commands ▪ Data Binding ▪ Value Converter ▪ ng new <my-name> ▪ Typescript ▪ HTML ▪ HTML Elements ▪ Components ▪ CSS ▪ HTML Events ▪ Data Binding ▪ Pipe
14. How to start with Angular?
15. Download Visual Studio Code
16. Install VSCode Extensions
17. Get it from: nodejs.org
18. npm install @angular/cli
19. npm install @angular/cli -g
21. Angular CLI ▪ Command line interface for Angular ▪ Build an Angular application ▪ Generate files (Scaffolding) ▪ Execute / run the application ▪ Run unit and e2e tests ▪ Prepare and «optimize» the application for deployment.
22. Module Anatomy of an Angular Application Component person-list Component person-detail Component person-edit PersonService
23. CLI: Generate new app ng new my-app Generate a new app in /my-app ng new my-app --dry-run Report without writing files ng new my-app --skip-install Generate without npm install ng new --style scss Use SCSS instead of CSS ng new my-app --routing Generate app with routing
24. Project structure
25. CLI: Generate Component ng generate <blueprint> Generate component/service, etc. ng g component product-list Generate a component ng g c <name> --spec=false Without unit tests
26. CLI: Serve and build ng serve Serve the app on localhost:4200 ng serve -o Serve the app and open ng build Build in dev mode ng build --prod Build in prod mode

41. Recap ▪ Most of the concepts are similar ▪ Its 2018. Thanks to TypeScript, we do NOT need to be afraid fo JS anymore ▪ Technologies are aligning ▪ But the Web is a different world.
