DotNetDay18 Thomas Gassmann und Bandixen Angular Quick Start

Angular ist das JavaScript Framework, von welchem heute alle sprechen und welches jeder Kunde einsetzen will. In dieser Session lernen Sie die Grundlagen der Web-Entwicklung mit Angular 5 kennen und bekommen einen Überblick über den initialen Setup für den erfolgreichen Start. Nach einer Einführung in die Grundlagen zeigen wir Ihnen, wie sie mit Visual Studio Code und dem Angular Command Line Interface (Angular CLI) sofort loslegen können.

3. Agenda 29.05.2018 Angular Developer Quick Start 4 ▪ Basics of Angular ▪ How to start ▪ Demo
4. 29.05.2018 Angular Developer Quick Start 5
5. Plattform 29.05.2018 Angular Developer Quick Start 6 Dependency Injection Decorators Zones Compile Binding Render Material Mobile Universal CLI Language Service Augury ngUpdate Router Animation i18n
6. Module Anatomy of an Angular Application 29.05.2018 Angular Developer Quick Start 7 Component Component Component Services
7. Component 29.05.2018 Angular Developer Quick Start 8 import { Component } from '@angular/core'; @Component({ selector: 'app-product-list’, template: `<div> <h1>{{ pageTitle }}</h1> </div>` }) export class ProductListComponent { pageTitle: string = 'About'; } <app-product-list></app-product-list>
8. Component and DataBinding 29.05.2018 Angular Developer Quick Start 9 ▪ {{}} : Display the value in the UI ▪ [] : Bind an element-property to a property of your class ▪ () : Bind an element-event to a method of your class ▪ [()] : Bind a property two-way that you don’t have to think whether it’s ([]) or [()], just use the “banana in a box”-mnemonic to get the syntax right
9. Interpolation ( {{...}} ) 29.05.2018 Angular Developer Quick Start 10 @Component({ selector: 'my-app', template: `<h1>Details of {{fullname}}</h1>` }) export class AppComponent { fullname: string = "Lara Croft"; }
10. Property Binding ( [...] ) 29.05.2018 Angular Developer Quick Start 11 @Component({ template: `… <span [hidden]="isUnchanged">changed</span>` }) export class AppComponent { isUnchanged: boolean = true; }
11. Event Binding ( (...) ) 29.05.2018 Angular Developer Quick Start 12 @Component({ template: `… <button (click)="onSave()">Save</button>` }) export class AppComponent { onSave() { // do something } }
12. Two-Way Data Binding ( [(...)] ) 29.05.2018 Angular Developer Quick Start 13 @Component({ selector: 'my-app’, template: `<h1>Details of {{person.fullname}}</h1> <input type="text" [(ngModel)]="person.fullname">` }) export class AppComponent { person: Person = { fullname: 'Lara Croft' }; } interface Person { fullname: string }
13. Service 29.05.2018 Angular Developer Quick Start 14 ▪ A service is a class that gets injected into components ▪ for example a class that encapsulates access to a REST- Api ▪ or to allow a communication between components Component Component Component Service
14. Service 29.05.2018 Angular Developer Quick Start 15 @Injectable() export class ProductService { constructor(private http: HttpClient) { } getProducts(): Observable<Product[]> { ... } }
15. Using a service 29.05.2018 Angular Developer Quick Start 16 import { ProductService } from './product.service'; @Component({ … }) export class ProductListComponent { private service: ProductService; constructor(service: ProductService) { this.service = service; } }
16. Using a service 29.05.2018 Angular Developer Quick Start 17 import { ProductService } from './product.service'; @Component({ … }) export class ProductListComponent { constructor(private service: ProductService) { } }
17. Module 29.05.2018 Angular Developer Quick Start 18 ▪ Every App has at least one module, the Root Module ▪ The module can bundle multiple components ▪ One Component must be bootstrapped for startup Component Component Component Root Module bootstrap
18. Module 29.05.2018 Angular Developer Quick Start 19 @NgModule({ imports: [ BrowserModule, HttpClientModule, FormsModule, AppRoutingModule, ], declarations: [AppComponent], providers: [ProductService], bootstrap: [AppComponent] }) export class AppModule {}
19. How to start?
20. Angular CLI 29.05.2018 Angular Developer Quick Start 21 ▪ 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
21. 29.05.2018 Angular Developer Quick Start 22 npm install <PACKAGE-NAME>
22. 29.05.2018 Angular Developer Quick Start 24 npm install @angular/cli
23. 29.05.2018 Angular Developer Quick Start 25 npm install @angular/cli -g
24. CLI: Generate new app 29.05.2018 Angular Developer Quick Start 27 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
25. CLI: Generate 29.05.2018 Angular Developer Quick Start 29 ng generate <blueprint> Generate by schematics ng g c product-list Generate a component ng g c <name> --inline-template Template in ts file? ng g c <name> --spec=false Without unit tests ng g c <name> --flat Should a folder be created
26. CLI: Serve and build 29.05.2018 Angular Developer Quick Start 30 ng serve Serve the app ng s -o Serve the app and open ng build Build in dev mode ng build --prod Build in prod mode
27. CLI: Other commands 29.05.2018 Angular Developer Quick Start 31 ng test Run unit tests ng test --code-coverage Create code coverage doc ng e2e Run end-to-end test ng doc <filter> Open angular.io API reference
28. CLI: Other commands (since Angular CLI 6) 29.05.2018 Angular Developer Quick Start 32 ng g application <name> Create a project in same ws ng g library Create a library ng add <package> Add package based on schematics ng update Update packages Or create own schematics
