Echte Cross-Plattform Anwendungen mit Angular, Cordova & Electron

Der Traum von einer einzigen Codebasis für alle Clientplattformen: Er lebt immer noch. In dieser Session zeigt Ihnen Christian Weyer, wie weit dieser Traum mit HTML5/JavaScript und aktuellen Cross-Plattform-Werkzeugen Wirklichkeit werden kann. Auf Basis moderner UI/UXKonzepte lassen sich Oberflächen für Desktops, Tablets und Smartphones entwerfen – mit einer Codebasis. Mischt man diesen Ansatz mit
Tools wie Cordova und Electron, so kann man mit Single-Page-Applications-(SPA-)Frameworks wie Angular 2 echte Anwendungen für alle relevanten Plattformen und Devicegrößen bauen, Mobile und Desktop: Windows, Linux, macOS, iOS, Android und Co. – und natürlich den Browser. Sehen Sie all dies in Action!

12. 12 The web as a platform mit Angular, Cordova & Electron Echte Cross-Plattform Anwendungen
13. 13 § Web browser & HTML5 as a powerful platform § JavaScript & TypeScript as application programming languages § Angular as smart client application framework – or React, or… § Flexible layouts with CSS3 & flexbox Real applications Echte Cross-Plattform Anwendungen mit Angular, Cordova & Electron
14. 14 § Smart clients with single page applications (SPA) § Open source, bets heavily on TypeScript § Features § Consequently component-based § Metadata-driven § Focus on proven patterns and separation of concerns § Components, views, view models § Services and dependency injection § Large tooling ecosystem and platform tools available § Angular CLI § IDEs like WebStorm, Visual Studio Code Component-based applications with Angular mit Angular, Cordova & Electron Echte Cross-Plattform Anwendungen
15. 15 Web & native environments mit Angular, Cordova & Electron Echte Cross-Plattform Anwendungen
16. 16 § Toolkit and framework for building native application shells for our web apps § Make ‘app apps’ from ‘web apps’ J § Uses native web view components to host the original web app locally § Provides framework and APIs via plugins to interact with underlying native platforms § CLI tools for automating project creation & build § We always need the native SDKs (e.g. iOS, Android, Windows) Mobile apps with Cordova JS HTML CSS Native wrapper Deploy to devices mit Angular, Cordova & Electron Echte Cross-Plattform Anwendungen
17. 17 Cordova architecture Mobile OS iOS Android Windows 10 UWP many more Cordova Application Cordova Plugins Geolocation Notifications Contacts Media Camera Custom Plugins HTML Rendering Engine (WebView) Single Page App HTML JS CSS Assets config.xml HTML APIs Cordova APIs OS APIs OS APIs Cordova Native APIs mit Angular, Cordova & Electron Echte Cross-Plattform Anwendungen
