Mobile Development with Ionic, React Native, and JHipster - Frontend Tech 2020

Mobile development offers a lot of options. To develop native apps, you can use Java or Kotlin on Android. On iOS, you can use Objective C or Swift. There are other options, too. You can build hybrid mobile apps and Progressive Web Apps (PWAs). Hybrid mobile apps are those created with web technologies (HTML, JavaScript, and CSS) that look like native apps. PWAs have the ability to work offline and act like mobile apps.

In this talk, you'll learn more about a few different mobile technologies: Ionic (with Angular), React Native, and PWAs. You'll walk away with knowledge of how to build mobile + Spring Boot apps in minutes with JHipster.

13. Agenda 1. Introduction to JHipster 2. Ionic for JHipster 3. JHipster Ignite 4. JHipster Roadmap 5. Action!
14. Introduction to JHipster What is JHipster? Installing and Using JHipster JHipster Microservices and OIDC Progressive Web Applications Overview Part 1
15. What is JHipster? + =
16. What is JHipster? JHipster is a development platform to generate, develop and deploy Spring Boot + Angular/React Web applications and Spring microservices. and Vue! ✨ www.jhipster.tech
17. A powerful workflow to build your application with Yeoman, Webpack, and Maven/Gradle JHipster Goals A sleek, modern, mobile-first front- end with Angular and Bootstrap A high-performance and robust Java stack on the server side with Spring Boot A robust microservice architecture with JHipster Registry, Netflix OSS, Elastic Stack, and Docker
18. How to Use JHipster Install JHipster and Yeoman, using npm: npm install -g generator-jhipster Create a directory and cd into it: mkdir newapp && cd newapp Run it! jhipster
19. Microservices with JHipster
20. Monolith Examples JHipster 6 Demo github.com/mraible/jhipster6-demo youtu.be/uQqlO3IGpTU 21-Points Health github.com/mraible/21-points infoq.com/minibooks/jhipster-mini-book
21. Progressive Web Apps Originate from a secure origin, load while offline, and reference a web app manifest.
22. Progressive Web Apps Can be installed on your mobile device, look and act like a native application, but are distributed through the web.
23. Progressive Web Apps Are fast!
24. Enable PWA in JHipster <script> if ('serviceWorker' in navigator) { window.addEventListener('load', function() { navigator.serviceWorker.register('/service-worker.js') .then(function () { console.log('Service Worker Registered'); }); }); } </script> src/main/webapp/index.html
25. Demo Using JHipster, create an app Generate entities in app Convert app to be a PWA Test with Lighthouse
26. JHipster Test Coverage
27. JHipster 6.8.0 Lighthouse Report
28. Part 2 Ionic for JHipster What is Ionic? Why? Ionic Module for JHipster JWT and OIDC Support Entity Generator
29. Ionic Ionic Framework Develop Hybrid & PWA Apps https://ionicframework.com Stencil Vanilla Web Components https://stenciljs.com PWA Toolkit Lightning fast PWAs https://github.com/ionic- team/ionic-pwa-toolkit
30. Why? The first version of 21-Points Health I wrote with JHipster 2.x was painful to use on a mobile device. Versions 4.x and 5.x are better, but still not great. I want to develop the best user experience. Native apps are painful to distribute, but work better than PWAs (on iOS).
31. Run it! yo jhipster-ionic Ionic Module for JHipster Because Ionic Apps need some JHipster too! https://github.com/oktadeveloper/generator-jhipster-ionic Install Ionic and the Ionic Module for JHipster, using npm: npm i -g @ionic/cli generator-jhipster-ionic yo Profit!
32. Demo Create an app with Ionic4J Generate entities in app Modify UI to be friendlier Run on iOS
33. Use Ionic for JHipster to Create Mobile Apps developer.okta.com/blog/2019/06/24/ionic-4-angular-spring-boot-jhipster
34. Part 3 Ignite JHipster What is React Native? What is Ignite CLI? Ignite JHipster JWT and OIDC Support Entity Generator
35. Works on macOS, Windows, and Linux Ignite CLI Saves an average of two weeks Easily spin up a new React Native app An ever-expanding list of boilerplates and plugins infinite.red/ignite
36. Create an app: ignite new myapp -b ignite-jhipster Ignite JHipster https://github.com/ruddell/ignite-jhipster Install Ignite CLI and Ignite JHipster, using npm: npm i -g ignite-cli ignite-jhipster Ignite! A React Native boilerplate for JHipster apps
