Mobile App Development with Ionic, React Native, and JHipster - Connect.Tech 2021

Mobile App Development with Ionic, React Native, and JHipster - Connect.Tech 2021

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, we'll explore a few different mobile technologies: PWAs, React Native, and Ionic (with Angular). You'll walk away with knowledge of how to build mobile + Spring Boot apps in minutes with JHipster.

  12. Agenda 1. Comparing Mobile Frameworks 2. Introduction to JHipster 3.

    Mobile Framework Options - Ionic, React Native, and Flutter 4. Demos 5. Action!
  13. Comparing Mobile Frameworks Progressive Web Apps Hybrid Apps Native Apps

    Part 1
  14. Progressive Web Apps Originate from a secure origin, load while

    offline, and reference a web app manifest.
  15. Progressive Web Apps Can be installed on your mobile device,

    look and act like a native application, but are distributed through the web.
  16. Progressive Web Apps Are fast!

  17. Enabling a 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

  26. Introduction to JHipster What is JHipster? Installing and Using JHipster

    Authentication with OpenID Connect Code Quality Part 2
  27. A resilient microservice architecture with cloud native principles in mind

    JHipster Goals A sleek, modern, mobile-first UI with Angular, React, or Vue + Bootstrap for CSS A high-performance and robust server-side stack with excellent test coverage A powerful workflow to build your application with Webpack and Maven or Gradle
  28. How to Use JHipster Install JHipster and Yeoman, using npm:

    npm install -g generator-jhipster Create a directory and cd into it: take newapp Run it! jhipster

  36. Part 3 Ionic What is Ionic? Why? Ionic Module for

    JHipster JWT and OIDC Support Entity Generator
  37. 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
  38. 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).
  39. How is a mobile app for JHipster different from its

    Angular UI?
  40. Run it! yo jhipster-ionic Ionic Module for JHipster Because Ionic
