- 28. Hello world with VueJS
- 29. My favorite and not-so-favorite features
- 30. Your Favorite Angular Features?
- 31. My Favorite Angular Features Dependency Injection Angular CLI Resembles Java MVC Frameworks Two-way Binding Components, Services, and Directives TypeScript Ionic Framework Webpack compiling TypeScript Searchability: Angular vs AngularJS Release Candidates in 2016 Testing Infrastructure Too much boilerplate code
- 32. Your Favorite React Features?
- 33. My Favorite React Features One way binding Virtual DOM JSX Flexibility Component based composability Smart & Dumb components React Native One way binding Dependency fatigue JSX Too many options for state management No official style guide
- 34. Your Favorite VueJS Features?
- 35. My Favorite VueJS Features Two way binding Virtual DOM JSX is supported Flexibility Component based composability Low learning curve Smaller community No official style guide Some library documentation are only in chinese
- 36. Framework vs Library Angular = Full fledged MVVM framework React/VueJS = View rendering library Angular = React + Redux + React Router … (React & Friends)
- 37. Let’s get the similarities out of the way All are component-based All are client side MVVM frameworks for building SPAs All supports server-side rendering All of them supports native mobile app development All of them requires a build tool like webpack for optimal usage All of them have comparable performance All of them are MIT licenced (Finally!) All of them support Typescript and provides official type definitions
- 38. Kickstarting Angular and React
- 42. Angular CLI vs Create React App Minimal dependencies ES6 by default Yarn by default 325 Lines of code (not counting README) PWA Score: 55/82 ng new app-name --minimal TypeScript by default npm by default 225 Lines of code PWA Score: 18/36 (dev/prod) ng generate component | service
- 43. An optimal stack for Java developers
- 44. Easy to start Flexible Typescript React Redux React router Jest Typescript Angular Karma Mocha Chai
- 45. Using JHipster to kickstart
- 46. Want to learn more about JHipster? Come to our BOF tonight!
- 47. Demo Time!
- 48. Recommendations
- 49. Learn the Language well, Frameworks are just tools to help
- 50. Recommendation If you have a lot of state: React If you need simplicity & clean code: VueJS If you’re familiar with Java MVC frameworks: Angular If you want the easiest to learn and lightweight framework: VueJS If you work at Facebook: React If you work at Google: Angular If you like structure and a helping hand: Angular If you like flexibility: React or VueJS
