Angular vs React Smackdown - Devoxx BE 2017

This talk discusses the pros and cons of Angular and React and shows how they're similar, as well as how they're different. Deepu defends React, Matt defends Angular. We'll even show you the same app created with React and Angular via JHipster.

Example projects are on GitHub:

Angular: https://github.com/hipster-labs/devoxx17-jh-angular
React: https://github.com/hipster-labs/devoxx17-jh-react

And they're deployed to Heroku:

9. The History of Angular Started as AngularJS in 2009 by Miško Hevery GWT == 3 developers, 6 months AngularJS == 1 developer, 3 weeks Announced Angular 2, September 2014 2.0 Released in September 2016 5.0 Released November 1, 2017 #Devoxx @deepu105 | @mraible #Devoxx17

14. The History of React React was created by Jordan Walke in 2011 & Open sourced in May 2013 Inspired by XHP, an HTML components framework for PHP Within one year, had large sites Khan Academy, New York Times, Airbnb + Facebook and Instagram 16.0 released on September 26, 2017 #Devoxx @deepu105 | @mraible #Devoxx17

19. Getting Started Comparison #Devoxx @deepu105 | @mraible #Devoxx17
20. 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 #Devoxx @deepu105 | @mraible #Devoxx17
21. Your Favorite Angular Features? #Devoxx @deepu105 | @mraible #Devoxx17
22. Matt’s 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 #Devoxx @deepu105 | @mraible #Devoxx17
23. Your Favorite React Features? #Devoxx @deepu105 | @mraible #Devoxx17
24. Deepu’s 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 #Devoxx @deepu105 | @mraible #Devoxx17

27. Framework vs Library Angular = Full fledged MVVM framework React = View rendering library Angular = React + Redux + React Router … (React & Friends) #Devoxx @deepu105 | @mraible #Devoxx17
28. #Devoxx @deepu105 | @mraible #Devoxx17
29. Let’s get the similarities out of the way Both Angular and React are component-based Both are client side MVVM frameworks for building SPAs Both support server-side rendering Both supports native mobile app development Both requires a build tool like webpack for optimal usage Both have comparable performance Both are backed by big companies (Google & Facebook) Both are MIT licenced (Finally!) #Devoxx @deepu105 | @mraible #Devoxx17
30. It’s Time to Vote! #Devoxx @deepu105 | @mraible #Devoxx17
31. Technical Differences? #Devoxx @deepu105 | @mraible #Devoxx17
32. Follows EL in HTML approach Uses regular DOM Typescript based (Possible to write in plain JS but not recommended) Supports dependency injection Supports Lazy loading & AOT State management by default supports one way and 2 way binding Technical Differences Follows HTML in JS (JSX) approach Uses Virtual DOM ES6 + JSX based (Possible to use Typescript + TSX as well) Does not have the concept Lazy loading is possible, No AOT State management is only one way binding and libraries like Redux or MobX is used more often for state management #Devoxx @deepu105 | @mraible #Devoxx17
33. Philosophical Differences? #Devoxx @deepu105 | @mraible #Devoxx17
34. An opinionated framework Promotes object-oriented approach Offers everything required to build an SPA Differing Philosophies A view rendering library Promotes functional approach Requires use of a many 3rd party libraries like Redux, React router etc. #Devoxx @deepu105 | @mraible #Devoxx17
35. Usability? #Devoxx @deepu105 | @mraible #Devoxx17
36. Less flexible Often results in more code for same task compared to React Usability Very flexible Often results in less code for same task compared to Angular #Devoxx @deepu105 | @mraible #Devoxx17
37. Which one is easier to learn? #Devoxx @deepu105 | @mraible #Devoxx17
38. Learning Angular is a framework with lot of concepts and hence is complex to learn causing JS fatigue Opinionated and provides guidance for most use cases React itself is easier to learn but since it is only a view renderer it would require many other libraries for state management, routing etc ending up in same fatigue Limited guidance. Requires one to choose a stack and decide on 3rd party libraries and approaches to follow #Devoxx @deepu105 | @mraible #Devoxx17
39. Which one has a better ecosystem? #Devoxx @deepu105 | @mraible #Devoxx17
40. Ecosystem Ecosystem is not that huge Easier to set up for a full fledged application out of the box Limited choice when it comes to alternative approaches for example state management Huge ecosystem Difficult to set up for a full fledged application due to above point Lot of choices in approaches #Devoxx @deepu105 | @mraible #Devoxx17
