KKbOX Introduction • 2015/1/28 ~ 1/29 @Facebook HQ, CA •
160~ • 18 sessions + 2 panels • Tickets sold out in 1 minutes (3 waves)
KKbOX Highlight
KKbOX Highlight • Performance • Flux & Relay • Component
Communication • React Native
KKbOX Performance
KKbOX The Keys to React Performance • How to render
• When to render
KKbOX Solutions • Virtual DOM • Optimistic re-rendering
KKbOX Optimistic re-rendering • Pure Component (prop, state) • Immutable
data • shouldComponentUpdate • Only re-render when value is changed • PureRenderMixin
KKbOX Why Immutable? • Immutable data is no side effect!
• Shared mutable state is the root of all evil - Pete Hunt
KKbOX
KKbOX Why Immutable? (cont.) • The reason why Om is
faster than React • Data or Value is immutable in Clojure • Immutable + PureRenderMixin
KKbOX facebook.github.io/immutable-js
KKbOX Immutable.js • It Implements immutable data structure in JavaScript
• Use the same algorithm with Clojure
KKbOX PureRenderMixin implementation Simple but efficient
KKbOX Flux & Relay
KKbOX Flux & Relay • Flux is an architecture •
Relay is designed for solving data fetching problem
KKbOX Flux • Unidirectional data flow • Easy to debug
• It’s more of a pattern rather than a formal framework
KKbOX Flux
KKbOX Relay • Relay is designed for solving data fetching
problem • Efficient • Cache • GraphQL
KKbOX Relay Architecture
KKbOX RelayContainer & Relay Store
KKbOX Props coupling
KKbOX
KKbOX Only modify 1 component
KKbOX
KKbOX Component Communication
KKbOX Component Communication • It is a general problem •
Two scenarios • Parent & Child • No relationship
KKbOX Parent & Child • Pass props • Use Callbacks
KKbOX No Relationship • Global event system • Flux •
Codecademy • Adapter (broadcast) • Channel (JS-CSP)
KKbOX Adaptor
KKbOX React Native
KKbOX When ?
KKbOX The reason to go native
KKbOX React Native • No WebView, it uses JavaScript to
control native UI. • JavaScriptCore • 3 pillars • Touch Handling • Native Components • Style & Layout • Reimplement Flex Box.
KKbOX Benefits
KKbOX Access to Platform Components Different platforms have their own
behaviours and styles
KKbOX Instant UI change
KKbOX Show errors on your face
KKbOX Hard to figure out
KKbOX Get benefits from existing solution
KKbOX ComponentKit
KKbOX Declarative
KKbOX Same idea
KKbOX The same concept ideally…
KKbOX facebook Ads Manager React Native + Flux + Relay
KKbOX facebook Groups React Native + Native Objective-C
KKbOX native.reactjs.com
KKbOX nuclide.io Implement on top of Atom
KKbOX Conclusion
KKbOX Conclusion • Learn once, write anywhere • React makes
reusable components possible • Look forward to Flux & Relay + GraphQL • Tooling • nuclide • Jest
KKbOX Conclusion (cont.) • React Native is amazing but you
still need to learn how native (Android/iOS) works • Embrace Immutable data structure to reduce complexity • It is time to use ES6 & ES2015 • Functional Programming is hot • immutable data structure & functions composition • #clojure
KKbOX Trending • React-inspired View - ComponentKit • Flux architecture
in Server side or App • Functional Programming
KKbOX Functional Programming • Operates on streaming and abstracts your
behaviours • Clojure • LISP • Immutable data structure • ClojureScript • #clojure
