Cycle.jsのLT NDSiN#12×Niigata.js×C4N May 20, 2017 @chooblarin
自己紹介 • @chooblarin • 畠山 創太(はたけやま そうた) • Android/iOSのアプリ開発 •
今年の1月に新潟ʹ6λʔϯ͠·ͨ͠
CycleConfが先月に開催
今日はCycle.js についてLTします
Disclaimer • 私はフロントエンドのエンジニアではありません • 雰囲気でJavaScriptを書いています • JavaScript最高⤴⤴
Cycle.js
Cycle.js is a JS framework created by @staltz
I am a Fun of him “The introduction to Reactive
Programming you’ve been missing”
I am a Fun of him RxMarbles
昨今のプログラミング • 状態(ステート)の管理は難しい • 非同期のプログラミングは難しい • 色々頑張っても結局これらは難しい
“André Staltz - Some problems with React/Redux”
“the frontend co!"unity is to continue searching for better solutions.”
“first with jQuery et al, then Backbone, then Angular, and now React. Let’s not stop there.”
Cycle.jsの コンセプト
アプリ is 関数: (外界) => (外界)
main関数を分割する指針
MVIアーキテクチャ
MVI • Intent: (UserEvents) => (Action) • Model: (Action) =>
(State) • View: (State) => (Rendering) ※これら全てはただの関数にすぎない
main関数はComponent
そのmain関数は別のmain関数のComponent
