Redux
Redux
(
http://redux.js.org
)
已经毋庸置疑地成为了众多
Flux
或类
Flux
库中的翘楚之
一。
Redux
是基于
Flux
的,旨在处理应用程序中数据流变化的问题。
Redux
是由
Dan
Abramov
(

Flux
。它包含
Action
、
Action
生
成器、
Store
,以及用于修改
State
的
Action
对象。
Redux
通过移除
Dispatcher,
对
Flux
的概念进行了一些简化,并使用单个不可变对象表
示应用程序的
State
。
Redux
还引入了
Reducer
,它并不是
Flux

Reducer
是纯函数,它会根据当前的
State
和
Action
返回一个新的
