Redux

store

存儲(chǔ)state，唯一store。
創(chuàng)建store
createStore([reducer], [preloadedState], applyMiddleware([middlewares]))

Provider

reducer

唯一可直接修改state的方式，為function，傳入state,action，返回state一個(gè)新的對(duì)象。

combineReducers

組合多個(gè)reducer

官方示例

rootReducer = combineReducers({potato: potatoReducer, tomato: >tomatoReducer})
// This would produce the following state object
{
 potato: {
   // ... potatoes, and other state managed by the potatoReducer ...
 },
 tomato: {
   // ... tomatoes, and other state managed by the tomatoReducer, maybe >some nice sauce? ...
 }
}

action

帶有key為type的一個(gè)object，引入redux-thunk時(shí)可為function以處理異步邏輯。
通過(guò)dispatch([action])的方式，發(fā)起一個(gè)動(dòng)作 => 中間件處理邏輯之后 => 調(diào)起reducer執(zhí)行對(duì)應(yīng)type的代碼，返回新的state。

dispatch

發(fā)起一個(gè)動(dòng)作，傳入action，該方法由store提供。
store.dispatch
