1. 组件状态的集中管理库,用法类似于`redux`
2. 创建reducers
   ```javascript
    const initState = {
        type: 'receive',
        date: dateFormat("yyyy-MM-dd", new Date())
    }
    export const searchRecucer = (action,preState = initState) => {
        let {type, data} = action;
        switch (type) {
            case 'GOSEARCH':
                return data;
            default:
                return preState;
        }
    }
    const initTest={
        a:1,b:2
    }
    export const testReducer=(action,preState=initTest)=>{
        let {type, data} = action;
        switch (type) {
            case 'GOTEST':
                return data;
            default:
                return preState;
        }
    }
        
   ```
3. 创建actions
   ```javascript
   export const search = (data) => {
       return {type: "GOSEARCH", data}
   }
   
   const change = (data) => {
       return {type: "GOTEST", data};
   }
   // 异步action
   export const changeTest = (data) => {
       return  (dispatch,preState)=> {
           setTimeout(() => {
                dispatch(search(data));
           }, 2000);
       }
   }
   ```
4. 创建store
   ```javascript
   import {createStore,combineReducers} from "yushidux";
   
   import {searchRecucer,testReducer} from "./reducers";
   const reducers={
       search:searchRecucer,
       test:testReducer
   };
   export default createStore(combineReducers(reducers))
   ```
5. 在修改store数据
   ```javascript
       import store from "../../store";
       import {search} from "../../store/actions";
   	// 
   		store.dispatch(search(data))
   ```
6. 在组件中订阅数据变化
   ```javascript
       store.subscribe(()=>{
   		// dosomething
   	})
   ```
