+## 安装与使用
+
+#### **yarn**
+
+```bash
+yarn add @redux@^^5.0.1
+```
+
+#### **npm**
+```bash
+npm install @redux@^5.0.1
+```
+
+
+下面展示了这个库的基本使用场景:
+
+1.编写子reducer,负责state具体变化的过程
+
+```ts
+const defaultState = {
+ number: 100,
+}
+type State = {
+ counterState: {
+ number: number;
+ };
+};
+
+const counterReducer = (state = defaultState, action: { type: any; }) => {
+ switch (action.type) {
+ case 'ADD_NUMBER':
+ return {
+ ...state,
+ number: state.number + 1
+ };
+ default:
+ return state;
+ }
+}
+
+const rootReducer = combineReducers({// 这个对象就是应用State
+ // 应用State赋值
+ counterState: counterReducer,
+});
+```
+
+2.定义 Slice State 和 Action Types。每个 slice 文件都应该为其初始 state 值定义一个类型,以便 createSlice 能够推断每个案例 reducer 中的 state 类型。
+
+```ts
+const rootReducer = combineReducers({ counterState: counterReducerfun });
+const store = createStore(rootReducer);
+const addNumberAction = { type: 'ADD_NUMBER' };
+```
+
+3.在<App>
的外层放置一个<Provider>
,并将 store 作为 prop 传递
+```ts
+// 导出组件
+export default function TestPage() {
+ return (
+ // 将store作为props传递给组件,这样组件就能访问到store和dispatch方法了。
+
+
+
+
+ );
+}
+```
+
+4.在 React 组件中使用 Redux State 和 Actions
+```ts
+import React, { useState } from 'react';
+
+import { useSelector, useDispatch } from "react-redux";
+
+import { decrement, increment } from './counterSlice';
+
+export function Counter() {
+ // `state` arg 已经正确被键入 `RootState`
+ const number = useAppSelector((state:State) => state.counter.number);
+ const dispatch = useAppDispatch();
+
+ // 省略渲染逻辑
+}
+```

+
+ #### **createStore**
+| Name | Description | Type | Required | HarmonyOS Support |
+| ---- | ---- | ---- | -------- | -------- |
+| createStore() | Create a Redux store that contains the complete state tree of your program. The application should have a storage. | function | NO | yes |
+ #### **Store**
+| Name | Description | Type | Required | HarmonyOS Support |
+| ---- | ---- | ---- | -------- | -------- |
+| getState() | Returns the current state tree of the application. It is the same value returned by the last reducer of the store. | function | NO | yes |
+| dispatch(action) | This is the only way to trigger state changes | function | NO | yes |
+| subscribe(listener) | Add a change listener | function | NO | yes |
+| replaceReducer(nextReducer) | Replace the reducer currently used by the store to calculate state | function | NO | yes |
+ #### **combineReducers**
+| Name | Description | Type | Required | HarmonyOS Support |
+| ---- | ---- | ---- | -------- | -------- |
+| combineReducers() | The combineReducers auxiliary function is to combine an object with multiple different reducer functions as value into a final reducer function, and then call the createStore method on this reducer. | function | NO | yes |
+ #### **bindActionCreators**
+| Name | Description | Type | Required | HarmonyOS Support |
+| ---- | ---- | ---- | -------- | -------- |
+| combineReducers() | Convert an object whose value is a different action creator into an object with the same key. | function | NO | yes |
+ #### **compose**
+| Name | Description | Type | Required | HarmonyOS Support |
+| ---- | ---- | ---- | -------- | -------- |
+| compose() | Combine multiple functions from right to left. | function | NO | yes |
