# API 文檔 Redux 的 API 非常少。Redux 定義了一系列的約定（contract）來讓你來實現（例如 [reducers](../Glossary.md#reducer)），同時提供少量輔助函數來把這些約定整合到一起。 這一章會介紹所有的 Redux API。記住，Redux 只關心如何管理 state。在實際的項目中，你還需要使用 UI 綁定庫如 [react-redux](https://github.com/gaearon/react-redux)。 ### 頂級暴露的方法 - [createStore(reducer, [preloadedState], [enhancer])](createStore.md) - [combineReducers(reducers)](combineReducers.md) - [applyMiddleware(...middlewares)](applyMiddleware.md) - [bindActionCreators(actionCreators, dispatch)](bindActionCreators.md) - [compose(...functions)](compose.md) ### Store API - [Store](Store.md) - [getState()](Store.md#getState) - [dispatch(action)](Store.md#dispatch) - [subscribe(listener)](Store.md#subscribe) - [getReducer()](Store.md#getReducer) - [replaceReducer(nextReducer)](Store.md#replaceReducer) ### 引入 上面介紹的所有函數都是頂級暴露的方法。都可以這樣引入： #### ES6 ```js import { createStore } from 'redux' ``` #### ES5 (CommonJS) ```js var createStore = require('redux').createStore ``` #### ES5 (UMD build) ```js var createStore = Redux.createStore ```
