# API 文档 Redux 的 API 非常少。Redux 定义了一系列的约定（contract）来让你来实现（例如 [reducers](../Glossary.md#reducer)），同时提供少量辅助函数来把这些约定整合到一起。 这一章会介绍所有的 Redux API。记住，Redux 只关心如何管理 state。在实际的项目中，你还需要使用 UI 绑定库如 [react-redux](https://github.com/gaearon/react-redux)。 ### 顶级暴露的方法 - [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 上面介绍的所有函数都是顶级暴露的方法。都可以这样引入： #### ES6 ```js import { createStore } from 'redux' ``` #### ES5 (CommonJS) ```js var createStore = require('redux').createStore ``` #### ES5 (UMD build) ```js var createStore = Redux.createStore ```
