最简单的React和Redux整合的例子

安装create-react-app

npm install -g create-react-app

创建项目

create-react-app reactreduxrouterdemo

cd reactreduxrouterdemo

安装第三方模块

npm install --save redux

npm install --save react-redux

npm install --save react-router

修改index.js

import React, { Component } from 'react';
import ReactDOM from 'react-dom';
import { createStore } from 'redux';
import { Provider, connect } from 'react-redux';

//定义组件
class App extends Component{
render() {
const {text, onChangeText, onButtonClick} = this.props;
return (
<div>
<h1 onClick={onChangeText}> {text} </h1>
<button onClick={onButtonClick}>click me</button>
</div>
);
}
}

//action
const changeTextAction = {
type:'CHANGE_TEXT'
}
const buttonClickAction = {
type:'BUTTON_CLICK'
}

//reducer
const initialState = {
text: 'Hello'
}
const reducer = (state = initialState, action) => {
switch (action.type) {
case 'CHANGE_TEXT':
return {
text: state.text=='Hello' ? 'world':'Hello'
}
case 'BUTTON_CLICK':
return {
text: 'Hello world'
}
default:
return initialState;
}
}

//store
let store = createStore(reducer);

//映射Redux state到组件的属性
function mapStateToProps(state) {
return { text: state.text }
}

//映射Redux actions到组件的属性
function mapDispatchToProps(dispatch){
return{
onButtonClick:()=>dispatch(buttonClickAction),
onChangeText:()=>dispatch(changeTextAction)
}
}

//连接组件
App = connect(mapStateToProps, mapDispatchToProps)(App)

//渲染组件
ReactDOM.render(
<Provider store={store}>
<App />
</Provider>,
document.getElementById('root')
)

这个例子大概是最简单的了， 而且每一步注释都非常清楚了。

运行工程npm start
