Javascript 网页包未自动编译对React文件中代码的更改

我最近开始尝试使用React和Webpack，在某些内容发生更改时自动编译更改。然而，尽管我在谷歌上搜索到了心满意足的内容，但我似乎无法找到它为什么不起作用

app.js

import React from 'react'
import ReactDOM from 'react-dom'
import {Router, Route, Link} from 'react-router'
import ProductList from './products'

class Main extends React.Component {
    constructor(props){
        let products = [];

        super(props);

        this.state = {
            name: "Harry"
        };
    }
    render(){
        return(
            <Storefront name={this.state.name} />
        );
    }
}

var a = 10;

let Storefront = (props) =>
<div className="container">
    <h4>Welcome to the React Store Front, {props.name}!</h4>
    <Link to="/products">View Products</Link>
</div>;

ReactDOM.render(
    <Router>
        <Route path="/" component={Main}/>
        <Route path="/products" component={ProductList}/>
    </Router>,
    document.getElementById("app")
);

module.exports = {
    context: __dirname,
    entry: ['webpack/hot/dev-server', './app.js'],
    output: {
        filename: "app.js",
        path: __dirname + "/dist"
    },
    module: {
        loaders: [
            {
                test: /\.js$/,
                exclude: /node_modules/,
                loaders: ["babel-loader?presets[]=react,presets[]=es2015"]
            },
            {
                test: /\.jsx$/,
                loaders: ['babel-loader?presets[]=react,presets[]=es2015']
            }
        ]
    },
    resolve: {
        extensions: ['', '.js', '.jsx']
    },
    watch: true
};

webpack.config.js

import React from 'react'
import ReactDOM from 'react-dom'
import {Router, Route, Link} from 'react-router'
import ProductList from './products'

class Main extends React.Component {
    constructor(props){
        let products = [];

        super(props);

        this.state = {
            name: "Harry"
        };
    }
    render(){
        return(
            <Storefront name={this.state.name} />
        );
    }
}

var a = 10;

let Storefront = (props) =>
<div className="container">
    <h4>Welcome to the React Store Front, {props.name}!</h4>
    <Link to="/products">View Products</Link>
</div>;

ReactDOM.render(
    <Router>
        <Route path="/" component={Main}/>
        <Route path="/products" component={ProductList}/>
    </Router>,
    document.getElementById("app")
);

module.exports = {
    context: __dirname,
    entry: ['webpack/hot/dev-server', './app.js'],
    output: {
        filename: "app.js",
        path: __dirname + "/dist"
    },
    module: {
        loaders: [
            {
                test: /\.js$/,
                exclude: /node_modules/,
                loaders: ["babel-loader?presets[]=react,presets[]=es2015"]
            },
            {
                test: /\.jsx$/,
                loaders: ['babel-loader?presets[]=react,presets[]=es2015']
            }
        ]
    },
    resolve: {
        extensions: ['', '.js', '.jsx']
    },
    watch: true
};

您必须使用

webpack热中间件

NPM链接

若你们想举例说明，那个么你们可以使用react路由器举例说明

我已使用和我的webpack.config文件

/* eslint-disable no-var */
var path = require('path');
var webpack = require('webpack');

module.exports = {
  entry: [
    'webpack-hot-middleware/client',
    './scripts/index'
  ],
  devtool: 'eval-source-map',
  output: {
    path: __dirname,
    filename: 'bundle.js',
    publicPath: '/static/'
  },
  plugins: [
    new webpack.HotModuleReplacementPlugin(),
    new webpack.NoErrorsPlugin()
  ],
  module: {
    loaders: [{
      test: /\.js$/,
      loaders: ['babel'],
      include: path.join(__dirname, 'scripts')
    }]
  }
};

谢谢你的回答。我试着按照npm页面上的步骤进行操作，但当它说“将其添加到服务器”时，我不知道该怎么做。我正在使用LocalHost，谢谢你的回答。我试着按照npm页面上的步骤进行操作，但当它说“将其添加到服务器”时，我不知道该怎么做。我正在使用localhost
