Webpack不自动编译对React文件中代码的更改

Question

我最近开始尝试将React与Webpack一起使用，以便在更改某些内容时自动编译更改。然而，尽管我用Google搜索内容，但我似乎无法找到为什么它不起作用。

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") 
); 

的package.json

{ 
    "name": "static", 
    "version": "1.0.0", 
    "description": "", 
    "main": "app.js", 
    "dependencies": { 
    "babel-preset-es2015": "^6.3.13", 
    "babel-preset-react": "^6.3.13", 
    "history": "^1.13.1", 
    "react-router": "^1.0.2" 
    }, 
    "devDependencies": { 
    "babel-core": "^6.3.17", 
    "babel-loader": "^6.2.0", 
    "webpack": "^1.12.9", 
    "webpack-dev-server": "^1.14.0" 
    }, 
    "scripts": { 
    "dev": "webpack-dev-server --inline --hot --progress --colors --port 8090", 
    "test": "echo \"Error: no test specified\" && exit 1" 
    }, 
    "author": "", 
    "license": "ISC", 
    "private": true 
} 

webpack.config.js

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 
};

，你必须使用01如果你想例如，你可以使用反应路由器例如React-router

我用我的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') 
    }] 
    } 
};
