热模块替换启用，但不能正常工作http：// localhost：3000/__ webpack_hmr

Question

我的问题是，无论我做什么，我都会在wepack_hmr上得到一个404，我不能为我的生活找出原因可用。

完整的WebPack配置

var url = 'http://localhost:3000'; 

module.exports = { 

    resolve: { 
     extensions: ['', '.js'] 
    }, 

    entry: ['webpack-hot-middleware/client','./src/client/js/Kindred'], 

    devtool: 'cheap-module-source-map', 

    module: { 
     loaders:[ 
      { 
       test: /\.js$/, 
       exclude: /node_modules/, 
       loader: 'babel', 
       query: {presets: ['es2015', 'react', 'react-hmre', 'stage-0']} 
      }, 
      {test: /\.png$/, loader: "url-loader?limit=100000"}, 
      // Images 
      {test: /\.jpg$/, loader: "file-loader"}, 
      { 
       test: /\.(eot|svg|ttf|woff|woff2)$/, 
       loader: 'file?name=./font/[name].[ext]' 
      }, 
      // Stylesheets 
      { test: /\.scss$/, loader: ExtractTextPlugin.extract('style', 
       [ 
        'css?sourceMap&modules&importLoaders=1', 
        'sass?sourceMap&modules', 
       ] 
      ) }, 
      // Font Definitions 
      { test: /\.svg$/, loader: 'url?limit=65000&mimetype=image/svg+xml&name=public/font/[name].[ext]' }, 
      { test: /\.woff$/, loader: 'url?limit=65000&mimetype=application/font-woff&name=public/font/[name].[ext]' }, 
      { test: /\.woff2$/, loader: 'url?limit=65000&mimetype=application/font-woff2&name=public/font/[name].[ext]' }, 
      { test: /\.[ot]tf$/, loader: 'url?limit=65000&mimetype=application/octet-stream&name=public/font/[name].[ext]' }, 
      { test: /\.eot$/, loader: 'url?limit=65000&mimetype=application/vnd.ms-fontobject&name=public/font/[name].[ext]' } 
     ] 
    }, 

    sassLoader: { 
     includePaths: [ 'src/client/scss' ] 
    }, 

    plugins: process.env.NODE_ENV === 'production' ? [ 
     new ExtractTextPlugin ('app.css', {allChunks: true}), 
     new webpack.optimize.DedupePlugin(), 
     new webpack.optimize.OccurrenceOrderPlugin(), 
     new webpack.optimize.UglifyJsPlugin() 
    ] : [ 
     new webpack.HotModuleReplacementPlugin(), 
     new webpack.NoErrorsPlugin(), 
     new ExtractTextPlugin("style.css") 
    ], 

    devServer: { 
     hot: true, 
     contentBase: './public' 
    }, 

    output: { 
     path: path.join(__dirname), 
     publicPath: '/', 
     filename: 'bundle.js' 
    } 

}; 

节点CMD运行

webpack-dev-server --inline --history-api-fallback --port 3000 

当加载了页面

[HMR] Waiting for update signal from WDS...

我花了它的运行，但它不是：/

Answer 1

好只是所以它很容易让人们看到我做了什么得到它在这里工作是：

我认为这是我更容易彻底清除SCSS并开箱即用的CSS模块。这似乎有很大帮助。

我用git@github.com：christianalfoni/webpack-express-boilerplate.git来帮助我指导自己。知道我有一个工作的东西，实际上教会了我比在webpack之前学到的更多的东西。正如你可以猜到这不是很多：D

另一个主要的变化，真正帮助改变路径并不令人意外。但这些都是相对于output.path之前的路径性别而言的，但我认为这是相对于wepack.config.js而言的，并不是说从那里开始，所有内容都将被视为文档根目录，即使对于html和css也是如此。

**关键部分:) **

我也有更新我的快递成立，因为我没有给它一个express.static路径...哦，我的愚蠢，我怎么会错过这样一个基本事情..所以：

快速

app.use(express.static(__dirname + '/public/')); //Don't forget me :(

决赛CSS

/* Webfont: Lato-Black */@font-face { 
    font-family: 'LatoBlack'; 
    src: url('/font/Lato-Black.eot'); /* IE9 Compat Modes */ 
    src: url('/font/Lato-Black.eot?#iefix') format('embedded-opentype'), /* IE6-IE8 */ 
     url('/font/Lato-Black.woff2') format('woff2'), /* Modern Browsers */ 
     url('/font/Lato-Black.woff') format('woff'), /* Modern Browsers */ 
     url('/font/Lato-Black.ttf') format('truetype'); 
    font-style: normal; 
    font-weight: normal; 
    text-rendering: optimizeLegibility; 
}

其实我已经贴了同样的回答两次。但他们都有关系。可悲的是:(
