当使用多个选项卡/浏览器时，webpack 热中间件更新所有选项卡实例

Question

我遇到了 webpack-hot-middleware 的问题，当我打开多个浏览器或选项卡实例（chrome 和 FF）时，我会在每个视觉操作中刷新或更新所有这些实例被触发。
例如，在 1 个选项卡上滚动会触发另一个选项卡上的滚动。
有人遇到过这种行为吗？这是我的 webpack 配置：

import webpack from 'webpack';
import HtmlWebpackPlugin from 'html-webpack-plugin';
import autoprefixer from 'autoprefixer';
import path from 'path';

export default {
  resolve: {
    extensions: ['*', '.js', '.jsx', '.json']
  },
  devtool: 'eval-source-map', // more info:https://webpack.github.io/docs/build-performance.html#sourcemaps and https://webpack.github.io/docs/configuration.html#devtool
  entry: [
    // must be first entry to properly set public path
    './src/webpack-public-path',
    'webpack-hot-middleware/client?reload=true',
    path.resolve(__dirname, 'src/index.js') // Defining path seems necessary for this to work consistently on Windows machines.
  ],
  target: 'web', // necessary per https://webpack.github.io/docs/testing.html#compile-and-test
  output: {
    path: path.resolve(__dirname, 'dist'), // Note: Physical files are only output by the production build task `npm run build`.
    publicPath: '/',
    filename: 'bundle.js'
  },

  plugins: [
    new webpack.DefinePlugin({
      'process.env.NODE_ENV': JSON.stringify('development'), // Tells React to build in either dev or prod modes. https://facebook.github.io/react/downloads.html (See bottom)
      __DEV__: true
    }),
    new webpack.HotModuleReplacementPlugin(),
    new webpack.NoEmitOnErrorsPlugin(),
    new HtmlWebpackPlugin({     // Create HTML file that includes references to bundled CSS and JS.
      template: 'src/index.html',
      minify: {
        removeComments: true,
        collapseWhitespace: true
      },
      inject: true
    }),
    new webpack.LoaderOptionsPlugin({
      minimize: false,
      debug: true,
      noInfo: true, // set to false to see a list of every file being bundled.
      options: {
        sassLoader: {
          includePaths: [path.resolve(__dirname, 'src', 'scss')]
        },
        context: '/',
        postcss: () => [autoprefixer],
      }
    })
  ],
  module: {
    rules: [
      {test: /\.jsx?$/, exclude: /node_modules/, loaders: ['babel-loader']},
      {test: /\.eot(\?v=\d+.\d+.\d+)?$/, loader: 'file-loader'},
      {test: /\.woff(2)?(\?v=[0-9]\.[0-9]\.[0-9])?$/, loader: 'url-loader?limit=10000&mimetype=application/font-woff'},
      {test: /\.[ot]tf(\?v=\d+.\d+.\d+)?$/, loader: 'url-loader?limit=10000&mimetype=application/octet-stream'},
      {test: /\.svg(\?v=\d+\.\d+\.\d+)?$/, loader: 'url-loader?limit=10000&mimetype=image/svg+xml'},
      {test: /\.(jpe?g|png|gif)$/i, loader: 'file-loader?name=[name].[ext]'},
      {test: /\.ico$/, loader: 'file-loader?name=[name].[ext]'},
      {test: /(\.css|\.scss|\.sass)$/, loaders: ['style-loader', 'css-loader?sourceMap', 'postcss-loader', 'sass-loader?sourceMap']}
    ]
  }
};

除了通过 webconfig 当然，我没有插件的特殊配置：

// This file configures the development web server
// which supports hot reloading and synchronized testing.

// Require Browsersync along with webpack and middleware for it
import browserSync from 'browser-sync';
// Required for react-router browserHistory
// see https://github.com/BrowserSync/browser-sync/issues/204#issuecomment-102623643
import historyApiFallback from 'connect-history-api-fallback';
import webpack from 'webpack';
import webpackDevMiddleware from 'webpack-dev-middleware';
import webpackHotMiddleware from 'webpack-hot-middleware';
import config from '../webpack.config.dev';

const bundler = webpack(config);

// Run Browsersync and use middleware for Hot Module Replacement
browserSync({
  port: 3000,
  ui: {
    port: 3001
  },
  server: {
    baseDir: 'src',

    middleware: [
      historyApiFallback(),

      webpackDevMiddleware(bundler, {
        // Dev middleware can't access config, so we provide publicPath
        publicPath: config.output.publicPath,

        // These settings suppress noisy webpack output so only errors are displayed to the console.
        noInfo: false,
        quiet: false,
        stats: {
          assets: false,
          colors: true,
          version: false,
          hash: false,
          timings: false,
          chunks: false,
          chunkModules: false
        },

        // for other settings see
        // http://webpack.github.io/docs/webpack-dev-middleware.html
      }),

      // bundler should be the same as above
      webpackHotMiddleware(bundler)
    ]
  },

  // no need to watch '*.js' here, webpack will take care of it for us,
  // including full page reloads if HMR won't work
  files: [
    'src/*.html'
  ]
});

Answer 1

好的，我找到了这种行为的原因，它与 webpack-hot-middleware 完全无关。
实际上是什么原因造成的 browserSync 插件。
在阅读了他们的文档后，我发现默认情况下，它有一个 ghostMode 选项设置为 true。

Clicks, Scrolls & Form inputs on any device will be mirrored to all others.

您可以通过将其设置为 false 来禁用它。 ghostMode: false.

希望对其他人有帮助。
