javascript - 为什么需要重新加载页面才能在运行服务器时显示脚本？ (Gulp/Webpack/React)

Question

当我运行 gulp 时，所有内容都会编译到另一个 dist 文件夹中。页面会自动加载，但加载后，脚本会显示，直到我再次重新加载页面。不确定是什么问题。

gulp 文件

网络包

module.exports = {

  module: {
    loaders: [
      {
        test: /\.jsx?$/,
        exclude: /(node_modules)/,
        loader: 'babel-loader',
        query: {
          presets: ['react', 'es2015'],
            plugins: ['transform-class-properties']
        }
      }
    ]
  },
  output: {
    filename: "main.js"
  }
};

我不知道当你可以使用 webpack 时为什么要使用 gulp。我想你说的是react-hot-loader .
