应用程序之间的Webpack模块联合热重载

Question

我开始尝试使用 webpack 模块联合的微前端。 这是为了一个非常特殊的目的，因为在我们公司，我们开发大型软件，例如在角色基础访问控制中反应的仪表板，我希望每个部分（或几乎）都是一个单独的应用程序。

所以我设法实现了一切，只是我注意到当我修改远程应用程序时，应用程序容器的自动重新加载没有完成。我可以理解为什么，但我想知道是否有办法修改它？知道我不能只在远程应用程序上工作，因为它使用应用程序容器的冗余提供程序......

这是我的应用程序容器的 webpack 配置：

const ReactRefreshPlugin = require("@pmmmwh/react-refresh-webpack-plugin");
const HtmlWebpackPlugin = require("html-webpack-plugin");
const ModuleFederationPlugin = require("webpack").container
  .ModuleFederationPlugin;
const path = require("path");
const deps = require("./package.json").dependencies;

module.exports = {
  entry: "./src/index",
  target:"web",
  mode: "development",
  devServer: {
    contentBase: path.join(__dirname, "dist"),
    port: 3001,
    hot:true
  },
  output: {
    publicPath: "auto",
  },
  resolve: {
    extensions: [".js", ".jsx", ".json", ".ts", ".tsx"],
  },
  module: {
    rules: [
      {
        test: /bootstrap\.tsx$/,
        loader: "bundle-loader",
        options: {
          lazy: true,
        },
      },
      {
        test: /\.tsx?$/,
        loader: "babel-loader",
        exclude: /node_modules/,
        options: {
          plugins: ['react-refresh/babel'],
          presets: ["@babel/preset-react", "@babel/preset-typescript"],
        },
      },
      {
        enforce: "pre",
        test: /\.js$/,
        loader: "source-map-loader",
      },
      {
        test: /\.css$/,
        use: [
          'style-loader',
          {
            loader: 'css-loader',
            options: {
              importLoaders: 2,
              sourceMap: true,
            },
          },
            {
              loader: 'postcss-loader',
              options: {
                options: {}
              }
            },
        ],
      },
      {
        test: /\.s[ac]ss$/i,
        use: [
          'style-loader',
          'css-loader',
          'resolve-url-loader',
          'sass-loader',
        ],
      },
      {
        test: /\.(png|svg|jpg|gif)$/,
        use: [
          'file-loader',
        ],
      },
    ],
  },
  plugins: [
    new ModuleFederationPlugin({
      name: "appshell",
      filename: "remoteEntry.js",
      remotes: {
        mfsectors: "mfsectors@http://localhost:3002/remoteEntry.js",
      },
      exposes: {
        "./routes": "./src/routes",
        "./src/store/**": "./src/store"
      },
      shared: {
        ...deps,
        react: {
          eager: true,
          singleton: true,
          requiredVersion: deps.react,
        },
        "react-dom": {
          eager: true,
          singleton: true,
          requiredVersion: deps["react-dom"],
        },
      },
    }),
    new HtmlWebpackPlugin({
      template: "./public/index.html",
    }),
    new ReactRefreshPlugin({
      exclude: [/node_modules/, /bootstrap\.tsx$/],
    }),
  ],
};

这是我的应用程序远程 webpack 配置：

谢谢！ 抱歉我的英语不好^^'

Answer 1

您只需将其添加到主机的

webpack.config.js

:

{
...
  devServer: {
    ...
    liveReload: true,
    watchFiles: [path.resolve(__dirname, '..')], // make sure that hits your host app folder
  },
}

然后在遥控器上

webpack.config.js

：

{
  ...
  devServer: {
    ...
    devMiddleware: {
      writeToDisk: true,
    },
  },
}

谢谢@alexandre_anicio！工作正常

{
...
  devServer: {
    ...
    liveReload: true,
    watchFiles: [path.resolve(__dirname, '..')], // make sure that hits your host app folder
  },
}
