RemoteEntry file size increased by ~7x

[sudhakar-selva]

Describe the bug

Noticed a substantial increase in remote-entry file size during our migration from v1 to v2 and observed this for our webpack-based application as well as the rsbuild one. It appears that most of the additional size is coming from the module federation SDK and runtime. Is this expected? How can we reduce the remote entry file size?

// rsbuild.config.ts
export default defineConfig({
  plugins: [
      pluginReact({
          swcReactOptions: {
              development: isDev,
              refresh: isDev,
          },
       }), 
      pluginStyledComponents(), 
      pluginBasicSsl()
  ],
  tools: {
    rspack(config, { addRules, appendPlugins }) {
      config.output!.uniqueName = 'unique_name'
      appendPlugins([
        new ModuleFederationPlugin({
          name: 'App',
          filename: 'remoteEntry.js',
          exposes: {
            //...
          },
          remotes: {
            // ...
          },
         /** Returns all dependencies from pkg.json and sets singleton for react*, react-router* and  couple other pkgs**/
          shared: getSharedDependencies(),
          manifest: false,
          dts: false,
        })
      ])

      return config;
    },
  }
});
