I want to deploy a microfrontend made with React and Webpack 5 Module Federation. When I start the app locally and enter to http://localhost:5100/remoteEntry.js loads the js file with the right content. The problem is when I deploy the app (I’ve deployed on Vercel & Render), when I access to https://smart-form-jet.vercel.app/remoteEntry.js, it loads the js file but not with the exposed component I’ve indicated in the Webpack config, and not with the same content as locally.

This is my repo: https://github.com/aronilie/smart-form

This is my Webpack config:

const HtmlWebPackPlugin = require("html-webpack-plugin");
const ModuleFederationPlugin = require("webpack/lib/container/ModuleFederationPlugin");
const Dotenv = require("dotenv-webpack");
const deps = require("./package.json").dependencies;
module.exports = (_, argv) => ({
  output: {
    publicPath: argv.mode === "development"
    ? "http://localhost:5100/"
    : "https://smart-form-jet.vercel.app/",
  },

  resolve: {
    extensions: [".tsx", ".ts", ".jsx", ".js", ".json"],
  },

  devServer: {
    port: 5100,
  },

  module: {
    rules: [
      {
        test: /.m?js/,
        type: "javascript/auto",
        resolve: {
          fullySpecified: false,
        },
      },
      {
        test: /.(css|s[ac]ss)$/i,
        use: ["style-loader", "css-loader", "postcss-loader"],
      },
      {
        test: /.(ts|tsx|js|jsx)$/,
        exclude: /node_modules/,
        use: {
          loader: "babel-loader",
        },
      },
     // Other loaders
    ],
  },

  plugins: [
    new ModuleFederationPlugin({
      name: "smartForm",
      filename: "remoteEntry.js",
      remotes: {},
      exposes: {
        "./SmartForm": "./src/SmartForm.jsx",
      },
      shared: {
        ...deps,
        react: {
          singleton: true,
          requiredVersion: deps.react,
        },
        "react-dom": {
          singleton: true,
          requiredVersion: deps["react-dom"],
        },
      },
    }),
    new HtmlWebPackPlugin({
      template: "./src/index.html",
    }),
    new Dotenv(),
  ],
});

I would be very grateful if someone could help me, thanks.
