How to resolve it? I couldn't find the right loader in Webpack.org

webpack.config.js

const path = require("path");

module.exports = {
  resolve: {
    fallback: {
      fs: false,
      tls: false,
      net: false,
      path: false,
      zlib: false,
      http: false,
      https: false,
      stream: false,
      crypto: false,
      buffer: false,
      util: false,
      assert: false,
      dns: false,
      process: false,
      timers: false,
      url: false,
      child_process: false,
      string_decoder: false,
    },
  },
  entry: "./src/app.js",
  mode: "production",
  output: {
    filename: "app.js",
    path: path.resolve(__dirname, "dist"),
  },
};

package.json

{
  "type": "commonjs",
  "private": true,
  "scripts": {
    "build": "webpack",
    "start": "node ./dist/app.js"
  },
  "devDependencies": {
    "dotenv": "^16.0.3",
    "webpack": "^5.77.0",
    "webpack-cli": "^5.0.1"
  },
  "dependencies": {
    "mysql2": "^3.2.0",
    "ssh2": "^1.11.0"
  }
}

Solution

To process Node.js add-ons, such as ssh2, you need to use an appropriate loader. As it can be found on the Webpack page, you can use the node-loader like the following:

module.exports = {
  entry: "./src/app.js",
  mode: "production",
  output: {
    filename: "app.js",
    path: path.resolve(__dirname, "dist"),
  },
  module: {
    rules: [
      {
        test: /\.node$/,
        loader: "node-loader",
      },
    ],
  },
};

Don't forget to install it: npm install --save-dev node-loader
