How to include node_modules in assembly?

Question

webpack

Loaded modules do not get into the assembly - an empty function remains instead.

/*! no static exports found */
/***/ (function(module, exports, __webpack_require__) {

"use strict";

//# sourceMappingURL=...

/***/ }),

It is not possible to get the contents of an empty object during script execution. Although it's not clear to me where the empty object comes from, although the function does not return anything - is this the default value of the module?
Here is the webpack config:
webpack.config.js

const path = require('path');
const GasPlugin = require('gas-webpack-plugin');

module.exports = {
  mode: 'development',
  entry: './src/index.ts',
  devtool: false,
  output: {
    filename: 'script.js',
    path: path.join(__dirname, 'build'),
  },
  module: {
    rules: [
      {
        test: /\.[tj]s$/,
        use: 'ts-loader',
      },
    ],
  },
  resolve: {
    extensions: [
      '.ts',
      '.js',
    ],
  },
  plugins: [
    new GasPlugin()
  ],
};
