To create a .d.ts file using webpack, you can use the dts-bundle-generator plugin. Follow these steps to create a declaration file for your webpack bundle:

  1. Install the dts-bundle-generator plugin by running the following command in your project directory:
1
npm install --save-dev dts-bundle-generator


  1. Create a webpack.config.js file in your project root directory with the following configuration:

const DtsBundlePlugin = require('dts-bundle-generator').plugin;

module.exports = {
  // Add your webpack configuration here...
  plugins: [
    new DtsBundlePlugin({
      name: 'my-library',
      main: 'path/to/your/entry/file.js',
      out: 'dist/my-library.d.ts'
    })
  ]
};


  1. Replace 'my-library' with the name of your library, 'path/to/your/entry/file.js' with the path to your entry file that exports the library's types, and 'dist/my-library.d.ts' with the output path for the generated declaration file.
  2. Run webpack to build your project and generate the declaration file:
1
webpack --config webpack.config.js


After running webpack, you should see the .d.ts file generated in the specified output path with the declaration for your webpack bundle.
