This is an extension that uses [https://webpack.js.org]() to bundle and minify its sources. Using webpack will help to reduce the install- and startup-time of large extensions because instead of hundreds of files, a single file is produced.
Webpack is configured in the [`webpack.config.js`](./webpack.config.js)-file. Find annotation inside the file itself or refer to the excellent webpack documentation: [https://webpack.js.org/configuration/](). In short, the config-files defines the entry point of the extension, to use TypeScript, to produce a commonjs-module, and what modules not to bundle.
The `scripts`-section of the [`package.json`](./package.json)-file has entries for webpack. Those compile TypeScript and produce the bundle as well as producing a minified production build. Note, that there is no dedicated TypeScript-script as webpack takes care of that.
If you use `vscode-nls` to localize your extension that you likely also use `vscode-nls-dev` to create language bundles at build time. To support webpack, a loader has been added to vscode-nls-dev. Add the section below to the `modules/rules`-configuration.
A good sample is the shared config built-in extensions use: https://github.com/Microsoft/vscode/blob/bf5b0585d2a8759541690b2c564b96cb604ff92e/extensions/shared.webpack.config.js#L29-L51
