+# Bundling Home Assistant Frontend
+
+The Home Assistant build pipeline contains various steps to prepare a build.
+
+- Generating icon files to be included
+- Generating translation files to be included
+- Converting TypeScript, CSS and JSON files to JavaScript
+- Bundling
+- Minifying the files
+- Generating the HTML entrypoint files
+- Generating the service worker
+- Compressing the files
+
+## Converting files
+
+Currently in Home Assistant we use a bundler to convert TypeScript, CSS and JSON files to JavaScript files that the browser understands.
+
+We currently rely on Webpack but also have experimental Rollup support. Both of these programs bundle the converted files in both production and development.
+
+For development, bundling is optional. We just want to get the right files in the browser.
+
+Responsibilities of the converter during development:
+
+- Convert TypeScript to JavaScript
+- Convert CSS to JavaScript that sets the content as the default export
+- Convert JSON to JavaScript that sets the content as the default export
+- Make sure import, dynamic import and web worker references work
+  - Add extensions where missing
+  - Resolve absolute package imports
+- Filter out specific imports/packages
+- Replace constants with values
+
+In production, the following responsibilities are added:
+
+- Minify HTML
+- Bundle multiple imports so that the browser can fetch less files
+- Generate a second version that is ES5 compatible
+
+Configuration for all these steps are specified in [bundle.js](bundle.js).
