-[legacy]
-# Legacy builds are served when modern requirements are not met and support browsers:
-# - released in the last 7 years + current alpha/beta versionss
-# - with global utilization above 0.05%
-# The lattermost query ensures that support for popular old browsers is not dropped too early
-# (e.g. IE 11, Android 4.4, or Samsung 4).
-#
-# In addition, legacy browsers must support some minimum features that cannot be polyfilled:
-# - ES5 (strict mode)
-# - web sockets to communicate with backend
-# - inline SVG used widely in buttons, widgets, etc.
-# - custom events used for most user interactions
-# - CSS flexbox used in the majority of the layout
-# Nearly all of these are redundant with the above rules.
-# As of May 2023, only web sockets must be added to the query.

-# 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).
