 - `jitMode` [default: `false`] - Enables JIT compilation and do not refactor the code to bootstrap. This replaces `templateUrl: "string"` with `template: require("string")` (and similar for styles) to allow for webpack to properly link the resources.
 - `directTemplateLoading` [default: `true`] - Causes the plugin to load component templates (HTML) directly from the filesystem. This is more efficient if only using the `raw-loader` to load component templates. Do not enable this option if additional loaders are configured for component templates.
 - `fileReplacements` [default: none] - Allows replacing TypeScript files with other TypeScript files in the build. This option acts on fully resolved file paths.
-- `inlineStyleMimeType` [default: none] - When set to a valid MIME type, enables conversion of an Angular Component's inline styles into data URIs. This allows a Webpack 5 configuration rule to use the `mimetype` condition to process the inline styles. A valid MIME type is a string starting with `text/` (Example for CSS: `text/css`).
+- `inlineStyleFileExtension` [default: none] - When set inline component styles will be processed by Webpack as files with the provided extension.
