Craco Plugin UI5 Webcomponents

This is a craco plugin that improves the bundling of ui5-webcomponents for create-react-app version 4.

UI5 Webcomponents for react is made of several packages. Each package produces its own locale and language specific message bundles. By design each bundle is loaded asynchronously with the result of loading only the needed stuff. But this leads to several async requests in the browser which may impact your rendering time and increases the TTI (Time To Interactive).

This plugin reconfigures webpacks default code splitting mechanism to group all of those language and locale specific files of all ui5 webcomponent packages by language. The files are still loaded asynchronously but instead of fetching multiple files only one file will be loaded. The tradeoff is an increase in the resulting bundle size that will be loaded asynchronously.

Note: This plugin is only applied for production builds.
