Here are some possible recommendations:

• Remove the unused "@@" directive at the top of the file.

• Consider using ES6 modules instead of traditional ES5 modules if the project is modernized to support it.

• Ensure that all CSS import paths have been adjusted so that they point to valid and up-to-date files within the project directory. This can help avoid issues with browser rendering errors and inconsistencies across various components.

• If this component or library is part of a larger frontend framework like Angular or ReactJS, ensure it's compatible with that environment specifically rather than having generic utility functions shared between projects due to their commonness among frameworks but being poorly implemented or not supported consistently.

Remember to always update dependencies and run npm outdated command from npm terminal before any significant changes. It will give you list of out-of-date packages as per current system version or specified latest versions in package-lock.json

Note: The actual recommendation might vary based on your project-specific requirements and setup.
