A potential solution for cleaning up unused JavaScript (JS) in Webflow without causing the webflow.js file to stop working is to use the Custom Code section in the Webflow Designer. Here's how you can do it:

  1. Identify the unused JS: First, you need to identify the JS code that is no longer being used on your website. You can do this by thoroughly reviewing your custom code or by using a code analyzer tool to detect unused code.

  2. Remove the unused JS: Once you have identified the unused code, remove it from your custom code section. This will ensure that the unnecessary code doesn't impact the functionality or performance of your website.

  3. Disable or defer JS loading: Webflow's webflow.js file contains necessary scripts for the Webflow CMS and interactions to work properly. However, you can optimize its loading by disabling or deferring certain scripts that are not required on every page.

  • Disable specific JS for specific pages: If there are certain pages where you do not need specific JS functionality, you can disable them using conditional statements or logic in your custom code. This way, the webflow.js file won't load unnecessary scripts for those pages.

  • Defer non-critical JS loading: For JS code that is not essential for the initial page load, you can defer their loading until after the page has fully loaded. This can be achieved by adding the "defer" attribute to the script tag in the custom code section.

  1. Test thoroughly: After making any changes to your custom code, it is important to thoroughly test your website to ensure that everything is functioning as expected and that there are no errors or issues caused by the removed or modified JS code.

By effectively cleaning up unused JS in Webflow without affecting the webflow.js file, you can optimize your website's performance, improve loading times, and create a more streamlined user experience.
