I found that after uninstalling the apps, the page will have a lot of unused code, affecting the speed of the page. Is there any apps that can clear all unused code of the website?

Hi @TheSacredBear , You’ve got a much higher Google Lighthouse score than most of the stores I test. Apparently, a request to Google for your custom fonts can block the main page load by nearly a second. This is solvable, as fonts can be loaded after your main page load. You sometimes see this whe…

Hi, we faced the same issue that 3rd party apps loaded a lot of Javascript on every page, even tho the apps were sometimes only required on specific pages like cart, cms etc. We developed an app that helps to manage where to load 3rd party Javascripts and where to block it. https://apps.shopify.co…
