I’m trying to optimize our page speed, and one of the top recommendations is consistently related to the theme.min.js file. Is there some way to optimize this beyond the standard way it’s loaded in the Debut theme - and is it required for my store to function as it should?
Topic summary
Main issue: Google PageSpeed consistently flags the store’s theme.min.js as a top performance concern, prompting questions about whether it’s essential and how to optimize its loading.
Context: theme.min.js is the minified JavaScript for the Shopify Debut theme. Google PageSpeed is a performance auditing tool that highlights opportunities like reducing or deferring unused JavaScript.
Request: The original poster asks if theme.min.js is required for core store functionality and whether there’s a better way to load/optimize it beyond the Debut theme’s default setup.
Update: A respondent points to a related thread for guidance and notes they are actively working on optimizing Debut’s theme.js. They report the task is complex and time-consuming, with progress ongoing and no completed solution yet.
Status: No definitive answer provided on whether theme.min.js can be safely removed or how best to optimize it. The discussion remains open, with a suggested resource (linked thread) for further details and continued efforts to refine theme.js.

I have been optimzing debut theme as a side project, and optimizing theme.js is one of the to-dos.
Trust me, it’s not easy, i’ve spent hours and I’m nowhere near done.
