## AI overview

Shopify explains how it addressed fragile import-map loading behavior at the web-platform level. The changes let theme and app developers interleave JavaScript modules and multiple import maps, improving correctness, caching, and developer experience.

## Source excerpt

Import maps are great for both performance and developer experience, but their original limitations made them hard to use, especially at Shopify's scale. We stepped up and pushed changes across the HTML spec, Chromium and WebKit to fix these issues at the web platform level. Now, developers can interleave JavaScript modules and multiple import maps on their HTML pages without worrying about correctness issues.
