Shopify now serves minified JavaScript files automatically

Platform

Effective August 12, 2021

As of August 2021, Shopify automatically minifies theme JavaScript when it is requested by the storefront. Minified JavaScript files are cached until the next time the underlying file is updated.

Minification improves storefront performance, leading to a better buying experience for customers.
