Shopify has introduced a new policy requiring all apps to use theme app extensions instead of injecting Liquid code directly into a store’s theme. This is a strategic move aimed at improving performance, security, and long-term manageability of your online store.
What Are Theme App Extensions?
Theme app extensions are the modern, Shopify-recommended way for apps to integrate with your store’s theme. Instead of editing theme files, apps add features through modular blocks, embed blocks, and static assets. This method offers key benefits:
No manual code edits – Merchants no longer need to touch Liquid templates.
Easier to maintain – Updates are more stable and less likely to be broken by theme changes.
More secure – Apps don’t directly alter your theme code.
Faster to deploy – Install, configure, and position app blocks visually using the Shopify theme editor.
Universal compatibility – One setup works across all compatible Online Store 2.0 themes.
