Online Store 2.0: Extend apps into the Online Store with theme app extensions
Shopify App Store
Effective June 29, 2021
Action required
App developers can now integrate their apps into the Online store with theme app extensions. A theme app extension is a bundle of app block definitions and supporting files. App blocks can be added, removed, and configured directly from the theme editor without having to touch a theme’s code. This means uninstalls are also cleaner, with ghost code automatically removed.
