Wix App Registration

After creating any extension file, you must update the main src/extensions.ts file to register the extension with the app.

Why Registration Matters

The Wix CLI discovers extensions through the src/extensions.ts file — it's the single entry point that tells the build system which extensions exist. Without registration:

• Dashboard pages won't appear in the sidebar
• Site widgets won't show in the Wix Editor
• Service plugins won't be called during checkout flows
• Event handlers won't receive webhook deliveries
• Embedded scripts won't be injected into site pages

The most common cause of "my extension isn't working" is a missing .use() call in this file.
