Wix App Builder

Helps build extensions for Wix CLI applications. Covers all extension types: dashboard pages, modals, plugins, menu plugins, custom element widgets, Editor React components, site plugins, embedded scripts, backend APIs, events, service plugins, and data collections.

Scaffolding is owned by the Wix CLI. Use wix generate --params for every supported type. It generates files and, where applicable, builder boilerplate, UUIDs, and src/extensions.ts registration. HTTP endpoints are discovered from files and need no registration. This skill provides the decision logic, API guidance, configuration semantics, and business-logic patterns that fill in the generated stubs.
