// Null module shim for packages not available in the docs build.
// These are transitive dependencies of superset-frontend components that exist
// in the barrel file but are never rendered on the docs site.
// webpack needs these to resolve at build time even though the code paths
// that use them are never executed at runtime.
//
// This shim uses a recursive Proxy to handle nested property access chains:
// import ace from 'ace-builds'; ace.config.set(...) → works (returns proxy)
// import { useResizeDetector } from 'react-resize-detector' → returns noop hook
// import ReactAce from 'react-ace' → returns NullComponent
const NullComponent = () => null;
// For hooks that return objects/arrays
const useNoop = () => ({});
// Mock for useResizeDetector - returns { ref, width, height } where ref.current exists
const useResizeDetectorMock = () => ({
ref: { current: null },
width: 0,
height: 0,
});
/**
* Creates a recursive proxy that handles any depth of property access.
* This allows patterns like ace.config.set() or ace.config.setModuleUrl() to work.
*
* The proxy is both callable (returns undefined) and accessible (returns another proxy).
