Code Review

This pull request introduces a comprehensive guide on building a scalable, feature-based React-Redux application architecture. The feedback identifies two issues in the documentation's code examples: a missing import for 'AuthProvider' in the 'App.tsx' snippet, and an incorrect usage of 'React.lazy' that fails to handle named exports from the feature module. Both issues have actionable code suggestions to ensure the examples are correct and copy-pasteable.

The example uses <AuthProvider /> on line 101, but it is not imported. Adding the import for AuthProvider from ./features/auth makes the example complete and copy-pasteable.

Suggested change

	import { featureFlags } from './config/featureFlags';
	import { CheckoutProvider } from './features/checkout';
	import { featureFlags } from './config/featureFlags';
	import { AuthProvider } from './features/auth';
	import { CheckoutProvider } from './features/checkout';

[gemini-code-assist]

Since React.lazy expects the dynamically imported module to have a default export containing a React component, and our feature-based index.ts pattern uses named exports (e.g., export { AuthProvider }), importing the feature directly like this will fail at runtime.

We should explicitly handle the named export in the lazy import.

Suggested change

	const CheckoutFeature = React.lazy(() => import('./features/checkout'));
	const CheckoutFeature = React.lazy(() => import('./features/checkout').then(module => ({ default: module.CheckoutProvider })));
