Beyond Components
React's component model is powerful, but large applications need more structure. Feature-based folder organization, shared design systems, and clear data-flow boundaries prevent the 'big ball of mud' that plagues many codebases.
State Management at Scale
Not every piece of state belongs in a global store. We recommend a layered approach: server state via React Query, UI state via local hooks, and only truly global state (auth, theme) in a lightweight context or Zustand store.
Type Safety as Architecture
TypeScript isn't just a linter — it's an architectural tool. Well-defined interfaces enforce contracts between modules, making refactors safe and onboarding faster.
Performance by Design
Code splitting, lazy loading, and memoization should be part of your initial architecture, not afterthoughts. React.lazy with Suspense boundaries gives you route-level splitting with minimal effort.
