React Mastery Series – Day 31: Advanced React Architecture – Designing Large-Scale Applications

The React Mastery Series has transitioned from fundamentals to advanced architecture for large-scale applications. While small projects handle few components, enterprise applications require senior-level architectural planning. Key focus areas include state management decisions between Redux Toolkit and TanStack Query, alongside robust API architecture. Instead of direct fetch calls in components, large-scale systems implement service layers, Axios interceptors, token refresh mechanisms, and standardized error handling to manage multiple backend services and complex environment requirements effectively.
