The State of The State In The App Router

React has improved state management with built-in hooks like useState, useReducer, and useRef. Redux can still be used but it's recommended to avoid global state. Zustand is an alternative state manager that allows for easy creation of hooks. Proper architecture is important for accessing the global store. State managers can add extra bytes to the client's JavaScript bundle, so it's important to be selective in choosing libraries. Next.js and React routers are recommended for server-side rendering and personalized experiences can be achieved with spas.

React Query is a popular library with significant weekly downloads and positive user sentiment. It may have trade-offs like bundle size, but the actual size shipped is smaller. Bundle size optimization can be achieved by exporting only necessary features. React Query's declarative approach eliminates the need for custom data fetching solutions. It offers caching, request duplication, background updates, and more. RackQuery doesn't support normalized caching, but refetching after invalidation works fine. React's vision includes suspense architecture and server components. The documentation could be improved with a more structured flow. TensorStack Query can be a good choice for Next.js apps, but not necessary with mature frameworks. The 10 stack query and router concepts were discussed. Combining React Query with HTTP caching provides a robust caching solution.

Lessons From Adopting React Compiler

Akash Hamilwasia presenting at React Summit 2025, shares React Compiler learnings and works on an AI audio platform. Memoization in React helps optimize UI performance by preventing unnecessary re-renders. React Compiler offers automatic memoization through static code analysis. React rules emphasize purity and immutability. The compiler analyzes and memoizes code changes for optimization. React Compiler package usage improves performance through code analysis. Understanding reactivity issues is crucial for handling React state. Compiler optimization requires correct dependency arrays and usage of external libraries. Measure React Compiler impact using React Profiler for optimization and real user impact analysis.
