Compare Redux with Modern Front-End State/Data Management and Propose an End-to-End Strategy

Context

You are building a React single-page application that:

• Consumes multiple REST APIs
• Must support offline viewing, pagination, optimistic updates, and error retries
• Needs a clear separation between local UI state and server-fetched state
• Currently uses Redux (classic or Redux Toolkit) and seeks an incremental migration path

Task

1. Compare Redux/Redux Toolkit with more modern approaches: React Query (TanStack Query) or SWR, Zustand or Recoil or MobX, and native Context.
2. Propose an end-to-end strategy for managing local UI state and server cache for this app.
3. Discuss trade-offs and decisions across:
   • Where to keep server state vs. local state
   • Caching and invalidation patterns (including pagination)
   • Performance (render churn, selectors, memoization)
   • Error handling and retry strategies
   • Testing and type safety
   • An incremental migration plan from an existing Redux codebase
