Complex State Management Without External Libraries

Production patterns for managing complex application state in React without Redux, Zustand, or other state libraries. Includes multi-stage loading, command patterns, refs for performance, and parallel data fetching.

When to use this skill

• Building complex UIs with many interconnected states
• Need loading stages and progress tracking
• Implementing command patterns for centralized control
• Managing real-time updates and background operations
• Want to avoid Redux/Zustand overhead
• Building video players, editors, or multi-step flows
• Need precise performance control with refs
