complex-state-management

What problem does it solve?

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.

Core Features & Use Cases

• Multi-Stage Loading: Track progress across multiple steps.
• Command Pattern: Centralized control over actions (playback, etc.).
• Ref Optimization: Avoid unnecessary re-renders with refs.
• Memoized Setters: Prevent extra renders in child components.
• Parallel State Updates: Batch related state changes for efficiency.

Quick Start

Create a ComplexPage component with a handleAnalyze function that demonstrates staged loading, and wire up a simple command pattern to control a secondary UI element.
