React Context Patterns for State Management

React Context provides a way to share state without prop drilling. Here's how to use it effectively.

Multiple Contexts Composition#

Best Practices#

Performance:
✓ Split state and actions into separate contexts
✓ Memoize context values
✓ Use selectors for fine-grained subscriptions
✓ Avoid putting everything in one context

Organization:
✓ Create custom hooks for context consumption
✓ Throw helpful errors when used outside provider
✓ Co-locate context with related components
✓ Use TypeScript for type safety

When to Use Context:
✓ Theme/UI preferences
✓ User authentication state
✓ Locale/i18n settings
✓ Feature flags

When NOT to Use:
✗ Frequently changing data
✗ Large state objects
✗ Server state (use React Query)
✗ Complex state logic (use Zustand/Redux)

React Context is powerful for sharing state across components. Split contexts for performance, use custom hooks for clean consumption, and consider compound component patterns for flexible APIs. For complex state or frequent updates, consider dedicated state management libraries.
