Component Patterns

Advanced component composition patterns for flexible and reusable UI architecture

Compound Components

Build flexible components that work together while sharing state implicitly

jsx

⚛️ Compound components provide flexible API with implicit state sharing

💡 Use React.Children.map and cloneElement to pass props to children

📌 Great for building accordions, tabs, and dropdown components

⚡ Consider using Context API for deeply nested compound components

✅ Provides better component composition than prop drilling

Render Props & HOCs

Share component logic using render props pattern and Higher-Order Components

jsx

⚛️ Render props provide flexibility by inverting control to parent

💡 HOCs wrap components to add additional functionality

📌 Prefer hooks over HOCs in modern React for better composition

⚠️ HOCs can cause prop name collisions and wrapper hell

⚡ Render props avoid some HOC issues but can lead to callback hell

Custom Hooks Pattern

Extract component logic into reusable custom hooks for better code organization

javascript

⚛️ Custom hooks encapsulate stateful logic for reuse

💡 Start hook names with "use" to follow React conventions

📌 Hooks can call other hooks, enabling composition

⚡ Extract complex logic from components into hooks

✅ Test custom hooks separately from components

State Management Patterns

Patterns for managing application state effectively across component trees

Context & State Patterns

Manage global state and avoid prop drilling with Context API patterns

jsx

⚛️ Context provides dependency injection for React components

💡 Split contexts by domain to avoid unnecessary re-renders

📌 Combine Context with useReducer for complex state logic

⚠️ Context is not a replacement for all state management

⚡ Use memo and useMemo to optimize context consumer re-renders

Server Components Pattern

Leverage React Server Components for improved performance and DX

javascript

⚛️ Server Components run on server, ship zero JS to client

💡 Use "use client" directive for interactive components

📌 Server Components can directly access backend resources

⚡ Automatic code splitting between server and client

✅ Smaller bundles and improved initial page load

Performance Patterns

Optimization techniques to improve React application performance

Memoization & Optimization

Optimize rendering performance with memoization and React optimization APIs

jsx

⚛️ React.memo prevents re-renders when props haven't changed

💡 useMemo caches expensive computations between renders

📌 useCallback prevents function recreation on every render

⚠️ Premature optimization can make code harder to maintain

⚡ Profile first, optimize second - measure performance impact

Error Boundaries & Suspense

Handle errors gracefully and manage loading states with Suspense

javascript

⚛️ Error boundaries catch JavaScript errors in component tree

💡 Suspense handles async loading states declaratively

📌 Error boundaries must be class components (no hooks version)

⚠️ Error boundaries don't catch errors in event handlers

⚡ Combine Suspense with lazy loading for code splitting
