React Patterns

Explore 11 React patterns, including composition with children, to build flexible components and manage state effectively.

Learn to build flexible React UIs with composition, passing components as props to create reusable containers, layouts, and wrappers.

Learn how to use the render props pattern in React to share reusable behavior and state logic, enabling consumers to control rendered UI.

Enhance React components with shared behavior like authentication or analytics tracking by wrapping them in a higher-order component.

Build multi-part components like Tabs and Accordion that share state while letting consumers control structure.

Learn to manage component state in React, distinguishing between controlled components where the parent owns state and uncontrolled components that manage their own.

Model complex UI states with state machines in React. Learn to use useReducer for explicit state transitions, avoiding boolean prop juggling.

Learn to implement React Error Boundaries to catch rendering errors in component subtrees, display fallback UI, and prevent app crashes.

Render modals, tooltips, and toasts outside the parent DOM tree while keeping React events and context intact.

Declaratively handle async data, lazy code, and streamed content with loading boundaries instead of manual flags.

Avoid context re-render storms by splitting state from actions, scoping providers, and reading with selectors.

Optimize React app performance by profiling with DevTools, then apply memo, useMemo, and useCallback to prevent unnecessary re-renders.

Learn 25 essential React best practices, including named slots, ReactNode vs. ReactElement, building compound components with Context, and splitting state and actions.
