React Patterns

11 examples to get you started with React Patterns -- 7 basic and 4 intermediate.

Build flexible, reusable containers and layouts by composing children instead of using inheritance.

Share reusable behavior or state logic while letting the consumer decide what to render.

Wrap components to apply cross-cutting concerns like auth, logging, or theming without modifying them.

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

Decide who owns a component's state, and support both controlled and uncontrolled use in library components.

Model UI with explicit states and transitions instead of juggling multiple isLoading and isError booleans.

Catch rendering errors in a component subtree and show a fallback instead of crashing the whole app.

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.

Profile first, then apply memo, useMemo, and useCallback only where they measurably help.
