react-19

React 19 leverages the React Compiler to automatically handle memoization, making manual useMemo and useCallback hooks obsolete. You can safely replace these hooks with compiler-friendly patterns to improve code readability and reduce boilerplate.

Migrating to React 19 server components involves adopting a server components-first approach. Review existing components, remove manual memoization, apply modern context usage, and add explicit client directives only where interactivity is required.

React 19 best practices involve using new hooks introduced alongside the React Compiler, maintaining import hygiene, avoiding manual memoization, and embracing a server components-first architecture for optimal UI performance and maintainability.

forwardRef is no longer required in React 19. The React Compiler and new hooks handle refs natively, allowing you to transition away from forwardRef and reduce boilerplate while maintaining component performance and readability.

Using React 19 compiler patterns requires access to an existing React 19 project and knowledge of the new hooks and patterns introduced by the React Compiler to effectively optimize UI development, performance, and maintainability.
