What problem does it solve?
This skill helps teams learn and apply React 19 patterns such as the use() hook, Server Components, Server Actions, and the React Compiler to build modern, high-performance applications.
Core Features & Use Cases
- use() hook: read promises directly in render to streamline data loading and reduce boilerplate.
- Server Components & Server Actions: structure fetching and mutations with clear server/client boundaries for scalable apps.
- useActionState / useFormStatus: manage action state and submission status in client components.
- React Compiler: leverage automatic memoization to minimize manual optimization.
- Ref as Prop pattern: simplify refs without heavy forwardRef boilerplate in React 19.
- Migration use cases: apply patterns when upgrading from React 18 to React 19 to improve performance and UX.
Quick Start
Enable React 19 patterns by starting with a server component that fetches data, then introduce a small client component for interactivity. Move form actions to server actions and use useActionState to reflect submission status. Experiment with the use() hook and Suspense boundaries to render data-driven components.
