react-19

To structure server and client components in Next.js 15, use server components by default for data fetching and apply the 'use client' directive explicitly for components handling user interactions to enforce proper boundary separation.

The React Compiler standardizes React 19 component and hook practices by automatically optimizing rendering rules, enabling robust component structures, and enforcing explicit imports across your TypeScript files.

The best way to separate data fetching and interactions is to scaffold a server component for data retrieval and a distinct client component for user input, ensuring strict server/client boundary separation.

Yes, you need to use explicit imports for React 19 hooks in TypeScript. Standardized React 19 patterns enforce explicit imports to maintain robust component practices alongside the React Compiler.

Yes, you can apply the React Compiler to existing Next.js 15 App Router projects. It standardizes React 19 patterns for routes and server actions, aligning component structure and rendering rules within your application.
