Quick Reference
Modern Frontend Development - Comprehensive patterns for React 19, Next.js 16, Vue 3.5.
Core Capabilities:
- React 19: Server components, concurrent features, cache(), Suspense
- Next.js 16: App Router, Server Actions, ISR, Route handlers
- Vue 3.5: Composition API, TypeScript, Pinia state management
- Component Architecture: Design systems, compound components, CVA
- Performance: Code splitting, dynamic imports, memoization, Framer Motion animations
When to Use:
- Modern web application development
- Component library creation
- Frontend performance optimization
- UI/UX with accessibility

Implementation Quickstart
React 19 Server Component
Create an async page component that uses the cache function from React to memoize data fetching. Import Suspense for loading states. Define a getData function that fetches from the API endpoint with an id parameter and returns JSON. In the page component, wrap the DataDisplay component with Suspense using a Skeleton fallback, and pass the awaited getData result as the data prop.
Next.js Server Action
Create a server action file with the use server directive. Import revalidatePath from next/cache and z from zod for validation. Define a schema with title (minimum 1 character) and content (minimum 10 characters). The createPost function accepts FormData, validates with safeParse, returns errors on failure, creates the post in the database, and calls revalidatePath for the posts page.
