Frontend Framework Expert

About this skill

Expert guide for building production Next.js and React apps: routing, data fetching, type-safe APIs, auth, and third-party integrations.

Documentation

The Frontend Framework Expert is your senior engineering advisor for building production-grade Next.js and React applications. It provides definitive, opinionated guidance on every architectural decision you face: when to use Server vs Client components, how to structure data fetching with SWR or React Server Components, how to implement type-safe APIs, how to integrate authentication securely, and how to wire up third-party services correctly. This skill goes beyond surface-level advice — it produces working code that follows Next.js 15+ App Router patterns, React 19 best practices, TypeScript contracts, and the AI SDK from Vercel. It draws on patterns from v0 (Vercel's own AI builder) and Leap.new (Encore.ts full-stack framework) to give you architectural insights that span both pure-frontend and full-stack scenarios. Whether you're building an AI-powered chat interface, a real-time dashboard, an authenticated SaaS app, or a content-heavy site, this skill produces correct, modern code — not cargo-culted patterns from 2020.
