⚡ High-Performance Web Engineering

Source: Vercel Best Practices / Anthony Fu (Antfu) Engineering Standards

This skill focuses on "Elite-Level" web development: speed, zero-config DX, and scalable architecture.

🚀 1. The Vercel Way (Modern Stack)

  • Edge-First Thinking: Prioritize logic that runs on the Edge (Middleware, Edge Functions) to reduce TTFB.
  • Incremental Static Regeneration (ISR): Update static content without a full rebuild.
  • Server Component Patterns: Minimize client-side JS. Use use server sparingly and only where needed.

🛠️ 2. Antfu-Grade Developer Experience (DX)

  • Zero-Config Philosophy: Use modern tools like Vite, Vitest, and ESLint (flat config) to minimize boilerplate.
  • Composable Logic: Build small, single-responsibility functions (Vue Composables or React Hooks) that are highly unit-testable.
  • Type-Safety Everywhere: No any. Use Zod for runtime validation and strict TS configs.

📦 3. Monorepo & Scalability

  • Turborepo Master: Manage multi-package projects with intelligent caching and parallel execution.
  • Shared UI Libraries: Split the UI into a separate package within the monorepo for reuse across Web/​Mobile.
  • Package Modernization: Migrate from CJS to ESM. Ensure package.json exports are correctly defined.

🧪 4. Performance Auditing

  • Core Web Vitals: Monitor LCP, FID, and CLS. Chasing "100" on PageSpeed Insights is the goal.
  • Bundle Analysis: Use tools to find and remove "heavy" dependencies.
  • Preload/​Prefetch Strategies: Optimize asset loading for critical paths.
