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. --- *Created by Antigravity Orchestrator - Powered by Elite Web Ecosystem Wisdom.*
