Frontend Lab 🚀

Universal frontend technology comparison platform - Learn, compare, and contribute implementations across ALL frontend frameworks

🎯 Vision

Frontend Lab is an open-source, community-driven platform where developers can:

• 🔍 Compare React, Vue, Angular, Svelte, and more - side by side
• 📊 Visualize real performance metrics (Web Vitals, Bundle Size, Network Waterfall)
• 🎓 Learn through interactive demos and real-world patterns
• 🤝 Contribute implementations in your favorite framework

Test any component in any framework. In real time. With real metrics.

🏗️ Current Status: v1.0 MVP - React Focus

We're building the React MVP first to prove the concept, then expanding to other frameworks (v2.0+).

What's included in v1.0:

• ✅ React Performance Playground (SPA + Next.js)
• ✅ Interactive demos (React.memo, useCallback, useMemo)
• ✅ Data fetching comparison (CSR, SSR, RSC, Streaming)
• ✅ Real-time metrics visualization
• ✅ Framework-agnostic architecture (ready for multi-framework)

🎯 Demos (v1.0)

Performance Patterns

• React.memo - Prevent unnecessary re-renders
• useCallback - Optimize callback functions
• useMemo - Memoize expensive calculations

Data Fetching Strategies

• CSR - Client-Side Rendering (TanStack Query)
• SSR - Server-Side Rendering (Next.js)
• RSC - React Server Components (Next.js App Router)
• Streaming - Progressive rendering with Suspense

Real-Time Metrics

• 📊 Network Waterfall visualization
• 📦 Bundle size comparison
• ⚡ Web Vitals (TTFB, FCP, LCP, TTI)
• 🔍 SEO HTML preview
• 📈 Loading timeline animation

🤝 Contributing (v2.0+)

We welcome contributions! After v1.0 launch, you'll be able to:

1. Add a framework (Vue, Angular, Svelte, etc.)
2. Add a component (Dashboard, Form, etc.)
3. Improve visualizations
4. Enhance documentation

See CONTRIBUTING.md for guidelines (coming soon).
