Rendering Method Comparison
Same real database content, different rendering strategies. All demos use live production data to show authentic performance differences.
Server-Side Rendering (SSR)
Pages rendered on the server for each request - the production implementation
Performance Metrics
✓ Advantages
- • Perfect SEO - full HTML on first load
- • Fresh data on every request
- • Good Core Web Vitals
- • Works without JavaScript
⚠ Considerations
- • Slower Time to First Byte
- • Server load on each request
- • Hydration delay for interactivity
💡 Best For
Dynamic content that changes frequently and needs excellent SEO
Client-Side Rendering (CSR)
Content rendered entirely in the browser after JavaScript loads
Performance Metrics
✓ Advantages
- • Immediate interactivity once loaded
- • Reduced server load
- • Rich client-side interactions
- • App-like experience
⚠ Considerations
- • Poor SEO without additional setup
- • Large JavaScript bundle
- • Blank page until JS loads
- • Slower on mobile devices
💡 Best For
Interactive dashboards and tools where SEO is not critical
Static Site Generation (SSG)
Pages pre-rendered at build time and served as static files
Performance Metrics
✓ Advantages
- • Blazing fast load times
- • Excellent SEO
- • CDN cacheable
- • Minimal server load
⚠ Considerations
- • Data can become stale
- • Requires rebuild for updates
- • Not suitable for dynamic content
💡 Best For
Content that changes infrequently but needs maximum performance
React Server Components
Next.js App Router with React Server Components - the modern approach
Performance Metrics
✓ Advantages
- • Smallest JavaScript bundle
- • Direct database access in components
- • Automatic code splitting
- • Streaming and progressive loading
- • Zero bundle impact for server components
⚠ Considerations
- • Learning curve for mental model
- • Requires Next.js 13+ App Router
- • Some ecosystem compatibility issues
💡 Best For
Modern applications that need the best of all worlds

Key Metrics to Highlight
- • Bundle Size Reduction: RSC vs CSR shows ~80% reduction
- • Time to First Byte: Compare SSG (fastest) vs SSR vs CSR
- • SEO Effectiveness: View source comparison across methods
- • Core Web Vitals: LCP, CLS, and FID differences
Demo Flow Suggestion
- 1. Start with CSR demo (show loading state)
- 2. Show SSR version (immediate content, slower TTFB)
- 3. Demonstrate SSG (fastest, but static data)
- 4. Reveal RSC (best of all worlds)
- 5. Compare bundle sizes in DevTools
