Why Server Components Matter
React Server Components fundamentally change how we think about the client-server boundary. Instead of shipping entire component trees to the browser, we can now keep data-fetching and heavy logic on the server.
Migration Strategy
- Audit your component tree — identify which components are purely presentational vs. interactive
- Mark client boundaries — add 'use client' only where you need interactivity
- Move data fetching up — lift fetch calls to server components
- Stream where possible — use Suspense boundaries for progressive loading
Performance Results
Across 12 production applications we migrated:
- 42% reduction in JavaScript bundle size
- 2.1s improvement in Time to Interactive
- 67% fewer client-side API calls
