Advanced1. What is Server-Side Rendering in Next.js?
BasicSSR generates HTML on the server for each request. Provides better initial page load and SEO. Next.js handles SSR automatically. Combines with client-side hydration for interactivity.
2. What are React Server Components?
BasicServer Components run only on server, reduce client-side JavaScript. Support async data fetching. Cannot use client-side hooks or browser APIs. Improve performance and bundle size.
3. How does hydration work in Next.js?
BasicHydration attaches JavaScript functionality to server-rendered HTML. Happens automatically after initial page load. Makes static content interactive. Preserves server-rendered state.
4. What is streaming SSR?
BasicStreaming SSR progressively sends HTML chunks as they're generated. Uses <Suspense> boundaries. Improves Time To First Byte (TTFB). Supports progressive rendering.
5. How do you handle SSR data fetching?
BasicUse async Server Components or getServerSideProps. Data available during render. Support server-only operations. Handle loading states.
6. What are the benefits of SSR?
BasicBetter SEO, faster initial page load, improved performance on slow devices. Support social media previews. Handle browser without JavaScript. Improve accessibility.
7. How do you access server-only code?
BasicUse 'use server' directive or .server.js files. Handle sensitive operations. Access server-side APIs. Support secure data handling.
8. What is server-side rendering cache?
BasicSSR cache stores rendered pages on server. Improves performance for subsequent requests. Supports cache invalidation. Handle cache strategies.
9. How do you handle SSR errors?
BasicUse error.js files for error boundaries. Handle server-side errors. Support fallback content. Implement error reporting.
10. What is the difference between SSR and SSG?
BasicSSR generates HTML per request, SSG at build time. SSR better for dynamic content, SSG for static. Trade-off between freshness and performance.
11. How do you implement SSR optimization?
ModerateUse streaming, caching, code splitting. Handle resource optimization. Support performance monitoring. Implement optimization strategies.
12. How do you handle SSR with authentication?
ModerateImplement server-side authentication checks. Handle protected routes. Support session management. Implement auth strategies.
13. How do you implement SSR middleware?
ModerateCreate middleware for request processing. Handle request transformation. Support middleware chain. Implement custom logic.
14. How do you handle SSR with third-party libraries?
ModerateHandle library compatibility issues. Support SSR-specific configurations. Implement integration strategies. Manage dependencies.
15. How do you implement SSR headers?
ModerateSet custom headers for SSR responses. Handle caching headers. Support security headers. Implement header management.
16. How do you handle SSR with state management?
ModerateImplement server-side state initialization. Handle state hydration. Support state serialization. Implement state strategies.
17. How do you implement SSR with i18n?
ModerateHandle server-side translations. Support locale detection. Implement translation loading. Manage language switching.
18. How do you handle SSR performance monitoring?
ModerateTrack SSR metrics and performance. Handle monitoring integration. Support debugging tools. Implement monitoring strategies.
19. How do you implement SSR testing?
ModerateCreate server-side rendering tests. Handle integration testing. Support unit testing. Implement test utilities.
20. How do you handle SSR caching strategies?
AdvancedImplement advanced caching patterns. Handle cache invalidation. Support distributed caching. Implement cache management.
21. How do you implement SSR error handling?
AdvancedCreate comprehensive error handling. Support error recovery. Handle error boundaries. Implement error reporting.
22. How do you handle SSR with WebSocket?
AdvancedImplement real-time features with SSR. Handle connection management. Support event handling. Implement WebSocket strategies.
23. How do you implement SSR security measures?
AdvancedHandle server-side security concerns. Implement XSS protection. Support CSRF prevention. Implement security strategies.
24. How do you handle SSR with microservices?
AdvancedImplement SSR in microservice architecture. Handle service communication. Support service discovery. Implement integration patterns.
25. How do you implement SSR instrumentation?
AdvancedCreate detailed performance tracking. Handle metric collection. Support debugging tools. Implement monitoring solutions.
26. How do you handle SSR with GraphQL?
AdvancedImplement server-side GraphQL operations. Handle query execution. Support data fetching. Implement GraphQL integration.
27. How do you implement SSR optimization patterns?
AdvancedCreate advanced optimization strategies. Handle resource optimization. Support performance patterns. Implement optimization techniques.
28. How do you handle SSR deployment?
AdvancedImplement deployment strategies for SSR. Handle environment configuration. Support scaling solutions. Implement deployment patterns.
29. How do you implement SSR documentation?
AdvancedCreate comprehensive SSR documentation. Generate API documentation. Support example implementations. Implement documentation updates.
