Interview Questions
SSG generates HTML at build time instead of runtime. Pages are pre-rendered and can be served from CDN. Provides fastest possible performance. Ideal for content that doesn't change frequently.
Use generateStaticParams for App Router or getStaticProps/getStaticPaths for Pages Router. Pages are built at build time. Support static data fetching. Content cached and reused.
Define dynamic paths using generateStaticParams or getStaticPaths. Specify which paths to pre-render. Support fallback behavior. Handle path generation.
Fallback controls behavior for non-generated paths. Options: false (404), true (loading), or 'blocking' (SSR). Affects user experience and build time.
Fetch data during build using async components or getStaticProps. Data available at build time. Support external APIs. Handle build-time data requirements.
Fastest page loads, better SEO, reduced server load, improved security. Pages can be served from CDN. Support global deployment. Lower hosting costs.
Implement path validation during build. Handle invalid paths. Support custom validation. Implement error handling for path generation.
Data fetched during npm run build. Available for static page generation. Support external data sources. Handle build-time operations.
Place assets in public directory. Support automatic optimization. Handle asset references. Implement asset management strategies.
Set revalidate time in fetch options. Handle on-demand revalidation. Support revalidation triggers. Implement revalidation strategies.
Implement pagination or chunking. Handle build performance. Support incremental builds. Implement data management strategies.
Implement build optimization strategies. Handle parallel generation. Support incremental builds. Implement caching strategies.
