Next.js: Server-side Rendering vs. Static Generation
TL;DR
Web applications often face challenges in balancing performance and SEO (Search Engine Optimization). Next.js, a React framework, offers two rendering methods: Server-side Rendering (SSR) and Static Generation (SG).
✦ Why It Matters
Engineers can leverage Next.js to optimize web application performance and SEO based on content dynamics.
Key Takeaways
- Use Static Generation for pages that don't require real-time data.
- Implement getStaticProps to fetch data at build time for dynamic pages.
- Leverage Incremental Static Generation for updating content without full rebuilds.
- Consider Server-side Rendering for frequently changing content.
How It Works
Static Generation pre-renders pages into HTML at build time, allowing for faster load times and better SEO. Developers can use functions like getStaticProps to fetch data during the build process, ensuring that the content is up-to-date when the page is served.
For dynamic routes, getStaticPaths can be used to specify which pages to pre-render based on available data.
