Caching
Section titled “Caching”Introduction
Section titled “Introduction”Caching is one of the most powerful performance tools in Next.js. The framework automatically caches data, rendered pages, and routes at multiple levels — reducing load on your database and serving content faster to users.
Why Caching Matters
Section titled “Why Caching Matters”- Reduces database load by serving cached results
- Improves page load time for subsequent visits
- Lowers server costs by reducing computation
- Enables Instant Loading with ISR (Incremental Static Regeneration)
Topics Covered
Section titled “Topics Covered”- Introduction — What caching means for Next.js
