Cache components in Next.js: Faster pages with partial pre-rendering

Next.js 16 introduces Cache Components, enabling component-level caching that works with Partial Pre-Rendering. Instead of treating entire routes as static or dynamic, developers can mark specific components as cacheable using the 'use cache' directive while keeping request-specific sections dynamic. This allows predictable content like product catalogs to be cached and reused across requests, while personalized data streams in progressively. Combined with React Suspense, pages render immediately with a static shell, then stream dynamic sections as they complete, eliminating blank screens and reducing time-to-first-content from seconds to milliseconds.
