Definition:Incremental Static Regeneration (ISR)
Incremental Static Regeneration (ISR) allows updating static pages in the background without rebuilding the entire application.
Detailed Technical Explanation
Business Perspective
ISR enables scaling e-commerce platforms with millions of pages while keeping build times under a minute.
Technical Perspective
Configured via `revalidate` flags in Next.js, serving cached static pages while re-generating HTML asynchronously.
Real-World Example
Revalidating blog post pages every 60 seconds when new comments are submitted.
Common Architectural Mistakes
- ✗Low Revalidation Intervals: Setting 1-second revalidation intervals, negating static caching benefits.
