The Problem with Static Site Generation — and How ISR Solves It
A simple question about the limits of Server-Side Rendering (SSR) led me down a deep rabbit hole… and that’s when I discovered something powerful: Incremental Static Regeneration (ISR) I always thought Static Site Generation (SSG) was enough — until I hit the scale problem. “What happens when your blog grows from 100 to 100,000 posts?” Do you rebuild the whole site every time? What about CDN caching? Real-time updates? Turns out, ISR is the scalable answer that combines the best of SSG and SSR. It’s efficient, flexible, and built for performance at scale.
