SSR vs CSR vs SSG vs ISR
Definition
Understanding the core differences, pros, cons, and appropriate use cases for the four primary rendering strategies in Next.js.
Explain Like I'm New
CSR = Rendered on user's phone (Slow initial load, great interactivity). SSR = Rendered on server on every click (Always fresh, slower server response). SSG = Rendered once when deploying (Absurdly fast, but data can get stale). ISR = Rendered once, but secretly rebuilds itself periodically (The best of both worlds).
Real World Example
Deciding architecture: Use CSR for a heavy drawing app. Use SSR for a stock trading platform. Use SSG for a privacy policy page. Use ISR for an e-commerce catalog.
