Caching Smarter with Next.js - ISG + SWR + Server Actions

Описание: In this video, I walk through a hands-on demo application built with Next.js 15, designed to showcase caching strategies across both server and client components.

The app simulates a social media feed backed by a containerized PostgreSQL database, using features like:

🧱 Incremental Static Regeneration (ISR) with Next.js’s extended fetch() API
🔁 Cursor-based pagination using server-cached timestamps
⚡ Client-side caching with SWR and useSWRInfinite
🔄 Server Actions to revalidate and stream updated content

You'll see how static content is pre-rendered, cached, and revalidated to improve performance and minimize backend load. We also explore how server-side timestamps act as cache keys for paginated data, and how client-side revalidation keeps the UI up-to-date without heavy API usage.

If you’re looking to scale dynamic apps efficiently while delivering a smooth user experience, this architecture demonstrates the power of Next.js 15 in production-like environments.
