In this video, we dive deep into Next.js Incremental Static Regeneration (ISR), demonstrating how to keep your static pages updated dynamically without rebuilding your app. We'll use JSON Server as a local mock API to fetch data, then showcase how to automatically revalidate pages at specified intervals. Learn how to trigger on-demand revalidation in ISR using a custom API route in Next.js when data changes, ensuring users get the latest content without manual refreshes.

We will cover:

⚙️ Setting up ISR in Next.js with getStaticProps()
🌐 Configuring JSON Server to serve dynamic data
⏱️ Setting revalidation intervals for automatic page updates
🎯 Live demonstration of data updates without rebuilds

This tutorial will guide you through creating a fully functional ISR example that adapts dynamically to content changes.
