In this article, we explore how to leverage Next.js Incremental Static Regeneration (ISR) to keep static pages dynamically updated. This ensures your users get fresh content without rebuilding the entire site.
We’ll integrate JSON Server, a local mock API, to demonstrate the dynamic nature of ISR in real-time. The process includes configuring ISR to automatically revalidate pages, as well as demonstrating how changes in the mock API reflect on the front end without manual refreshes.
What We’ll Cover:
- What is ISR?
- Setting Up JSON Server
- Implementing ISR in Next.js
- Testing Dynamic Data Updates
What is Incremental Static Regeneration (ISR)?
Incremental Static Regeneration (ISR) is a feature in Next.js that allows you to update static pages after they have been generated, without needing to rebuild the entire site. This combines the benefits of static site generation (SSG) and server-side rendering (SSR) by serving static pages quickly while ensuring they stay up-to-date.
