Next.js Incremental Incremental Static Regeneration
Updated pages without redeploying
Incremental Static Regenertion (ISR) is a way to rebuild parts of your page without rebuilding your entire project.
You can rebuild pages on a schedule or based on an event. I chose re-building on an event, as i’m using ISR to rebuild the pages of my blog when my blog posts change.
