How HashiCorp developers iterate faster with ISR

Incremental Static Regeneration (ISR) dramatically reduces build times, allowing developers to deliver faster changes and better site performance. With Next.js 12.1, we’ve now introduced on-demand ISR, our most requested feature by developers shipping large-scale projects.
Bryce Kalow, a senior web engineer at HashiCorp, met with us to explain how HashiCorp's engineers use ISR and on-demand ISR to iterate quickly—while maintaining flexible sites and apps.
What is ISR?
ISR was introduced in Next.js 9.5 and is one of the rendering strategies available to Next.js developers. It allows you to rerun getStaticProps after your build has completed. This offers much more flexibility than traditional static applications. Enterprises especially favor ISR for building large sites and keeping content fresh and updated.
Traditional static site generation (SSG) forces an entire site rebuild with every (even minor) change. Since build times scale linearly with the number of pages you have, you could wait for hours for your site to build—think about a site with thousands or even millions of pages.
