Incremental Static Regeneration: Static Sites on Steroids - Facundo Giuliani, React Advanced 2021

Discover the power of Incremental Static Regeneration (ISR) to improve the performance of static sites, with insights on atomic deployment, SSR, CSR, and more.

Key takeaways
  • Incremental Static Regeneration (ISR): a technique to improve the performance of static sites by generating pages at build time and revalidating them at runtime.
  • Atomic Deployment: a concept where changes are deployed in a way that minimizes downtime and ensures consistency across all pages.
  • Static Sites: deliver files as they are stored, without processing or rendering, which makes them fast, secure, and easy to maintain.
  • Server-Side Rendering (SSR): generates HTML content dynamically on the server, which can be used for pages that require heavy processing or complex logic.
  • Client-Side Rendering (CSR): generates HTML content dynamically in the browser, which can be used for pages that require interactive or dynamic updates.
  • Static Site Generators (SSGs): tools that automate the process of generating static sites, such as Next.js, Gatsby, and Hugo.
  • ISR in Next.js: allows developers to generate pages at build time and revalidate them at runtime using the revalidate property.
  • ISR Benefits: faster build times, reduced memory usage, and improved performance, especially for complex or large-scale applications.
  • ISR Use Cases: suitable for e-commerce platforms, blogs, and other applications that require dynamic content but still benefit from static site generation.
  • ISR Limitations: not suitable for applications that require real-time updates or high-traffic pages that need to be revalidated frequently.
