Learn how to add Incremental Static Regeneration to a Jamstack site with Next.js: requirements, minimal page example, trust boundaries, operational checks, failure modes, and when to switch strategies.
When pages on a Next.js Jamstack site stay outdated after the configured revalidation period, pinpointing the culprit can be tricky. This guide walks through the most common ISR failures, offers a concise check‑list, and shows how to verify each step.
Learn how ISR lets you serve fast static pages while updating content in the background, with a concrete getStaticProps example, trade‑offs, and verification steps.
The App Router's real win is awaiting data in Server Components with route-segment revalidation — but caching defaults changed across versions. A worked example and how to verify behavior on your install.
Vercel Edge Functions shine for redirects, auth checks, and header logic close to users — but the V8 runtime's missing Node.js APIs and tight limits mean they fail badly for data-heavy work. Here's where the line sits.
Putting 'use client' on a page to silence a build error quietly reverts your route to a client-rendered SPA. Here's how to place the server/client boundary deliberately, with a worked filtering example and the composition pattern.
ISR lets Jamstack sites update individual pages without full rebuilds — but it trades immediate consistency for speed. A practical look at how it works, a Next.js example, and where it breaks.
When to use time-based ISR versus tag-driven revalidation, how fetch() caching behaves across Next.js 14 and 15, and how to keep server/client trust boundaries intact while maintaining fresh content.
ISR lets you keep static pages fresh without full rebuilds. This post explains when ISR is the right choice, walks through a product‑page example with time‑based and on‑demand revalidation, and discusses the staleness‑vs‑cost trade‑off.
