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 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.
Learn how Vercel's Incremental Static Regeneration works with the Next.js App Router: configure time‑based revalidation, add instant on‑demand updates via webhooks, understand the stale‑while‑revalidate trade‑off, and verify the behavior with concrete commands.
Stop shipping data-fetching logic to the browser. Learn how to use Next.js Server Components and Streaming to reduce bundle sizes and improve TTFB.
Goal: Verify whether Framer Motion's AnimatePresence component triggers its exit animations when a Next.js App Router route is unmounted via navigation. Constraint: AnimatePresence only animates children that it directly removes by tracking their key props, while the App Router removes route segments through its internal router rather than a React state chan
In Next.js (version 13.4+), the useFormStatus hook is designed to provide the pending boolean state to child components of a form during the execution of a Server Action. While the hook functions as expected during a standard HTML form submission, there is uncertainty regarding its behavior when the Server Action is triggered programmatically. Specifically,
In a Next.js App Router project (version 13 or later) using Middleware for centralized authentication, the goal is to guarantee that routes under a protected prefix such as /dashboard are never reachable without a valid session. The matcher configuration is intended to scope the security check to those paths, while the Edge Runtime restricts certain Node.js
ISR revalidation in Next.js 14+ app router triggers server-side incremental regeneration on the next request, but edge caches operate independently of the server cache layer. This creates a dual-layer staleness window where content may be stale at the edge even after a `/api/revalidate` trigger, because edge caches honor their own `s-maxage` or `max-age` TTL
Data Cache Consistency Next.js App Router utilizes a server-side Data Cache that persists across deployments, managed via revalidatePath and revalidateTag . While these functions purge the internal Next.js cache, the interaction with external Content Delivery Networks (CDNs) introduces a synchronization boundary. CDN Integration Constraints When utilizing co
