Learn how to keep a static site fresh without rebuilding the whole site by using ISR and on‑demand revalidation on Vercel. The post walks through configuration, an example API route, trade‑offs, and how to verify the results.
Guide to picking Node.js or Edge runtime for Vercel Next.js API routes, covering constraints, a comparison table, trade‑offs, example code and validation steps.
When a Vercel deployment returns a 502 Bad Gateway, the culprit is often a missing or empty environment variable. This guide walks you through the diagnostic steps, fixes, and when to seek escalation, ensuring your serverless functions run smoothly.
Learn how Vercel Edge Functions can slay round‑trip latency by running code in the nearest edge location, with a step‑by‑step example, trade‑offs, and real‑world usage tips.
Learn how to use Vercel's Incremental Static Regeneration (ISR) and on-demand revalidation to keep content fresh without sacrificing edge performance.
Learn how to implement Vercel Edge Functions to eliminate cold starts and reduce TTFB using the V8 runtime, including configuration examples and critical Node.js compatibility limits.
Stale ISR pages on Vercel? A step‑by‑step diagnostic guide that shows how to identify mis‑configured revalidate intervals, middleware conflicts, header mismatches, and query‑string pitfalls. Fixes and verification steps included.
Vercel Edge Functions run on the V8 engine for near-zero cold starts but lack Node.js APIs. Learn when to use each runtime, with a working middleware example and verification steps.
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.
