Why This Stack Wins
Vercel deploys your Next.js frontend globally on edge nodes. A headless CMS provides content via API. Together, you get sub-100ms page loads worldwide with zero DevOps.
ISR: The Best of Both Worlds
Incremental Static Regeneration lets you statically generate pages at build time AND update them without rebuilding. When content changes in your CMS, ISR revalidates only the affected pages:
// app/blog/[slug]/page.tsx\nexport const revalidate = 60; // Revalidate every 60 secondsOn-Demand Revalidation with Webhooks
For instant updates, use CMS webhooks to trigger on-demand revalidation:
// app/api/revalidate/route.ts\nimport { revalidatePath } from "next/cache";\n\nexport async function POST(req) {\n const { slug } = await req.json();\n revalidatePath(`/blog/${slug}`);\n return Response.json({ ok: true });\n}Preview Deployments
Vercel creates preview URLs for every git branch. Combined with CMS draft previews, your content team can review unpublished content on a real URL before it goes live.
Performance Results
- Time to First Byte: 20-50ms (edge cached)
- Lighthouse Performance: 98-100
- Global availability: 30+ edge regions
