Living on the Edge
summary
Shows how to move small dynamic bits (a Geo-based banner) from Next.js SSR into an edge middleware that fetches a build-time static page, uses middleware methods like replaceText and setPageProp to inject localized copy, and caches at CDN for much lower latency. Covers Edge Functions from Netlify, Workers from Cloudflare and Cloudflare Smart Placement, Prisma Data Proxy and PlanetScale/Vitess handling up to a million open connections. Notes limits: lower CPU, smaller caches, extra cost, but measurable latency and carbon reductions.
