Vercel Edge Middleware: Dynamic at the speed of static (historical)

This post announces the General Availability (GA) of Vercel Edge Middleware for Next.js, following a successful public beta with significant growth and adoption. It highlights the ability of Edge Middleware to run before the Edge Cache, enabling fast rewrites, redirects, and dynamic routing. The post details use cases for experimentation (A/B testing, personalization) and localization at the edge, leveraging built-in geolocation data. It also covers authentication at the edge for improved security and performance. The post notes that for new projects, Vercel Functions with Node.js runtime and Fluid compute are recommended, and Routing Middleware for request-time routing.
