Edge Functions connect the Netlify platform and workflow with an open runtime standard at the network edge. This enables you to build fast, personalized web experiences with an ecosystem of development tools.
Using TypeScript and JavaScript, you can modify network requests to localize content, serve relevant ads, authenticate users, personalize content, redirect visitors, and much more. Edge Functions also support a new generation of edge-first web frameworks allowing your entire app to run at the edge, dramatically increasing performance in many cases.
All this dynamic processing happens in a secure runtime based on Deno directly from the worldwide network edge location closest to each user for fast response times. Plus, you have the option to cache edge function responses for even faster response times. With Netlify, your edge functions are version-controlled, built, and deployed along with the rest of your Netlify site. This eliminates overhead and brings the power of Deploy Previews and rollbacks to your edge functions.
