Netlify Edge Functions are a full serverless runtime environment powered by Deno, running on Netlify's network edge. They offer improved performance and faster execution times compared to traditional serverless functions, making them suitable for shorter, performance-critical operations. Edge Functions can be used with plain JavaScript or TypeScript code and provide an execution limit of 50 milliseconds. They also enable powerful applications with unrivaled performance by executing closest to the users' locations. With Deno as the runtime, Edge Functions are highly performant and start faster than equivalent Node.js applications. The use of open-source solutions like Deno follows web standards, allowing developers to work together on common solutions. Netlify Edge Functions integrate seamlessly with the Netlify workflow, making it easy to deploy and manage edge functions. They offer advanced features such as chaining, middleware and transformations, streaming data, and access to environment variables, enabling developers to build powerful applications with a great First Contentful Paint score.
