# Do not use Edge Functions

Edge Functions are deprecated. Do not use them for new projects.

## What to use instead

Use [Vercel Functions](/docs/functions) with the **Node.js runtime** (the default). Node.js Functions provide:

- Full Node.js API support, including file system access, native modules, and all npm packages.
- [Fluid compute](/docs/fluid-compute) with automatic concurrency scaling.
- [Streaming](/docs/functions/streaming-functions) support.
- Global deployment with [configurable regions](/docs/functions/configuring-functions/region).

## Quick start

Export an async function from a route file. Node.js is the default runtime, so you don't need any runtime configuration:

```ts filename="app/api/hello/route.ts"
export async function GET() {
  return Response.json({ message: 'Hello' });
}
```

## Migrate existing edge function code

Remove `export const runtime = 'edge'` from your files. Node.js is the default runtime and the recommended choice. See [Vercel Functions](/docs/functions) for full documentation.

## Routing Middleware is not affected

[Routing Middleware](/docs/routing-middleware) uses the edge runtime by default. This is expected and supported. The deprecation above applies to standalone Edge Functions, not to Routing Middleware.
