The following example shows how to add a response header in your Edge Middleware.
Your middleware
file should be placed at the root of your project. If you are using the src
directory, the file should be placed in the src
directory.
middleware.ts
import { NextResponse } from 'next/server';
export function middleware() {
// Store the response so we can modify its headers
const response = NextResponse.next();
// Set custom header
response.headers.set('x-modified-edge', 'true');
// Return response
return response;
}
