Adding Response Headers in Edge Middleware

Learn to add response headers at the edge.

Add Header Example

Below is the code from middleware.ts showing how to add response headers at the edge:

import { NextResponse } from 'next/server'

export default 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
}
