Hello,

Railway itself does not offer any way to do the redirection at the platform level.

You would need to do this redirection in your code, likely with some middleware.

Best,
Brody

Thanks Brody, I was hoping for a slightly better walkthrough but I managed to figure this out.

For posterity, here's what I did:
1. Added both www and root domains to the Railway settings
2. Added CNAMEs for both in Namecheap
3. Wrote a middleware for NextJS:

```

import { NextResponse } from 'next/server';

export function middleware(req) {
  const host = req.headers.get('host') || '';

  if (host.startsWith('www.')) {
    const url = new URL(req.url);
    url.host = host.slice(4);
    url.port = '';

    return NextResponse.redirect(url, 301);
  }
  return NextResponse.next();
}

export const config = {
  matcher: '/((?!api|_next|favicon.ico).*)',
};

```

thanks
