Redirect subdomain to route

[scnroy]

Hi all!

I have a project configured with the subdomain es.domain.com. We're changing how we're handing localization and would like to redirect all traffic to from that subdomain to domain.com/es instead.

From what i've been able to tell, domain configuration allows for domain-to-domain redirects and redirect configuration in now.json allows for path-to-path or path-to-url redirects, but can't seem to figure out how to set up domain-to-route redirection.

I've been looking at setting redirects for a domain in the API docs as a hail mary, but when I send the following request, I get a server error response back. Works fine without the /es at the end of the redirect (as expected)

curl -X PATCH "https://api.zeit.co/v1/projects/<MYPROJECT>/alias" \
  -H "Authorization: Bearer <TOKEN>" \
  -d '{
  "domain": "es.domain.com",
  "redirect": "domain.com/es"
}'

Solution:

• Create a new project.
• Create a new now.json​ locally in an empty folder.
• Add the redirects configuration: https://zeit.co/docs/configuration#project/redirects

{
  "redirects": [
    { "source": "/(.*)", "destination": "https://domain.com/es" }
  ]
}

• Deploy.
  Assign "es.domain.com" as the production domain.
