Is it possible to point a Vercel subdomain to a next.js page and not to a git separate branch?
I tried configuring a.subdomain.com on my Vercel domain subdomain.com and I just wanted to return a next.js page but Vercel insists I point to a git branch.
I could add a wildcard subdomain and handle routing within the frontend app, but I don't think routers like react-router offer a routing solution with subdomains because the subdomain is a limitation of the browser history api
What is the smart way to stand up a simple page under a subdomain in a next.js app?
