Custom subdomain per user

[ekevu123]

I am working on an app where users can create a profile page using a custom subdomain.

How would I handle routing? Do I have to use the cloudron API to add the subdomain to the app every single time? Do I set up a subdomain wildcard for my domain? Or is there any other solution for this?

Since you will need valid certificates for all domains, it makes most sense to go via the Cloudron api to add such subdomains to the app. The app internally then has to handle the delivery of content accordingly based on the virtual hostname.

uou could use wildcard aliases like in https://docs.cloudron.io/apps/#aliases . i.e All of *.userpages.com is redirected then to your app. Your app's route handler should then validate the hostname checking the Host header of the http request .
