Generate documents and host them dynamically on subdomains

[alitainfotech]

Hello,

We are planning an application similar to GitBook. We are using nextra to generate documents for the user and that document needs to be hosted on subdomain so all other users can see the document.

Usecase: User will come and system will generate an organization for the user which will be subdomain for him. So for example user john came and created an organization of John-org then the subdomain would be john-org.mysite.io.
After that user will create document and publish. That published document should be accessed by the subdomain/project name over internet.

Now how it is possible to host an nextra application on subdomain dynamically?

Need help urgently
Regards
