How to implement the functionality to host any web app on a given domain through a single command similar to the discourse?

This is a very broad question - what have you done so far?

• Do you know how to create a subdomain manually, using A names and the like?
• Do you know how to use a reverse proxy to use that subdomain on a server?

Thanks for your reply @si
No I haven't implemented those yet, I have never worked with these kinds of stuffs used hosting server only.
But if you please let me know the path step by step which should I follow to implement these stuff, I will definately give it a try to implement those functionality.

It would be great help if you share some docs as well paths to implement these functionality.
Looking for your reply.
Thanks

I think you need to take a step back. It's great to have an end-goal but I think you're trying to run before you've learnt to walk.

• Have you bought a domain? If not, that's step one.
• Then go get a server from a cloud provider (Digital Ocean, AWS, GCP etc)
• Install Nginx and make a Hello world App on that server that serves content through a REST API
• Access the app using the servers public IP/port etc
• Learn to set-up your domain name using an Nginx reverse proxy
• Learn to set-up a subdomain

There are some very generic steps, because I don't know your skill level.
