I am working on a MEAN stack SAAS application where I want to provide each user with their own unique subdomain. For example, I want the user John Doe to have the following subdomain to his name: johndoe.website.com.

The application is nearly ready pending this feature. I am looking for steps to accomplish this using NGINX and Node js in a manner that will lead to minimal changes to our existing code base.

I have searched the internet, and I was unable to find a resource that can serve as a step-by-step guide to help me solve this problem.

I know that the solution would involve the creation of Server Blocks to handle wildcard subdomains using NGINX, but I am not sure about the exact steps that will have to be implemented to get this done.
