I'm wondering how 'no code' sites are able to host a unique website (defined by a subdomain) for each of their users, and have the the html and content updated when the user makes changes.
Are they running some form of 'npm run build && deploy_to_subdomain' every single time a change is made? How in the world would that work, since you can only upload 1 real build for a subdomain anyhow (because the real domain is the same)? Am I misunderstanding something?
The only other option I can think of is saving the changes to a database, and then just calling it & generating html when you hit the page. (Or vice versa) But that doesn't make sense and would be very slow.
Using React, Node.js, and Heroku if that matters.
