JavaScript website builder, is it real?

Question

JavaScript

Hello. I want to develop a website builder with meteor.js. I need to make it so that when a new site is created, a salt is generated and a 3rd level subdomain (temporary) is created based on it. Then the user could register nameservers on my constructor and bind the domain, then so that he could go to it and open his user site. Realistically, no?

Answer 1

divide the task into subtasks
- task: route sites to the backend -
task: recognize which site came to the backend
- task: website builder

Answer 2

Why a meteor? How will search engines index content?
And there is already a site generator:
keystonejs.com
Generates routes, database and CMS. There are several modules that may or may not be included in the site. You can screw yours.
Try it, play around, maybe just make your own generator on this basis.
