Comment system for blog on nodejs and mongodb?

Question

MongoDB

I want to practice with the mongodb + nodejs stack and make a comment system for posts on the site, maybe there are some algorithms or tutorials-manuals so as not to invent an airplane on a crutch.
I know that: -
In PHP, all sorts of save scripts to a file to a specific page, but it seems like something is written to the subd.
-Disqus is not suitable (this is not training for nothing)
Maybe someone has come across this, please share the link.
