What is better to use for implementation with dynamic routes, dynamic content on the page and with a socket connection?

Question

Node.js

Good day!
Tell me what you need to learn, preferably easy to learn. It would be cool, even with "tasks" broken into sub-items.
To implement this task:

1) Access to the page at url/:id with a limited set of id
2) The page has dynamic content that is generated at the time of access by url, if there is such an id
3) The ability to use sockets on the page

Roughly speaking, the page is divided into two parts. On the one hand, you need to display the text that is received from the server (the text will not change for each specific id from point 1) and on the other hand, the text that will be constantly updated via the socket.
Not just text can be displayed, but some kind of html markup

Answer 1

If you need to limit something by id, then study the databases
