Ratchet or Socket.io + Node.js?

Question

Node.js

What and why is it better to choose for the development of asynchronous features, primarily chat (s), events, when the numbers on the site are constantly updated.

- chat (complex, many groups with subgroups, chat control from the admin panel)
- notifications
- changing information on the page, without the actions of the user himself (example - exchanges)
- other features to revitalize the site

Ratchet or deliver Node.js and Socket.io ?

What is best suited for such purposes if the backend is on Symfony / Laravel? Why?

Answer 1

The wording of the question is very strange.
For websockets:
on the server - node.js and socket.io.
on the client - whatever. You can also Ratchet.
