What are the differences between nginx, tornado, cowboy, node.js?

Question

Nginx

Please tell us how nginx, tornado, cowboy and node.js work differently. I already found out something, for sure, I could have learned all this from the network, but I'm fed up with plucking out bits of information from various video presentations and articles :( If I understand correctly, node generally transmits data through a third-party proxy http server. It's somehow strange, in my opinion. Sockjs can implement web sockets in any browsers, even in opera, unlike iostream. (This attracts me to it). Can nginx or other servers do the same? (All the same, nginx, it seems, is faster ) As far as I understand, in nginx one channel is constantly open, through which all clients communicate with the server at the same time.However, the question arises - is it safe?If not, what are the ways to protect yourself from external wiretapping?
What are the pros and cons of each server? What unique features do they have? Thanks

Answer 1

Compare warm to soft.
Nginx is a web server that can act as a proxy for different protocols.
SockJS is a library to work with the WebSocket protocol, both on the server and on the client.
Node.js is a V8-based runtime that can also be a web server itself. Yes, any server.
