For http protocol, it is about pulling, the client make pull request and then pull the response from the server through http protocol
Web socket protocol is established via http, it is bidirectional, the server can actively push the message to the client
Firstly, client initialize the connection with server to establish the channel in order to allow constant and continuous communication over TCP connection
A server can be connected with multiple clients
In the channel, the message sending will be bi-directional, client can send the message to the server, and the server can also send the message to client actively
From the inspector, it can be seen that the channel is established
In the channel, there are pull and push messages
It is a library that abstract web socket connections
It is required to install on both client and server-side
