This article will share with you how to use node. js to implement multi-room chat code based on socket. io + express. It is very practical and can be referenced by partners who need it.
Socket. io Introduction
Socket. IO is an open-source WebSocket library that implements the WebSocket server through Node.
Description: This chat room is based on node. JS implements the basic real-time communication functionality. Prior to this, there is no knowledge of node. js and MongoDB, but by flipping through blogs, you have basically achieved the desired results. Technology, should not

Step 1: Create a chat server.
First, let's write a Server:
var net = require('net')var chatServer = net.createServer()chatServer.on('connection',function(client){client.write('connection~~~\n')client.end()})chatServer.listen(2333)console.log('Server')

When a socket connects to the request, each socket will establish a socket, and the connected socket is not expressed, so each socket can only send i

I. The first version only sends information to the client
First, implement a simple version with the following code:
var net=require('net');var chatServer=net.createServer();chatServer.on('connection',function(client){ client.write('hi!\n'); client.write('bye!\n')
Nodejs is a simple chat server.
The implementation code is as follows:
Var net = require ('net'); var chatServer = net. createServer (), clientList = []; chatServer. on ("connection", function (client) {client. name = client. remoteAddress + ":" + client. remotePort; client. write ("Hi! "+ Client. name + "\ n"); clientList. push (client); client. on ("data", function (data) {// send data to the client broadcast (data, client); // clientList [I]. write
When we use PHP to write background code, we need to use Apache or Nginx HTTP server, with MOD_PHP5 modules and php-cgi.From this perspective, the entire "Receive HTTP request and provide Web page" requirement does not need PHP to handle at all.But for node. JS, the concept is completely different. When using node. js,
