服務端和客戶端都需要引入：socket.io
socket.io的js下載：官網->blog去下載socket.io.js
|
socket.io的安裝，cmd執行命令：npm install socket.io
服務端程式碼：
var app=require('http').createServer(); var io=require('socket.io')(app); app.listen(8005); io.on('connection',function(socket){ socket.emit('news',{hello:'world'}); socket.on('my other event',function(data){ console.log(data); }); });
客戶端程式碼：
<html> <head> <title>websocket</title> <script src="socket.io.js"></script> </head> <body> <script> var socket=io('ws://localhost:8005'); socket.on('news',function(data){ console.log(data); socket.emit('my other event',{my:'data'}); }) </script> </body> </html>
