I wrote the WebSocket push example, every 5 seconds the server sends messages to the client browser (node. js and the browser)

node. JS Service Side

To install the WS module Support first

NPM Install WS

Service side (Server.js)

var GWS; var Websocketserver = require (' ws '). Server,    new websocketserver ({port:9000 }), Wss.on (function  (WS) {     = ws;    Console.log (' client connected ');    Ws.on (function  (message) {        console.log (message);        (Show, SetInterval);//Every 5 seconds the server pushes the message to the browser    }) ; function Show () {    gws.send (1122);}

shell> node Server.js

Browser client

<Script>    if(window. WebSocket) {Console.log ("Support"); }Else{Console.log ("not supported"); }    varws= NewWebSocket ('ws://localhost:9000'); Ws.onopen= function() {Console.log ("Open"); Ws.send ("Hello");    }; Ws.onmessage= function(evt) {Console.log (evt.data)}; Ws.onclose= function(evt) {Console.log ("websocketclosed!");    }; Ws.onerror= function(evt) {Console.log ("websocketerror!"); };</Script>
