Node.js Question

failed to combine with angularJS

I want to create an instance message (chat) app, using Socket.IO and angualrJS.

my code is below. for some reason, the var socket = io(); command "cancel" the angluar script. i.e. if I delete this line the anglaur binding is working and {{ message }} will display its required value. However, when this code is as below, I see the expression: {{ message }} on my page.

how can I combine (on this example) with angularJS?


<title>My Chat</title>
<link rel="stylesheet" type="text/css" href="css/style.css">
<script src=""></script>
<div ng-app="myApp" ng-controller="myCtrl">
{{ message }}
<form >
<input autocomplete="off" ng-model="exampleText" type="text" />
<button type='button' ng-click="submit()">

var app=angular.module("myApp", []);
var socket = io();
app.controller("myCtrl", function($scope) {
socket.emit('chat message', = angular.copy($scope.exampleText));
return false;
socket.on('chat message', function(msg){
$scope=$scope.message+'<li>'+ msg;

As Krzystof Safjanowski said in his comment, it looks like you're forgetting to include the websocket script file in your html. If you look in your browser's console (Ctrl+Shift+J in Chrome and Firefox), you should see the relevant errors.
