链接到外部js文件不起作用

Question

I've been playing with nodejs, using websockets to communicate between server and browser. This is my working client code:

<script src="https://cdn.socket.io/socket.io-1.3.7.js"></script>
<script>
 var socket = io();
 socket.on('ida',function(data){
   console.log(data.news);
   socket.emit('vuelta',{news: 'answer'});
 });
</script>

Then why if I put

var socket = io();
 socket.on('ida',function(data){
   console.log(data.news);
   socket.emit('vuelta',{news: 'answer'});
 });

in a separated client.js file and link it like

<script src="https://cdn.socket.io/socket.io-1.3.7.js"></script>
<script src="client.js" type="text/javascript"></script>

it just doesn't work? In the browser's console, instead of showing data.news it says: Uncaught SyntaxError: Unexpected token < in client.js:1

It might be that you are not serving the file at all. Be careful to include it in the http server configuration, on your node server file.
