Question

I am making my first app with socket.io and nodejs just as socket.io offical web says, but the only thing I am seeing on the html after running node server.js is “Welcome to socket.io.” How can I fix this? Or why is this happening?

The code is as follows:

index.html

<script src="http://my.page/node_modules/socket.io/lib/socket.io.js"></script>
<script>
  var socket = io.connect('http://abogados.pages/');
  socket.on('news', function (data) {
    console.log(data);
    socket.emit('my other event', { my: 'data' });
  });

</script>

server.js

var io = require('socket.io').listen(80);

io.sockets.on('connection', function (socket) {
  socket.emit('news', { hello: 'world' });
  socket.on('my other event', function (data) {
    console.log(data);
  });
});

I would really appreciate any answer because if not, I can’t start with socket.io!

Welcome to socket.io!

1.You should add socket.io js file just like this,

<script src="/socket.io/socket.io.js"></script>

You don’t need to address an actual file. socket.io will take care about this

1. Hello world would be logged in your browser console, not in your document. Use Firebug or dev tools to check that out.

2. To do something by your self, emit an event from browser and then use socket.on('your event', function(){}) and console.log the data you received form client.

I’m new to node and socket.io too!
