I am trying to get socket.io (Node library) to work.

I have the server-side js working, and it is listening. The socket.io website states simply:

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

<script>

  var socket = io.connect('http://localhost');

  socket.on('news', function (data) {

    console.log(data);

    socket.emit('my other event', { my: 'data' });

  });

</script>

This is nice, however, what JS file am I importing!?!

I went into the node_modules directory, where I installed socket.io through npm, and inside socket.io/lib/ is socket.io.js file. However, this is server-side (uses the phrase require(), which errors on the client).

I have spent an hour looking around and I can't get any client .js file to work.

What am I missing?
