Try to change your client code to:

<script src="/socket.io/socket.io.js"></script>
<script>
    var socket = io.connect();
    socket.on("connect", function() {
        socket.on('news', function (data) {
            socket.emit('my other event', { my: 'data' });
        });
    });
</script>

Also, in order to be able to go to /api/1... you need to register the corresponding app.get, e.g. as app.get("/api/*", ..., which would handle all the connections to /api/.... Otherwise it is expected that you will be getting the 404 error.
