Answer 1

There is no need for the client to ask for news. You can force the server if you want to emit every 1 second - as long as there are clients connected, they will receive updates. If there are no clients connected, you will see in the logs that nothing happens.

On the server

setInterval(function(){
    socket.emit('news_by_server', 'Cow goes moo'); 
}, 1000);

On the client

socket.on('news_by_server', function(data){
  alert(data);
});
