如何在 node.js 中创建可从不同计算机使用的聊天？

Question

I am currently learning node.js and I've just finished the chat using socket.io and express.js which works well. But now I'd like to expand this chat so that two users from differents computers could communicate.

I think it might be easier, first, using two computers on the same network but then I'd like the app to enable communication between two computers (each on a different network).

Is it possible using socket.io ? If yes, how ?

I guess there's something to change here :

server.listen(8080, function(){
    console.log('listening on *:8080');
});

If someone knows how, please let me know !

Thanks

You'll need to host your nodeJS application to a web server, giving everyone access to your website.

To achieve that you will need to use Cloud Application Platform, like AmazonWebService , or Heroku . You will be able to host your nodeJS application to a server same as you do to develop but it will be online.
