I think socket.io is good solution for you

Yes it is good, did some demo on it. But i want server to push user specific notifications, when some event (like/comment) occurs on post. Right now in my demo at some time interval i have to ask server for if notification exists for me or not.

If you have to ask server for notification, that's AJAX

With socket.io, that uses websocket, you can do that by idea of chat example:

Client need only to listen data pushed from server, that's same things with your notification

Hope that helps you

FWIW using socket.io in production in a mix of environments you'll have problems with random clients just plain not working and no idea how to fix it. At least with the current stable version of socket.io. Instead I recommend SockJS instead. We haven't had any of the random problems we saw with socket.io since switching. Also worth noting that the meteor framework switched for similar reasons.

"random clients just plain not working"  => what do you mean ? I don't find any problem with socket.io for now

I mean they just don't successfully make socket.io connections and don't trigger timeouts.

Most people don't until they start to gain users who actually let them know of problems. And it's impossible to debug those problems because there's no error messages and you can't emulate their network/environment perfectly.

There's a reason they re-wrote socket.io from the ground up for 1.0 (still un-released). Because the current version just doesn't work in enough places.

Thank you for your share. That means when there are too many connections at the same time, you can't make socket.io connection ? Any that must be big application ?

I'm very curios on this pb because I'm working on a project that uses socket.io

Thank you

No this was for a small startup - the number of connections wasn't the problem. The problem was unknown configurations at the end user's site (firewalls, anti-virus, different browsers, etc). You can't test for all that stuff, and you can't debug it, except to say that switching from socket.io to SockJS made all those problems go away.

I would use Server-Sent Events: http://www.html5rocks.com/en/tutorials/eventsource/basics/
