I'm having a web application build in PHP and I would like to add some real-time functionality to it. What I actually need is to control jut some parts (notifications "elements") of an existing page with nodejs. Would that be possible? I don't want to have to rewrite all the page on node.js.
I'm trying to find out if node.js could be the best approach for my needs (I never worked with it) or if it's better to use ajax long polling.
I read about using PHP and nodejs together, and about building one upon the other but I didn't found an answer about the situation I described before.
