I've built a website with PHP and hosts it on Apache server e.g. Bluehost.

Now that I've created a server-side app in javascript and run it with Node.js.

I want the app to power my website and what should I do? I do google and can't find solution.

On my computer I just in stalled node.js and WAMP. They run separately but work great together. I'd like use that app on the real website too. Any clue how can I achieve this without turning my computer into a web server (which I may consider this as the last resort).

My understanding now is I host my website normally and host an app on web hosting which node.js run and do what they called "pipe" it to my website.

Is the the right idea? How?
