Adding Node.js to PHP project

I'm building a movie database based on PHP and I recently found this very interesting tutorial https://milankragujevic.com/torrent-streaming-service-with-webtorrent-and-express so I'm having the idea to implement this Node.js based project on my PHP project.So that i can fetch only for magnets links and get streaming for all movies. For getting magnet link i didn't find a problem,i can get it using only movie name.So how can i implement Node.js to exciting PHP project
