Convert php website to nodejs Open

I have a website (veews.io) that's built primarily in php, i want to convert it to nodejs. I'm not super familiar with nodejs, but i understand javascript. It is built using bootstrap for the ui and that would need to stay. The end result would be a working site built on nodejs and the ability for me to understand the file structure and ability to modify/add what is there. Please don't make a generic offer without reading everything or even looking at the website.
