How to upload images to a folder in node.js/ajax/fetch server?

Question

JavaScript

Good morning. The task is to upload images to a folder. I implemented this in php, but I have no idea how to make them friends or rewrite them under node.js, I think if you try to make them friends, you need to keep php on a separate php server, which is very fat for a file 3 kb. Please help, maybe I searched badly or formulated the question in the wrong way, but I didn’t find articles of this kind, in YouTube everything in php is similar to articles.
