You need server side scripts.
You need a web server to run your project. Why not use php instead.

I can run nodejs server locally

code learner , do you want to modify the file locally as well before converting it to json,
I have few codes for that on nodejs,
fs module will handle that file manipulation,
rest JSON.stringify() and a post Operation will take care , I ll try to write it fresh with comments đ

sorry for delay but using npm packages for everything made me so ignorant that I had to study again fir doing simple things, like request handling , body parsing etc đ

hence you ll get clumsy raw data, will update the repo as I find a fix
