Process:

All the data is requested and processed via PHP and renders the HTML (the design). After that, my NodeJS takes a screenshot and generates an image, after that, it will be posted using Steem JS (Still working on this though as that's why I'm labeling my bot as "semi" because sometimes it fails so I manually post it)

I'm using "electron" + "electron-screenshot-service".

The code I have is similar with above example.
