I need an advice. I work on a web app, that needs to send PNG images to users based on their achievements. The easiest way to do that is to construct an HTML that contains all the information, make a screenshot of it and finally upload it to the server. But this solution is extremely not optimal.
So I'm curious how to implement the same logic, but without frontend involvement in terms of image generation. I know that there are many commercial libs and services for that, but maybe there is some open-source more or less good libs for that.
I'm fine to work with Java, Scala, NodeJS or Golang.
Any advice is welcome!
