This is a repository for the X16Rv2 hashing algorithm that is used by Ravencoin beginning October 1st, 2019.
You can use this repo for python or nodejs, or simply refer to the C files to see how the algo is implemented.
For python, run python setup.py install (virtualenv with python 3.7 is my recommendation)
For nodejs, you should be able to do npm install https://github.com/traysi/x16rv2_hash/
