Thanks so much for the contribution! I left a few comments. My biggest question is whether or not we can share some code with our existing Neo4j functions to make long term support easier.

Also, it looks like some checks might be failing due to formatting issues. We have an included command to update everything to our formatting standards if you run yarn format.

Thanks!
