Lint checking is not enabled

This codebase has not been checked for syntax warnings, etc. It would be nice if it's been lint checked and fix all the warnings/errors in the code. My suggestion is to use eslint.

The python client is also not getting checked. Flake8 is commonly used to check against PEP8 (the Python style guide). Although, the current codebase is significantly different than PEP8 (different indentation and some of the casing).
