I’m looking to build a function into an existing JS software toolset that can read the latest release version of the toolset itself from GitHub.
I have a JS function already to read what the currently installed version is (from the ReadMe), and I want to compare the current version against the latest available on the repo.

Possibly reading the ReadMe file from the master branch of the GitHub could work, but I don’t know how to read in a file as text from a URL. The Repo is private / has Auth token requirement too.
