Scrape Carelink and Convert stream of carelink csv to text


Scraper and Parser for Medtronic pump, cgb and connected bg meter data.

Looking at the code

Primary entry-point is lib/index.js.

Parsing and fetching code is broken down by vendor-specific objects on the thing returned from lib/index.js.

That is currently just carelink right now.

Easiest way to see how to use the parser is to look at test/carelink/testParser.js

Libraries to be aware of

The code leverages the Rx library pretty extensively for stream processing. There is a lot to this library. You can read about its philosophy at or its documentation at

We implement a few extensions to it in the lib/rx directory. These extensions are added to the rx.Observable.prototype, so the usage can appear the same as if we are using a native rx method. If you are trying to figure out what a method does and you are unfamiliar with it/you cannot find the docs for it on the main RxJS page, make sure to check the various extensions under lib/rx.
