A cardiograph for your web application code base


Cardio is a web application health tool. It provides a snapshot (via a bunch of metrics) of how "healthy" your application is by measuring HTML/CSS/JS complexity.

npm install -g cardio

If you get installation errors for node-canvas, don't despair. It's an optional dependency used by Assetgraph to do some other cool stuff that isn't used in Cardio.

$ cardio »url-or-webroot-or-html-file« > output.json
$ cardio-report2array output.json # Reformats for metrics-friendly digestion
