Mostly yes. It touches upon debugging unit tests and server-side code, as well as methodologies applicable to debugging in general, but the practical parts are almost exclusively client-side.
I build a "wrapper" for this (not public, quick&dirty code).
Transfer everything that could be logged via websocket to console and output and colorize it like I do it with a node app.
Reduces the time that I need to spend in browser for debugging (click, scroll, open trees, etc.), has same format and it saves much time.
I am sure somebody created a good lib for that on github.
