I haven’t looked in years but last time I checked there was a real lack of any well-documented guides of how to get things going. I managed just by trial and error but I would hardly call it fun, it left me wondering how anyone makes any complex extensions without going insane.

Maybe there’s a missing manual somewhere that I just couldn’t find, but it all just seemed pretty annoying/painful. Tooling and debugging experience was really lacking.

EDIT: This is specifically regarding chrome extensions.
