A few things learned along the way...
#1
not everything interacts well with "stateless"
JSConf CO @a0viedo
#2
when you have a hammer everything sounds like a serverless app
JSConf CO @a0viedo
#3
when asking for HTML, CSS or JS not everyone is super friendly
JSConf CO @a0viedo
Next steps
improve graphs for CSS colors (color bar is not taking frequency into account)
investigate if there are metrics (other than Lighthouse) on web accessibility that can be automated
analyze what tips can be automated the HTML results
JSConf CO @a0viedo
Next steps
add gallery section
compare two websites mode
add CSS framework detection
