  Automated, headless-able time-to-interactive measurement

  E.g.: tti-measure -u "https://greta.io" -u "http://127.0.0.1:9999/test.html"


  -u, --url       Compulsory arg    Urls to run the script on. Pass multiple -u to test multiple urls
  -r, --runs      Default: 2        Number of runs per page
  -t, --target    Default: 5000     Retuns non-zero if a test fails to load within the target time (ms)
  -a, --autostart Default: true     Autostart chrome
  --headless      Default: false    Should chrome run headless
  -cp,            Default: 9222     Chrome remote debug port
  -v, --debug     Default: false    Log verbosity
  -p, --profile   Default: 3gDsl    Network profile. '3gDsl' runs the tests on 3g and on dsl.

  Valid network profiles ['3g', 'dsl', 'uncap', '3gDsl']

Install

# Install 
npm i -g tti-measure

Then, just execute tti-measure -u "https://greta.io" to have an idea of the time-to-interactive on our homepage. It will run the page twice on 3g profile and twice on the dsl profile, and print an average.

$ tti-measure -u "https://greta.io"
