Start from a browser recording

Save a HAR file from the network tab of your browser, then turn it into a scenario.

vegaload import har -o recorded.vl.js recording.har
vegaload validate recorded.vl.js

By default it keeps the main site and drops images, fonts, style sheets and analytics. Add -include-static or -include-third-party to keep them. Always run validate first. It runs the scenario once with one user.
