Follow up to #40: The initial version of the
benchmark-web-vitalscommand only comes with load time metrics, since other metrics are a bit more complicated to capture in a headless browser request, e.g. CLS and INP require interactions to happen and capture events throughout the page lifecycle, not just load time related.This is an early draft intended for iteration in the future.
You can already test this branch, but you will likely notice that you don't get data for CLS and INP for the reason outlined above (and each request will take ~30s as that it when Puppeteer will time out by default). Before this PR can be completed and merged, we will have to figure out how to trigger those metrics to be measured and exposed using the https://github.com/GoogleChrome/web-vitals library that is being used.
