A modular library for measuring the Web Vitals metrics on real users.
This was vendored from: https://github.com/GoogleChrome/web-vitals: v3.5.2
The commit SHA used is: 3d2b3dc8576cc003618952fa39902fab764a53e2
Current vendored web vitals are:
- LCP (Largest Contentful Paint)
- FID (First Input Delay)
- CLS (Cumulative Layout Shift)
- INP (Interaction to Next Paint)
- TTFB (Time to First Byte)
This vendored web-vitals library is meant to be used in conjunction with the @sentry/browser
browserTracingIntegration. As such, logic around BFCache and multiple reports were removed from the library as our
web-vitals only report once per pageload.
