A modular library for measuring the Web Vitals metrics on real users.
This was vendored from: https://github.com/GoogleChrome/web-vitals: v3.0.4
The commit SHA used is: 7f0ed0bfb03c356e348a558a3eda111b498a2a11
Current vendored web vitals are:
- LCP (Largest Contentful Paint)
- FID (First Input Delay)
- CLS (Cumulative Layout Shift)
This vendored web-vitals library is meant to be used in conjunction with the @sentry/tracing BrowserTracing integration.
As such, logic around BFCache and multiple reports were removed from the library as our web-vitals only report once per pageload.
- Bumped from Web Vitals v2.1.0 to v3.0.4
- Bumped from Web Vitals v0.2.4 to v2.1.0
- Remove support for Time to First Byte (TTFB)
- Added support for Cumulative Layout Shift (CLS) and Time to First Byte (TTFB)
- Added support for FID (First Input Delay) and LCP (Largest Contentful Paint)
