Chrome extension that sets the attribute containertiming to the HTML node of the loaded documents, and registers an observer that dumps the container entries to console.log.

An easy way to try is:

1. Run in this folder npm run watch.
2. Run Chromium with `--enable-blink-features=ContainerTiming --load-extension=PATH_TO_EXTENSION/build/

Suggestions and pull requests are welcomed!.

This project was bootstrapped with Chrome Extension CLI
