As of PSI 2.x, we expose both the PageSpeed Insights speed and usability scores. The latter is based on usability rules that score a page based on factors like the presence of a sensible mobile viewport.

For browsers that don't support performance.mark(), it falls back to performance.now() or Date.now(). In Node, it uses process.hrtime().

Hyperion plugins are designed to make inspection of your app quick and simple. Please see our annoucement blog post for a feature showcase.

Run this in a directory with a package.json, and it will take all the dependencies, devDependencies, and optionalDependencies, then npm install each one in a temporary directory with a temporary cache, then measure the install times. Each dependency is then listed from slowest to fastest.

The goal of the project is to permit to any company or individual to measure the power consumption of its tech services and get this data in a convenient form, sending it through any monitoring or data analysis toolchain. Scaphandre means heavy diving suit in 🇫🇷. It comes from the idea that tech related services often don't track their power consumption and thus don't expose it to their clients. Most of the time the reason is a presumed bad ROI. Scaphandre makes, for tech providers and tech users, easier and cheaper to go under the surface to bring back the desired power consumption metrics, take better sustainability focused decisions, and then show the metrics to their clients to allow them to do the same.

It is reactive and responds to changes in size, window-scroll and nested-area-scroll. Because there is no simple way to just get relative view coordinates. Yes, there is getBoundingClientRect, but it does not work when your content sits inside scroll areas whose offsets are simply neglected (as well as page scroll). Worse, mouse coordinates are relative to the viewport (the visible rect that contains the page). There is no easy way, for instance, to know that the mouse hovers over the upper/left corner of an element. This hook solves it for you.
