React recently introduced an experimental profiler API. This page gives instructions on how to use this API in a production release of your app.

Profiling in production

React DOM automatically supports profiling in development mode for v16.5+, but since profiling adds some small additional overhead it is opt-in for production mode. This gist explains how to opt-in.

This API was removed in React 17

Interaction tracing with React

React recently introduced an experimental profiler API. After discussing this API with several teams at Facebook, one common piece of feedback was that the performance information would be more useful if it could be associated with the events that caused the application to render (e.g. button click, XHR response). Tracing these events (or "interactions") would enable more powerful tooling to be built around the timing information, capable of answering questions like "What caused this really slow commit?" or "How long does it typically take for this interaction to update the DOM?".

With version 16.4.3, React added experimental support for this tracing by way of a new NPM package, scheduler. However the public API for this package is not yet finalized and will likely change with upcoming minor releases, so it should be used with caution.

Kinesis Freestyle (Terrible key switches. Mushy and un-lovable)
Kinesis Freestyle Edge (Traditional layout with too many keys, mech switches, proably too big to be tented easily/properly)
Matias Ergo Pro (Looks pretty great. Have not tried.)
ErgoDox Kit (Currently, my everyday keyboard. Can buy pre-assembled on eBay.)
ErgoDox EZ (Prolly the best option for most people.)

	OS X is the platform, Darwin is the operating system, and XNU is the kernel. Namely, the XNU kernel is the core piece of software that provides resource management, hardware abstraction, and scheduling. Darwin consists of the XNU kernel and basic software run by there kernel to provide a UNIX environment. OS X is built atop Darwin and provides a collection of frameworks and services that implement the user interface and main application libraries. Darwin and XNU are open source software, but the frameworks that make up the OS X platform on top of Darwin, are not.

	Ubuntu and other distributions are based on the Linux kernel and GNU software suite. Ubuntu is the platform, Linux + GNU is the operating system, and Linux is the kernel (more or less). Unlike OS X, Ubuntu doesn't have proprietary frameworks - everything is open source. And the distinction between the OS and platform are blurred as a result. That's why it's called a distribution, because what distinguishes Ubuntu from other Linux distributions is mo
