Pure ESM package

The package linked to from here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

  1. Use ESM yourself. (preferred)
    Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
  2. If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
  3. Stay on the existing version of the package until you can move to ESM.
View Towards better developer

After many years of writing and thinking about developer documentation, I'm convinced that the discipline is still in its infancy. The goal of this document is to summarize my current opinions on the topic of documenting software.

When you ask a software developer what their favorite documentation is, you'll get a wide range of opinions with consensus centering roughly around the Stripe and Twilio documentation, as well as the documentation for open source software like Django, Perl, Flask, etc.

In academia, the uncontested master craftsman of developer documentation is Donald Knuth, who pioneered "Literate Programming"

At the frontier of developer documentation, we find projects like Eve and other projects inspired by Bret Victor's seminal "Inventing on Principle" video.

However, as folks at Dynamicland will often point out, the medium (in the McLuhan sense of the word) of software hasn't changed much since the days when code was written on teletypes: We still write software on fancy typewriters. The

Reach UI Philosophy

Reach UI is an accessible foundation for React applications and design systems.

The three equally important goals are to be:

  • Accessible
  • Composable
  • Stylable

How to use profiling in production mode for react-dom

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

Table of Contents

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.

Interaction tracing with React

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.

Redux Archeology and Design Notes

Design Goals

The main goal of this library is to prove that Flux can be implemented in a way compatible with full hot reloading (and explore how this can be done). You can run the example code with npm start, change action creators or stores, and the new logic will kick in before you refresh.
