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.

Hi Nicholas,

I saw you tweet about JSX yesterday. It seemed like the discussion devolved pretty quickly but I wanted to share our experience over the last year. I understand your concerns. I've made similar remarks about JSX. When we started using it Planning Center, I led the charge to write React without it. I don't imagine I'd have much to say that you haven't considered but, if it's helpful, here's a pattern that changed my opinion:

The idea that "React is the V in MVC" is disingenuous. It's a good pitch but, for many of us, it feels like in invitation to repeat our history of coupled views. In practice, React is the V and the C. Dan Abramov describes the division as Smart and Dumb Components. At our office, we call them stateless and container components (view-controllers if we're Flux). The idea is pretty simple: components can't

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

Previous versions used homebrew to install the various versions. As suggested in the comments, it's better to use pyenv instead. If you are looking for the previous version of this document, see the revision history.

$ brew update
$ brew install pyenv
$ pyenv install 3.5.0
$ pyenv install 3.4.3
$ pyenv install 3.3.6
$ pyenv install 3.2.6
$ pyenv install 2.7.10

$ pyenv install 2.6.9

Interesting part (unmounting & API) is at the end if you're not interested in the rest =).

Stress Tests

This animation proposal is just an attempt. In case it doesn't work out, I've gathered a few examples that can test the power of a future animation system.

1. Parent is an infinitely spinning ball, and has a child ball that is also spinning. Clicking on the parent causes child to reverse spinning direction. This tests the ability of the animation system to compose animation, not in the sense of applying multiple interpolations to one or more variables passed onto the child (this should be trivial), but in the sense that the parent's constantly updating at the same time as the child, and has to ensure that it passes the animation commands correctly to it. This also tests that we can still intercept these animations (the clicking) and immediately change their configuration instead of queueing them.

2. Typing letters and let them fly in concurrently. This tests concurrency, coordination of an array of ch
