I was hoping React Compiler would only rerender children if their sliced part of a larger state was updated - unfortunately all children gets updated :'(
Curios what the recommended way is to solve this while not opting out of concurrent rendering? playground.react.dev#N4Igzg9grgTg...

Having fun building my own scheduler component! Currently focusing on getting the interactions and layout feel right and smooth, with proper keyboard support. Recurring event support also in the works!

Toying with patterns to update css variable without triggering rerenders. Is the anti-useEffect crowd ok with this use case? (cc @tkdodo.eu)

@tkdodo.eu hi! would you be open to expose `useQueryResult.invalidate()`, instead of having to do `queryClient.invalidateQueries(query.queryKey)`? I'm noticing colleagues reaching for `queryResult.refresh()` simply because it's more easily available.

Two somewhat contradictory beliefs I hold:
1. You should absolutely overengineer your personal homepage/blog/projects. Experiment with as many things as you can as quickly as possible.
2. If you _really_ wanted to write that blog post, you'd figure it out with a .txt file. Don't overcomplicate it.

How did my fun weekend coding project turn into hours of reproducing bugs with their testing helpers and four issues on Cloudflare's workers-sdk? :(

It's fascinating watching developers discover they get better results using "A.I." if they prompt with tests, work in small steps, test continuously, review and refactor throughout, integrate often, and work in smaller teams, and attributing those results to autocomplete.

@liss.bsky.social Haven't finished listening to the episode, so apologies if this has been mentioned later, but if you have a USB-C port free on your current TS4 have you considered the 10G ethernet adapter? Then you would have 10G on all of your current devices as well. store.ui.com/us/en/catego...

Pope is a funny job like YES he works for maybe one of the most wicked institutions this world has ever seen but MAYBE he'll say fewer gay slurs repeatedly and SOMETIMES he'll shake his head no when a world leader flippantly suggests feeding children into a machine that makes energy drinks for cops

one of our (paid for) npm packages thought `6.2.20250316` was a good version format to introduce for nightlies and now I've had to educate them on semantic versioning and why this is a terrible idea and I was already quite annoyed with them
