useQuery or useSuspenseQuery is what creates the observer for the subscription. Without that, your component won't re-render when new data come in. Also calling a fetch during render is against the rules of react.

RFC: Unified Imperative Query Methods · TanStack query · Discussion #9135 Context Sometimes, APIs don’t evolve well. I’ve seen the situation a couple of times that we add an API, and we think it’s great, and then after some time, we add another API that does something si...

I want @tanstack.com Query v6 to be a release that will be easy to upgrade for 90% of users. Breaking behaviour for edge-cases, no application-wide syntax changes.

This RFC is likely the exception, but we want to ship it in v5 w/ deprecation notices and then remove them in v6.

was great meeting you. and awesome @tanstack.com devtools mention in that slide ❤️

we have a GitHub App to instrument GitHub Actions with Sentry for this:

knip failures in CI over time, interval = 3 hours. peak is 12 which is 4 times per hour

✂️ This is how often knip fails in CI in the @sentry.io codebase. Yes we use sentry to track our CI. All those spikes show a PR that would've left dead code behind if not for knip protecting us 🔥

Interval is 3h so there's up to 4 PRs / hour that need extra knipping!

Back home from React Paris 🇫🇷 and as always, it was an amazing experience. Thank you @aymenbenamor.bsky.social @ojilla.bsky.social @elian.codes for having me, I had a great time.

I think throwing a promise is deprecated and can't do all the things use() can, but I'm not the right person to give a definitive answer on that

I really hope not 😂

- We have to add a shim for React18
- We have to cache promises on the observer

Looking for volunteers that use @tanstack.com query with suspense. I have a PR that switches from throwing promises to `React.use` (with a shim for React18). Tests pass after changing them 😅.

Try it out pls🙏

On day 2, I gave a talk about ✂️ knip by @webpro.nl. This is me taking a photo of the audience, from both sides:

Dan on stage giving his talk "How not to use TanStack Query"

Tanner giving a talk about TanStack Start

There were so many @tanstack.com mentions at the conf that @sarahdayan.com made the joke to rename it to "TanStack Paris" 🔥. Shoutout to @neciudan.dev for having the bravery to give a TanStack talk in front of both @tannerlinsley.com and me 😂

First, I explored the city a bit on Wednesday. Saw the Pantheon and Notre Dame, went to lunch with @nicolas.dubien.me and @francoisbest.com. Gave my workshop "React Query - Beyond the Basics" at the Pigment office, then went for Dinner with @tannerlinsley.com, @beaussan.io and @brillout.com

Back home from React Paris 🇫🇷 and as always, it was an amazing experience. Thank you @aymenbenamor.bsky.social @ojilla.bsky.social @elian.codes for having me, I had a great time.

Hah.

Anything we can do to get @tanstack.com start to the list of meta frameworks 👀?

Is your testing suite hiding an inaccessible product? ♿

@tkdodo.eu drops a necessary truth bomb: "Test IDs are an accessibility smell." If your tests can't find elements the way a real user (or a screen reader) does, you aren't actually testing your app—you’re testing your implementation.
