My talk at @nextjs.org conf is online!
Go watch it, it contains two gems:
- The dangers and limits of URL state (to make you a better engineer)
- A live demo of how @nuqs.dev uses a declarative approach to type-safe and time-safe behaviours, in a composable way.

❌ If you unit-test a React 19 app, there’s a good chance a chunk of your CI time is being wasted on… 😴 setTimeout.
Wait, what? Yes!
React 19 introduced a minimum delay for showing a Suspense fallback, and hardcoded (!) it to 300ms.
Just 3 tests can waste almost 1 second on absolutely nothing!

I have an idea for my @reactadvanced.gitnation.org talk that would requiring building and shipping a new feature in @nuqs.dev next week (so I can actually rehearse with it).

🤔 What if there were a conference without talks? Just hanging out with OSS maintainers & builders, seeing what they’re working on, and learning cool stuff by actually talking to people.
🤯 What if hallway track turned into the whole event!

After a few months of targeted attacks on our ecosystem, followed by a confusing and rapidly changing response from @github.com, we wanted to put together some guidance for maintainers on how to help us all secure our supply chain together.

Been getting a lot of spam on the @nuqs.dev repo (sorry if you’ve been impacted 😓)
Reporting from a phone (where I catch most of reply notifications) is so obnoxious I just end up marking the spam as such and ban the author. But even that fails in some cases. 😡

I'm tired of explaining for a thousandth time why all of these errors mean you're using an archaic tool:
- Import errors on ESM;
- fetch/Request/Response/ReadableStream is not defined.

Type-safety is only as good as the runtime-safety that it's inferred from.
