From zero to void in under five minutes ⚡️
The docs link under getting started is a 404. @agent pls fix 🙏🏼
Happy to say that TC-39 has accepted the Error code property proposal as Stage 1 github.com/jasnell/prop... ... this works to standardize the pattern of adding the `code` property to Error objects using `new Error('...' { code: 'ERR_FOO' })`
![Code example showing the usage of Temporal.ZoneddateTime
```js
// London DST starts: 2026-03-29 01:00 -> 02:00
const zdt = Temporal.ZonedDateTime.from(
"2026-03-29T00:30:00+00:00[Europe/London]",
);
console.log(zdt.toString());
// → "2026-03-29T00:30:00+00:00[Europe/London]"
const plus1h = zdt.add({ hours: 1 });
console.log(plus1h.toString());
// "2026-03-29T02:30:00+01:00[Europe/London]" (01:30 doesn't exist)

Temporal is now Stage 4 at TC39 🎂🎂🎂
Thanks to all the other champions of JavaScript's new date-time API. It has been a wild ride over many years!

Node.js is moving to one major release per year starting with Node 27! 🚀
✅ Simpler: Every release becomes LTS.
✅ Predictable: Version numbers now align with the year.
✅ New: A 6-month Alpha channel for early testing.

It's not federation, it's not a p2p mesh. It's a secret third thing: practical.

Container Timing - a new W3C performance metric - has migrated from Bloomberg to the WICG Github org 🎉
@jason-williams.co.uk made the Bloomberg Terminal use this web metric to measure human-perceived time to start apps. We've found it more useful than existing metrics.

Pretty major improvement to website security! For those that can't use this immediately, FF 148 also brings Trusted Types to newly baseline which can go a long way in helping prevent XSS.
Chromium also looks set to follow shipping Sanitizer soon (probably 147).
Only half-heartedly to be honest. It was originally part of a refactoring that got scrapped but the first tries showed that it won’t be simple to infer the right types. I’ll take this thread as motivation to look at it again tomorrow though 🚀
Are you open to a contribution around this? At the time I wasn’t sure whether this is aligned with your idea and obvs queriesOptions is a terrible name … 😅
What we are missing is a way to share multiple queries together with the combine function. QueryOptions allows to share the whole singular payload (incl. select) but there is no easy way (type-wise) to achieve the same for multiple queries (incl. combine), which is the single source for custom hooks
That’s great and matches my experience 100%. One thing I am curious about is how you see using custom hooks around useQueries, because there is no queriesOptions API that allows for easy sharing multiple queries?
Schema benchmarks are here 🚀
This is great to see vercel.com/blog/we-ralp...
While specific runtime products may compete around features and performance, this kind of research on how to work around the inherent performance bottlenecks in web streams ultimately helps everyone.
That’s a very impressive list of fixes. 👏 Congrats to the team for shipping those.

👀 Chrome 145 DevTools has Soft Navigation markers
Nice DX improvement for building SPAs
I’ve noticed the same for EMs.
