Git at Scale (by cursor) has been one of the most interesting blog posts i've read in a while. It came right when I was frustrated with Shopify's internal git system.
As an exercise, I've implemented it over the weekend as open source. It's a single rust binary that you can point at any S3 type object store. It uses WAL and CAS primitives and requires no other data store.
It also implements bundle-uri so large git repos (like our mono) are very fast to download as a chain of static bundles. Also comes with basic familiar UX.

What if a signal on the server could just be a signal on the client?
Wrote about @_developit's mixed-signals - it reflects server-side Preact Signals to clients over any transport. Write your state once as a model, decide where it runs.
No fetch glue. No cache invalidation. Just signals.

Trying something new, we were working on a signals devtools extension but why limit ourselves to a browser extension? github.com/preactjs/signals/… - we're splitting it up and allowing you to render it anywhere with the proper adapter

Sidekick has 20+ new capabilities in this Edition. My favorite: it can create custom apps.
Just prompt Sidekick, and it writes the app code using Polaris UI with Admin API GraphQL queries and mutations.

Type performance optimization will always be under appreciated because it’s not the problem people think exists
It’s very important for complex type library as it can choke language server
At the certain complexity point, your library will not be usual at all if not careful

Oxlint Custom JS Plugins achieved internally.
In this example, I wrote a custom JS plugin that detects debugger statements, which was then detected by this JS plugin. 🌀
I see no performance regression when running through 10k+ files.
And don't forget all the core components are still in Rust.

For those asking about perf and interop, I'll be giving a talk about how it works at ViteConf in Oct. You should all come! xitter.cf/ViteConf/status/196363…
⚡ Speaker highlight: Jim Dummet, Core Team at @OxcProject
As a JS Developer, every tool seems to be rewritten in Rust. But If our tools migrate to a different language, will we lose the ability to customize them?
@overlook_motel explains how Oxc is aiming to "square the circle" by allowing customization via JS plugins but maintaining exceptional performance - with all the nerdy details!
Join him at ViteConf 🙌🏻

Fresh 2 has graduated to beta releases - essentially release candidates before a stable release.
Fresh can now act as a Vite plugin, opening the door to HMR, faster boot times, and Cloudflare deployments.
