Introducing Preact Signals: a reactive state primitive that is fast by default.
✅ feels like using plain values
🥳 automatic updates when values change
⏱ updates DOM directly (fast!)
🥹 no dependencies arrays

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.

the "sideEffects" config means packages can have their exported interface be a barrel without no performance hit (Vite dissolves re-exports, TS types are generated+cached so no source fan-out). And the packages made it so file moves usually don't change importer specifiers.
late reply but: no, not really. the DX win from the performance improvement massively outweighed any familiarity loss.
One thing we did to help was convert a bunch of "pseudo-package dirs" to real pnpm workspace packages with `"sideEffects"` configured.
And then the bonus was that doing it as a bundler plugin meant it had to be fast, which forced decisions like doing it all via a Rust lexer (no ast), and those all got reused to build the codemod tool that we then used to stamp the barrels out of the source after.
This got us to the end goal fast, but the main value was that it uncovered all of the incredibly nuanced bugs we had when barrel files were removed - module trees shifting between bundles, their exec timing changing, etc.
Lol it'll be a riot. We did this for 5.5M loc. Tooling was the only solution.
Thing that worked best: I built a "debarrel plugin" for our vite setup that dissolved barrel files so that before any code changes were applied we were already running the "no barrels" output.

Soon you will be able to roll Preact in vite without Babel github.com/preactjs/prefresh…

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.

or the copyright that tells you what year the LLM training data was collected rather than the date the page was last updated
lol maybe that's the shift - I'm using more frontends from the folks building LLM stuff, and that stuff is all rushed
