this is, by a wide margin, the most lavishly cinematic account of rollup's history www.youtube.com/watch?v=azk-... (assembled from bits of footage leftover from a forthcoming vite documentary that i got to be a part of)

Grüne im Bundestag @gruene-bundestag.de · 07/01/2025
Die Treibhausgasemissionen in Deutschland sind 2024 laut einer Studie des #Agora Energiewende Think Tanks um 3% gesunken! Mit 656 Mio. Tonnen haben wir einen historischen Tiefstand erreicht – das sind minus 48% im Vergleich zu 1990. Der Hauptgrund dafür 👇 1/5 #Klimaschutz #Energiewende #Strompreis
Auf grünem Hintergrund ist grafisch ein Screen eines Jump and Run Computerspiels angedeutet. Am oberen Bildrand sind in typischer Retro-Grafik drei rote Herzen zu erkennen. Auf dem Motiv steht: „Level Up Klimaschutz: Emissionen 2024 deutlich gesunken!“ Am unteren rechten Bildrand ist die gelbe Sonnenblume der grünen Fraktion im Bundestag zu erkennen.

It took a while but here is the next attempt to introduce object property tree-shaking: Please install rollup@4.29.0-0 and tell me if performance is ok and if you find any bugs with the generated code. Otherwise, I will take it live in the next days.

So yesterday I decided to risk breaking everything by releasing property tree-shaking for Rollup. One day and two patch versions later, we are down to one user reporting a hanging build github.com/rollup/rollu.... If anyone can provide a reproduction, that would be amazing!

Object property tree-shaking is about to be finalized in Rollup! Just released rollup@4.27.0-0 that handles some really tricky scenarios when destructuring getters with side effects, including mutating the destructured object. Play around: rollup-cwwshxnz5-rollup-js.vercel.app/repl/?pr=542...

If you are using Rollup's JavaScript API via TypeScript, you can now use explicit resource management to call "await bundle.close()" for you.
A code sample containing
"await using bundle = await rollup(inputOptions)"
that shows that you do not need to call "await bundle.close()" if you generated it like this.

Just got the honors of processing a lot of donations to the open source ecosystem on behalf of the Sanity team. That felt really nice! ♥️

We are nearly ready at Rollup to release object property tree-shaking! But we need beta testers! Please try out rollup@4.25.0-0 And let us know: - Does it introduce any bug in the code? - Does it bundle much slower for you? What to expect rollupjs.org/repl/?versio... rollupjs.org/repl/?versio...
