🎉 Excited to announce that I'm joining VoidZero as DevRel!
As I was following the project from early on, I couldn't say no to the chance when @evanyou.me reached out.
I can't wait to share all the incredible things lined up for @rolldown.rs, OXC, @vite.dev, and @vitest.dev 👀

Rolldown never ceases to amaze! ✨
Who doesn't like less code in the final bundle? Rolldown can remove a lot of different globals when they are side-effect free (and unused).
More than any other bundler right now, including Rollup!
And that's not the end, more tree-shaking improvements are on the way.

Did you know @vitest.dev has `expect.poll`? It reruns an assertion until it passes (or times out).
You can configure how many times the `expect.poll` callback should run with custom interval and timeout options!

I'm sure @e18e.dev is more than happy about that! Only as many native binaries as needed 👀
Are you using @rolldown.rs and want to parse a file?
Then you don't have to install Oxc separately. Just use Rolldown's `parse`/`parseSync` function. Rolldown re-exports it from Oxc while keeping it as part of Rolldown's binary.
This way, your dependencies stay lean!

The @rolldown.rs folks keep the chunking improvements coming!
🔧 A new Rolldown chunk optimization just landed!
When a module is both statically AND dynamically imported, Rolldown no longer creates an unnecessary extra chunk and inlines the import instead.
Same module, one less network request. ✅
Available since the latest Rolldown beta.

I had to show that feature in action and tell something about Hook Filters
The best is that it works framework-agnostic and gives great indicators without being a profiling pro

Did you know that @rolldown.rs's chunking algorithm got improved, leading to less chunks than before in different scenarios?
For example when you have two entry chunks and one imports from the other. Instead of having a "facade chunk", the chunks are now merged, resulting in less network requests.
