Insane

sdust.dev•89 days ago

A drop in without code change. That’s super impressive

pguilbert.dev•90 days ago

the dev build should also show an improvement, right?

callrouter.bsky.social•90 days ago

That's a fantastic improvement! 🎉 It's impressive to see such a significant speedup with zero code changes.

How does Rolldown + Vite compare to tools like https://www.farmfe.org/?

Are there any plans from your side to rewrite Vite too or move some Vite features to Rolldown?

Is the main goal of Rolldown to be a Rollup replacement or will it get more features?

Will it track (major) new Rollup versions?

It will be faster

I love these words.

Wow! In a test last week I managed to get it working by removing some plugins but bundling only went from 45s to 38s 😢. Nice but still not the improvement I was hoping for (esbuild bundles the same ~6k modules in 4-5s). But looking forward to the progress. And bundle size is top prio for us.

Is there a fork or branch i can pull down of Vite that uses Rolldown yet >->

Thank you, you dropped this 👑

evanyou.me•90 days ago

Note so far the focus is mostly on compatibility - still many places where we can further reduce overhead compared to raw Rolldown!

kentcdodds.com•90 days ago

Love to see this!

scriptedalchemy.bsky.social•90 days ago

Whats your raw rolldown speed expected if js wasn't bottlenecking it? Pretty good speedup for drop-in. Rspack does about 3x when babel loaders are used heavily.

evanyou.me•90 days ago

Also another important note: I realized the speedup isn't as impressive because the Vue SFC playground is an interesting case of small number of big modules: the project is 53 modules only with a few huge pre-bundled chunks (vue/repl bundles the monaco editor) from dependencies.

evanyou.me•90 days ago

This limits the parallelization advantage of a Rust bundler vs a JS one. In projects that have thousands of modules, the speedup will be *much* more siginificant.

wojtekmaj.pl•90 days ago

Interesting insight! So module resolution is now fast enough so that the benefits of parallelization outweigh the benefits of not resolving too many modules?

evanyou.me•90 days ago

Number of modules has never been a bottleneck for build, it is during dev because of the HTTP request overhead, not resolution

fancypenguin.party•89 days ago

Curious of memory difference too

itayperry.bsky.social•89 days ago

Hi there @evanyou.me, this is amazing! Do you know when will rolldown become a native/built-in part of vite? I mean, if that’s the plan.

josephinethuy.bsky.social•90 days ago

incredible progress! A ~3x speedup with 0 code changes is seriously impressive, great work optimizing with rolldown-powered-vite. I'd love to connect and learn more about your workflow. Mind giving me a follow back? Also, I’m currently exploring new areas to invest in—any insights/ recommendations?
