We raised a $12.5M Series A round, led by Accel.

In this next stage, VoidZero is accelerating development on both our open-source projects and Vite+, the unified JavaScript toolchain.

This is only the beginning!

Finally, I've just merged PR for gunshi v0.27 docs!

v0.27 introduced a new plugin system, so documenting it and updating existing documentation accordingly took over a month and a half, with over 16,000 changes. I was so exhausted 😖

I sometimes think ‘Goする’ is strange as language because expression is broken. Go + Do? Verb + Verb ? It seem just Japanish …

I've just released out unplugin-vue-i18n v11.0.0 🚀
This release means that vue-i18n and nuxt-i18n can now support rolldown-vite. I believe nuxt apps using nuxt-i18n can achieve faster builds 💨
Ofcourse, it's also compatible with regular Vite 💪

97% build time reduction is massive, especially for on-demand server builds.

Also big shout out to @kazupon.dev for the collaboration! Don't miss his in-depth tech post (linked in the article).

PLAID Moved to @rolldown.rs & Cut Build Times by 97%

PLAID was using Rollup for server-side bundling, which could take up to 20s to complete each time! The team wanted to reduce wait times.

I introduced Rolldown in our real-world product and Rolldown solved our problems and gave us good results for UX, DX, and product launch.

Huge Thanks to @rolldown.rs team for their hard work!
