rauschma, 
What’s next for @vite?
Current issues:
- Relatively slow production build speed
- Inconsistency between dev [esbuild] & prod [Rollup] environments
- Network overhead of unbundled ESM during dev
Solution: Rolldown, a Rust port of Rollup
- Focus: performance with best-effort compatibility with Rollup
- Goal: switch to it in Vite with minimal impact on end users
Current status: early WIP
