Rolldown-Vite Implementation

This project now uses Rolldown-Vite, a high-performance Rust-based bundler that serves as the future foundation of Vite.

What is Rolldown-Vite?

Rolldown-Vite is a drop-in replacement for Vite that uses:

  • Rolldown: A Rust-based next-generation bundler
  • Oxc: High-performance JavaScript tools (parser, transformer, resolver, minifier)

Benefits

Based on real-world usage, Rolldown-Vite provides:

  • 3x to 16x faster production builds
  • Up to 100x less memory usage during builds
  • No esbuild dependency (uses Oxc for all transformations)

Implementation

The implementation uses pnpm's overrides feature to replace Vite with Rolldown-Vite:

{
  "pnpm": {
    "overrides": {
      "vite": "npm:rolldown-vite@latest"
    }
  }
}

This approach is recommended for meta-frameworks like Nuxt that list Vite as a peer dependency.

Current Status

  • ✅ Dev server running on port 9876
  • ✅ Production builds working
  • ✅ All Nuxt features compatible
  • ⚠️ Some warnings about sourcemaps (expected during technical preview)

Build Performance

Current build times:

  • Client build: ~4.3s
  • Server build: ~1.7s
  • Total build time: ~20s (including font downloads and Nitro server build)

Migration Path

Rolldown-Vite is currently in technical preview (Phase One). The roadmap:

  1. Phase One (Current): Separate rolldown-vite package for early adopters
  2. Phase Two: Changes merged into main Vite codebase with opt-in full-bundle mode
  3. Phase Three: Full-bundle mode becomes default for Vite
