TIL: Vite 7 has reached stable adoption of Rolldown—a Rust-based bundler that replaces Esbuild and Rollup for production. Build times on my portfolio dropped by 45%. The transition is nearly seamless, though some legacy Rollup plugins need a compatibility shim.


```javascript
// vite.config.js in 2026
export default defineConfig({
  build: {
    bundler: 'rolldown', // Now the default in v7
    minify: 'oxc'      // Rust-powered minification
  }
})
```
