# Rolldown Fast Rust-Based Rollup-Compatible Bundler

Configures Rolldown (developed by the Vite team): Rollup-compatible plugin and configuration API, high-performance module concatenation, treeshaking, and preparing for future Vite unified bundling.

## When to Invoke
Invoke this skill whenever you need to:
- bundle with rolldown
- rolldown config file
- rust rollup alternative

## Execution SOP & Rules
1. Install package: pnpm add -D rolldown.
2. Create rolldown.config.js: export default { input: 'src/index.ts', output: { dir: 'dist' } }.
3. Execute build: npx rolldown -c.
4. Observe multi-threaded compilation speed and inspect output bundle size.

## Verification Checklist
- Run local linting, syntax validation, and type-checks before reporting completion.
- Ensure all created or modified files adhere to workspace boundaries and avoid uncommitted secrets.
- Verify tests or build commands exit cleanly with return code 0.
