Overview
Rolldown is a Rust-powered bundler for JavaScript that aims for Rollup compatibility and fast builds with a modern toolchain.
Pros
- Fast builds from Rust core
- Rollup-compatible plugin/API model
- Designed for modern JavaScript tooling
- Small focused bundler scope
- Good fit for Vite/JS ecosystems
Cons
- Relatively new ecosystem
- Smaller plugin ecosystem than Rollup/Webpack
- Less mature docs and examples
- May need migration for legacy setups
Verdict
Rolldown excels at fast JavaScript bundling while keeping a Rollup-like mental model. It suits teams adopting modern Vite-era toolchains that want speed with familiar APIs. The main trade-off is maturity: expect a smaller ecosystem and fewer battle-tested edge cases than established bundlers.
