swc

npm Downloads

O swc é um compilador TypeScript / JavaScript super rápido escrito em Rust.

Performance

⚠️ Observação: A API transformSync no esbuild tem uma grande sobrecarga. Portanto, o swc é apenas mais rápido que o esbuild na API transformSync. Na API transform, o esbuild é cerca de 1 ~ 1,6x mais rápido que o swc.
