Our review
Pros
  • Compiles JavaScript and TypeScript, with minification and source maps
  • Supports tree shaking, dead-code elimination, and shared-dependency chunking
  • Integrates with Next.js, webpack, Rspack, Jest, Parcel, and Deno
  • Compiles Clojure to JavaScript with Google Closure-compatible output and optimization.
  • Supports browser, Node.js, Web Worker, and bundle targets.
  • Includes browser and Node.js REPLs, npm dependencies, macros, and source maps.
Cons
  • The spack bundler is documented as slated for removal in v2
  • Bundling depends on spack, so its future path warrants attention
  • Support channels are community and documentation
  • The toolchain is centered on Clojure rather than multiple source languages.
  • Its feature set may be more than needed for projects that only require JavaScript.
  • Support channels are documentation and community.
