This version of the builder is for creating plugins for Yarn 3.x. Yarn 3 plugins are not compatible with Yarn 2 installations, however Yarn 2 plugins are usually compatible with Yarn 3. If you wish to create plugins for Yarn 2, please use v2.x of the builder (yarn add @yarnpkg/builder@^2).


  • builder new plugin command for scaffolding new plugins
  • builder build plugin command for building complex plugins
  • supports TypeScript out-of-the-box
  • uses ESBuild internally, providing treeshaking, minification, and various other optimizations out-of-the-box
