This plugin lets you use Yarn with esbuild. We use it in order to build Yarn itself!

1. Add the plugin to your dependencies:

yarn add @yarnpkg/esbuild-plugin-pnp

1. Reference it via your esbuild configuration build API only:

import {pnpPlugin} from '@yarnpkg/esbuild-plugin-pnp';

await build({
  plugins: [pnpPlugin()],
  // ...
});
