# Dual Package Example
This is a demo project that compiles a package with [tsup](https://github.com/egoist/tsup), using named and default exports, as well as a subpath export.
It showcases an error related to the usage of default exports.
```shell
cd packages/package-a
pnpm check
```
After running this you should see this:
```shell
Build tools:
- @arethetypeswrong/cli@^0.12.2
- typescript@^5.2.2
🤨 CommonJS module simulates a default export with exports.default and exports.__esModule, but does not also set module.exports for compatibility with Node. Node, and some bundlers under certain conditions, do not respect the __esModule marker, so accessing the intended default export will require a .default property access on the default import. https://github.com/arethetypeswrong/arethetypeswrong.github.io/blob/main/docs/problems/CJSOnlyExportsDefault.md
