$ attw --from-npm universal-cookie

universal-cookie v7.2.2

Build tools:
- typescript@^5.6.3
- rollup@^4.24.3

❗️ The resolved types use export default where the JavaScript file appears to use module.exports =. This will cause TypeScript under the node16 module mode to think an extra .default property access is required, but that will likely fail at runtime. These types should use export = instead of export default. https://github.com/arethetypeswrong/arethetypeswrong.githubb.io/blob/main/docs/problems/FalseExportDefault.md

🐛 Import resolved to types through a conditional package.json export, but only after failing to resolve through an earlier condition. This behavior is a TypeScript bug (https://github.com/microsoft/TypeScript/issues/50762). It may misrepresent the runtime behavior of this import and should not be relied upon. https://github.com/arethetypeswrong/arethetypeswrong.github.io/blob/main/docs/problems/FallbackCondition.md

🎭 Import resolved to a CommonJS type declaration file, but an ESM JavaScript file. https://github.com/arethetypeswrong/arethetypeswrong.github.io/blob/main/docs/problems/FalseCJS.md
