# Package Public API

> A new-architecture package (shared/, domain/, features/) exposes its API through barrels that contain nothing but `export *`, and keeps its private code in an internals location. Read this when creating a package under shared/, domain/ or features/, when editing any `index.*` file, or when a `lint:structure` check fails.
