Answer
The exports field controls which files of a package are accessible, helping secure internal modules and define public APIs.
Quick Answer
The exports field in package.json defines your package's public API — which files are accessible when someone imports your package and from which paths. It lets you have multiple entry points (CJS, ESM, browser builds), block access to internal files, and provide conditional exports based on the environment (node vs browser). It replaces the old "main" field.
