eslint-plugin-import-access

ESLint plugin (v3.1.0) and TypeScript Language Service Plugin that enforces package-private imports via @package JSDoc annotations. The plugin restricts importing variables marked as @package from outside the same directory, providing a directory-level encapsulation layer beyond file-level exports. It requires TypeScript 5.0+, Node.js 20+, and @typescript-eslint/parser 8+. Key differentiators: supports both flat config and eslintrc, offers a language service plugin to prevent auto-completion of non-importable symbols, and is actively maintained with frequent releases.
