This package provides TypeScript definitions for the npm-package-arg library. npm-package-arg parses npm package argument strings (like foo, github:foo/bar, or file:../baz) into structured objects, useful for understanding and manipulating package dependencies. These definitions enhance TypeScript projects by providing static typing for inputs and outputs, improving code maintainability and reducing runtime errors when working with this utility. They enable more robust and predictable handling of npm package specifications within TypeScript-based tooling.
