get-package-info is a Node.js utility that searches for specified properties in package.json files, starting from a given directory and moving up through parent directories until all properties are found. It's designed for developers who need to access package.json data from parent directories, such as when building tools that need to discover project configuration from nested directories. The library returns a promise with the found values and their sources, making it useful for CLI tools, build systems, or any application that needs to traverse package.json hierarchies.
