find-package-json offers a robust and efficient way to locate package.json files, traversing upwards from a given starting directory. It provides a simple, promise-based API to search for the nearest package.json, stopping at the root directory or when a file is found. Ideal for tools and libraries needing to determine project root or access package metadata, it ensures consistent and reliable file location across diverse environments and directory structures. Think of it as smarter require.resolve('package.json').
