find‑down is a tiny Node.js utility that searches for a file by walking **down** the directory tree from the current working directory (or a supplied start point) toward the filesystem root, returning the first match it encounters. It returns a Promise that resolves to the found path (or null) and supports searching for multiple candidate filenames. This library is aimed at JavaScript developers who need a simple, asynchronous way to locate configuration or resource files that may reside higher up in a project’s hierarchy.
