`async-folder-walker` provides an asynchronous, recursive iterator that yields every file and sub‑directory within one or more root paths, supporting depth limits, path‑ and stat‑based filtering, depth control, and optional ignore patterns. It’s ideal for Node.js developers who need a flexible, stream‑free way to traverse complex folder hierarchies—e.g., for indexing, caching, or processing large directory trees without blocking the event loop.
