basic‑subleveler is a tiny Node.js helper that streamlines setting up one‑level‑deep sublevels on a LevelDB instance using the `level-sublevel` package. It creates named sublevels, exposes the database’s `close` method, and adds a convenience `readAllValuesFromSublevel` function, making it easier for developers who need simple, organized LevelDB storage without writing repetitive boilerplate.
