fd-lock is a tiny Node.js library that provides stateful file‑descriptor locking primitives for JavaScript applications. It lets developers create a lock object around an existing file descriptor, optionally wait for the lock to become available, and cleanly release it with `close()`. This package is aimed at server‑side JavaScript developers who need reliable cross‑process file locking (e.g., for singleton services, resource coordination, or safe file updates).
