The **limit‑spawn** module is a tiny Node.js utility that wraps a child process created with `child_process.spawn` and automatically terminates it once a configurable amount of output data (in bytes) has been sent. It also emits a `max-limit-exceeded` event so callers can react when the soft limit is reached. This package is aimed at developers who need to enforce output size caps on spawned processes—e.g., to prevent runaway logging or resource‑exhaustion in CLI tools or server‑side scripts.
