Node‑EventYoshi is a lightweight utility that aggregates multiple Node.js EventEmitters into a single, unified emitter. It lets you add or remove child emitters at runtime while automatically forwarding listeners (including `once` and proxying arbitrary methods) and preserving the source of each event, making it easier to manage complex event flows without manually wiring each emitter. The library is aimed at JavaScript developers who need to coordinate many emitters—such as in server‑side applications, streams, or modular components—while keeping a clean, single‑point interface for event handling.
