The **throw‑max‑listeners‑error** package monkey‑patches Node’s built‑in `EventEmitter` so that any emitter that exceeds its `maxListeners` limit throws an exception instead of just emitting a warning. It’s intended for developers—especially test suites—to catch potential memory‑leak bugs early by turning the default “possible memory leak” warning into a hard error. Install it with npm and simply `require('throw-max-listeners-error')` to enable the behavior across your whole application.
