    Class EmitterElement

    A subclass of HTMLElement which declares what events can be emitted by it at the type level. Thus, calling this.emit() with an undeclared event name will be a type error.

    It also offers proper type checking of the data provided to EmitterElement.emit using the types declared in HTMLElementEventMap.

    declare global {
        interface HTMLElementEventMap {
            "my-event": { name: string; count: number; }
        }
    }

    class MyElement extends EmitterElement {
        emits!: Emits<"my-event">;

        handleMyEvent() {
            this.emit("my-event", { name: "Joe", count: 1337 });
        }
    }
