Issue with subclasses about tiny-typed-emitter HOT 2 OPEN

Scratch my previous.
I tested it in my module, published the module, and everything worked okay with 2 files.
Beyond that, it spews the events into other types. It was probably doing that with 2 files, but I didn't catch it.

So, you could use what I stated previously, however you will end up with code bleed all over.

I have another solution that I've been using for a few months, but it's hackish.
I'll post it here when I get a minute. Basically you'll need to create your own on and once overrides for the emitter with new generic type defs. From what I recall I also had to wrap another class that extended EventEmitter.

I finally worked around this issue by following how FeathersJS extends its ServiceTypes interface;
I failed to realize that we can extend interfaces from different files using the module syntax, declare module './declaration-ts-file', within the file of the class you want to extend events.

To make this work, follow these steps:

1. Create a TS file to store the base events (i.e. ServiceEvents.ts)
2. In that base events file add your events interface (i.e. export interface ServiceEvents { someEvent: () => void; })
3. In your base class file, extends TypedEmitter<ServiceEvents> as you normally would
4. In your child class file, extend the base class
5. In that same child class file, declare a module with the filename of the base events interface as follows...

declare module './ServiceEvents' { interface ServiceEvents { newEvent: (data: string) => void; } }

You will now have a strongly typed "newEvent" for the child class and observe that other child classes will not have that new event, as expected.

Notice that I created the interfaces and classes in separate files as to eliminate any possibility for a collision with another declare module './ServiceEvents' declaration.

Enjoy.
