Advantages over standard node events library?

[benjiwheeler]

Colleagues are asking whether to use pubsub-js or https://github.com/Gozala/events for a project.

I know pubsub-js is more extensive, but could the README clarify what pubsub-js can do that events can't? I understand that to use events similarly, you'd need to create a singleton instance, and from various places in your code, call the subscription and publishing/emitting functions on that instance.

If you chose to use EventEmitter or similar as a singleton, you've basically created an implementation of publish/subscribe, very similar to PubSubJS. I think that both options are quite stable, so either would be a decent choice.

If you chose to go with EventEmitter, then I'd recommend creating the singleton in a file that can then be imported where needed, so you don't have to explicitly pass the singleton around. That's just a matter of convenience really.

There might be minor difference in features that make one solution more appealing than the other. Maybe one has a feature/method that you need, and the other doesn't.

If you feel like it, then a PR comparing PubSubJS with other solutions in a table, would be a nice addition to the README.
