Class static side 'typeof Emitter' incorrectly extends base class static side 'typeof EventEmitter'

Describe the Bug

@moltar thanks for bringing this up.

Given that this is a community repo with established processes, we’ll need to discuss it. But I think it is a good suggestion. I’ve opened an issue to track this https://github.com/cloudevents/sdk-javascript/issues/388.

I’m having this issue as well in version 4.0.0.

I did some testing and it looks like it’s caused by the version of @types/node being used. The typescript example in this repository is using @types/node@8.9.0 which is 3 years old. I’m currently using @types/node@14.14.10 and seeing the issue, and @moltar 's example is using 14.14 as well.

I downgraded to cloudevents@3.2.0 for now and it’s compiling for me with the latest @types/node.
