  'some-event': CustomEvent<number>;
}

class MyEmitter extends EventEmitter<MyEmitterEvents> {

}

// later
const myEmitter = new MyEmitter()
myEmitter.addEventListener('some-event', (evt) => {
  const num = evt.detail // <-- inferred as number
})

Lifecycles for components

import { start, stop, isStartable } from '@libp2p/interfaces/startable'
import type { Startable } from '@libp2p/interfaces/startable'
