export interface MyEmitterEvents {
  '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
})

AbortOptions

import type { AbortOptions } from '@libp2p/interfaces'

Startable

Lifecycles for components

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

class MyStartable implements Startable {
  // .. implementation methods
}

const myStartable = new MyStartable()

isStartable(myStartable) // returns true
