The code I am working with is structured like this:
import * as events from 'events' // Utilizing Node.js events module
// My custom implementation of EventEmitter with enhanced typing
interface IEventEmitter<EventTypes> { /* ... */ }
// Disabling eslint rule to avoid explicit function return type declaration
export function EventEmitter<EventTypes>() {
// Merging the IEventEmitter interface and EventEmitter to create a unified, typed structure.
// Is there a more optimal approach?
return class NewEventEmitter
extends ((events.EventEmitter as unknown) as IEventEmitter<EventTypes>)
implements IEventEmitter<EventTypes> {}
}
In the above snippet, I have disabled an eslint rule to prevent errors related to return type specification, allowing it to be inferred.
However, the question arises - how should that return type be written?
EDIT: Here's a helpful playground example demonstrating @KarolMajewski's response in action. If encountering the error "Cannot find name 'NewEventEmitter'. Did you mean 'NodeEventEmitter'?", ensure the class assignment to a local variable.
EDIT 2: Affirmation that @KarolMajewski's explanation functions correctly, emphasizing the necessity of assigning the class to a local variable for effective implementation. Refer to the playground example for further details.
