Class constructor Positions cannot be invoked without 'new'

[yosa]

I am trying to create an instance of one class that extends from another.

Within the constructor of the daughter class I execute the super () method to execute the constructor of the parent class.

An example:

import StoreService from 'core / services / StoreService'
import Store from 'src / store / base / positions'

class Positions extends StoreService {
   constructor () {
     super (Store, 'basePositions')
   }
}

export default new Positions ()

This class to extend and make use of it is the one that throws me the error:

Class constructor Positions cannot be invoked without ‘new’.

Any suggestions? I think the problem is related to babel but I can’t find an applicable solution to the quasar project.

Hello
Check the links but I continue with the detail. The problem is caused by a simple class and I am not using typescript. I will continue investigating, thank you very much @Hawkeye64

maybe try:

const pos = new Positions()
export default pos

also, remove the space here: Positions () and try Positions() to see if that makes a difference

export default class ... doesn’t work?
