Enum in TypeScript

Question

I have a problem using an enum in Typescript.

export enum RegistrationStatusEnum {
        Pending,
        Rejected,
        Approved,
        InManagement,
    }

UserDTO.ts

import { RegistrationStatusEnum } from "../../Enums/RegistrationStatusEnum";

export class UserDTO {
  Name: string
  RegistrationStatus: RegistrationStatusEnum
}

OtherTS.ts

disableStatus(currentUser: UserDTO):boolean
    return currentUser.RegistrationStatus.Pending || currentUser.RegistrationStatus.Rejected || currentUser.RegistrationStatus.InManagement;
}

When I try to access Pending or other enum, I get an error The 'Pending' property does not exist in the 'RegistrationStatusEnum' type What is happening? Thx!

Answer 1

currentUser.RegistrationStatus is an enum value, it can be one of the enum members, but to check that you need to use === operator and compare with the specific field from the enum:

disableStatus(currentUser: UserDTO): boolean {
    return currentUser.RegistrationStatus === RegistrationStatusEnum.Pending 
        || currentUser.RegistrationStatus === RegistrationStatusEnum.Rejected 
        || currentUser.RegistrationStatus === RegistrationStatusEnum.InManagement;
}
