How to add an enum in class in Typescript

Question

I define a model class and I would like to add an enum label like:

export class User {
    userID: number;
    nom: string;
    prenom: string;
    dateCretation: Date;
    statut: enum {
        Value1,
        Value2
    };
}

I got a mark error in enum:

[ts] Type expected.

How can I resolve it ?

Answer 1

You will need to declare the enum beforehand, and then type it to the properties that you want to have of that type:

export enum Values {
  Value1,
  Value2
}

export class User {
  userID: number;
  nom: string;
  prenom: string;
  dateCretation: Date;
  statut: Values
}

Another alternative is that if you know for sure that statut can only strictly take in two values, of which they are type of, say, string, then you can do like the following:

export class User {
  userID: number;
  nom: string;
  prenom: string;
  dateCretation: Date;
  statut: "Value1" | "Value2"
}
