Use object literal as TypeScript enum values

Question

I have an enum:

export enum PizzaSize {
  SMALL =  0,
  MEDIUM = 1,
  LARGE = 2
}

But here I\'d like t

You can use a typed const to achieve this:

export const PizzaSize: {
    [key: string]: { key: string, value: string };
} = {
    SMALL: { key: 'key', value: 'value' }
};

Optionally you can extract the type information to separate interface declarations:

interface PizzaSizeEnumInstance {
    key: string;
    value: string;
}

interface PizzaSizeEnum {
    [key: string]: PizzaSizeEnumInstance;
}

export const PizzaSize: PizzaSizeEnum = {
    SMALL: { key: 'key', value: 'value' }
};
