How to convert union type to enum in typescript?

Question

I want to covert union type to enum or like enum in typescript

It doesn't work out with my brain.

Thank you for reading my question.

type status = 'start' | 'loading' | 'stop';

class Loading {
    static staticStatus: status;
}
Loading.staticStatus.start; // i want to use.

or

type status = 'start' | 'loading' | 'stop';

enum statusEnum = ?????;

class Loading {
    static staticStatus = statusEnum;
}
Loading.staticStatus.start; // i want to use.

I'm sorry I didn't write my questions in detail.

const schema ={
 status: Joi.string()
        .required()
        .valid(
            'start',
            'loading',
            'stop',
        )
}

// type setStatusType =  'start' | 'loading' | 'stop' is like this
type setStatusType = PickType<Joi.extractType<typeof schema>, 'status'>; 

enum statusEnum = ?????;

class Loading {
    static staticStatus = statusEnum;

    public setLoading() {
    this.status = Loading.staticStatus.loading // I want to use this.
    }
}

so I want to covert union type to enum...

Not sure how you would get an enum from a Union but you can easily do the reverse if you need both.

enum Status {
 start,
 loading,
 stop
}

type StatusAsUnion = keyof typeof Status

Hopefully this was useful
