I have an enum:

export enum ApiMessages {

Answer 1

For those who come looking as I did, this works for me.

NOTE: This is only valid if you know that your string value is a valid 'key'.

enum Fruit {
    Apple = 'apple',
    Bananna = 'bananna'
}

const str: string = 'apple';

const fruit = str as Fruit;

if (fruit === Fruit.Apple)
    console.log("It's an apple");

if (fruit === Fruit.Bananna)
    console.log("It's a bananna");
