Angular 4 export enum type from library/dependency

Question

I want to make a library to use in my Angular 4 applications, and for some business I will do on it I have an enum that the applications will need to use later. Problem is, I declare the enum like this in my-enum.ts:

export enum MyEnum {
    value1 = 1,
    value2 = 2,
    value3 = 3
}

But then, I can't seem to import it from my app when I do the following:

import { MyEnum } from 'my-library';

How should I proceed to have this correctly?

Do you have an index.ts file in the root location of the library? — Bogdan Bogdanov

you have to export also the enum as well or you will have to add the relative path to the enum in the import statement like import { MyEnum } from '../node_modules/my-library/myenum'; — Bogdan Bogdanov

If you are writing Angular libraries, you have to export enums with the keyword const

export const enum <ENUM_NAME>

I had the same issue, but I simply forgot to build my library before trying to use the exported enum (ng build --prod my-library).
