I defined a service package for my angular app, where it has string enum definitions:

export enum CloudTypeEnum {
   AZURE =  'AZURE',
   AMAZON = 'AMAZON',
   GOOGLE = 'GOOGLE',
}

In the tsconfig.json, I define the package path, where it exports the string enum:

"paths": {
            "@cloud-services/*": ["packages/service/*"],
}

When trying to use it in the angular service

import {CloudTypeEnum} from '@cloud-service';

isAzureCloud(type: CloudTypeEnum):boolean {
   return type == CloudTypeEnum.AZURE;
}

I found that the CloudTypeEnum is not a object but a module in the chrome inspector.
While the enum defined in the service is a object. So I am not sure why typescript compile my enum to module, which may lead if check always return false.
