How do I properly include enums and interfaces in the project?

Hi folks, I’m trying to build a library that is dependent on another public npm package of mine.

I am using the latest @angular/cli that includes library generation.

In Project A, when built I have a enum/interfaces file that is in dist/a/lib/types.d.ts that I want users to be able to freely import from the package.

Looks like this:

export interface ScrollIndex {
    start?: number;
    end?: number;
}

export interface ScrollEvent {
    type: ScrollType;
    index?: ScrollIndex;
    scrollLeft?: number;
}

export enum ScrollType {
    Horizontal,
    Vertical
}

In another larger Project B, I have Project A listed as a dependency.

{
  "name": "@.../ProjectB",
   ...
  "dependencies": {
    "@../ProjectA": "0.0.6",
  }
}

Here’s where I may be confused or packing the project incorrectly.

Inside Project B, I am referencing Project A’s types using: import { ScrollIndex, ScrollEvent, ScrollType } from '@.../ProjectA/lib/types';

I would like to be able to import them directly from @.../ProjectA if possible.

Secondary to that issue, I then get an error when serving the project that it cannot resolve the types.

ERROR in ./node_modules/@ngx-easy/grid/esm5/ngx-easy-grid.js
Module not found: Error: Can't resolve '@ngx-easy/virtual-scroll/lib/types' in 'C:\Users\Tyler\Documents\GitHub\@ngx-easy\node_modules\@ngx-easy\grid\esm5'

When I view that esm5 generated file… I see only this is imported at the top… which is the only enum, coincidence?

import { ScrollType } from '@ngx-easy/virtual-scroll/lib/types';

If I remove that line from \node_modules\@ngx-easy\grid\esm5 then I no longer get console errors.

Any tips or feedback is much appreciated!

I was getting the same error and adding const to my enum made the difference.

export const enum Statuses{
   Active = 'Active', 
   Deactivated = 'Deactivated',
   Undefined = ''
}

Hey thanks for the reply @alan-agius4

From public_api.ts

export * from './lib/types';

I’ve have successfully been able to import…

import { ScrollIndex, ScrollEvent, ScrollType } from '@ngx-easy/virtual-scroll';

…and reference them in the typescript without issue, I’m not sure what I was doing before but the interfaces and enums appear to be working fine.
