Expected behavior:

ng-packagr should create package successfully like it does for angular project without ngrx.

Minimal reproduction of the problem with instructions:

Please download the ngrx-with-ng-packgr.zip
zip project and then run

npm install
ng-packagr

Version of affected browser(s),operating system(s), npm, node and ngrx:

Browser: Chrome, OS : Windows 2010 , npm 5.6.0, node v8.9.4, ngrx 5.0.1, typescript: ~2.5.3

Other information:

As per microsoft/TypeScript#9944, I also upgraded my typescript version to typescript@next still i am getting the issue.
Please let me know where I am missing something. Also is their any other option to create a package for ngrx project which I can use as npm module. I also created one more issue in ng-packagr not sure where this bug is ng-packagr/ng-packagr#542 It seems that even though we are exporting the MemoizedSelector it is not working properly #57

Hi I created an issue in ng-packagr github ng-packagr/ng-packagr#542
It seems it is not ngrx issue therefore i am closing this issue. I solved this issue by the recommendation of Danny Blue . Here is the working solution, basically we have to explicitly export the types.
If you are using @ngrx/entity then please make sure you import their types and use them in order to compile using ng-packagr.

import { MemoizedSelector } from '@ngrx/store/src/selector';
import { Dictionary, EntitySelectors } from '@ngrx/entity/src/models';
const entityFns = fromProductsAdapter.getSelectors(getProductEntitiesState);
export const {
    selectIds: getProductIds,
    selectAll: getAllProducts,
    selectTotal: getTotalProducts,
  } = entityFns;
export const getProductState: MemoizedSelector<any, any> = createFeatureSelector<any('products');
export const {selectEntities: getProductEntities}: EntitySelectors<Product, any> = entityFns;
