Thanks for the PR @norato! Isn't this pretty much a required step when adding @ngrx/data? I don't think it needs to be behind a flag.

Hello, @brandonroberts.
The entity-config is a required configuration to @ngrx/data works, as at the documentation we need to declare it to include in the store.

The ng-add only includes the EntityDataModule or EntityDataModuleWithouEffects at AppModule, but do not declare the entityConfig.

As the config is required I would make this the default and not provide a flag for it, as @brandonroberts mentioned.

This LGTM.
Can you confirm that what this schematic is doing is correct @wardbell ?

It will create an empty config file:

import { EntityMetadataMap, EntityDataModuleConfig } from '@ngrx/data';

const entityMetadata: EntityMetadataMap = {};

const pluralNames = {  };

export const entityConfig: EntityDataModuleConfig = {
  entityMetadata,
  pluralNames
};

And it will import, and pass is to the DataModule:

EntityDataModule.forRoot(entityConfig)
