Using ng-packagr to build Ionic component library - ionic-framework

Question

I have a huge need to build a monorepo for my organization's Ionic assets. We produce a suite of applications, and like to share as much as possible in order to reduce our time-to-market. I found ng-packagr a week ago and think it's much better than the previous methods I've been using.
In any case, I'm developing a proof-of-concept, and can't get the ionic-angular library compiling. ngc breaks, and I'm not sure how to go about fixing it.
First, let me share my package.json and see if I'm on the right track here:
{
"name": "ionic-packagr-test",
"version": "0.0.1",

"homepage": "http://ionicframework.com/",

},

},

}
I have a pretty vanilla component I'm trying to build, just using a shell Ionic blank template and exporting app.module.ts in my public_api.ts file.
When I run the packager, I get the following error:
BUILD ERROR
node_modules/ionic-angular/components/picker/picker-component.d.ts.PickerCmp.html(13,71): : Expected 0 arguments, but got 1.

Could it be possible that I'm using the wrong version of ng-packagr?
Thanks in advance.

Found a tutorial after days of looking. Will not copy/paste the article -- don't want to plagiarize or suppress traffic from his site.
Essentially, all dependencies should become devDependencies. If your package uses any devDependencies copy them as peerDependencies.
