How to create a custom Stencil component with the Ionic PWA Starter Kit

I just run the command:

$ npx create-stencil ionic-pwa

which created a vanilla Ionic 4 PWA with the following directory structure inside directory: src:

.
├── assets
│   └── icon
│       ├── favicon.ico
│       └── icon.png
├── components
│   ├── app-home
│   │   ├── app-home.css
│   │   ├── app-home.spec.ts
│   │   └── app-home.tsx
│   ├── app-profile
│   │   ├── app-profile.css
│   │   ├── app-profile.spec.ts
│   │   └── app-profile.tsx
│   └── my-app
│       ├── my-app.css
│       ├── my-app.spec.ts
│       └── my-app.tsx
├── components.d.ts
├── global
│   ├── app.css
│   └── app.ts
├── helpers
│   └── utils.ts
├── index.html
├── manifest.json
└── sw.js

Then I want to create a custom component with html tag: comp-workspace and file name: comp-workspace.js (or something similar) that I can insert on any vanilla HTML/Javascript page without using any Javascript framework.

There are some things to take into consideration here:

  1. component: comp-workspace can include the following components: { comp-gallery, comp-artboard, comp-text-editor, comp-layer-stack }.

  2. all above components can include standard Ionic components.

Please, take a look to the following diagram:

enter image description here

Here is the directory structure after adding my custom component: comp-workspace and its dependencies.

.
├── assets
│   └── icon
│       ├── favicon.ico
│       └── icon.png
├── components
│   ├── app-home
│   │   ├── app-home.css
│   │   ├── app-home.spec.ts
│   │   └── app-home.tsx
│   ├── app-profile
│   │   ├── app-profile.css
│   │   ├── app-profile.spec.ts
│   │   └── app-profile.tsx
│   ├── comp-workspace
│   │   ├── comp-workspace.css
│   │   ├── comp-workspace.spec.ts
│   │   └── comp-workspace.tsx
│   ├── comp-gallery
│   │   ├── comp-gallery.css
│   │   ├── comp-gallery.spec.ts
│   │   └── comp-gallery.tsx
│   ├── comp-artboard
│   │   ├── comp-artboard.css
│   │   ├── comp-artboard.spec.ts
│   │   └── comp-artboard.tsx
│   ├── comp-text-editor
│   │   ├── comp-text-editor.css
│   │   ├── comp-text-editor.spec.ts
│   │   └── comp-text-editor.tsx
│   ├── comp-layer-stack
│   │   ├── comp-layer-stack.css
│   │   ├── comp-layer-stack.spec.ts
│   │   └── comp-layer-stack.tsx
│   └── my-app
│       ├── my-app.css
│       ├── my-app.spec.ts
│       └── my-app.tsx
├── components.d.ts
├── global
│   ├── app.css
│   └── app.ts
├── helpers
│   └── utils.ts
├── index.html
├── manifest.json
└── sw.js

Then, I want to use my custom component in a way similar to:

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>Title of the document</title>
<script src="..."></script>
<script src="https://my.repository.com/components/comp-workspace.js"></script>
</head>

<body>
	<comp-workspace attr1="..." attr2="..." attr3="..." ...></comp-workspace>
</body>

</html>

If I run the build command on the console I get the following output:

$ npm run build

> @ionic/pwa-toolkit@0.0.1 build D:\stencil-lab

I also get a new directory: www with the following content:

6 directories, 832 files

but as you can see, I don’t get an actual javascript bundle file I can use to insert my custom component on any vanilla HTML/Javascript page.

My question is: how do I build just my custom component from inside this Ionic 4 PWA app?

Thanks!
