Exporting an angular component as a module

I have successfully created a widget using Angular elements that works well in HTML. However, I am unsure of how to export it as a module for use in other Angular, React, Vue web applications. I want to be able to import

import { acmaModule } from package-name

instead of

const acmaModule = require('widge.js')

.

In my Angular code:

export class AppModule {
  initWidget(options: any){
    console.log('options received', options)
  }

  constructor(private injector: Injector) {
    // Expose Window function
    (<any>window).acmeWidget = { initWidget: this.initWidget  };

     // Survey Widget
    const surveyComp: any = createCustomElement(SurveyComponent, { injector: this.injector });
    customElements.define('acme-survey', surveyComp);
  }

  ngDoBootstrap() {}
}

And in the HTML file:

<html>
....
<script src="../survey-widget.js">
<script>
 acmeWidget.initWidget({
  test: "Hello world"
 })
</script>
....
</html>

javascript angular typescript

To simplify the process of packaging modules for external references, you can create an export file and specify the modules you want to include in it.

For instance, you can create a file named export.ts within the src directory. Then, populate the file with something similar to the following code snippet, assuming that your main AppModule is located at src\AppModule.ts:

//content of export.ts
export * from './AppModule';
...

In your ng-package.json configuration file, make sure to designate export.ts as the entry file. This can be achieved by including the following section:

//content of ng-package.json
{
  "$schema": "../../node_modules/ng-packagr/ng-package.schema.json",
  "dest": "../../dist/<your built package name>",
  "lib": {
    "entryFile": "src/export.ts"
  }
}

Once you have built your project, you can publish the artifact using the command npm publish. This will allow others to install and import your packaged modules via npm. If your project is named test-project, the process would look something like this:

ng build test-project --prod

# after build is done:
cd dist/test-project
npm publish
