Scale and Angular

Angular works well with custom elements, but has some minor limitations.

To work around these problems we provide custom element wrappers for better developer experience.

Please note that you will need to install both, the telekom/scale-components-neutral as well as the @telekom/scale-components-angular-neutral packages.

Once you have installed both packages and defined the custom elements, Scale components behave mostly the way you would expect a Angular component to behave!

main.ts

import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';

import { AppModule } from './app/app.module';
import { environment } from './environments/environment';

import { applyPolyfills, defineCustomElements } from '@telekom/scale-components-neutral/loader';

if (environment.production) {
  enableProdMode();
}

platformBrowserDynamic().bootstrapModule(AppModule)
  .catch(err => console.error(err));

applyPolyfills().then(() => {
  defineCustomElements(window);
});

src/app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { ComponentLibraryModule } from '@telekom/scale-components-angular-neutral';
import { NgModule, CUSTOM_ELEMENTS_SCHEMA } from '@angular/core';

import { AppComponent } from './app.component';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    FormsModule,
    BrowserModule,
    ComponentLibraryModule
  ],
  providers: [],
  bootstrap: [AppComponent],
  schemas: [CUSTOM_ELEMENTS_SCHEMA]
})
export class AppModule { }

src/app.component.html

<div>
    <scale-button>Click!</scale-button>
</div>

Events in Angular

In order to prevent collisions with standard events and compatibility with other libraries and frameworks, some components of Scale are using custom event names. You can find documentation for the custom events on the respective component pages in the docs section.

Events in Angular are prefixed with: scale-{event-name}
