PWA Elements
Capacitor のプラグインの中には、CameraやToastのように、ネイティブで動作していないときにウェブベースの UI を利用できるものがあります。例えば、Camera.getPhoto()を呼び出すと、ウェブ上で動作しているときに、レスポンシブな写真撮影エクスペリエンスをロードします:
この UI は、Web コンポーネントを使って実装されています。Shadow DOM の魔法により、これらのコンポーネントは、あなた自身の UI と あなた自身の UI と衝突しないようにします。
Installation
To enable these controls, you must add @ionic/pwa-elements to your app.
A typical installation involves importing the package and registering the elements, or adding a script tag to the <head> of the index.html for your app:
Importing PWA Elements
npm install @ionic/pwa-elements
Then, depending on your framework of choice, import the element loader and call it at the correct time:
React
index.tsx or index.js:
import { defineCustomElements } from '@ionic/pwa-elements/loader';
ReactDOM.render(<App />, document.getElementById('root'));
// Call the element loader after the app has been rendered the first time
defineCustomElements(window);
Angular
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 { defineCustomElements } from '@ionic/pwa-elements/loader';
if (environment.production) {
enableProdMode();
}
platformBrowserDynamic()
.bootstrapModule(AppModule)
.catch(err => console.log(err));
// Call the element loader after the platform has been bootstrapped
defineCustomElements(window);
Including through script tag
PWA Elements can be included through a script tag in your index.html. However, keep in mind this will not work for offline scenarios:
<script
type="module"
src="https://unpkg.com/@ionic/pwa-elements@latest/dist/ionicpwaelements/ionicpwaelements.esm.js"
></script>
<script
nomodule
src="https://unpkg.com/@ionic/pwa-elements@latest/dist/ionicpwaelements/ionicpwaelements.js"
></script>
