Angular

Angular apps can use either Cordova or Capacitor to build native mobile apps. For Angular, the import path should end with /ngx.

import { Platform } from "@ionic/angular";
 import { Purchases } from "@ionic-native/purchases/ngx";

 constructor(public platform: Platform, private purchases: Purchases) {
     platform.ready().then(() => {
         this.purchases.setDebugLogsEnabled(true); // Enable to get debug logs
         this.purchases.setup("my_api_key", "my_app_user_id");
     }
 }

React

Import the plugin object then use its static methods:

import { Purchases } from '@ionic-native/purchases';

const Tab1: React.FC = () => {
  Purchases.setDebugLogsEnabled(true);
  Purchases.setup("my_api_key", "my_app_user_id");
  return (
    <IonPage>
      <IonHeader>
        <IonToolbar>
          <IonTitle>Tab 1</IonTitle>
        </IonToolbar>
      </IonHeader>
      <IonContent>
        <IonButton onClick={openScanner}>Scan barcode</IonButton>
      </IonContent>
    </IonPage>
  );
};
