Basic Ionic App Structure

                        
// app.component.ts (Angular)
import { Component } from '@angular/core';

@Component({
  selector: 'app-home',
  templateUrl: 'home.page',
  styleUrls: ['home.page.scss'],
})
export class HomePage {
  constructor() {}
  
  showAlert() {
    // Handle button click
    console.log('Button clicked!');
  }
}

// home.page
<ion-header [translucent]="true">
  <ion-toolbar>
    <ion-title>My Ionic App</ion-title>
  </ion-toolbar>
</ion-header>

<ion-content [fullscreen]="true">
  <ion-card>
    <ion-card-header>
      <ion-card-title>Welcome to Ionic</ion-card-title>
    </ion-card-header>
    <ion-card-content>
      <p>Build amazing mobile apps with web technologies!</p>
      <ion-button expand="block" (click)="showAlert()">
        Click Me
      </ion-button>
    </ion-card-content>

  IonToolbar,
  IonCard,
  IonCardContent,
  IonCardHeader,
  IonCardTitle,
  IonButton
} from '@ionic/react';

const Home: React.FC = () => {
  const handleClick = () => {
    console.log('Button clicked!');
  };

  return (
    <IonPage>
      <IonHeader>
        <IonToolbar>
          <IonTitle>My Ionic React App</IonTitle>
        </IonToolbar>
      </IonHeader>
      <IonContent fullscreen>
        <IonCard>
          <IonCardHeader>
            <IonCardTitle>Welcome to Ionic React</IonCardTitle>
          </IonCardHeader>
          <IonCardContent>
            <p>Build cross-platform apps with React and Ionic!</p>
            <IonButton expand="block" onClick={handleClick}>
              Click Me
            </IonButton>
          </IonCardContent>
        </IonCard>
      </IonContent>
