Quick Start Component

import React from 'react';
import {
  View,
  Text,
  StyleSheet,
  Pressable,
  Image,
} from 'react-native';
import Animated, {
  useSharedValue,
  useAnimatedStyle,
  withSpring,
} from 'react-native-reanimated';

interface ItemCardProps {
  title: string;
  subtitle: string;
  imageUrl: string;
  onPress: () => void;
}

const AnimatedPressable = Animated.createAnimatedComponent(Pressable);

export function ItemCard({ title, subtitle, imageUrl, onPress }: ItemCardProps) {
  const scale = useSharedValue(1);

  const animatedStyle = useAnimatedStyle(() => ({
    transform: [{ scale: scale.value }],
  }));

  return (
    <AnimatedPressable
      style={[styles.card, animatedStyle]}
      onPress={onPress}
      onPressIn={() => { scale.value = withSpring(0.97); }}
      onPressOut={() => { scale.value = withSpring(1); }}
    >
      <Image source={{ uri: imageUrl }} style={styles.image} />
      <View style={styles.content}>
        <Text style={styles.title} numberOfLines={1}>
          {title}
        </Text>
        <Text style={styles.subtitle} numberOfLines={2}>
          {subtitle}
        </Text>
      </View>
    </AnimatedPressable>
  );
}

const styles = StyleSheet.create({
  card: {
    backgroundColor: '#ffffff',
    borderRadius: 16,
    overflow: 'hidden',
    shadowColor: '#000',
    shadowOffset: { width: 0, height: 2 },
    shadowOpacity: 0.1,
    shadowRadius: 8,
    elevation: 4,
  },
  image: {
    width: '100%',
    height: 160,
    backgroundColor: '#f3f4f6',
  },
  content: {
    padding: 16,
    gap: 4,
  },
  title: {
    fontSize: 18,
    fontWeight: '600',
    color: '#1f2937',
  },
  subtitle: {
    fontSize: 14,
    color: '#6b7280',
    lineHeight: 20,
  },
});
