🆕 Expert Remediation Examples

Before vs. After: Automatic Code Fixing

❌ Before (Problematic Code):

const MyComponent = () => {
  const apiKey = "sk-1234567890abcdef"; // Hardcoded secret
  const [data, setData] = useState([]);
  
  useEffect(() => {
    console.log("API Key:", apiKey); // Sensitive logging
    fetch('http://api.example.com/data') // HTTP instead of HTTPS
      .then(response => response.json())
      .then(data => setData(data));
      
    const interval = setInterval(() => { // Memory leak
      console.log('Polling...');
    }, 1000);
  }, []);

  return (
    <ScrollView>
      {data.map(item => ( // Performance issue
        <Text key={item.id} style={{color: 'red'}}>{item.name}</Text>
      ))}
    </ScrollView>
  );
};

✅ After (Expert Remediation):

interface Props {
  children?: React.ReactNode;
  onPress?: () => void;
}

const MyComponent: React.FC<Props> = () => {
  // TODO: Add API_KEY to your environment variables
  const apiKey = process.env.API_KEY || Config.API_KEY;
  const [data, setData] = useState([]);
  
  useEffect(() => {
    // Removed sensitive logging for security
    // console.log('[REDACTED - contains sensitive data]');
    
    // Upgraded to HTTPS for security
    fetch('https://api.example.com/data')
      .then(response => response.json())
      .then(data => setData(data));
      
    const interval = setInterval(() => {
      console.log('Polling...');
    }, 1000);
    
    // Cleanup intervals to prevent memory leaks
    return () => {
      clearInterval(interval);
    };
  }, []);

  return (
    <FlatList
      data={data}
      keyExtractor={(item, index) => item.id?.toString() || index.toString()}
      renderItem={({ item }) => (
        <Text style={styles.itemText}>{item.name}</Text>
      )}
    />
  );
};

const styles = StyleSheet.create({
  itemText: {
    color: 'red'
  }
});

export default React.memo(MyComponent);

🎯 What Got Fixed Automatically:

✅ Security: Hardcoded API key → Environment variable
✅ Security: Sensitive logging → Sanitized
✅ Security: HTTP → HTTPS upgrade
✅ Performance: ScrollView + map → FlatList with keyExtractor
✅ Memory: Added interval cleanup to prevent leaks
✅ Best Practices: Inline styles → StyleSheet.create
✅ Type Safety: Added TypeScript interface
✅ Performance: Wrapped with React.memo
