🆕 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
