Common Patterns to Flag
Security
// BAD: SQL injection
const query = `SELECT * FROM users WHERE id = ${userId}`;
// GOOD: Parameterized query
const query = 'SELECT * FROM users WHERE id = $1';
await db.query(query, [userId]);
Performance
// BAD: N+1 query
users.forEach(async user => {
const posts = await getPosts(user.id);
});
// GOOD: Batch query
const userIds = users.map(u => u.id);
const posts = await getPostsForUsers(userIds);
Error Handling
// BAD: Swallowing errors
try {
await riskyOperation();
} catch (e) {}
// GOOD: Handle or propagate
try {
await riskyOperation();
} catch (e) {
logger.error('Operation failed', { error: e });
throw new AppError('Operation failed', { cause: e });
}
