View source on GitHubError Handling Rules
No Silent Error Suppression
CRITICAL: Never use empty catch blocks or catch blocks that silently hide errors.
❌ FORBIDDEN:
try {
// code
} catch (error) {
// Empty - silently hides error
}
try {
// code
} catch (error) {
return false; // Silently hides error
}
try {
// code
} catch (_error) {
// Underscore prefix doesn't make it acceptable
}
✅ REQUIRED:
try {
// code
} catch (error) {
// Check for expected error types
if (error instanceof TypeError) {
return false;
}
// Re-throw unexpected errors
throw error;
}
try {
// code
} catch (error) {
// Log and handle appropriately
logger.error('Operation failed', error);
throw new Error('Specific error message', { cause: error });
}
Rules:
- Always handle errors explicitly - Check error type and handle expected errors only
- Re-throw unexpected errors - Never silently suppress errors you don't understand
- No bare catch blocks - Every catch must have meaningful error handling
- No underscore-prefixed unused errors - If you catch it, handle it properly
- Log critical errors - Use proper logging for debugging and monitoring
Exceptions:
Only acceptable when:
- Error type is explicitly checked (e.g.,
error instanceof TypeError) - Unexpected errors are re-thrown
- Error is logged with context before returning fallback value
