Implement error handling that gracefully degrades when operations fail, uses consistent reporting patterns, and considers security implications. Always wrap potentially failing operations in try-catch blocks, provide meaningful fallback behavior, and follow established error reporting conventions.
Implement error handling that gracefully degrades when operations fail, uses consistent reporting patterns, and considers security implications. Always wrap potentially failing operations in try-catch blocks, provide meaningful fallback behavior, and follow established error reporting conventions.
Key principles:
Example implementation:
try {
sessionStorage.setItem(storageKey, JSON.stringify(data));
} catch (error) {
warning(
false,
`Failed to save data in sessionStorage, feature will not work properly. ${error}`
);
// Continue execution - don't let storage failure break the app
}
// Environment-aware error disclosure
error.stack = process.env.NODE_ENV === "development" ? val.stack : "";
// Proper error propagation with meaningful responses
if (res.status === 404) {
throw new ErrorResponseImpl(404, "Not Found", true);
}
This approach ensures applications remain functional even when individual operations fail, while maintaining appropriate security boundaries and consistent user experience.
