Use when designing error handling, setting up logging, implementing retries, adding error tracking, or when asked about error boundaries, log aggregation, alerting, or resilience patterns.\n---\n\n# Error Handling & Observability\n\n### When to Load\n\n- **Trigger**: Try/catch patterns, retry logic, error responses, circuit breakers, structured logging\n- **Skip**: No error handling or observability involved in the current task\n\n## Error Handling Workflow\n\nCopy this checklist and track progress:\n\n```\nError Handling Progress:\n- [ ] Step 1: Define error taxonomy (categories and severity)\n- [ ] Step 2: Implement error handling by layer\n- [ ] Step 3: Set up structured logging\n- [ ] Step 4: Add retry and circuit breaker patterns\n- [ ] Step 5: Configure error tracking service\n- [ ] Step 6: Define user-facing error messages\n- [ ] Step 7: Validate against anti-patterns checklist\n```\n\n## Error Handling Patterns by Language\n\n### JavaScript / TypeScript\n\n```typescript\n// Custom error hierarchy\nclass AppError extends Error {\n constructor(\n message: string,\n public statusCode: number = 500,\n public code: string = \"INTERNAL_ERROR\",\n public isOperational: boolean = true,\n ) {\n super(message);\n this.name = this.constructor.name;\n }\n}\nclass NotFoundError extends AppError {\n constructor(resource: string, id: string) {\n super(`${resource} with id ${id} not found`, 404, \"NOT_FOUND\");\n }\n}\nclass ValidationError extends AppError {\n constructor(public errors: Record) {\n super(\"Validation failed\", 400, \"VALIDATION_ERROR\");\n }\n}\n\n// WRONG: Swallowing errors silently\ntry {\n await saveUser(data);\n} catch (e) {\n // nothing here -- bug hides forever\n}\n\n// WRONG: Catching and re-throwing without context\ntry {\n await saveUser(data);\n} catch (e) {\n throw e; // pointless try/catch\n}\n\n// CORRECT: Add context, handle or propagate\ntry {\n await saveUser(data);\n} catch (error) {\n if (error instanceof ValidationError) {\n return res.status(400).json({ errors: error.errors });\n }\n logger.error(\"Failed to save user\", { error, userId: data.id });\n throw new AppError(\"Unable to save user\", 500, \"USER_SAVE_FAILED\");\n}\n```\n\n### Express Global Error Handler\n\n```typescript\n// Centralized error handler middleware (must have 4 params)\napp.use((err: Error, req: Request, res: Response, next: NextFunction) => {\n if (err instanceof AppError) {\n logger.warn(\"Operational error\", {\n code: err.code,\n statusCode: err.statusCode,\n path: req.path,\n });\n return res.status(err.statusCode).json({\n error: { code: err.code, message: err.message },\n });\n }\n\n // Unexpected errors -- these are bugs\n logger.error(\"Unexpected error\", {\n error: err.message,\n stack: err.stack,\n path: req.path,\n });\n res.status(500).json({\n error: { code: \"INTERNAL_ERROR\", message: \"An unexpected error occurred\" },\n });\n});\n```\n\n### Python\n\n```python\n# Custom exception hierarchy\nclass AppError(Exception):\n def __init__(self, message: str, code: str = \"INTERNAL_ERROR\", status: int = 500):\n self.message = message\n self.code = code\n self.status = status\n super().__init__(message)\n\nclass NotFoundError(AppError):\n def __init__(self, resource: str, id: str):\n super().__init__(f\"{resource} {id} not found\", \"NOT_FOUND\", 404)\n\nclass ValidationError(AppError):\n def __init__(self, errors: dict[str, list[str]]):\n self.errors = errors\n super().__init__(\"Validation failed\", \"VALIDATION_ERROR\", 400)\n\n# WRONG: Bare except\ntry:\n result = process(data)\nexcept: # catches SystemExit, KeyboardInterrupt too!\n pass\n\n# CORRECT: Specific exceptions, proper logging\ntry:\n result = process(data)\nexcept ValidationError as e:\n logger.warning(\"Validation failed\", extra={\"errors\": e.errors})\n raise\nexcept DatabaseError as e:\n logger.error(\"Database error during processing\", exc_info=True)\n raise AppError(\"Processing failed\", \"PROCESS_FAILED\") from e\n```\n\n### Go\n\n```go\n// Define sentinel errors and custom types\nvar (\n ErrNotFound = errors.New(\"resource not found\")\n ErrUnauthorized = errors.New(\"unauthorized\")\n)\n\ntype ValidationError struct {\n Field string\n Message string\n}\n\nfunc (e *ValidationError) Error() string {\n return fmt.Sprintf(\"validation: %s -

}>\n \n\nSidebar unavailable

}>\n \n\n```\n\n### Service Degradation\n\n```typescript\n// Graceful degradation: serve stale data when service is down\nasync function getProductRecommendations(userId: string) {\n try {\n return await recommendationService.get(userId);\n } catch (error) {\n logger.warn(\"Recommendation service unavailable, using fallback\", {\n userId,\n error: error.message,\n });\n return getCachedRecommendations(userId) || getDefaultRecommendations();\n }\n}\n```\n\n## Retry Patterns\n\n### Exponential Backoff\n\n```typescript\nasync function withRetry(\n fn: () => Promise,\n options: {\n maxRetries?: number;\n baseDelay?: number;\n maxDelay?: number;\n retryOn?: (error: Error) => boolean;\n } = {},\n): Promise {\n const {\n maxRetries = 3,\n baseDelay = 1000,\n maxDelay = 30000,\n retryOn,\n } = options;\n for (let attempt = 0; attempt <= maxRetries; attempt++) {\n try {\n return await fn();\n } catch (error) {\n if (attempt === maxRetries) throw error;\n if (retryOn && !retryOn(error as Error)) throw error;\n\n const delay = Math.min(\n baseDelay * 2 ** attempt + Math.random() * 1000,\n maxDelay,\n );\n logger.warn(\"Retrying operation\", { attempt: attempt + 1, delay });\n await new Promise((r) => setTimeout(r, delay));\n }\n }\n throw new Error(\"Unreachable\");\n}\n\n// Usage: retry only on transient errors\nconst data = await withRetry(() => fetch(\"https://api.example.com/data\"), {\n retryOn: (err) => err.message.includes(\"ECONNRESET\"),\n});\n```\n\n### Circuit Breaker\n\n```typescript\nclass CircuitBreaker {\n private failures = 0;\n private lastFailure = 0;\n private state: \"closed\" | \"open\" | \"half-open\" = \"closed\";\n\n constructor(\n private threshold: number = 5,\n private resetTimeout: number = 60000,\n ) {}\n\n async execute(fn: () => Promise, fallback?: () => T): Promise {\n if (this.state === \"open\") {\n if (Date.now() - this.lastFailure > this.resetTimeout) {\n this.state = \"half-open\";\n } else {\n if (fallback) return fallback();\n throw new Error(\"Circuit breaker is open\");\n }\n }\n\n try {\n const result = await fn();\n this.failures = 0;\n this.state = \"closed\";\n return result;\n } catch (error) {\n this.failures++;\n this.lastFailure = Date.now();\n if (this.failures >= this.threshold) this.state = \"open\";\n if (fallback) return fallback();\n throw error;\n }\n }\n}\n\n// Usage: trips open after 5 failures, resets after 30s\nconst paymentCircuit = new CircuitBreaker(5, 30000);\nconst result = await paymentCircuit.execute(\n () => paymentService.charge(amount),\n () => ({ queued: true, message: \"Payment will be processed shortly\" }),\n);\n```\n\n## Error Tracking Integration\n\n### Sentry Setup\n\n```typescript\nimport * as Sentry from \"@sentry/node\";\n\nSentry.init({\n dsn: process.env.SENTRY_DSN,\n environment: process.env.NODE_ENV,\n tracesSampleRate: process.env.NODE_ENV === \"production\" ? 0.1 : 1.0,\n beforeSend(event) {\n // Scrub sensitive data\n if (event.request?.headers) delete event.request.headers[\"authorization\"];\n return event;\n },\n});\n\nSentry.setUser({ id: user.id, email: user.email });\nSentry.captureException(error, {\n tags: { subsystem: \"payment\", provider: \"stripe\" },\n extra: { orderId, amount },\n});\n```\n\n## User-Facing vs Internal Errors\n\n```typescript\n// Map internal errors to user-friendly messages\nconst USER_MESSAGES: Record = {\n VALIDATION_ERROR: \"Please check your input and try again.\",\n NOT_FOUND: \"The requested resource could not be found.\",\n RATE_LIMITED: \"Too many requests. Please wait a moment.\",\n PAYMENT_FAILED: \"Payment could not be processed. Please try another method.\",\n INTERNAL_ERROR: \"Something went wrong. Please try again later.\",\n};\n\nfunction toUserResponse(error: AppError) {\n return {\n error: {\n code: error.code,\n message: USER_MESSAGES[error.code] || USER_MESSAGES[\"INTERNAL_ERROR\"],\n },\n };\n}","tagline":"Implements error handling patterns, structured logging, retry strategies, circuit breakers, and graceful degradation.
