Service Context

Centralized logging and error handling patterns for authentication services

Service Context

Overview

The service context system provides centralized logging and error handling for authentication operations. This creates consistent error reporting, debugging capabilities, and operational visibility across all authentication services.

Key Components

• Service Context Creation: Standardized logging and error handling setup
• Centralized Error Handling: Consistent error processing and reporting
• Structured Logging: Contextual logging with service identification
• Error Recovery: Graceful handling of authentication failures

Architecture Summary

1. Context Creation

   • Service-specific context with logging and error handling
   • Consistent error formatting and reporting
   • Structured logging with service identification

2. Error Handling Patterns

   • Centralized error processing
   • Configurable error propagation (rethrow vs. handle)
   • Contextual error information

3. Logging Strategy

   • Service-identified log entries
   • Structured logging for operational visibility
   • Debug information for development

Service Context Pattern

Context Creation

Each authentication service creates a context for consistent operations:

• Service identification for logging
• Standardized error handling methods
• Consistent logging patterns

Error Handling Methods

The service context provides error handling with options:

• Rethrow: Pass errors up the call stack
• Handle: Process errors locally and return safe responses
• Log: Record errors for debugging and monitoring

Logging Capabilities

Structured logging with service context:

• Service identification in all log entries
• Contextual information for debugging
• Operational metrics and monitoring

Usage Patterns

Service Implementation

Authentication services use the context pattern:

• Create service context with service name
• Use context methods for error handling
• Apply consistent logging throughout service

Error Recovery

Services implement graceful error handling:

• Catch and process authentication errors
• Provide meaningful error messages to users
• Log detailed information for debugging

Debugging Support

The context system supports development:

• Detailed error information in logs
• Service identification for issue tracking
• Consistent error formatting

Error Categories

Authentication Errors

• Invalid credentials
• Account not found
• Password strength validation failures
• OAuth provider errors

System Errors

• Database connection issues
• External service failures
• Configuration problems
• Network timeouts

Validation Errors

• Input validation failures
• Token validation errors
• Session validation issues
• Permission validation problems

Trade-Offs

Area	Decision	Benefit	Cost or Risk
Centralized Handling	Service context pattern	Consistent error handling	Additional abstraction layer
Error Propagation	Configurable rethrow	Flexible error handling	Complexity in error flow
Logging Strategy	Structured logging	Better debugging, monitoring	Log volume, performance impact
Context Creation	Per-service contexts	Service identification	Setup overhead per service

Why It Works for Nomey

• Creator platform → Clear error messages improve user experience
• Subscription model → Reliable authentication protects revenue
• Developer productivity → Consistent patterns reduce debugging time
• Operational visibility → Structured logging supports monitoring and alerts

The service context system ensures authentication operations are reliable, debuggable, and maintainable while providing consistent error handling across all authentication services.
