[Docs & DX] Enhance and optimize logger.ts (Issue #143)

[chizzy192]

Context & Goal

This issue focuses on improving the src/observability/logger.ts component within the Docs & DX domain. Currently, the architecture assumes certain default behaviors that do not scale well under heavy load or edge cases. As our user base expands, we have identified several constraints in the current implementation that cause sporadic timeouts or sub-optimal data fetching patterns.

The primary goal of this issue is to refactor and harden the logic within src/observability/logger.ts to ensure optimal performance and resilience. The current implementation relies on sequential processing or lacks robust error handling, which could lead to cascading failures in downstream systems. By addressing this, we will improve the overall stability of the platform.

Furthermore, this refactor will set the foundation for upcoming features that rely heavily on this module. We need to ensure that the code is well-tested, documented, and follows our latest architectural guidelines. The new implementation must handle all known edge cases, properly sanitize inputs, and gracefully handle external dependency failures.

Your task is to analyze the current flow in src/observability/logger.ts, propose a more efficient algorithm or data structure, implement the changes, and verify them against our test suite. We expect a deep understanding of the domain and careful consideration of the trade-offs involved in your proposed solution.

Implementation Tasks

• Analyze the current implementation in src/observability/logger.ts.
• Refactor the logic to address the constraints mentioned above.
• Add robust error handling and logging.
• Ensure backward compatibility with existing consumers.

Technical Guidance

When refactoring src/observability/logger.ts, consider using the following pattern:

// Example snippet
try {
  // Your optimized logic here
  await processEfficiently();
} catch (error) {
  logger.error('Failed to process', { error });
  throw new AppError('Processing failed', 500);
}

Delivery Window

Expected delivery: 1-2 Days

Contribution Workflow

1. Branch off dev.
2. Commit using Conventional Commits.
3. Open a PR targeting dev.
4. Ensure all CI checks pass.

Acceptance Criteria

• Code in src/observability/logger.ts is optimized and hardened.
• Tests pass and coverage is maintained or improved.
• PR targets the dev branch.
• No regression in existing functionality.
