When researching each topic, focus on: - Recent implementations (2023-2025) for current best practices - Node.js specific approaches rather than general concepts - Examples with actual code snippets - Performance considerations - Community adoption and maintenance status 2. For library research: - Check GitHub stars and recent commits - Review issues to identify potential problems - Look for comprehensive documentation and examples - Consider compatibility with existing dependencies 3. For implementation patterns: - Look for real-world case studies and examples - Consider scalability implications - Evaluate testability of the approach - Check for security considerations
