Production systems are complex, dynamic environments where issues can arise at any moment. The ability to effectively debug and troubleshoot production incidents is a critical skill that distinguishes a good engineer from a great one. This chapter delves into the practical aspects of identifying, diagnosing, and resolving problems in live Node.js applications.</p> <p>This section is particularly vital for mid-level, senior, staff, and lead engineers who are expected not only to write robust code but also to maintain the health and reliability of production systems. We will cover theoretical knowledge, practical tools, strategic approaches, and real-world scenario-based questions to equip you with the confidence and expertise needed to handle production challenges. Understanding these concepts demonstrates your maturity as an engineer and your readiness to take ownership of critical systems.</p>
