Node.js Profiling Tools
Node.js profiling tools are utilities and techniques used to analyze the performance of Node.js applications by measuring CPU usage, memory consumption, and execution time. They help identify bottlenecks, memory leaks, and inefficient code to optimize application speed and resource efficiency. Common tools include built-in Node.js modules like the V8 inspector, as well as external libraries and command-line interfaces.
Developers should use Node.js profiling tools when building high-performance applications, especially in production environments where efficiency is critical, such as web servers, APIs, or real-time systems. They are essential for debugging performance issues, reducing latency, and ensuring scalability by pinpointing slow functions or memory-intensive operations.
