How Do You Debug CPU Spikes In Node.js Applications? Are you struggling with sudden CPU spikes in your Node.js applications and unsure how to identify the root cause? In this detailed video, we'll guide you through effective methods to diagnose and resolve high CPU usage issues. We'll start by explaining what CPU spikes indicate and how they can impact your application's performance. You'll learn how to reproduce these issues locally using debugging tools, making it easier to analyze what’s happening during a spike. We’ll show you how to leverage Node.js built-in profiling features to generate detailed reports and flame graphs, which help pinpoint the functions responsible for CPU overload. Additionally, we’ll cover system-level tools like strace and perf to trace system calls and identify I/O waits or tight loops that may be causing problems. The video also emphasizes the importance of identifying blocking code, such as synchronous loops or heavy computations, and offers strategies to offload these tasks asynchronously or distribute them across worker threads. You’ll discover how third-party modules and native addons can contribute to high CPU usage and how to optimize or replace inefficient libraries. Finally, we’ll introduce monitoring tools like Clinic.js and PM2 that help track CPU usage in real time, enabling proactive management of your application's performance. By following these steps, you can systematically troubleshoot and fix CPU spikes, ensuring your Node.js apps run smoothly and efficiently.
