Node Congress 2025

Have you ever struggled to track performance issues in your Node.js apps? Me too—it can feel like chasing ghosts in your code! That’s why I’m excited to share how AI can make this so much easier. In this talk, I’ll show you how AI can simplify performance debugging by analyzing CPU and memory usage, finding bottlenecks, and even pointing out potential memory leaks. You don’t need to be an expert or spend hours digging through data—just some practical tips and tools to help you make your apps run smoothly and efficiently. Let’s make performance tuning less stressful!

Large, legacy codebases often suffer from tangled dependencies, lack of modular boundaries, and monolithic "barrel" files that bundle together many modules. This makes the codebase difficult to understand, modify, and scale. In this talk, we'll explore strategies for "untangling the barrel" and simplifying a complex codebase to prepare it for migration to a monorepo architecture.We'll cover techniques for:- Analyzing your code for cyclic dependencies- Tools to help refactoring the code- Establishing coding guidelines and automation to control codebase complexity going forward
