Diagnosing issues with Chrome DevTools

Node.js offers a powerful debugging utility through the --inspect process flag, enabling us to debug and profile our Node.js processes using the Chrome DevTools interface. This integration is made possible by the Chrome DevTools Protocol, which facilitates communication between Node.js and Chrome DevTools. The existence of this protocol allows for the creation of tools that seamlessly integrate with Chrome DevTools, providing a unified debugging experience across different environments.

In this recipe, we will learn how to utilize Chrome DevTools to diagnose and resolve issues within a web application. We’ll cover how to set up the debugging environment, connect to a Node.js process, and navigate the various features of Chrome DevTools. This includes inspecting variables, setting breakpoints, and stepping through our code.

Important note

node --debug and node --debug-brk are legacy Node.js flags that have been deprecated since...
