Mastering Node.js Debugging: Techniques with Command-Line for Smooth Development

Node.js Debugging is an integral part of the software development process. It’s the art of identifying and fixing issues in your code, ensuring that your application runs smoothly. When it comes to Node.js, a popular runtime environment for server-side applications, debugging is no exception. In this four-part blog series, we will explore various ways to debug Node.js applications, making your development journey more efficient and error-free.

Node.js comes equipped with a built-in command-line debugger that can be incredibly handy for identifying and resolving issues. To get started, you can insert the debugger; statement into your code at the point where you want to inspect. When your application reaches that line, it will pause execution, allowing you to examine variables, stack traces, and more. You can then use commands like c (continue) and n (next) to control program flow.

The built-in debugger also has a handy repl mode, which stands for Read-Eval-Print-Loop. In this mode, you can execute JavaScript code in the context of your running application, making it an excellent tool for experimenting with potential solutions.

How the debugger works

Node.js includes a command-line debugging utility. The Node.js debugger client is not a full-featured debugger, but simple stepping and inspection are possible.
