Mastering Node.js Debugging: Techniques with VSCode 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.

Visual Studio Code (VS Code) is a popular code editor that offers fantastic Node.js debugging capabilities. With the Node.js extension, you can set breakpoints, inspect variables, and step through your code with ease. To get started, you need to install the Node.js extension from the Visual Studio Code marketplace.

One of the advantages of using VS Code for Node.js debugging is its seamless integration with other Node.js tools and extensions. This makes it an excellent choice for developers who prefer an all-in-one solution.

Set breakpoint in the code

Once installed, you can set breakpoints in your code by clicking on the left margin of your code editor. When your application is running in debugging mode, it will pause when it reaches these breakpoints. You can then use the debugging panel to inspect variables, call stacks, and control the execution flow.
