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.
The Node.js Debugger Client is an external debugging tool that can be used in conjunction with your Node.js applications. It provides a graphical interface for debugging, making it easier to manage breakpoints, inspect variables, and control program flow. To use the Node.js Debugger Client, for example, Chrome browser.
Once installed, you can start your Node.js application with the debugging flag by running
node --inspect <your-app.js>. This flag enables the debugger client to connect to your application. The client typically listens on port 9229, and you can access it using a web browser. Here, you’ll find a user-friendly interface to manage breakpoints, inspect variables, and navigate the call stack.
The Node.js Debugger Client is especially useful when you need a visual and intuitive way to debug your applications. It simplifies the process, making it accessible to both novice and experienced developers. Furthermore, it provides the flexibility to debug Node.js applications running on remote servers.
By mastering the Node.js Debugger Client, you can enhance your debugging capabilities and streamline your development workflow. With the right tools at your disposal, you’ll be better equipped to tackle any issues that arise during Node.js development.
