Debugging with npm Debugger

66

#description

Debugging is a critical part of any programming language, and Node.js is no exception. One popular way to debug Node.js applications is by using the npm Debugger. The npm Debugger is a command-line tool that allows developers to set breakpoints in their code, step through the execution of their code, and inspect variables and objects at runtime.

To use the npm Debugger, developers can install it into their project using npm, Node.js' package manager. Once installed, they can launch the Debugger by running the command "node debug" followed by the name of their script.

For example:

 
                    
node debug server.js

This will launch the Debugger and stop at the first breakpoint encountered in the "server.js" script, allowing developers to step through the code and examine variables and objects in real-time.

In addition to basic debugging functionality, the npm Debugger also supports a range of more advanced features, such as conditional breakpoints, watch expressions, and the ability to execute custom JavaScript commands at runtime.

By using the npm Debugger, developers can quickly narrow down the source of bugs and issues in their code, leading to faster development cycles and more reliable applications.
