What to use for nodejs debugging

Node.js is a very popular server-side scripting language. It is based on Chrome's V8 engine and provides lightweight, efficient I/O operations, event-driven model and non-blocking asynchronous programming features. Despite the many advantages of Node.js, debugging issues still arise when developing Node.js applications. In order to solve these problems, developers need to use a stable and reliable debugging tool. So, what debugging tools are used for Node.js? Next, we will introduce some commonly used Node.js debugging tools.

1. Node-inspector

Node-inspector is a debugging tool for Node.js that uses the Chrome DevTools user interface to debug Node.js applications. Node-inspector is built on the basis of the browser and provides many common debugging functions, such as breakpoints, single-step debugging, viewing variables and executing functions, etc. Node-inspector makes it easy for you to find problems in your code and debug performance issues in your Node.js applications.

2. ndb

ndb is a Node.js debugger based on Chrome DevTools that provides quite a few advanced features. ndb is a very flexible debugging tool that requires no additional code in your Node.js application and does not explicitly start the Node.js process. ndb Use the command ndb to start the debugger, and you can also use Google Chrome's DevTools interface to interact with the application.

3. WebStorm

WebStorm is a very popular multi-platform JavaScript IDE that also supports Node.js. In WebStorm, you can use the built-in debugger to debug Node.js applications. WebStorm provides many common debugging functions, such as breakpoints, single-step debugging, viewing variables and executing functions, etc. WebStorm makes it easier to find problems in your code and improves your efficiency when debugging Node.js applications.

4. Visual Studio Code

Visual Studio Code is a very popular cross-platform code editor that also supports debugging of Node.js applications. In Visual Studio Code, you can use the built-in debugger to debug Node.js applications. Visual Studio Code provides many common debugging features, such as breakpoints, single-step debugging, viewing variables, executing functions, and more. Visual Studio Code makes it easier to find problems in your code and improves your efficiency when debugging Node.js applications.

5. Command-line debugger

The command-line debugger is a very basic tool for debugging Node.js applications from the command line. The Node.js runtime environment is available on nearly all platforms, and many developers prefer to use their familiar editor in a command-line environment. Node.js provides a built-in debugger that can debug Node.js applications through the command line interface (REPL). This debugging method requires developers to be familiar with the debugging commands provided by Node.js, such as break, watch, repl, etc.

Summary

Node.js provides a series of stable and reliable debugging tools, and developers can choose the appropriate debugging method according to their own needs. Debugging issues are very common when developing Node.js applications, so it is important to choose an efficient and flexible Node.js debugger. The Node.js community is also constantly updating and launching new debugging tools, allowing developers to more easily debug Node.js applications and improve application performance and reliability.
