Building an application from scratch comes with lots of bugs and codes. So it is essential to understand the importance of Node Inspector to debug a Nodejs server. In this blog, we will drill down deeper at the importance of debugging a Nodejs server using Node Inspector.
What is Nodejs?
What is Node Inspector?
Node Inspector is a debugger interface purely developed by the V8/Chromium team for Nodejs applications. It uses the Blink Developer Tools, formerly WebKit Web Inspector.
While using Chrome DevTools inspector, the Node inspector organizes your Nodejs development cycle for a clear workflow.
However, it avails you the option of automatically opening and closing Chrome DevTools in a window. To open DevTools, click the “Open DevTools” button. If the process sets to close, once you end your debugging session, DevTools will close automatically.
Advantages of using Node Inspector to debug NodeJS SERVER
Node Inspector has some useful features that it provides to debug Nodejs based applications.
- It’s easy to step over-step in-step out and resume.
- Inspect scopes, objects, and variables properties.
Introduction: Debug Nodejs Servers WITH NODE INSPECTOR
Debugging is the predominant part of the whole software development cycle. In the software testing process, debugging is a much-needed functionality. When various subsystems are coupled, it likely to cause bugs. In particular, it is harder for complex systems to debug.
Thus, debugging in software development involves locating, correcting, and handling code errors in a computer program.
Why Start Debugging NodeJS Server
As everyone knows, it is common to make mistakes in code by the developers. Meanwhile, the debugger allows us to inspect the code on the go. Thus, this helps you to suspect a problem in implementation and application design.
But it is not convenient and flexible for large scale app development. Unlike the above-mentioned practice, an expert developer knows to use the power tools to debug their applications.
How to Debug a Nodejs Server WITH NODE INSPECTOR
Use the below command to install node-inspector to debug the Nodejs applications.
# npm install -g node-inspector
# node-debug app.js
This will load Node Inspector in your default browser, as the Chrome Developer Tools works. Such debugging features of Node Inspector support all the debugging features of DevTools to navigate in your source files.
Using Node Inspector is a great tool to debug a Nodejs server that saves your time greatly. It helps to fix all your code on the go and to have full control over code. With simple commands, debugging a Nodejs server is easy with Node inspector.
