Using Node Inspector to debug a node.js server is a great tool to save time, help fix your code on the fly, and to have full control over your code and any of its corresponding forks. Node Inspector supports almost all of the debugging features of DevTools to navigate in your source files. # node-debug app.jsĬonsequently, this will load Node Inspector in your default browser that works almost exactly as the Chrome Developer Tools. To start your main Node application JavaScript file using the following command.

#Nodejs inspector install

Use the below command to install the node-inspector. Using Node inspector, we can debug the Node.js applications.

You could do the same thing by adding printouts to your code, but it’s a lot less convenient and flexible, so good developers will know how to use the power tools to debug their applications. A debugger allows us to stop the code when it gets to the place where you suspect a problem of logic or implementation, and to investigate whether it is really doing what you thought it would. In reality, systems may easily be so complex that just thinking hard isn’t enough. Application design helps us to keep simple things simple and to break down complex problems into simple ones. Why Start Debugging Node.js Server Advantages of Node.JSĮveryone can make mistakes in their code, whether it’s in node.js or Ruby on Rails. It is harder for complex systems in particular when various subsystems are tightly coupled as changes in one system or interface may cause bugs.

Consequently, debugging is part of the software testing process and is an integral part of the entire software development lifecycle. In software development, debugging involves locating and correcting code errors in a computer program. Introduction to Debugging Node.js Serversīefore we start debugging Node.js server using Node Inspector, let’s take a look at a couple of higher level topics. Inspect scopes, object, and variables properties.Setting breakpoints for the JavaScript code.It’s easy to step over, Step in, Step out, resume.Using Node Inspector you can hover your mouse over on the JavaScript expressions to view values in the tooltip.Node Inspector has some of the following useful features that it provides to debug Node.JS based applications. You can easily debug through all code blocks of JavaScript code by using its interface. Node Inspector is a great tool to be used for debugging Node.js applications using the Opera or Chrome browser. Advantages of using Node Inspector to debug NodeJS It provides certain advanced features like long/async stack traces that are too difficult to implement in Node Inspector.īefore we can get into how to debug a node.js server, we have to get into its more specific use-cases. The built-in debugger is developed directly by the V8/Chromium team. Node.js provides a built-in DevTools-based debugger which mostly deprecates Node Inspector. Node Inspector is a debugger interface for Node.js applications that use the Blink Developer Tools. It also provides a rich library of various JavaScript modules that simplifies the development of web applications using Node.js to a large extent. Not surprisingly, many large companies have exploited Node.js in production. It’s also lightweight, efficient, and its ability to use JavaScript on both frontend and backend opens new development paths. Node.js applications are written in JavaScript and can be run in the runtime Node.js on OS X, Microsoft Windows, and Linux. It has a unique I / O model that excels it for scalable and real-time situations for its increasingly demanding servers. Node.js is an open source, a cross-platform runtime environment for server and network-side application development. in this tutorial, we will take a deeper look at the importance of debugging a node.js server using Node Inspector. Coding a node.js application is no exception, and knowing how to debug a Node.js server is just as important as knowing how to code using Node.JS in the first place. Bugs and code come hand and hand, especially when building an application from scratch.
