When you click on the play button next to run, it will launch and run the program through the debugger. This will change the way your debugging side panel looks. Once you’ve completed this, you can save and exit the file. You can also configure the debugger to skip certain files listed under the skipFile array. For that particular situation, you just need to change it to whatever your main entry file is – which is typically something like app.js or index.js. Sometimes, depending on your file directory setup or version, the assigned value to the program may not match the entry main file to your application. const calculate = (A, B) => \src\app.js' To create our simple program, run npm init inside an empty project directory in your console.

We will then follow a debugging process that will give you the basic scope of how to use the debug tool in VSCode for Node.js. Step-by-step guide on debugging Node.js in VSCode Prerequisitesīefore we begin this tutorial, we will assume the following:įor this tutorial, we are going to set up a simple Node.js program with an error in it. Debugging becomes a common task for every developer as a side effect. While all the above is fantastic, there are bugs where there is code.

It uses an event-driven, non-blocking I/O model that makes it lightweight and efficient.

It is asynchronous, meaning that it can handle multiple requests simultaneously without waiting for each one to finish before starting the next.

Applications are single-threaded, meaning that a single process can handle multiple requests simultaneously.

Applications are written in JavaScript and can be run within the Node.js runtime on OS X, Microsoft Windows, and Linux.

Node.js is a cross-platform runtime environment that allows you to run JavaScript code on the server-side.

It is an open-source server-side JavaScript runtime environment.

These applications are often built on popular JavaScript frameworks and libraries such as Express, React, Angular, and Vue. Node.js apps are applications written in JavaScript that are executed on a server using the Node.js runtime environment.

Node.js has a large community of developers who have created a variety of modules that you can use in your own projects.

It is also popular on the Internet of Things (IoT). It is not a framework but a technology built on Chrome’s V8 JavaScript engine, allowing it to be used for developing server-side applications and command-line tools.

Node.js is a JavaScript runtime environment that allows you to run JavaScript code outside a browser. This tutorial will show you how to debug node.js in Visual Studio Code. Debugging tools can be integrated into code editors, making the debugging process more efficient.
