10/19/2023 0 Comments Webstorm node debuggerWith WebStorm, you can have several installations of Node.js and switch between them while working on the same project. For more details about plugins, see Managing plugins. Press Control+Alt+S to open the IDE settings and then select Plugins. Make sure the Node.js plugin is enabled in the settings. Make sure you have Node.js on your computer. See Node.js with Docker, Node.js via SSH, and Node.js with Vagrant for details. To run a Node.js application remotely, configure it as a remote interpreter. In most cases, WebStorm detects Node.js installations, configures them as interpreters automatically, and adds them to the list where you can select the relevant one. If you want to switch among several Node.js installations, they must be configured as local Node.js interpreters. If you follow the standard installation procedure, in most cases WebStorm detects Node.js itself.Īnd even if you have no Node.js on your computer, you can install it when creating a new Node.js application in the Create New Project dialog, see Creating a new Node.js application below. If you need Node.js only as a local runtime for your application or for managing npm packages, running JavaScript linters, build tools, test frameworks, and so on, just install Node.js. WebStorm integrates with Node.js providing assistance in configuring, editing, running, debugging, testing, profiling, and maintaining your applications. Here is my result package.json is a lightweight runtime environment for executing JavaScript outside the browser, for example on the server or in the command line. Open the package.json file and add a few commands inside the scripts section. But noted let’s set up one more thing before we will move to debugging. Nice! As a result it looks like everything is working. # compile source (you could also just run tsc) Let’s compile it and run it by executing the following commands. dist.Ĭonsole.log('Hello World! We will setup TypeScript debugging in WebStorm!') Find it in the file, remove the comment, and change it to. As for dist directory, we need to edit the parameter outDir. TypeScript compiler will scan src directory by default. Afterward we need to edit it a bit to make it work with my preferred directory structure. Open the directory in WebStorm, and then open the tsconfig.json file. Now time to edit TypeScript configuration and make it work as excepted with my directories. My preference is to use src directory for TypeScript files, and dist directory for compiled code. Now I would like to set up a basic directories structure. To make TypeScript work we need to install it and initialize it. We can create a directory and initialize npm there by following commands. Better to have some tools in the pocket that will allow you to use more power. However, I should say sometimes the program’s complexity makes console.log debugging pretty hard. Of course, you can debug with console.log and don’t use any external debugger. Also, all terminal commands might not work in Windows systems.Īnd one more important thing. Setup the TypeScript projectįirst of all, you should have installed NodeJS and WebStorm to make all scripts on commands works. It will tell tsc to build source maps and that will help WebStorm to know where to stop if you put a breakpoint. Long Story Short: you need to set sourceMap parameter in tsconfig.json to true. I will set up a project from scratch and show you how to make the WebStorm debugger work. If you want to put a breakpoint and check variable values, you have to tell the debugger where it should stop. After compilation code will not be the same. As you know, TypeScript code should be compiled into JavaScript before running in a browser or NodeJS. In this article, I want to show you how WebStorm can debug TypeScript code.
