#Debug node js webstorm code
This is the easiest one to implement, and it’s the fastest way to litter your clean code with extra lines of info - but it can also (sometimes) help you find and fix the error. In Java, it’s () in Python, it’s print(), you get the idea. It’s built in to Node.js and prints in the terminal just like it’s built into JavaScript and prints in the browser’s console. Console.log() - the tried and true standby, this one really needs no further explanation if you’ve ever written a line of JavaScript.There’s a number of ways to debug your misbehaving Node.js program, I’ve listed them out below with links to learn more if you so desire. Let’s go over the options and then I’ll show you the easiest way I’ve come across in my own development. You just can’t, and it stinks.īut it is possible to debug, it just takes a little more elbow grease. Unlike JavaScript in the browser, or Java with a powerful IDE like IntelliJ, you can’t just set breakpoints everywhere, refresh the page or restart the compiler and slowly walk through the code examining objects, evaluating functions and finding the mutation or missing variable, etc. Select the With JavaScript debugger checkbox.If you’ve ever had the pleasure of writing code for a Node.js project, you know what I’m talking about when I say debugging it to figure out what’s going wrong isn’t the easiest thing. For more information, see Configure browsers. To configure browsers, click and adjust the settings in the Web Browsers and Preview dialog that opens. Note that debugging of JavaScript client-side code is only supported in Google Chrome and in other Chromium-based browsers. To use a custom browser, select it from the list. To use the system default browser, select Default.
In the field below, type the URL address to open the application at.Ĭhoose the browser to use from the list next to the After launch checkbox. Select After launch to start a browser automatically when you launch a debugging session.
In the dialog that opens, switch to the Browser / Live Edit tab. Alternatively, select Edit Configurations from the list on the toolbar.įrom the list, select the Node.js run configuration to start together with a JavaScript Debug configuration. In this case, the JavaScript Debug configuration will start automatically every time you start the Node.js configuration.Ĭreate a JavaScript Debug configuration from the Node.js configurationįrom the main menu, select Run | Edit Configurations. You can do that in two ways:Ĭreate a JavaScript Debug configuration from the Edit Configurations dialog ( Run | Edit Configurations) and then click to start it, see Debugging an application running on an external web server for details.Ĭreate a JavaScript Debug configuration from the Live Edit tab when creating or editing a Node.js configuration. To do that, you need to create a separate JavaScript Debug configuration in addition to the Node.js configuration and run these two configurations together. With WebStorm, you can debug the server-side code of a Node.js application together with its client-side JavaScript code. Debugging the server- and the client-side codeĭebugging of JavaScript client-side code is only supported in Google Chrome and in other Chromium-based browsers.
