And thinking to myself: there’s got to be a less complex way to do this. They pretty quickly go down the rabbit hole of UUIDs, WebSockets, and security implications and I start to feel in over my head. It’s useful, but honestly, unless you’ve been programming for a while, it’s not exactly the easiest thing to decipher. Node.js documentation -inspect - The Node.js docs themselves understand debugging isn’t the easiest, so they’ve made a handy reference to help get people started.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 debugging options and then I’ll show you the easiest way I’ve come across to debug Node.js in my own development. You just can’t, and it stinks.īut Node 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. You can read more about sourceMapPathOverrides here.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. This is needed to map the files correctly to the file system, as our debugger relies on the source files for debugging. To overcome this we have introduced a sourceMapPathOverride option which allows VS Code to override paths inside the source map. ![]() If you are using a custom bundling solution you might need to provide Visual Studio Code with more information, as we have learned that many boilerplates/bundlers/setups are generating source-maps with incorrect paths to the files (on the file system). Help VS Code understand your source-maps with an extra option You’ll find a more detailed guide on how to do this in our new VS Code recipes repository on GitHub. You can also debug your Angular unit tests using VS Code. Start debugging in VS Code by pressing F5or going to the debug section select Launch Chrome with ng serve followed by clicking the green debug icon.ĭebugging Angular unit tests with VS Code.Start your Angular app by running ng serve in your favorite terminal.VS Code launch.json configs for angular-cli Create a launch.jsonfile to configure the VS Code debugger and put it inside.Create your Angular app using angular-cli.Make sure Chrome is at least version version 59 (see issue).Download the latest release of VS Code and install our Chrome debugger. ![]() Super-charged live editing and JavaScript debugging enables you to write and debug your Angular code without leaving the editor, and most importantly it enables you to have a more efficient development workflow, without context switching, because you stay inside your editor while you both author and debug □ □ □ Today I’m gonna show how you can achieve the same super-charged workflow for Angular by using angular-cli and Visual Studio Code. ![]() Demo of a click event handler in an Angular component being debugged and live edited from VS Codeīack in February I wrote a Medium post on How to Live edit and debug your React apps directly from VS Code powered by our Chrome debugger for VS Code and Webpack’s Hot Module Reloading mechanism.
