![]() If it can't access it directly, VS Code will try to use the browser's network stack to request the source map. ![]() If it can't, you'll see errors in the Debug Console explaining which source maps failed to load, and why. When dealing with web applications, you'll want to make sure that the URL is something the debugger running in VS Code can access. Loading Source MapsĮach JavaScript file may reference a source map, by a URL or relative path. If not, our section on sourcemaps in Node.js contains guidance that applies to browser debugging as well. Most modern tools used for building web applications will work out of the box. ![]() The source map helps the debugger figure out how to map between your original code, and the code running in the browser. For example, TypeScript code is compiled to JavaScript, and many web applications bundle all their JavaScript files together. The JavaScript debugger in VS Code supports source maps that allow debugging transformed code. WebAssembly debugging in browsers is identical to Node.js, read more about WebAssembly Debugging here. See the section on Attaching to Browsers. address - TCP/IP address of the debug port.If not provided, it will attach to all browser tabs. url - If given, VS Code will attach to a tab with this URL.These attributes are only available for launch configurations of request type attach: runtimeArgs - Optional arguments passed when launching the browser.Valid versions include stable (default), canary, beta, and dev. runtimeExecutable - Either an absolute path to the browser executable to use, or the version of the browser to use.url - The URL to automatically open when the browser is launched.These attributes are only available for launch configurations of request type launch: See the section on Skipping uninteresting code. skipFiles - Automatically skip files covered by these glob patterns.smartStep- Try to automatically step over source code that doesn't map to source files.outFiles - An array of glob patterns for locating generated JavaScript files.This option is used for sourcemap resolution. Most often, and by default, the webRoot is your workspace folder. webRoot - The root directory for your source code.You can view the complete set of options in the vscode-js-debug options documentation. You can either "launch" a browser with your application, or "attach" to an existing browser that you started in debug mode.īelow is a reference of common launch.json attributes specific to browser debugging. An introduction into the creation and use of debugging configuration files is in the general Debugging article. Launch configuration attributesĭebugging configurations are stored in a launch.json file located in your workspace's. You can even add a host property to debug a browser running on a different machine. Now, you can press F5 or the Start button in the Run and Debug view to attach to the running browser. vscode/launch.json that looks like this: In most cases, you'll want to start a new instance of the browser to debug your webpage or file. Note: If you are just getting started with VS Code, you can learn about general debugging features and creating launch.json configuration files in the Debugging topic. Instructions for Node.js stepping over external code also apply to browser-based debugging. In this section, we'll go into more detail about configurations and features for more advanced debugging scenarios. Launch configs are the traditional way to set up debugging in VS Code, and provide you the most flexibility for running complex applications. Otherwise, it will try to find an installation of Chrome on your system instead. If your default browser is Edge, VS Code will use it to open the page. When you run this command, you'll be prompted for a URL to open, and the debugger will be attached. The simplest way to debug a webpage is through the Debug: Open Link command found in the Command Palette ( ⇧⌘P (Windows, Linux Ctrl+Shift+P)). We also have more detailed walkthroughs to get started with React, Angular, and Vue, as well as other debugging recipes. Use a launch config to launch a browser with your app.Clicking a link in the JavaScript debug terminal.Use the Open Link command to debug a URL.There are a couple ways to get started with it. Visual Studio Code includes a built-in debugger for Edge and Chrome. Configure IntelliSense for cross-compiling.
