You can advance the debugger by stepping through code ( F5, F10, and F11). While paused in the debugger, you can examine your app state by hovering over variables and using debugger windows. If necessary, take action to cause the code with the breakpoint to execute.

Browser extensions may be running and preventing full debug mode.īecause the code with the breakpoint may have already executed, refresh your browser page.

An operation is not legal in the current state.", use the Windows Task Manager to close all instances of the target browser before starting the browser in debugging mode. If the debugger does not attach and you see the message "Failed to launch debug adapter" or "Unable to attach to the process. Select your target browser as the debug target in Visual Studio, then press Ctrl+ F5 ( Debug > Start Without Debugging) to run the app in the browser. A source map must be configured correctly to support debugging in Visual Studio. vue, or JSX file typically requires the use of source maps. To find the specific code in a transpiled file, use Ctrl+ F ( Edit > Find and Replace > Quick Find).įor client-side code, to hit a breakpoint in a TypeScript file. (Set the breakpoint in a line of code that allows breakpoints, such as a return statement or a var declaration.) Switch to Visual Studio and then set a breakpoint in your source code, which might be a JavaScript file, TypeScript file, or a JSX file. To attach the debugger from Visual Studio and hit breakpoints in client-side code, the debugger needs help to identify the correct process. The app is not yet running, so you get an empty browser page.Īttach the debugger to client-side script This starts your browser with debugging enabled. Open the Run command from the Windows Start button (right-click and choose Run), and enter the following command: In complex debugging scenarios, you might also use Chrome Developer Tools or F12 Tools for Microsoft Edge instead.įor help to generate source maps, see Generate source maps for debugging. For example, in a Vue.js app, minified script gets passed as a string to an eval statement, and there is no way to step through this code effectively using the Visual Studio debugger, unless you use source maps. However, you may only be able to set and hit breakpoints in the minified or transpiled file, not in the original source file. Without source maps, you can still attach the debugger to a running client-side script. If your source is minified or created by a transpiler like TypeScript or Babel, the use of source maps is required for the best debugging experience.
For debugging client-side script in ASP.NET apps, see the blog post Client-side debugging of ASP.NET projects in Google Chrome.įor applications other than ASP.NET, follow the steps described here. In some scenarios, the debugger automatically hits breakpoints in JavaScript and TypeScript code and in embedded scripts on HTML files. Visual Studio provides client-side debugging support for Chrome and Internet Explorer only. You can use these tools to examine the DOM and interact with the app using the JavaScript Console. If you want to use the Chrome Developer Tools or F12 Tools, press F12. Now, you can inspect your app state by hovering over variables that are currently in scope, using debugger windows like the Locals and Watch windows. The debugger pauses at the breakpoint you set (the current statement is marked in yellow). To run your app, press F5 ( Debug > Start Debugging). A breakpoint indicates where Visual Studio should suspend your running code so you can take a look at the values of variables, or the behavior of memory, or whether or not a branch of code is getting run. With your project open in Visual Studio, open a server-side JavaScript file (such as server.js), click in the gutter to the left gutter to set a breakpoint:īreakpoints are the most basic and essential feature of reliable debugging.

Depending on the type of app development you're doing, you may need to install the Node.js development workload with Visual Studio. If you haven't already installed Visual Studio, go to the Visual Studio downloads page to install it for free.
