    Sometimes your system may display an error that Javascript is required to debug Visual Studio. There can be several reasons for this problem.

    You can debug and code TypeScript with Visual Studio. You can set and hit breakpoints, attach a specific debugger, inspect variables, view the call stack, and use other debugging features.

    Server Side Script Debugging

    How do I debug JavaScript in Visual Studio?

    With the project open in Visual Studio, open a server-side JavaScript file (server.js for example) and click the left bar next to the bar to set a breakpoint:To run the application, press F5 (Debug > Start Debugging).PressPress F5 to continue using the application.

    1. With your project open in Visual Studio, open a server side JavaScript trace (e.g. server.js), in the current lane, click the left lane to set a breakpoint:

      Breakpoints are a fundamental and important feature of well-designed debugging. A breakpoint indicates where Visual Studio should stop executing code so you can check the values โ€‹โ€‹of variables or possibly memory behavior, and also see if a programming branch is running. /p>

    2. To run the app on your smartphone, press (F5 Debug > Start Debugging).

      The debugger stops at a single-statement breakpoint (i.e.The current highlighted operator is literally yellow). You can now check the status of your application by hovering over Done for the variables that are currently available using debug windows such as the Local and Control windows.

    3. Press F5 and continue working in the application.

    4. If you want to use the Chrome developer tools or F12 tools, press F12. You can use these tools to explore the DOM and interact with your application using the JavaScript console.

    Debugging A Script On The Client Side

    How do I enable debugging in Visual Studio?

    Select your C# or Visual Basic plan in Solution Explorer and select the “Properties” icon type, press Alt+Enter i.e. right click and select “Properties”. Select the “Debug” tab, then select “Enable Antiquities for Code Debugging”. Close the property profile to save your changes.

    Visual only supports Studio client-side debugging for Chrome and Microsoft Edge (Chromium). In some scenarios, the debugger automatically generates breakpoints in JavaScript and TypeScript exchanges and inline scripts in HTML files. For more information about client-side debugging when writing ASP.NET applications, see the JavaScript Debugging in Microsoft Edge blog post and therefore this Google Chrome post. . NET Core and see Create an ASP.NET Core phone app using TypeScript.

    Visual Studio provides a debugging company on a stand Not a client for Chrome and Internet Explorer only. In some scenarios, the debugger will typically automatically set breakpoints in JavaScript code, as well as in TypeScript code and built-in code in HTML files. For more information about client-side debugging in script-only ASP.NET applications, see the blog post Debugging ASP.NET Client-Side Projects in Google Chrome.

    Preparing The Smartphone Application For Debugging

    If your source code was minified or generated by a transpiler like TypeScript or Babel, use source maps generated by for better debugging No diagram source code , you can still attach our custom debugger to run a client-side script, the Vue.js application would be minified by the entry passed as a string to the eval statement, and there was no way to efficiently step through certain code with the Visual Studio debugger, unless you are using source routes, you can use Chrome Tools or F12 Tools for Microso insteadft Edge.

    Prepare Browser For Debugging

    For this location, use either Microsoft Edge (Chromium), which is currently called Microsoft Edge Beta in the IDE, or Chrome.

    1. Close any target browser windows you see.

      Other browser instances can sometimes prevent the browser from being enabled for debugging. (Browser extensions can run and prevent full mode. Debugging so much you might have to open Task Manager to find unexpected Chrome features.)

      For Microsoft Edge (Chromium), close all instances of Chrome. Since both browsers additionally use the Chromium code, I would say that the most popular results are achieved.

    2. Launch a browser with debugging enabled. In

      When running Visual Studio 2019, you can set the --remote-debugging-port=9222 flag when launching a mobile browser by selecting “View With” on the debug toolbar . ..” select. then how to chooseAdd, and then check the Arguments box. Use another friendly web browser name, such as Edge with debug or Chrome with debug. See Release Notes.

      for details

      You can also open the Run command with the Windows button, run the build (right-click and select Run) and type the following command:

      msedge --remote-debugging-port=9222

      or

      chrome.exe --remote-debugging-port=9222

      How do I debug JavaScript in Visual Studio 2008?

      In fact, the debugger can be enabled from the Debug menu in Visual Studio 2008. Go to the Debugging | Start to be able to start a debug session or new media [F5].

      Open the Run command using the Windows Start button (right-click and select Run), optionally type the following command:

      debug javascript visual studio

      chrome.exe --remote-debugging-port=9222

      This will launch your browser with debugging enabled.

      debug javascript visual studio

      The instance is not yet running so the user gets a blank browser page.

    Attach The Entire Debugger To The Client Script

    In order to attach debugging visuals from Studio and access breakpoints in client code, the master debugger needs help identifying the correct process. Here is a way that can make it possiblem.

    1. Switch to Visual Studio and then set a breakpoint in your own source code, whether it’s a JavaScript file, a TypeScript file, or a good solid JSX file. (Set breakpoints on any line of code that allows breakpoints, such as a return clause or a var declaration.)

      How do I debug a .JS file?

      Step 1: Reproduce my error.Step 2: Familiarize yourself with the Sources panel interface.Step 3: Stop codes with a breakpoint.Step 4: Step using the code.Step 5: Set a breakpoint for each line of code.Step 6: Check the values โ€‹โ€‹of the variables. Method 1: Polygon area. Little method: watch the expressions.Step 7: Apply a great solution.Next steps.

      To find the exact specific code a in the migrated folder, use Ctrl+F (Edit > Find or Replace > Quick Find).

      For client-side code, hitting a breakpoint in any typescript, .vue, jsx or doc file usually requires usage related to source maps. The source map must be properly configured. to support debugging next to Visual Studio.
