{
      "name": "Launch app",
      "type": "node",
      "request": "launch",
      "args": [
        "src/main.ts"
      ],
      "runtimeArgs": [
        "-r",
        "ts-node/register",
        "-r",
        "tsconfig-paths/register"
      ],
      "cwd": "${workspaceRoot}",
      "protocol": "inspector",
      "internalConsoleOptions": "openOnSessionStart",
      "env": {
        "NODE_ENV": "local",
        "NODE_PORT": "9000"
      },
      "sourceMaps": true,
      "console": "internalConsole",
      "outputCapture": "std"
    }

@atul221282 You can ignore tsconfig-paths if you dont use path mapping in your project. In my project, I can setup debug for main app, unit test, e2e test. From my understanding, it is better that you dont use nodemon when setup debugging.

@immanuel192 Thanks for providing the another solution, I will definitely try. However this issue is still need a fix :)

I copied your config file and then started debugging from visual studio but it not launching the app. Can you please explain in few dot points the step that I need to take after adding the launch.json file

@atul221282 There was an issue opened for this in the VSCode repository. This issue has since been closed in favor of another one, marking the former as a duplicate. Hopefully, this is the same issue you're experiencing.

[atul221282]

@skreborn No this is not same as that one, I am saying running npm run start:debug with Auto Attach On should run the application in debug mode but it not happening. There are other issues as well but I want to keep this simple and see what is the actual problem

I tried your script and got debugging to work but whenever I make any change to file and refresh browser I don't see my change in browser. I have to restart the app and run the debug again. Is it expected behavior coz I think that is not right?

Actually, debugging has nothing to do with the framework itself - it's not an issue. I'll add a tutorial on how to debug apps to the docs soon (let's track this here - https://github.com/nestjs/docs.nestjs.com/issues/217)
