Answer 1

For people using Nrwl:

Launch.json (courtesy of @ghiscoding )

{
      "type": "node",
      "request": "attach",
      "name": "Attach NestJS WS",
      "port": 9229,
      "restart": true,
      "stopOnEntry": false,
      "protocol": "inspector"
    }

Terminal

ng serve nestjs_project --port 9229

Answer 2

This settings works for me

{
  "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"
}

Here is a config that works. Hope this helps someone :)

Make sure you add tsconfig-paths/register line under runtimeArgs else you will get an error saying some of your user defined modules were not found.

Also replace <YOUR_APP_ROOT_FOLDER> name with your application folder name if you have one under your root project folder, else remove it from the path in the script.

Note: Make sure to stop running your app before executing this debug config on vscode, because this debug script will launch a new instance of your app on the same port.

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "launch",
            "name": "Debug Nest Framework",
            "args": [
                "${workspaceFolder}/<YOUR_APP_ROOT_FOLDER>/src/main.ts"
            ],
            "runtimeArgs": [
                "--nolazy",
                "-r",
                "ts-node/register",
                "-r",
                "tsconfig-paths/register"
            ],
            "sourceMaps": true,
            "cwd": "${workspaceRoot}/<YOUR_APP_ROOT_FOLDER>",
            "protocol": "inspector"
        }
    ]
}

in launch.json have

{
// Use IntelliSense to learn about possible attributes.

  "version": "0.2.0",

        "request": "launch",
        "name": "Debug Nest Framework",
        "args": ["${workspaceFolder}/src/main.ts"],
        "runtimeArgs": ["--nolazy", "-r", "ts-node/register"],
        "sourceMaps": true,
        "cwd": "${workspaceRoot}",
        "protocol": "inspector"
    }
   ]
  }
