无法在 Visual Studio 代码中为“npx”启动的应用程序启动调试

Question

I need to launch a particular .js file for execution, in this way:

1. npx app.js launch.conf.js //for execution of scripts

2. npx app.js debug.conf.js //for debugging the scripts

In my debug.conf.js contains

const config = {
  debug: true,
  execArgv: ['--inspect-brk'],
  maxInstances: 1,
  cucumberOpts: {
    timeout: 30 * 1000 * 4,
  },
};
exports.config =config

, When I Execute the 2nd command via CMD I'm able to debug using chromedev Tools debugger. but when I need to debug using the VS code Editor:this is present in my launch.json file:

"type": "node",
"name": "manager",
"request": "launch",
"protocol": "auto",
//  "port": 5859,
"program": "${workspaceRoot}\\node_modules\\cdem\\bin\\app",
"execArgv": ["--inspect-brk"],
"args": [
    "run wdio.debug.conf.js"
]

I keep getting the console op as: debugger attached, waiting for debugger to disconnect and the execution is not launched.

Can someone let me how to debug this app using VS Code?

https://webdriver.io/docs/debugging provides details on how to run in VS code ( thank you Mike (comment) ):

1. Go to Run and Debug tab/blade ( Ctrl + Shift + D )

2. Create a launch.json file (eg type Node.js on environment bar) or click the cog at the top for other options

3. .vscode/launch.json opens up or locate and open it (from project's root folder)

4. Paste this in the configurations array, adjust according to your parameters/arguments and save the file:

    { "name": "run select spec", "type": "node", "request": "launch", // To run all spec files remove "--spec", "${file}" from below "args": ["wdio.conf.js", "--spec", "${file}"], "cwd": "${workspaceFolder}", "autoAttachChildProcesses": true, "program": "${workspaceRoot}/node_modules/@wdio/cli/bin/wdio.js", "console": "integratedTerminal", "skipFiles": [ "${workspaceFolder}/node_modules/**/*.js", "${workspaceFolder}/lib/**/*.js", "<node_internals>/**/*.js" ] },

5. Run the above by choosing this configuration (eg "run select spec") from the top left dropdown/select menu (or press F5 if already selected).
