Syntax error setting up nuxt/vue debugging with vs code

Question

I'm trying to set up debugging of a nuxt/vue project in vs code on win 10 . I'm using git-bash. I've found https://medium.com/@justin.ramel/nuxt-js-debugging-in-visual-studio-code-822ff9d51c77

Following the directions I've changed my package.json to

{
  "name": "nuxt4",
  "version": "1.0.0",
  "description": "My classy Nuxt.js project",
  "author": "hh",
  "private": true,
  "scripts": {
    "dev": "nuxt",
    "build": "nuxt build",
    "start": "nuxt start",
    "dev-debug": "node --inspect node_modules/.bin/nuxt",
    "generate": "nuxt generate"
  },
  "dependencies": {
    "cross-env": "^5.2.0",
    "glob": "^7.1.3",
    "nuxt": "^2.0.0",
    "vue2-google-maps": "^0.10.6",
    "vuetify": "^1.2.4",
    "vuex": "^3.0.1"
  },
  "devDependencies": {
    "nodemon": "^1.11.0",
    "stylus": "^0.54.5",
    "stylus-loader": "^3.0.2"
  }
}

Launch.json:

{
 "configurations": [
{
  "type": "node",
  "request": "attach",
  "name": "Attach to Nuxt",
  "port": 9229
  }
]

}

However:

$ npm run dev-debug

> [email protected] dev-debug E:\ENVS\js\nuxt4
> node --inspect=0.0.0.0 node_modules/.bin/nuxt

Debugger listening on ws://0.0.0.0:9229/4eda468d-39a4-4ddb-9a73-23e4fa60ed8e

          ^^^^^^^

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

The nuxt file giving the error is:

    #!/bin/sh
    basedir=$(dirname "$(echo "$0" | sed -e 's,\\,/,g')")

    case $(uname) in
        *CYGWIN*) basedir=$(cygpath -w "$basedir");;
    esac

    if [ -x "$basedir/node" ]; then
    "$basedir/node"  "$basedir/../nuxt/bin/nuxt.js" "$@"
    ret=$?
    else 
    node  "$basedir/../nuxt/bin/nuxt.js" "$@"
    ret=$?
    fi
    exit $ret

How can I get this working?

edit:

I eventually found that

"dev-debug": "node --inspect ./node_modules/nuxt/bin/nuxt",

got me past that error. However I have a new problem: when I try to debug I get:

It looks like im trying to run package.json. Any Idea how to fix this?

edit2:

after editing the launch json the following based on the articles:

{
  "type": "node",
  "request": "launch",
  "name": "Launch via NPM",
  "runtimeExecutable": "npm",
  "runtimeArgs": [
    "run-script",
    "dev-debug"
  ],

  "program": "${workspaceFolder}\\node_modules\\.bin\\nuxt",
  "args": [
    "invoke",
    "local",
    "-f",
    "<function-name>",
    "--data",
    "{}" // You can use this argument to pass data to the function to help with the debug
],
  // "program": "E:\\ENVS\\js\\nuxt4\\node_modules\\.bin\\nuxt",
  "port": 9229
}

I'm getting

any thoughts?

edit:

Getting a little closer with launch.json changed to:

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "node",
      "request": "launch",
      "name": "npm run dev",
      "runtimeExecutable": "npm",
      "windows": {
        "runtimeExecutable": "npm.cmd"
      },
      "runtimeArgs": [
        "run",
        "dev-debug"
      ],
      "port": 9229
    },
    {
      "type": "node",
      "request": "launch",
      "name": "Launch Program",
      "program": "${workspaceRoot}/start"
    },
    {
      "type": "node",
      "request": "attach",
      "name": "Attach to Port",
      "address": "localhost",
      "port": 9229
    }
  ]
}

I'm now able to attach debugger to process.it does not appear to stop at breakpoints though.

Answer 1

The article you are referencing mentions:

I was able to get this to work by changing the line to:

"dev-debug": "node_modules/.bin/nuxt --inspect"

Check if that would be enough.

Similarly, nuxt/nuxt.js issue 2528 includes:

currently got it working by following that article a little bit.

{
        "type": "node",
        "request": "launch",
        "name": "Launch via NPM",
        "runtimeExecutable": "npm",
        "runtimeArgs": [
          "run-script",
          "dev-debug"
        ],
        "port": 9229
      }

"dev-debug": "node --inspect node_modules/.bin/nuxt"

---

nuxt/nuxt.js issue 433 also includes:

The correct command for windows platform should look like this

"dev-debug": "node --inspect node_modules/nuxt/bin/nuxt",

The OP mentions:

"dev-debug": "node --inspect ./node_modules/nuxt/bin/nuxt",

---

Regarding the error message "Cannot launch program… setting the 'outFiles' attribute might help", the question "Cannot debug serverless application in Visual Studio Code" includes:

if I point at node_modules/serverless/bin instead, things work as expected:

"program": "${workspaceFolder}\\node_modules\\serverless\\bin\\serverless",

You have other clues in the comments of the article "Running and debugging AWS Lambda functions locally with the Serverless framework and VS Code".

---

The OP points to a tip illustrated in standard/standard issue 260:

debugger // eslint-disable-line

or:

/* eslint-disable no-debugger */

Also seen here, in the context of Google Chrome supports debugger command as a tool to setup a breakpoint in code.
See also "how to disable eslint rules when you need to".
