Cannot start debugger in Visual Code while developing in NodeJS

Question

I am trying to run my MEAN app through Visual Code debugger but I cannot start it. It is showing me a Cannot connect to runtime process, timeout after 10000 ms - (reason: Cannot connect to the target: connect ECONNREFUSED 127.0.0.1:58... error. I am running Node 8.1.0 and npm 5.0.3. This is my launch configuration file

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "launch",
            "name": "Launch via NPM",
            "runtimeExecutable": "npm",
            "windows": {
                "runtimeExecutable": "npm.cmd"
            },
            "runtimeArgs": [
                "run",
                "startdev"
            ],
            "port": 5858,
            "protocol": "inspector"
        }
    ]
}

Whenever I execute my program I run it using npm run startdev, startdev being a script in my package.json. How do I start the debugger?

EDIT:

I am running the app using npm run startdev where the startdev is

"startdev": "concurrently \"ng build --watch\" \"cross-env NODE_ENV=development nodemon ./bin/start.js\""

I also tried an attach configuration as such but to no avail

{
     "type": "node",
     "request": "attach",
     "name": "Attach to Process",
     "processId": "${command:PickProcess}",
     "port": 5858
}

You should use the attach configuration for attaching the debugger to a node process.

You will also need to start the process with the debug flag So something like

node --debug <filename>

Also as pointed out by OP in the comments, debug flag has been deprecated. So use inspect flag.

node --inspect <filename>

The attach configuration looks like { "name": "Attach", "type": "node", "request": "attach", "port": 5858, "address": "localhost", "restart": false, "sourceMaps": false, "outFiles": [], "localRoot": "${workspaceRoot}", "remoteRoot": null }

More about it in the docs here

Throws the same error. I have updated my question with more details

Just to clarify, you have started the node process with a debug flag right ? It logs to console upon a successful start, something like Debugger listening on [::]:5858 The startdev should be concurrently \"ng build --watch\" \"cross-env NODE_ENV=development nodemon --debug ./bin/start.js\

I get it now. I am running Node 8.1.10 where --debug is deprecated and node is crashing. I had to use --inspect instead. Also outDir is deprecated and outFiles needs to be used as "outFiles": []. If you edit your answer to include these, I will accept it.
