vscode node debugger with custom webpack build

I have a JS web app that has a client and server bundle, both built using webpack's node api.

Running my project in dev mode goes through these steps:

1. Run two webpack builds, resulting in two output files.
2. Server bundle is output to dist/server/index.js
3. Spawn child node process using the dist/server/index.js path
4. Watch folder for changes. On change, kill the old child process and re-run steps 1-3

I want to add node server debugging using vscode.

So far, I've added the following flags during step 3, when I launch a new child process.

['--inspect=9222', '--no-lazy', '--inspect-brk']

My launch.json file in vscode looks like this

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Attach to dev server",
            "type": "node",
            "request": "attach",
            "protocol": "inspector",
            "address": "localhost",
            "port": 9222,
            "restart": true,
            "trace": true,
            "stopOnEntry": true
        }
    ]
}

When I start the server and run the debugger, things mostly work.

However, I'd love to fix the following two things:

1. Even with "stopOnEntry": true, the debugger will not pick up any breakpoints, unless I include "--inspect-brk" when launching my child process. This is annoying, because if I'm not running the debugger, the process will hang and will not continue execution. With this flag included, when I run the debugger, the built dist/server/index.js file will open in my editor with a breakpoint on line 1. If I hit continue, all future debugging works.
2. I'm generating sourcemaps using webpack's "inline-source-map" option. This puts the "original source" in the built file. However, it's the source after babel transformation, making debugging the code a little annoying. E.g. _myFunction.default instead of myFunction. Does vscode have a way to correctly map the built .js file to the pre-built source code in my project? I saw the remoteRoot and localRoot options, but could not get them to work (and am unsure if these are the correct options).

Thanks!
