Generating .js source maps using babel and webpack with Aurelia

I am trying to get js sourcemaps to be emitted when using webpack, babel-loader, and Aurelia (not sure if Aurelia even matters in this context, but I'm including it in case it does). I'm not even one week into learning how to use webpack. One thing I have had a lot of difficulty is getting js source maps to be emitted.

I have tried to use the answers at:

How do I generate sourcemaps when using babel and webpack?

and

Webpack-dev-server doesn't generate source maps

but unfortunately I am still just seeing 1.bundle.js and bundle.js as the script files in chrome's developer tools window.

Here I will include my package.json:

Don't judge me, I'm still learning all this. As you can see, I've enabled the -d option for webpack-dev-server command in the 'dev' script. I added: debug: true and devtool: 'source-map' but alas, I can't seem to find where these source maps are being emitted in the chrome developer tools; which has me concluding that they aren't being emitted at all.

I did find something interesting in the webpack://. domain; all my Aurelia js is there EXCEPT it looks like it's been converted by babel or webpack.
