Is there a way to leverage running the webpack-dev-server on https when configuring using CLI?
The problem is the connection to
socket.iois overhttpand nothttps.
A workaround exists, but its very annoying.
- Manually include https 
webpack-dev-serverin yourindex.html 
<script src="https://localhost:8080/webpack-dev-server.js"></script>
- Configure each end point to include 
webpack/hot/only-dev-server. 
app: [
    'webpack/hot/only-dev-server',
    './app.js'
],
// ... more entry points that include the same [] ...

Yes there is a way to configure webpack-dev-server on https when configuring using CLI.
The solution is to not use --inline option.
There are many ways to configure the server and --hot. The one to follow, assuming your not creating a custom server implementation/middleware (Might be the same), is detailed in the docs.
http://webpack.github.io/docs/webpack-dev-server.html#webpack-dev-server-cli
- Do not include 
<script src="https://localhost:8080/webpack-dev-server.js"></script> - Do not include 
webpack/hot/only-dev-serverinto the entry. 
package.json
{
  "scripts": {
    "start": "webpack-dev-server -d --hot --https --config webpack.config.development.js"
  }
}
webpack.config.development.js
var webpackConfig = require('webpack-config');
module.exports = webpackConfig.fromCwd().merge({
    devServer: {
        colors:             true,
        contentBase:        './build',
        historyApiFallback: true,
        inline:             true,
        progress:           true
    },
    devtool: 'eval-source-map'
});
Main webpack configuration is not listed here.

I think you might add this line to the entry point to also create a secure socket connection:
"dev-server": "webpack-dev-server/client?https://localhost:8080/",

I used like this in package.json and started working with port i needed:
"scripts": {
  "serve": "webpack-dev-server --inline --colors --watch --display-error-details --display-cached  --port 3001 --hot"
},
