Vue simple-webpack on c9

I've lost track of how many times I've had to re-research this issue so I thought I'd best document it here. When playing through tutorials on Vue I often use c9 but had problems figuring out how to get the simple-webpack versions running. This, then, is how to get it up and running with a the vue-cli.

Open webpack.config.js and turn off the host check by adding this to the devServer object:

devServer: {
    historyApiFallback: true,
    noInfo: true,
    overlay: true,
    disableHostCheck: true
}

Then open package.json and alter the dev scripts object so it looks like this:

"cross-env NODE_ENV=development webpack-dev-server --host $IP --port $PORT --open --hot"

Of course, this works for me but YMMV.
