A CLI dashboard for your webpack dev server. You can alternatively globally install the dashboard (e.g. npm install -g webpack-dashboard) for use with any project and everything should work the same. When choosing a custom port, you need to find one that is not already in use. You should not choose one that is being used by webpack-dev-server / devServer or any other process. Instead, pick one that is only for webpack-dashboard and pair that up in the plugin configuration and CLI port flag....
