webpack-dev-server

Actually, I believe you can already run webpack-dev-server with a multi-config just by making your webpack.config.js export an array instead of a single object. The article seems unaware of this capability, but you should be able to have both builds be part of a single webpack config file. See https://github.com/webpack/webpack-dev-server/blob/master/ex... for a simple example. I've used this before for web worker scripts (which require a different environment than the DOM) alongside a normal build.

I've had several experiences with Node.js contractors handing over "finished" applications that were only configured to run under webpack-dev-server[0] It clearly tells you in the README it's not for production, but I have this recurrent discussion with developers who tell me they have only ever run Node.js this way. What that tells me is there is quite a trend a towards exactly what you describe, where a lot of what gets written never goes into production. [0] https://github.com/webpack/webpack-dev-server
