I’ve built myself a “lightweight web framework” with plug+cowboy for Nerves devices pretty frequently for things like configuration utilities. Once you build in ecto and templating, you’ve essentially got yourself what you get from mix phx.new --no-ecto --no-brunch but it doesn’t have the same level of maturity/usability as the phx.new version.
That being said it isn’t particularly hard, and it can be kept to about one/two + templates which is nice.
