A batch job, in The Elm Architecture

At the end of my native Elm post I said I hoped my next elm-run project would be a REST API, or maybe replacing some small existing app. I lied a little. I went the other direction and grabbed something much bigger: a real batch job, inside a real (and fairly large) application I’m actually building. The fetch PoC was 80 lines of the most ordinary Elm imaginable. This one isn’t a toy, and that’s the whole point – Damir (who’s building elm-run) needs someone leaning on it at scale and reporting back what creaks, so that’s what I’ve been doing.
