Elm + Nix: A reproducible RealWorld clone

Source: Dev.to

Nix has infected my soul. I don’t know how else to describe it.

I refactored my RealWorld clone, dwayne/elm-conduit, to use Nix. It uses Nix for the development environment, building, serving, running checks, deploying, and CI.

Quick commands (requires Nix)

• Frontend workshop environment

  nix run github:dwayne/elm-conduit#workshop

• Sandbox

  nix run github:dwayne/elm-conduit#sandbox

• Development version of the web app

  nix run github:dwayne/elm-conduit

• Production version (same as the Netlify deployment)

  nix run github:dwayne/elm-conduit#prod

The Elm builds are all powered by dwayne/elm2nix.

The Classics

This completes my refactoring of “The Classics” to use Nix.

• TodoMVC – nix run github:dwayne/elm-todos#prod
  Repository:

• Super Rentals – nix run github:dwayne/elm-super-rentals#prod
  Repository:

• 7GUIs – nix run github:dwayne/elm-7guis#prod
  Repository:

• Conduit – nix run github:dwayne/elm-conduit#prod
  Repository:

All of these projects now use Nix in the same way, providing a consistent workflow for combining Elm and Nix.
