How I use Nix in my Elm projects

• elm-7guis

  3 11 8.7 HTML

  7GUIs in Elm.

Here's an example shell.nix taken from my elm-7guis web application.

• nixpkgs

  974 15,656 10.0 Nix

  Nix Packages collection & NixOS

  

let pkgs = import (fetchTarball "https://github.com/NixOS/nixpkgs/archive/7f256d7da238cb627ef189d56ed590739f42f13b.tar.gz") {}; in pkgs.mkShell { packages = [ pkgs.caddy pkgs.elmPackages.elm pkgs.elmPackages.elm-format pkgs.elmPackages.elm-optimize-level-2 pkgs.elmPackages.elm-review pkgs.elmPackages.elm-test pkgs.nodejs_18 pkgs.shellcheck ]; shellHook = '' export project="$PWD" export build="$project/.build" export PATH="$project/bin:$PATH" ''; }

• ShellCheck

  488 34,995 8.7 Haskell

  ShellCheck, a static analysis tool for shell scripts

When I run nix-shell at the root of the project it puts me in a Nix shell that contains, among other programs, caddy and shellcheck. Notice that in the shellHook I add the project's shell scripts to the PATH. So once I'm in the Nix shell I can, among other things:

• elm-integer

  1 5 8.1 Elm

  The integers, ℤ = { ..., -2, -1, 0, 1, 2, ... }.

Here's an example flake.nix taken from my elm-integer library.

• nix

  372 10,879 10.0 C++

  Nix, the purely functional package manager

  

Nix is a tool that allows you to make reproducible development environments. I've started using it in all my Elm side projects and I've had a good experience with it thus far. To pique your curiosity I just wanted to share my simple setup that has been working quite well for me.

• jq

  52 29,042 9.4 C

  Command-line JSON processor

  

In some projects I've wanted to use HTTPie to test APIs and jq to work with some JSON data. Nix has been really helpful in managing those dependencies that I can't easily get from npm.

• httpie
