How I use Nix in my Elm projects

1. elm-7guis

   1 6 16 3.3 HTML

   7GUIs in Elm.

   

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

2. Judoscale

   Save 47% on cloud hosting with autoscaling that just works. Judoscale integrates with Django, FastAPI, Celery, and RQ to make autoscaling easy and reliable. Save big, and say goodbye to request timeouts and backed-up task queues.

   

3. nixpkgs

   2 1,030 20,038 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" ''; }

4. ShellCheck

   3 499 37,208 8.0 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:

5. elm-integer

   4 3 5 8.1 Elm

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

   

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

6. nix

   5 404 14,052 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.

7. jq

   6 79 31,542 8.8 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.

8. httpie

   7 132 35,299 6.6 Python

   🥧 HTTPie CLI — modern, user-friendly command-line HTTP client for the API era. JSON support, colors, sessions, downloads, plugins & more. (by httpie)

9. InfluxDB

   influxdata.com featured

   InfluxDB high-performance time series database. Collect, organize, and act on massive volumes of high-resolution data to power real-time intelligent systems.

   

10. Caddy

    8 434 63,194 9.4 Go

    Fast and extensible multi-platform HTTP/1-2-3 web server with automatic HTTPS

    

    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:
