New examples

[domenkozar]

Please, comment with what kind of an example you'd like to see.

Would be great to see an example (if it's possible) of how to wire up Python with specific packages; something equivalent to

pkgs.python3.withPackages (p: with p; [
  django
])

From https://nixos.wiki/wiki/Python.

The most complete devenv.nix I've found is https://github.com/cachix/devenv/blob/4787a79b00c5415139c2ae7029c8d870eea831e6/devenv.nix which doesn't have this wired up.

I'm currently trying to figure out how to use niv and devenv together (since the nix docs point you to both). I'm honestly not sure if this is a missing example or if the answer is "don't do that".

That's something I've been thinking quite a bit in the last days. There are different levels of language support and I still need to do a bit of experimentation. Regardless, this will be supported!

You don't need niv since you can use https://devenv.sh/inputs/

Worth noting that in practice, for applications withPackages isn't that useful since it doesn't have all the packages, and I'll probably end up using something like https://github.com/nix-community/poetry2nix.

I'm a PHP developer. I noticed there is a PHP-FPM service which is nice, but I'm wondering how to use it together with web server. Usual combination is NGINX + PHP-FPM, but looks like you don't provide nginx service? What's the recommended approach to use a php-fpm then, what to connect it to? Hence would be nice to provide example for HTTP server that connects to FPM.

+1 for Nginx support / setup.

[domenkozar]

I think @shyim mentioned recently to add nginx service

[Juhlinus]

I am currently using devenv within a PHP project. For now we are using caddy, but since caddy does not support file uploading out of the box, we wanted to switch to nginx.

Definitely a +1 to a nginx service.

[shyim]

Are you sure with file uploading? Never head problems with that. Tried now working :D

[ostrolucky]

In my setup, I simply run symfony serve. With that you don't need nginx. You need pkgs.symfony-cli.

Really? Using Laravel I am having issues uploading. I've tried setting the upload_tmp_dir explicitly. Is there a recommended folder to set this to? I'm going to try with a fresh Laravel app to make sure that it is not some configuration within the current app interfering.

[shyim]

If you have a reproducer repo I would like to debug it and fix it :)

[domenkozar]

There's now nginx at https://devenv.sh/reference/options/#servicesnginxenable

[frontsideair]

It would be really nice to have a Node.js/Postgres full-stack example. I tried to build one a few weeks ago but didn't work out smoothly. I think one of the reasons might be that I was using Prisma as my ORM, which may require some tweaking with socket files.

[domenkozar]

@frontsideair is there a getting started repo that devenv should work with?

[frontsideair]

This Remix template is a good candidate I think, it has a docker compose file and should work with minimal changes.

[pathetic-lynx]

I'd really like an example that shows how to wire up a devenv flake setup with a flake that exposes packages.

My current flake looks like this and is used together with direnv and use flake . --impure but the nativeBuildInputs declared in default.nix are not present in the shell. I think i am doing something fundamentally wrong or misunderstood the usecase of devenv. Is it even supposed to be used this way? Please enlighten me

{
  description = "myPackage";
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-23.05";
    flake-utils.url = "github:numtide/flake-utils";
    myDependency = {
      url =
        "git+ssh://git@our.git.com/myDependency";
      inputs.nixpkgs.follows = "nixpkgs";
    };
    code-generator = {
      url =
        "git+ssh://git@our.git.com/code-generator";
      inputs.nixpkgs.follows = "nixpkgs";
    };
    devenv = {
      url = "github:cachix/devenv";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };

  outputs = { self, nixpkgs, myDependency, devenv, code-generator, systems
    , flake-utils, ... }@inputs:
    flake-utils.lib.eachDefaultSystem (system:
      let pkgs = nixpkgs.legacyPackages.${system};
      in rec {
        packages = rec {
          default = myPackage-default;
          myPackage-default = pkgs.callPackage ./default.nix {
            pkgs = pkgs;
            myDependency = myDependency;
            code-generator = code-generator;
          };
          myPackage-prod = pkgs.callPackage ./default.nix {
            pkgs = pkgs;
            myDependency = myDependency;
            code-generator = code-generator;
            debug = false;
          };
        };
        devShells = {
          default = devenv.lib.mkShell {
            inherit inputs pkgs;
            # packages = packages.default.${system}.buildInputs ++ packages.default.${system}.nativeBuildInputs;
            modules = [{
              # https://devenv.sh/reference/options/
              pre-commit.hooks = {
                # TODO: add hooks for xml and json formatting
                alejandra.enable = true; # black for nix
                black.enable = true;
                clang-format.enable = true;
                # editorconfig-checker.enable = true;
                ruff.enable = true;
                shellcheck.enable = true;
              };
            }];
          };
        };
      });
}

Best to open a separate issue for each.
