what is nix

  • pure functional

  • programming language

  • package manager

  • operating system

  • steep learning curve

  • sh <(curl -L https://nixos.org/nix/install) --daemon

  • https://search.nixos.org/packages

nix-shell

  • nix-shell -p nodejs
  • impure shell => not like a container
  • real version pinning is hard
    • is done with flakes
{ pkgs ? import <nixpkgs> {} }:
  pkgs.mkShell {
    buildInputs = with pkgs; [
      nodejs
      # nodejs-18_x
    ];

    shellHook = ''
      export FOO="hallo sternenwarte"
    '';
}
