in Nix it's the same for as long as I remember, both on NixOS and nix-managed home-manager on MacOS and Linux:

      neovim = {
        enable = true;
        vimAlias = true;
        vimdiffAlias = true;
        defaultEditor = true;
        plugins = [
          pkgs.vimPlugins.fugitive
          pkgs.vimPlugins.fzf-vim
          pkgs.vimPlugins.vim-gh-line
          pkgs.vimPlugins.vim-gutentags
          pkgs.vimPlugins.nvim-lspconfig
          pkgs.pkgs-unstable.vimPlugins.vim-go
          pkgs.pkgs-unstable.vimPlugins.zig-vim
        ];
        extraConfig = builtins.readFile ./vimrc;
        extraLuaConfig = builtins.readFile (pkgs.replaceVars ./dev.lua {
              inherit (pkgs) ripgrep;
            }).outPath;
      }
