How do I use the nix package?

[zoenglinghou]

I was following the documentation and replacing my nixOS deployment of conduwuit with tuwunwl by bascially replacing the flake, caches, and the package with pkgs.tuwunel, but nix reports that there is no package tuwunel available. Am I missing some configuration?

Thank you in advanced.

Currently Tuwunel is not in Nixpkgs repository. The packaging request is here.

However you can use flake.nix from Tuwunel repository as your flake input and use package defined in Tuwunel's flake.nix.

How to use Tuwunel package defined in flake.nix in Tuwunel repository:

# flake.nix
{
  description = "...";

  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs/nixos-25.05";
    tuwunel.url = "github:matrix-construct/tuwunel/v1.0.0";
  };

  outputs = { self, nixpkgs, tuwunel, ... }@inputs:
  {
    # your configuration...
  };

# configuration.nix
{ tuwunel, ... }:
{
  systemd.services."tuwunel" = {
    description = "Tuwunel Matrix server";
    wants = [ "network-online.target" ];
    after = [ "network-online.target" ];
    wantedBy = [ "multi-user.target" ];

    serviceConfig = {
      Type = "notify-reload";
      ReloadSignal = "SIGUSR1";
      ExecStart = "${tuwunel.packages."x86_64-linux".default}/bin/tuwunel --config /path/to/tuwunel.toml";
      User = "tuwunel";
      # see Tuwunel configuration example for more options
    };
  };
}

Thanks for the answer.

I am able to get the tuwunel package from the flake (pinned to the v1.0.0 tag)
I modified conduit.nix, specifically changing the option name and the binary name to keep my changes to my original config minimal.

Everything is working so far.

wantedBy = [ "multi-user.target" ];

serviceConfig = {
  Type = "notify-reload";
  ReloadSignal = "SIGUSR1";
