🚀 Dashnix

Dashnix is a lightweight, NixOS-native service dashboard. It automatically scans your system configuration to discover enabled services and their assigned ports, presenting them in a clean, modern web interface.

No more manual bookmarking or hardcoding links—if it's enabled in your NixOS config, Dashnix finds it.

✨ Features

• 🔍 Zero-Hardcode Discovery: Scans config.services and options.services to find active ports (supporting .port, .settings.port, .listenPort, and more).
• 🛠 Customizable Watchlist: Define exactly which services to monitor via the watchedServices option.
• 🖼 Intelligent Icons: Automatically fetches favicon.ico from services. Includes specific fallback logic for apps like Bazarr that hide icons in non-standard paths.
• 🛡 Firewall Integration: Built-in openFirewall toggle to handle access automatically.
• 🎨 Modern UI: A responsive, dark-themed grid layout that looks great on desktop and mobile.

📦 Installation

Option A: Using Flakes (Recommended)

Add Dashnix to your flake.nix as a source input:

inputs = {
  dashnix-src = {
    url = "github:your-username/dashnix";
    flake = false;
  };
};

# In your outputs:
modules = [
  "${inputs.dashnix-src}/dashnix.nix"
];

OR

{
  inputs.dashnix.url = "github:snapsettle/dashnix";

  outputs = { self, nixpkgs, dashnix, ... }@inputs: {
    nixosConfigurations.my-machine = nixpkgs.lib.nixosSystem {
      specialArgs = { inherit inputs; };
      modules = [
        dashnix.nixosModules.default
        ({ ... }: {
          services.dashnix = {
            enable = true;
            openFirewall = true; # Optional: opens the dashboard port
            watchedServices = [ "jellyfin" "sonarr" "radarr" "bazarr" "qbittorrent" ];
          };
        })
      ];
    };
  };
}

Option B: Without Flakes (Traditional NixOS)

You can import the module directly from GitHub using fetchTarball in your configuration.nix:

{ config, pkgs, ... }:

{
  imports = [
    (builtins.fetchTarball {
      url = "https://github.com/your-username/dashnix/archive/main.tar.gz";
    } + "/dashnix.nix")
  ];
}

⚙️ Configuration

Configure the dashboard directly in your NixOS configuration files:

services.dashnix = {
  enable = true;
  port = 8081;             # Access the dash at http://your-ip:8081
  openFirewall = true;     # Automatically open the port in the firewall

  # Services to monitor (only shown if they are also enabled in your config)
  watchedServices = [
    "jellyfin"
    "transmission"
    "radarr"
    "sonarr"
    "bazarr"
    "prowlarr"
    "home-assistant"
    "uptime-kuma"
  ];
};

🧠 How it Works

1. The Scavenger Logic

NixOS modules often store ports in different places. Dashnix intelligently probes the following paths for every service in your watchedServices list:

• Standard: services.<name>.port
• Submodules: services.<name>.settings.port
• Arr-Suite: services.<name>.settings.server.port
• Legacy/Specific: portNumber or listenPort

2. Static Site Generation

Dashnix uses pkgs.writeText to generate a static HTML/JavaScript dashboard at build time. This means the dashboard itself is incredibly fast and has zero runtime dependencies other than Nginx.

3. Client-Side Asset Discovery

Because some apps return a 404 or a redirect when hitting /favicon.ico, the dashboard includes a JavaScript fallback loop. It attempts to locate the icon across several common directory structures (e.g., /static/images/) before falling back to a clean placeholder icon.

---

🛠 Advanced Usage

If you have a service that uses a non-standard NixOS module where the port is not exposed to the options tree, simply define the port explicitly in your config, and Dashnix will pick it up:

# Example: If a module uses an 'extraConfig' string instead of a port option
services.my-custom-app.port = 9000;
