Configuration helpers for Tauri's built-in auto-updater.

The updater allows your desktop application to check for updates, download them, and apply them automatically. It uses Tauri's tauri-plugin-updater under the hood.

Setup

1. Generate signing keys:

    mix ex_tauri.signer generate
   

2. Configure the updater in your config/config.exs:

    config :ex_tauri,
      updater: [
        enabled: true,
        endpoints: ["https://releases.myapp.com/{{target}}/{{arch}}/{{current_version}}"],
        pubkey: "YOUR_PUBLIC_KEY_HERE"
      ]

3. The updater plugin will be automatically included when building with mix ex_tauri.build if updater.enabled is true.

Update Endpoint

Your endpoint must return a JSON response conforming to Tauri's update protocol. The simplest approach is to use GitHub Releases:

```elixir
config :ex_tauri,
  updater: [
    enabled: true,
    endpoints: ["https://github.com/user/repo/releases/latest/download/latest.json"],
    pubkey: "YOUR_PUBLIC_KEY_HERE"
  ]
```

Check for Updates from LiveView

Install the updater plugin (mix ex_tauri.add updater), then use check/1 and install/1:

```elixir
def handle_event("check_updates", _params, socket) do
  {:noreply, ExTauri.Updater.check(socket)}
end

def handle_event("tauri_response", %{"command" => "updater_check", "available" => true} = params, socket) do
  {:noreply, assign(socket, update_version: params["version"], update_available: true)}
end

def handle_event("tauri_response", %{"command" => "updater_check"}, socket) do
  {:noreply, assign(socket, :update_available, false)}
end

def handle_event("install_update", _params, socket) do
  {:noreply, ExTauri.Updater.install(socket)}
end
```

After a successful install, relaunch with ExTauri.App.relaunch/1 (requires mix ex_tauri.add process).
