# `PhoenixKit.Admin.Presence`
[🔗](https://github.com/BeamLabEU/phoenix_kit/blob/v1.7.164/lib/phoenix_kit/admin/presence.ex#L1)

Phoenix.Presence implementation for tracking anonymous and authenticated sessions.

This module provides real-time tracking of:
- Anonymous visitors (WebSocket connections without user_uuid)
- Authenticated users (with user_uuid)
- Session details like IP, User-Agent, current page, connection time

## Usage

Track anonymous session:
```elixir
PhoenixKit.Admin.Presence.track_anonymous(session_id, %{
  connected_at: DateTime.utc_now(),
  ip_address: get_connect_info(socket, :peer_data).address,
  user_agent: get_connect_info(socket, :user_agent),
  current_page: socket.assigns.current_path
})
```

Track authenticated session:
```elixir
PhoenixKit.Admin.Presence.track_user(user, %{
  connected_at: DateTime.utc_now(),
  session_id: session_id,
  ip_address: get_connect_info(socket, :peer_data).address
})
```
