django-live-logs 0.1.2

A standalone Django package to stream logs over WebSockets.

Django Live Logs

A lightweight, zero-configuration package that streams your Django server logs directly to a beautiful, real-time web dashboard using WebSockets and Redis.

(Imagine a beautiful dark-mode dashboard here)

Features

• 🚀 Real-Time Streaming: Uses Django Channels and Redis to push logs instantly.
• 🎨 Built-In Dashboard: Comes with a sleek, dark-mode Tailwind CSS interface out of the box.
• 🛡️ Secure by Default: Dashboard and WebSockets are natively protected by Django's @staff_member_required and Session cookies.
• 🧵 Non-Blocking: Dispatches logs in a background thread to prevent ASGI async event loop collisions.
• 🔍 Filtering: Instantly filter between INFO, WARNING, and ERROR logs.

1. Installation

Install the package via pip:

pip install django-live-logs

Note: This package requires channels and channels-redis to be installed and configured in your project.

2. Configuration

Step A: Update settings.py

Add the package to your installed apps:

INSTALLED_APPS = [
    # ...
    'django_live_logs',
]

Configure your LOGGING dictionary to catch everything (the root logger) and send it to the WebSocket handler:

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'handlers': {
        'console': {'class': 'logging.StreamHandler'},
        'websocket': {'class': 'django_live_logs.handlers.WebSocketLogHandler'},
    },
    'root': {
        'handlers': ['console', 'websocket'],
        'level': 'INFO',
    },
    'loggers': {
        'django': {
            'handlers': ['console', 'websocket'],
            'level': 'INFO',
            'propagate': False,
        }
    },
}

Step B: Route the Dashboard (HTTP)

In your main urls.py, include the dashboard URL:

from django.urls import path, include

urlpatterns = [
    # ...
    path('live-logs/', include('django_live_logs.urls')),
]

Step C: Route the WebSockets (ASGI)

In your asgi.py, make sure your WebSockets are wrapped in Django's AuthMiddlewareStack so it can read your admin session cookies securely. Then include the routing:

from channels.auth import AuthMiddlewareStack
import django_live_logs.routing

application = ProtocolTypeRouter({
    "http": get_asgi_application(),
    "websocket": AllowedHostsOriginValidator(
        AuthMiddlewareStack(
            URLRouter(
                # Your existing websocket routes + Live Logs routes
                your_app_routing.websocket_urlpatterns + 
                django_live_logs.routing.websocket_urlpatterns
            )
        )
    ),
})

3. Usage

1. Log into your standard Django Admin panel (e.g., /admin/).
2. Navigate to /live-logs/ in your browser.
3. Click Connect.
4. Watch your server logs flow in real-time!

How it Works

The custom WebSocketLogHandler intercepts Python logs. Instead of blocking the main thread, it tosses the log payload to a daemon thread. The daemon thread safely uses async_to_sync to dispatch the JSON payload to the Redis Channel Layer. Finally, the Django Channels WebSocket consumer securely beams it to the authenticated frontend UI.
