Installation

pip install fastpluggy-notification-center

Features

• Topbar bell icon — unread badge count, slide-out notification panel
• Event bus integration — listens to all notification.* events automatically
• Pluggable channels — any plugin can register as a delivery channel via the NotificationChannel protocol
• Channel relay — forward notifications to external channels (ntfy, email, etc.) based on category
• Web Push — browser push notifications via VAPID (auto-generates keys on first load)
• Notification categories — info, success, warning, error with colored badges
• Read/unread tracking — mark individual or bulk mark-as-read
• Auto-cleanup — configurable retention period (default 30 days)

Configuration

Settings are managed via NotificationCenterSettings (database-backed). Configure through the FastPluggy settings UI.

Usage

Sending notifications via event bus

Any plugin can emit a notification event:

fast_pluggy.events.emit("notification.info", payload={
    "title": "Task completed",
    "message": "Backup finished successfully",
    "category": "success",
    "data": {"task_id": 42},
})

Sending browser push notifications

fast_pluggy.events.emit("notification.push", payload={
    "title": "Deployment ready",
    "message": "v1.2.0 is live",
    "url": "/plugin/ecosystem_status/",
})

Explicit relay to all channels

Bypasses the category filter:

fast_pluggy.events.emit("notification.relay", payload={
    "title": "Critical alert",
    "message": "Database connection lost",
    "category": "error",
})

Registering a delivery channel

Any plugin can act as a delivery channel by implementing the NotificationChannel protocol:

from fastpluggy_plugin.notification_center.channels import NotificationChannel

class MyChannel:
    channel_name = "my_channel"

    def send(self, title, message, category, data=None):
        # deliver the notification
        ...

class MyPlugin(FastPluggyBaseModule):
    notification_channel = MyChannel()

The notification center discovers channels automatically at startup.

Dashboard

The notification panel is accessible via the topbar bell icon on every page. A full notification history page is available at /plugin/notification_center/ (CI) or /plugin-pkg/notification_center/ (local dev).
