Notification Manager Overview

Purpose

The Notification Manager module is designed to streamline the process of sending various types of alerts such as in-app notifications, emails, and SMS messages. It provides a centralized platform for developers to manage different notification channels efficiently.

Benefits

• Centralized Control: Manage all notification channels from one interface.
• Flexibility: Choose which notification methods (in-app, email, SMS) to use based on your needs.
• Reliability: Ensure notifications are delivered promptly and reliably.
• Scalability: Handle varying volumes of notifications without performance issues.
• Customization: Tailor messages for specific user actions or data.

Usage Scenarios

Triggering Notifications

• Send alerts in response to user actions like completing a task, receiving a new message, or achieving a milestone.

Error Handling

• Automatically notify users about failed operations, such as payment failures or API errors.

Personalization

• Deliver customized messages based on user preferences, location, or specific triggers.

Integration with Third-Party Services

• Connect with external services to enhance notifications, like push notifications via Firebase Cloud Messaging (FCM) or Apple Push Notification service (APNs).

Monitoring and Logging

• Track notification delivery status and handle retries for failed attempts, ensuring maximum reachability.

The Notification Manager module is an essential tool for developers aiming to deliver timely and effective communications within their applications.

Feature Name: Multiple Notification Channels

This module supports sending notifications through multiple channels including in-app push notifications, email, SMS, and third-party services like Slack or Pushover. Developers can configure these channels independently based on their requirements.

Feature Name: Template Customization

Notifications can be customized using template-based systems for emails, SMS messages, and in-app alerts. Templates allow developers to define placeholders for dynamic content such as user names, event details, or URLs, making it easy to adapt notifications to different scenarios.

Feature Name: Scheduling & Recurrence

Notifications can be scheduled to send at specific times or on a recurring basis. This feature is useful for sending reminders, follow-ups, or time-sensitive updates. Developers can set up one-time tasks or create complex schedules based on business logic.

Feature Name: Batch Processing

The module supports batch processing of notifications to optimize performance when sending large volumes of alerts. This reduces the overhead of individual API calls and ensures efficient resource utilization.

Feature Name: Testing & Simulation

Developers can test notifications without triggering actual sends by using simulation mode. This allows for debugging, previewing templates, and validating configurations before deploying them in production environments.

Feature Name: Delivery Status Tracking

Notifications are tracked to ensure successful delivery. The module provides logs and status updates for each notification attempt, including details such as failures, retries, or success metrics. This is essential for monitoring performance and troubleshooting issues.

Feature Name: Integration with External Services

The module can integrate with third-party services like email gateways (e.g., SendGrid), SMS providers (e.g., Twilio), and push notification platforms (e.g., Firebase Cloud Messaging). These integrations allow developers to leverage external infrastructure for reliable and scalable notification delivery.

Feature Name: Custom Events & Hooks

Developers can define custom events or hooks that trigger notifications based on specific actions within the application. This allows for tightly coupling notifications with business logic, such as alerting users when a specific condition is met or an event occurs.

Feature Name: Role-Based Access Control (RBAC)

The module includes role-based access control to manage who can view, modify, or delete notification configurations. This ensures that sensitive settings are protected and adheres to security best practices.

These features make the Notification Manager a robust and flexible tool for developers to implement scalable, reliable, and customizable alerting systems across various communication channels.

Overview

The Notification Manager module provides APIs to manage notifications across multiple channels (in-app, email, SMS). It allows developers to enable or disable specific notification types for users.

Code Samples

1. FastAPI Endpoint

from fastapi import APIRouter, Depends, HTTPException
from typing import Annotated
from ..models.notification import NotificationSettings
from ..database.models import User
from sqlalchemy.orm import Session
from fastapi.responses import JSONResponse

router = APIRouter(prefix="/notifications", tags=["notification"])

# Dependency to get the current user from the session
async def get_current_user(db: Session):
    user = db.query(User).first()
    if not user:
        raise HTTPException(status_code=401, detail="Authentication required")
    return user

@router.post("/", response_model=dict)
async def toggle_notifications(
    enable: bool,
    current_user: Annotated[User, Depends(get_current_user)],
    db: Session,
):
    """
    Toggle notification settings for the current user.
    """
    try:
        notification_settings = NotificationSettings(
            user_id=current_user.id,
            email_enabled=enable,
            sms_enabled=enable,
        )
        db.add(notification_settings)
        db.commit()
        return {"message": "Notifications updated successfully"}
    except Exception as e:
        db.rollback()
        raise HTTPException(status_code=500, detail=str(e))

2. React UI Snippet

import { useState, useEffect } from 'react';
import axios from 'axios';

const NotificationSettings = () => {
  const [isEmailEnabled, setIsEmailEnabled] = useState(true);
  const [isSmsEnabled, setIsSmsEnabled] = useState(true);

  useEffect(() => {
    fetchNotificationStatus();
  }, []);

  const toggleNotifications = async (enable: boolean) => {
    try {
      const response = await axios.post('/api/notifications', { enable });
      console.log(response.data);
    } catch (error) {
      console.error('Error updating notifications:', error);
    }
  };

  return (
    <div className="notification-settings">
      <h1>Notification Settings</h1>
      <div className="setting-item">
        <label>Email Notifications:</label>
        <button
          onClick={() => setIsEmailEnabled(!isEmailEnabled)}
          style={{ backgroundColor: isEmailEnabled ? '#4CAF50' : '#f44336' }}
        >
          {isEmailEnabled ? 'Enabled' : 'Disabled'}
        </button>

        <button
          onClick={() => setIsSmsEnabled(!isSmsEnabled)}
          style={{ backgroundColor: isSmsEnabled ? '#4CAF50' : '#f44336' }}
        >
          {isSmsEnabled ? 'Enabled' : 'Disabled'}
        </button>
      </div>
      <button

    email_enabled: bool = True
    sms_enabled: bool = True

    class Config:
        orm_mode = True
