Notification System Builder

Overview

Builds unified notification systems across email, SMS, push, and in-app channels.

Decision Framework

When to use

• User needs updates from multiple sources
• Multiple delivery channels required
• User preferences for notification types needed

When NOT to use

• Simple single-channel alerts
• Real-time streaming data

Decision Tree

Is notification user-triggered?
├── Yes → In-app toast + optional email
├── No → Is it time-sensitive?
│   ├── Yes → Push notification + SMS fallback
│   └── No → Email digest or in-app badge

Trigger Phrases

• "Add notifications"
• "Alert users when..."
• "Send email when..."
• "Push notifications for..."

Notification Types

Type	Channel	Priority	Retention
Transactional	Email + In-app	High	30 days
Marketing	Email	Low	90 days
System	In-app	Medium	7 days
Alert	Push + SMS	Critical	Until read

Implementation Patterns

Preference Schema

{
  "channels": {
    "email": { "enabled": true, "frequency": "immediate" },
    "push": { "enabled": true, "quiet_hours": ["22:00", "08:00"] },
    "sms": { "enabled": false },
    "in_app": { "enabled": true }
  },
  "types": {
    "marketing": { "enabled"  
        
        
  

Delivery Queue

class NotificationQueue {
  async enqueue(notification) {
    const prefs = await this.getUserPreferences(notification.userId);
    const channels = this.resolveChannels(notification.type, prefs);
    for (const channel of channels) {
      await this.queueChannelDelivery(notification, channel);
    }
  }
}

Batching Strategy

const batchWindow = {
  email: { duration: '1h', maxItems: 10 },
  push: { duration: '5m', maxItems: 5 },
  sms: { duration: '0', maxItems: 1 }
};
