Enhanced Analytics Implementation Summary

✅ Completed Implementation

1. Database Schema (Migration: 20251214025341)

Status: ✅ Migrated successfully

Added 18 new columns to clicks table:

  • Geolocation (8 fields): city, region, country_name, postal_code, latitude, longitude, timezone, (existing: country)
  • Device Detection (4 fields): device_type, is_mobile, is_tablet, is_desktop, is_bot
  • Browser/OS (4 fields): browser, browser_version, os, os_version

Added 8 performance indexes:

  • Single column: city, region, country_name, device_type, is_mobile, is_bot
  • Composite: [link_id, created_at], [device_type, created_at]

2. Click Model Enhancement

File: app/models/click.rb Status: ✅ Complete

New Scopes (15 total):

Click.mobile              # Mobile device clicks
Click.desktop             # Desktop clicks
Click.tablet              # Tablet clicks
Click.bots                # Bot/crawler traffic
Click.human_traffic       # Exclude bots
Click.qr_scans            # QR code scans
Click.direct_clicks       # Direct link clicks
Click.by_country(name)    # Filter by country
Click.by_city(name)       # Filter by city
Click.by_region(name)     # Filter by region
Click.by_device_type(type) # Filter by device type
Click.recent              # Last 100 clicks
Click.today               # Today's clicks

Click.this_month          # This month's clicks

New Instance Methods:

click.qr_scan?            # Boolean: was this a QR scan?
click.mobile_device?      # Boolean: mobile or tablet?
click.location            # Hash with lat/long/city/region/country

3. LinksController Updates

File: app/controllers/api/v1/links_controller.rb Status: ✅ Complete

New Actions:

  • analytics - Comprehensive analytics endpoint with date range filtering

Updated Actions:

  • log_click - Now extracts and passes CloudFront headers to ClickJob

New Private Methods:

  • extract_cloudfront_headers - Extracts 14 CloudFront headers for geolocation and device detection

4. ClickJob Refactoring

File: app/jobs/click_job.rb Status: ✅ Complete

Removed:

  • ❌ rest-client dependency
  • ❌ ipapi.co API calls (no more rate limits!)
  • ❌ fetch_country method

Added:

  • ✅ CloudFront headers parameter (6th parameter)
  • ✅ Comprehensive User-Agent parsing
  • ✅ Bot detection (12 patterns)
  • ✅ Browser detection (Chrome, Safari, Firefox, Edge, Opera)
  • ✅ OS detection (Windows, macOS, iOS, Android, Linux)
  • ✅ Device type determination with fallbacks

New Methods:

parse_user_agent(ua)           # Parse User-Agent string
bot?(ua)                       # Detect bot/crawler
extract_browser_info(ua)       # Extract browser & version
extract_os_info(ua)            # Extract OS & version
windows_version(nt)            # Map NT version to friendly name
determine_device_type(...)     # Determine primary device type
default_user_agent_data        # Default values for missing data

5. API Endpoints

File: config/routes.rb Status: ✅ Complete

New Route:

GET /api/v1/links/:lookup_code/analytics

Query Parameters:

  • start_date (optional): YYYY-MM-DD format, defaults to 30 days ago
  • end_date (optional): YYYY-MM-DD format, defaults to today

Authentication: Required (JWT)

🔄 Data Flow

With CloudFront (Full Features)

User clicks link
    ↓
CloudFront adds geolocation/device headers
    ↓
Elastic Beanstalk receives request
    ↓
LinksController extracts CloudFront headers
    ↓
ClickJob receives cloudfront_headers + user_agent
    ↓
Database stores 18 analytics fields
    ↓
Analytics API returns rich insights

Without CloudFront (Fallback Mode)

User clicks link
    ↓
Elastic Beanstalk receives request
    ↓
LinksController passes empty cloudfront_headers
    ↓
ClickJob parses User-Agent for browser/OS/device
    ↓
Database stores partial analytics (no geolocation)
    ↓
Analytics API returns available insights

🚀 Next Steps

Option 1: Deploy to Production

git add .
git commit -m "Add enhanced analytics with CloudFront headers"
git push origin develop
eb deploy thin-ly-prod

Option 2: Set Up CloudFront (Required for Geolocation)

  1. Create CloudFront distribution in AWS Console
  2. Set origin to Elastic Beanstalk environment URL
  3. Create origin request policy with required headers:
    • CloudFront-Viewer-Country
    • CloudFront-Viewer-Country-Name
    • CloudFront-Viewer-City
    • CloudFront-Viewer-Country-Region-Name
    • CloudFront-Viewer-Postal-Code
    • CloudFront-Viewer-Latitude

    • CloudFront-Is-Desktop-Viewer
    • CloudFront-Is-Android-Viewer
    • CloudFront-Is-IOS-Viewer
    • CloudFront-Is-SmartTV-Viewer
  4. Update DNS records to point to CloudFront

Option 3: Test the API

# Get analytics for a link
curl -X GET "http://localhost:3000/api/v1/links/abc1234/analytics?start_date=2025-01-01" \
  -H "Authorization: Bearer YOUR_JWT_TOKEN"

# Get link details with enhanced clicks
curl -X GET "http://localhost:3000/api/v1/links/abc1234" \
  -H "Authorization: Bearer YOUR_JWT_TOKEN"
