@happyvertical/smrt-analytics

Analytics integration models for the SMRT framework. Manages analytics properties (GA4, Plausible, Matomo), data streams, server-side event tracking with retry support, and AI-powered report generation with scheduling.

Installation

pnpm add @happyvertical/smrt-analytics

Usage

import {
  AnalyticsProperty, AnalyticsPropertyCollection,
  AnalyticsDataStream, AnalyticsDataStreamCollection,
  AnalyticsEvent, AnalyticsEventCollection,
  AnalyticsReport, AnalyticsReportCollection,
  AnalyticsProvider, DataStreamType, ReportFrequency
} from '@happyvertical/smrt-analytics';

// Create a GA4 property
const properties = new AnalyticsPropertyCollection(db);
const property = await properties.create({
  name: 'main-site',
  displayName: 'Main Site Analytics',
  provider: AnalyticsProvider.GA4,
  externalId: 'properties/123456789',
  measurementId: 'G-XXXXXXXXXX',
  apiSecret: 'server-side-secret',
  status: 'active',
});

// Add a web data stream
const streams = new AnalyticsDataStreamCollection(db);
await streams.create({
  propertyId: property.id,
  displayName: 'Web Traffic',
  streamType: DataStreamType.WEB,
  measurementId: 'G-XXXXXXXXXX',
  defaultUri: 'https://example.com',
  status: 'active',
});

// Track a server-side event with retry support
const events = new AnalyticsEventCollection(db);
const event = await events.create({
  propertyId: property.id,
  eventName: 'purchase',
  clientId: 'client-uuid',
  params: JSON.stringify({ value: 99.99, currency: 'USD' }),
  status: 'pending',
});
// After sending: event.markSent() or event.markFailed('timeout')
// Retry logic: event.shouldRetry(3) checks retryCount < maxRetries

// Create a scheduled report with dimensions and metrics
const reports = new AnalyticsReportCollection(db);
const report = await reports.create({
  propertyId: property.id,
  name: 'Weekly Traffic Report',
  dimensions: JSON.stringify([{ name: 'country' }, { name: 'deviceCategory' }]),
  metrics: JSON.stringify([{ name: 'activeUsers' }, { name: 'sessions' }]),
  dateRangeStart: '7daysAgo',
  dateRangeEnd: 'today',
  frequency: ReportFrequency.WEEKLY,
});

// AI-powered operations (uses do() and is() from SmrtObject)
const analysis = await property.analyzePerformance({ period: '30 days' });
const isHealthy = await property.isPerformingWell();
const insights = await report.analyzeResults();
const trending = await report.hasPositiveTrends();

Server-Side Event Lifecycle

Events track their delivery status with built-in retry support:

1. PENDING -- created, not yet sent to provider
2. SENT -- successfully delivered (markSent() sets sentAt timestamp)
3. FAILED -- delivery failed (markFailed(error) increments retryCount)

Use shouldRetry(maxRetries) to check if a failed event should be retried, and resetForRetry() to reset it to PENDING.

Report Scheduling

Reports support automatic scheduling via ReportFrequency:

• ONCE -- single run, no rescheduling
• DAILY / WEEKLY / MONTHLY -- calculateNextRun() sets nextRunAt after each run

Use isDue() to check if a scheduled report needs to run.

API

Models

Export	Description
AnalyticsProperty	GA4 property, Plausible site, or Matomo site. AI methods: analyzePerformance(), isPerformingWell()
AnalyticsDataStream	Data stream within a property (web/iOS/Android). getPlatformId() returns measurementId or firebaseAppId
AnalyticsEvent	Server-side tracking event with retry queue. toTrackEvent() builds SDK payload
AnalyticsReport	Saved report config with dimensions/metrics, scheduling, result caching. AI methods: analyzeResults(), hasPositiveTrends()

Collections

AnalyticsPropertyCollection, AnalyticsDataStreamCollection, AnalyticsEventCollection, AnalyticsReportCollection

Enums

Export	Description
AnalyticsProvider	ga4, plausible, matomo
AnalyticsPropertyStatus	active, inactive, pending
DataStreamType	WEB_DATA_STREAM, ANDROID_APP_DATA_STREAM, IOS_APP_DATA_STREAM
DataStreamStatus	active, inactive
TrackingEventStatus	pending, sent, failed
ReportStatus	draft, scheduled, running, completed, failed
ReportFrequency	once, daily, weekly, monthly
CountingMethod	ONCE_PER_EVENT, ONCE_PER_SESSION
CustomDimensionScope	EVENT, USER, ITEM

SDK Types

Re-exported from ./types for SDK compatibility: AnalyticsInterface, AnalyticsCapabilities, SDKProperty, SDKDataStream, SDKTrackEvent, SDKPageviewEvent, SDKReportOptions, SDKReportResult, SDKCustomDimension, SDKCustomMetric, SDKKeyEvent, PropertyStatsWithTrend.

Dependencies
