Examples

​
Track Custom Event

// Track a simple event
base44.analytics.track({
  eventName: "button_clicked"
});

// Track event with properties
base44.analytics.track({
  eventName: "purchase_completed",
  properties: {
    product_id: "prod-123",
    amount: 99.99,
    currency: "USD"
  }
});

​
Track User Actions

// Track page view
base44.analytics.track({
  eventName: "page_view",
  properties: {
    page: "/dashboard",
    referrer: document.referrer
  }
});

// Track feature usage
base44.analytics.track({
  eventName: "feature_used",
  properties: {
    feature: "export_data",
    format: "csv"
  }
});

​
Automatic Tracking

The analytics module automatically tracks:
  • Initialization events: When the app loads
  • Heartbeat events: Periodic activity signals
  • Session duration: Time spent in the app
These internal events help measure user engagement without manual instrumentation.

​
Best Practices

  1. Use descriptive event names: order_completed instead of click
  2. Include relevant properties: Add context that helps analyze the event
  3. Be consistent: Use the same event names and property keys across your app
  4. Don’t track sensitive data: Avoid PII in event properties
// Good: Descriptive with relevant properties
base44.analytics.track({
  eventName: "subscription_started",
  properties: {
    plan: "pro",
    billing_cycle: "annual"
  }
});

// Avoid: Vague event name, no context
base44.analytics.track({
  eventName: "click"
});
