Usage

import { createTracker } from '@litemetrics/tracker';

const tracker = createTracker({
  siteId: 'your-site-id',
  endpoint: 'https://your-server.com/api/collect',
});

// Track custom events
tracker.track('Signup', { plan: 'pro' });

// Identify users
tracker.identify('user-123', { name: 'John', email: 'john@example.com' });

// Manual page tracking
tracker.page();

Auto-Tracking

When autoTrack is enabled (default), the tracker automatically captures:

Pageviews - Initial page load
SPA Navigation - Route changes via History API
Data Attributes - Clicks on data-litemetrics-event="EventName" elements
Link Clicks - Internal link clicks (path + link target path)
Outbound Links - Clicks on external links
File Downloads - Clicks on links to .pdf, .zip, .doc, .csv, etc.
Button Clicks - Button clicks (text + selector)
Scroll Depth - Milestones at 25%, 50%, 75%, 90%
Rage Clicks - 3+ rapid clicks in the same area

Auto events are tagged with eventSource=auto and an eventSubtype (e.g. scroll_depth, button_click). This makes them easy to filter in the dashboard and API. Manual track() events default to eventSource=manual and eventSubtype=custom. Older events collected before this change may have eventSource set to null.

Configuration

createTracker({
  siteId: 'your-site-id',        // Required
  endpoint: '/api/collect',       // Required
  autoTrack: true,                // Auto-track pageviews (default: true)
  autoSpa: true,                  // Auto-track SPA navigation (default: true)

Data Attribute Tracking

Track events declaratively with HTML attributes:

<button
  data-litemetrics-event="Add to Cart"
  data-litemetrics-event-product="T-Shirt"
  data-litemetrics-event-price="29.99"
>
  Add to Cart
</button>
