What are @snowplow/browser-tracker-core's main functionalities?

Initialize Tracker

This feature allows you to initialize a new Snowplow tracker instance. You need to provide a tracker namespace, the collector endpoint, and optional configuration settings such as the application ID.

const { newTracker } = require('@snowplow/browser-tracker-core');

const tracker = newTracker('sp1', 'my-collector.com', { appId: 'my-app-id' });

Track Page View

This feature enables tracking of page views. It sends an event to the collector whenever a page is viewed, which is essential for understanding user navigation and engagement.

tracker.trackPageView();

Track Custom Events

This feature allows you to track custom events by defining a self-describing event schema and data. It is useful for capturing specific user interactions that are not covered by standard event types.

tracker.trackSelfDescribingEvent({
  schema: 'iglu:com.acme/event/jsonschema/1-0-0',
  data: {
    eventCategory: 'category',
    eventAction: 'action',
    eventLabel: 'label',
    eventValue: 'value'
  }
});

Track Structured Events

This feature enables tracking of structured events, which are predefined event types with specific properties. It is useful for capturing common user interactions like clicks, form submissions, and more.

tracker.trackStructEvent({
  category: 'category',
  action: 'action',
  label: 'label',
  property: 'property',
  value: 'value'
});
