Mailberry Tracker

Mailberry Tracker is a lightweight JavaScript library for tracking user interactions and events on your website. It sends data to Mailberry's backend for processing and analysis.

Installation

Add the Mailberry tracker script to your HTML document:

<script defer id="mailberry-tracker" src="https://unpkg.com/[email protected]/build/tracker.min.js" data-customer-id="YOUR_CUSTOMER_ID"></script>

Replace YOUR_CUSTOMER_ID with the ID provided by Mailberry.

Usage

Identifying Users

Before tracking events, you should identify the current user:

mailberry.identify({
  email: '[email protected]',
  firstName: 'John',
  lastName: 'Doe',
  // Add any other user attributes
});

The identify method returns a Promise, so you can chain actions:

mailberry.identify({ email: '[email protected]' }).then(() => {
  // Continue with tracking events
});

Tracking Events

Use the track method to record user interactions:

mailberry.track('purchase', {
  productId: 'prod-123',
  price: 99.99,
  currency: 'USD'
});

The first parameter is the event type (e.g., 'purchase', 'click', 'pageview'), and the second is an object containing event data.

Using the Push Method

The push method allows you to queue commands for execution:

mailberry.push(['track', 'Started Checkout', { cartValue: 150 }]);

Push accepts an array with the following format:

• First element: command name ('track' or 'identify')
• Second element: event type (for 'track') or user info (for 'identify')
• Third element: event data (for 'track') or callback function (for 'identify')

Examples

Basic Page View Tracking

document.addEventListener('DOMContentLoaded', function() {
  mailberry.identify({ email: '[email protected]' }).then(() => {
    mailberry.track('pageview', { page: window.location.pathname });
  });
});

E-commerce Purchase Tracking

function trackPurchase(orderId, items, total) {
  mailberry.track('purchase', {
    orderId: orderId,
    items: items,
    totalAmount: total,
    currency: 'USD',
    timestamp: new Date().toISOString()
  });
}

Form Submission Tracking

document.getElementById('contact-form').addEventListener('submit', function() {
  mailberry.track('form_submit', {
    formId: 'contact-form',
    formName: 'Contact Us'
  });
});

Advanced Configuration

Error Handling

All methods return Promises, so you can handle errors:

mailberry.track('event', data)
  .then(response => {
    console.log('Event tracked successfully');
  })
  .catch(error => {
    console.error('Error tracking event:', error);
  });

Automatic Retries

The tracker automatically saves failed events to localStorage and retries sending them when possible.
