Implementing Privacy-Friendly Data Tracking with walker.js

Step 1: Introduction to walker.js

walker.js is an open-source library and first-party tracking solution that allows you to own the data collection process. It addresses privacy in a few ways, including allowing you to send data directly to your own endpoint.

Step 2: Setting up walker.js

To set up walker.js, you need to initialize it using the setupAnalytics() function. You can then create an elbLayer array to store all your information. walker.js also provides pre-defined triggers that you can use to track events.

const elbLayer = [];
setupAnalytics({
  // configuration options
});

Step 3: Tagging pages with walker.js

You can tag pages with walker.js using HTML attributes. For example, you can add a load trigger to track page views or a wait trigger to measure bounce rates.

<a href="#" data-walker-trigger="load">Track page view</a>
<a href="#" data-walker-trigger="wait">Measure bounce rate</a>

Step 4: Adding custom events with JavaScript

walker.js also allows you to implement custom triggers using JavaScript. You can define a new event and push it to the elbLayer using the elb helper function.

const customEvent = {
  type: 'customEvent',
  data: {
    // event data
  },
};
elb('push', customEvent);

Step 5: Implementing custom events

To implement custom events, you need to define a function that pushes the event to the elbLayer. You can then import this function in the location where you want to track the event.

function trackCustomEvent() {
  const customEvent = {
    type: 'customEvent',
    data: {
      // event data
    },
  };
  elb('push', customEvent);
}

// Import and call the function where you want to track the event
import trackCustomEvent from './trackCustomEvent';
trackCustomEvent();

The final answer is: There is no final numerical answer to this problem as it involves implementing a solution using walker.js. However, by following the steps outlined above, you can implement privacy-friendly data tracking in your application.
