Usage

CommonJS Example

// Create an instance with base 64 encoding set to false (it defaults to true)
const core = trackerCore(false);

ES Module Example

import { trackerCore } from '@mailbiz/tracker-core';

// Create an instance with base 64 encoding set to false (it defaults to true)
const core = trackerCore(false)

Example

// Add a name-value pair to all payloads
core.addPayloadPair('vid', 2);

// Add each name-value pair in a dictionary to all payloads
core.addPayloadDict({
    'ds': '1160x620',
    'fp': 4070134789
});

// Add name-value pairs to all payloads using convenience methods
core.setTrackerVersion('js-3.0.0');
core.setPlatform('web');
core.setUserId('user-321');
core.setColorDepth(24);
core.setViewport(600, 400);
core.setUseragent('Mailbiz/0.0.1');

// Track a page view with URL and title
const pageViewPayload = core.track(buildPageView({ pageUrl: 'http://www.example.com', pageTitle: 'landing page'});

console.log(pageViewPayload.build());
/*
{
    'e': 'pv',
    'url': 'http://www.example.com',
    'page': 'landing page',
    'uid': 'user-321',

    },                          // timestamp
    'hash': '0718a85a-45dc-4f71-a949-27870442ed7d'  // UUID
}
*/

Other features

Core instances can be initialized with three parameters. The first is a boolean and determines whether custom contexts and unstructured events will be base 64 encoded. The second are optional Core Plugins, these can be used to intercept payload creation and add contexts on every event. The third is an optional callback function which gets applied to every payload created by the instance.

const core = trackerCore(true, [], console.log);

The above example would base 64 encode all unstructured events and custom contexts and would log each payload to the console.

Use the setBase64Encoding method to turn base 64 encoding on or off after initializing a core instance:

const core = trackerCore(); // Base 64 encoding on by default

core.setBase64Encoding(false); // Base 64 encoding is now off
