What is Analytics?

Cross-project, connected user tracking events with A/B testing features

Installation

To install the package, run the following command:

$ npm i @deriv/analytics

To proper initialisation of the package, pass proper keys in special function in special for init functions place:

Analytics?.initialise({
    growthbookKey: process.env.GROWTHBOOK_CLIENT_KEY, // optional key to enable A/B tests
    growthbookDecryptionKey: process.env.GROWTHBOOK_DECRYPTION_KEY, // optional key to enable A/B tests
    // mandatory key to enable userevent tracking
    rudderstackKey: RUDDERSTACK_KEY,
})

To make good strategy for A/B testing we need to create some condition depends on data:

Analytics?.setAttributes({
    user_language: getLanguage(),
    device_language: navigator?.language,
    country: this.country,
})

And you finally can use the tracking events and A/B testing features

Usage

To start using it, let's observe on SDK usage examples:

import { Analytics } from '@deriv/analytics';

// Tracking features:
Analytics?.identifyEvent() // inentify the user
Analytics?.pageView() // track that page is showed for user
const user_id = Analytics?.getId() // get an user anon or real id


// Track Event
Analytics?.trackEvent('ce_virtual_signup_form', {
    action: 'open',
    form_name: 'default_diel_deriv',
    form_source: document?.referrer,
    signup_provider: 'email',
})

// the same as example below, to not to add repetable properties again and again
const analyticsData: Parameters<typeof Analytics.trackEvent>[1] = {
    form_name: 'default_diel_deriv',
}
Analytics?.trackEvent('ce_virtual_signup_form', {
    action: 'open',
    signup_provider: 'email',
    ...analyticsData
})
Analytics?.trackEvent('ce_virtual_signup_form', {
    action: 'close',
    signup_provider: 'google',
    ...analyticsData
})

// A/B testing features
const test_toggle_aa_test = Analytics?.getFeatureState('test-toggle-aa-test') // returns value of experiment
const common_test = Analytics?.getFeatureValue('common-test', 'fallback') // returns feature flag's boolen

If you need to get entire instance directly:

const { ab, tracking } = Analytics?.getInstances()

If you want to check your ID

window.getMyId()
