Segment Wrapper

This package adds an abstraction layer on top of segment.com's JavaScript library with some useful integrations and fixes:

Data Quality 📈

• [x] Add page method that internally uses track but with the correct referrer property.
• [x] Send user.id and anonymousId on every track.

Consent Management Platform 🐾

• [x] Automatic tracking of Consent Management Platform usage.
• [x] Send gdpr_privacy on context for for all tracking events. Expect values: unknown, accepted and declined.
• [x] Send gdpr_privacy_advertising on context for for all tracking events. Expect values: unknown, accepted and declined.
• [x] gdpr_privacy is accepted when consents [1, 8, 10] are accepted and gdpr_privacy_advertising is accepted when consents [3] is accepted.
• [x] Any track is sent if the user has not accepted/rejected any consent yet.

Developer Experience 👩‍💻

• [x] Always send platform property as web.
• [x] Allow to configure window.__mpi.defaultContext to send these properties on all tracks inside the context object.
• [x] Allow to configure window.__mpi.defaultProperties to send these properties on all tracks.

Segment Middlewares 🖖

• [x] Optimizely Full Stack middleware to use Segment's anonymousId as Optimizely's userId, more info here.

Usage

After adding your Segment snippet into your html, you'll need to include this package in order to be able to fire events.

analytics will be an object with the methods described here.

Step 1: Copy the Snippet in your HTML

<script>
  !(function () {
    var analytics = (window.analytics = window.analytics || [])
    if (!analytics.initialize)
      if (analytics.invoked) window.console && console.error && console.error('Segment snippet included twice.')
      else {
        analytics.invoked = !0
        analytics.methods = [
          'trackSubmit',
          'trackClick',
          'trackLink',
          'trackForm',
          'pageview',
          'identify',
          'reset',
          'group',
          'track',
          'ready',
          'alias',
          'debug',
          'page',
          'once',
          'off',
          'on',
          'addSourceMiddleware',
          'addIntegrationMiddleware',
          'setAnonymousId',
          'addDestinationMiddleware'
        ]
        analytics.factory = function (e) {
          return function () {
            var t = Array.prototype.slice.call(arguments)
            t.unshift(e)
            analytics.push(t)
            return analytics
          }
        }
        for (var e = 0; e < analytics.methods.length; e++) {
          var key = analytics.methods[e]
          analytics[key] = analytics.factory(key)
        }
        analytics.load = function (key, e) {
          var t = document.createElement('script')
          t.type = 'text/javascript'
          t.async = !0
          t.src = 'https://cdn.segment.com/analytics.js/v1/' + key + '/analytics.min.js'
          var n = document.getElementsByTagName('script')[0]
          n.parentNode.insertBefore(t, n)
          analytics._loadOptions = e
        }
        analytics._writeKey = 'YOUR_WRITE_KEY'
        analytics.SNIPPET_VERSION = '4.13.2'

        analytics.load('YOUR_WRITE_KEY') // your write key must be set here
      }
  })()
</script>

Step 2: Use

In your modern and beautiful JavaScript...

import analytics from '@s-ui/segment-wrapper'

In your monolithic JavaScript...

// First load the UMD module.
<script src="https://unpkg.com/@s-ui/segment-wrapper/umd/index.js"></script>
<script>
  // Then trigger all the events you need referencing the right namespaced
  // object: `window.sui.analytics`. For more info see the "Events" section below.
  window.sui.analytics.identify('your user id', {});
  window.sui.analytics.track('your event', {});
  window.sui.analytics.reset();
</script>

Step 3: Configure Segment Wrapper (optional)

You could put a special config in a the window.__mpi to change some behaviour of the wrapper. This config MUST somewhere before using the Segment Wrapper.

• defaultContext: (optional) If set, properties will be merged and sent with every track and page in the context object. It's the ideal place to put the site and vertical info to make sure that static info will be sent along with all the tracking.
• defaultProperties: (optional) If set, properties will be merged and sent with every track and page.
• tcfTrackDefaultProperties (optional) If set, this property will be merged together with the default properties set to send with every tcf track event
• universalId: (optional) If set this value will be used for the Visitor API and other services.
• hashedUserEmail: (optional) If set and not universalId is set this value will be used for the Visitor API and other services.
• userEmail: (optional) If set and not universalId is available, this value will be hashed with SHA-256 and used for the Visitor API and other services.
• isUserTraitsEnabled: (optional) If set context traits will be populated with all user traits.
• userIdPrefix: (optional) If set, the user id will be prefixed with this string for identify events.

Example:

window.__mpi = {
  segmentWrapper: {
    universalId: '7ab9ddf3281d5d5458a29e8b3ae2864',
    defaultContext: {
      site: 'patinetes',
      vertical: 'motor'
    },
    tcfTrackDefaultProperties: {
      tcfSpecialProp: 'anyvalue'
    }
  }
}

It also provides additional information such as:

• window.__mpi.isFirstVisit: boolean - true if the user hasn't interacted with the tcf modal yet

Events

Track - docs

import analytics from '@s-ui/segment-wrapper'

analytics.track('CTA Clicked')

analytics.track('Registered', {
  plan: 'Pro Annual',
  accountType: 'Facebook'
})

Page

Internally uses Track but changes the referrer everytime is called.

import analytics from '@s-ui/segment-wrapper'

analytics.page('Home Viewed')

analytics.page('List Viewed', {
  property: 'HOUSE',
  transaction: 'SELL'
})

Identify - docs

import analytics from '@s-ui/segment-wrapper'

analytics.identify('97980cfea0067', {
  name: 'Peter Gibbons',
  email: '[email protected]',
  plan: 'premium',
  logins: 5
})

Reset - docs

import analytics from '@s-ui/segment-wrapper'

analytics.reset()

UniversalID

Segment Wrapper is handling all about the UniversalID, an ID to identify the user across different sites by using a hashed email. If you want, you could subscribe yourself to an event in order to retrieve this info:

document.addEventListener(USER_DATA_READY_EVENT, e => {
  const {universalId} = e.detail
})

Also, you could check directly if the universalId is already available on the window:

const {universalId} = window.__mpi.segmentWrapper

Or use both systems:

let {universalId, universalIdInitialized} = window.__mpi.segmentWrapper

if (!universalId && !universalIdInitialized) {
  document.addEventListener(USER_DATA_READY_EVENT, e => {
    universalId = e.detail.universalId
    doSomethingWithUniversalId(universalId)
  })
}

console.log(universalId)

Send xandrId as externalIds

To not send the xandrId put this flag as configuration: window.__mpi.segmentWrapper.sendXandrId = false

By default, all xandrId will be sent.

Middlewares

You can find info about segment's middleware here

Optimizely's userId

Will use segment's anonymousId as optimizely's userId

How to

import {optimizelyUserId} from '@s-ui/segment-wrapper/lib/middlewares/source/optimizelyUserId'

window.analytics.ready(() => {
  window.analytics.addSourceMiddleware(optimizelyUserId)
})

Optimizely's site attribute

Will add the site property as optimizely attribute

How to

import {optimizelySiteAttributeMiddleware} from '@s-ui/segment-wrapper/lib/middlewares/destination/optimizelySiteAttribute'

window.analytics.ready(() => {
  window.analytics.addDestinationMiddleware('Optimizely', [optimizelySiteAttributeMiddleware])
})
