Snap Tracker

The Snap Tracker service is responsible for sending beacon events.

Dependencies

Snap Tracker is a dependency of @searchspring/snap-controller

Installation

npm install --save @searchspring/snap-tracker

Import

import { Tracker } from '@searchspring/snap-tracker';

Tracker Config

| option | description | default value | required | |---|---|:---:|:---:| | id | unique identifier for the tracker | track | | | framework | unique identifier for the framework utilizing the tracker | snap | | | mode | application mode (production, development) | production | | | doNotTrack | array of DoNotTrackEntry objects, used to block specific types of tracking | ➖ | |

Controller usage

Snap Tracker is a dependency of Snap Controller and Tracker events can be invoked via the tracker reference of any Snap Controller.

const globals = { siteId: 'abc123' };
const tracker = new Tracker(globals);
const controller = new SearchController(config, {
    ...
    tracker,
    ...
});

console.log(tracker.track.product.click === controller.tracker.track.product.click) // true
console.log(tracker.track.product.click === window.searchspring.tracker.track.product.click) // true

Standalone usage

Snap Tracker can also be used without a Snap Controller. Typically used to send events before an integration has gone live.

const tracker = new Tracker();
const payload = {
    type: BeaconType.CLICK,
    category: BeaconCategory.INTERACTION, 
    event: {
        intellisuggestData: '37d5578e1d1646ac97701a063ba84777',
        intellisuggestSignature: '5739a2596d3b4161b041ce1764ffa04d',
        href: '/product123'
    }
};
tracker.track.event(payload)

Tracking Events with DomTargeter

As an alternative method for tracking events, the Tracker utilizes the DomTargeter to look for script tags on the current page. These script tags must have a specific type attribute and data contents for the tracking to be used. These tracking script blocks ensure tracking events are sent when using asynchronous script execution and must be on the page prior to the DOMContentLoaded event to be picked up by initial targeting. If the script blocks are added after this event, the retarget method must be invoked.

retarget method

This method will call the retarget method on all DomTargeters set in the Tracker. Typically this would be used when new tracking script blocks have been added to the page after initial targeting.

track methods

The Tracker object is exposed to the browser's window via the first Snap Controller that has been instantiated. This will use the siteId that has been provided to the Snap Tracker instance of the respective Controller Services. The Tracker contains various tracking methods available on the track object within it.

window.searchspring.tracker.track

Each tracking method expects a data object which contains different attributes depending on the method.

tracker.track.product.view({
    uid: '123',
    sku: 'product123',
    childUid: '123_a',
    childSku: 'product123_a',
});

If a bundle is using multiple Snap Controllers with different siteId, an optional siteId parameter can be specified to overwrite any event siteId

tracker.track.product.view({
    uid: '123',
    sku: 'product123',
    childUid: '123_a',
    childSku: 'product123_a',
}, 'abc123');

Generic Event track.event

Creates and sends a generic beacon event. Parameter expects an Event Payload object. If a type or category is not provided, a value of 'custom' will be used.

const payload = {
    type: BeaconType.CLICK,
    category: BeaconCategory.INTERACTION, 
    event: {
        intellisuggestData: '37d5578e1d1646ac97701a063ba84777',
        intellisuggestSignature: '5739a2596d3b4161b041ce1764ffa04d',
        href: '/product123'
    }
};
tracker.track.event(payload)

Event Payload

A beacon event payload object provided to the track.event method may contain the following:

type - BeaconType enum value or custom event type value. If not specified, 'custom' will be used.

category - BeaconCategory enum value or custom event type value. If not specified, 'custom' will be used.

event - object containing event data

context.website.trackingCode - optional context object that will be merged with constructed context object. Can be used to specify a different siteId value.

context.currency.code - optional context object that will be merged with constructed context object. Can be used to specify a different currency value.

const payload = {
    type: BeaconType.CLICK,
    category: BeaconCategory.INTERACTION,
    event: {
        intellisuggestData: '37d5578e1d1646ac97701a063ba84777',
        intellisuggestSignature: '5739a2596d3b4161b041ce1764ffa04d',
        href: '/product123',
    },
    context: {
        website: {
            trackingCode: 'abc123',
        },
        currency: {
            code: 'USD',
        },
    },
};

Error Event track.error

Tracks error events. Parameter expects a payload with various properties derived from an ErrorEvent object. Requires at least a stack or message to be provided.

const handleErrorTracking = (event: ErrorEvent) :void => {
    const { filename, colno, lineno, error: { stack }, message, timeStamp } = event;
    const userAgent = navigator.userAgent;
    const href = window.location.href;

    const beaconPayload: TrackErrorEvent = {
        userAgent,
        href,
        filename,
        stack,
        message,
        colno,
        lineno,
        errortimestamp: timeStamp,
    };

    tracker.track.error(beaconPayload);
}

Product Click track.product.click

Tracks product click events. It is reccomended to invoke on each product onmousedown event via the result.track.click() method. Various Snap controllers will expose these tracking events differently, see the controller documentation for details.

searchController.store.results.map(result)=>{(
    <a href={core.url} onMouseDown={(e)=>{searchController.track.product.click(e, result)}}>
)}

If invoking directly, the intellisuggestData and intellisuggestSignature values are returned from SearchSpring's Search API on each result.attributes object. An optional href value can also be provided.

import { SearchController } from '@searchspring/snap-controller';
import { Tracker } from '@searchspring/snap-tracker';
const searchController = new SearchController({
    ...
    tracker: new Tracker(),
    ...
}):

tracker.track.product.click({
    intellisuggestData: '37d5578e1d1646ac97701a063ba84777',

    ud: '123',
    sku: 'product123',
    childUid: '123_a',
    childSku: 'product123_a',
});

Shopper Login track.shopper.login

Tracker properties

globals property

When constructing an instance of Tracker, a globals object is required to be constructed. This object contains a siteId key and value. An optional currency object with a code property containing a string can be provided.

const globals = { siteId: 'abc123', currency: { code: 'EUR' } };
const tracker = new Tracker(globals);
console.log(tracker.globals === globals) // true

localStorage property

A reference to the StorageStore object for accessing Tracker local storage.

const tracker = new Tracker();
tracker.localStorage.set('key', 'value')
tracker.localStorage.get('key') // 'value'

context property

The context property is generated at the time of instantiating Tracker. It is part of each event payload and provides context of the event.

userId - unique ID to identify the user, persisted in a cookie/local storage fallback

pageLoadId - unique ID generated at the time of instantiating Tracker

sessionId - unique ID generated at the start of a new browser session, persisted in session storage/cookie fallback

shopperId - unique ID provided set via the SearchController SearchController.tracker.track.shopper.login event and then persisted in a cookie

website.trackingCode - the siteId specified in the globals object

currency.code - the optional currency specified in the globals object

context: {
    userId: '0560d7e7-148a-4b1d-b12c-924f164d3d00',
    pageLoadId: 'cfb75606-c15b-4f25-a711-9de2c5d22660',
    sessionId: 'f4b25c96-9ca1-4ac6-ad04-f5ce933f8b61',
    shopperId: 'shopper0001',
    website: {
        trackingCode: 'abc123',
    },
    currency: {
        code: 'USD',
    },
}

isSending property

The isSending property contains the return value from setTimeout and when defined, signifys that an event is being sent to the beacon endpoint. If subsequent events are invoked and isSending is still defined, the incoming event will be added to the event queue to be sent at a later time.

namespace property

The namespace property contains the Tracker namespace. Invoking this method is only required if a bundle contains multiple Tracker instances.

track property

The track property contains various tracking events. See track methods section above.

setCurrency method

Sets the currency code on the tracker context.

const tracker = new Tracker();

tracker.setCurrency({ code: 'EUR' })

getUserId method

Returns an object containing the userId stored in the ssUserId cookie (with a fallback to localstorage.) If key doesn't exist, a new ID will be generated, saved to cookie/localstorage, and returned.

const tracker = new Tracker();

console.log(tracker.getUserId()) 
// { userId: '0560d7e7-148a-4b1d-b12c-924f164d3d00' }

getSessionId method

Returns an object containing the sessionId stored in the ssSessionIdNamespace session storage (with a fallback to cookies.) If key doesn't exist, a new ID will be generated, saved to session storage/cookie, and returned.

const tracker = new Tracker();

console.log(tracker.cookies.cart.get()) 
// ['sku1', 'sku2']

cookies.cart.add method

Provides a means of adding cart products to the ssCartProducts cookie.
