ga-tracker v1.3.0

Google Analytics EC Wrapper

A javascript class designed to wrap google analytics enhanced e-commerce

It provides an unified api for both universal tracking and global site. It also keeps track of steps and lists automatically (uses localStorage)

Installation

Using npm

npm install ga-tracker

**or yarn

yarn add ga-tracker

and then import it in your projects

import GaTracker from 'ga-tracker'

Alternatively you can include a script tag point to the standalone version

<scrpit src="node_modules/ga-tracker/dist/ga-tracker.min.js"></scrpit>

Initialisation

Create a new instance of GaTracker and pass your analytics id as your first param

<script>
	var ga = new GaTracker('UA-456465-I')
</script>

or if using node

import GaTracker from 'ga-tracker'

const ga = new GaTracker('UA-456465-I')

By default it uses Universal Tracking if you want to use Global Site Tag set the second param to gtag

<script>
	var ga = new GaTracker('UA-456465-I', 'gtag')
</script>

or if using node

import GaTracker from 'ga-tracker'

const ga = new GaTracker('UA-456465-I', 'gtag')

If you already initialised Google analytics using either Universal Analytics or Global Site Tag leave the first param blank.

<script>
	var ga = new GaTracker(null, 'gtag')
</script>

or if using node

import GaTracker from 'ga-tracker'

const ga = new GaTracker(null, 'gtag')

Usage

I assume you know what each event does so I wont get into details about they are. I will instead show implementation examples.

Checkout

Begin

var tracker = new GaTracker()
var product1 = tracker.product({
	"id": "P12345",
	"name": "Android Warhol T-Shirt",
	"brand": "Google",
	"category": "Apparel/T-Shirts",
	"variant": "Black",
	"position": 1,
	"quantity": 1,
	"price": 2
})
var product2 = tracker.product({
	"id": "P67890",
	"name": "Flame challenge TShirt",
	"brand": "MyBrand",
	"category": "Apparel/T-Shirts",
	"variant": "Red",
	"position": 2,
	"quantity": 1,
	"price": 3
})
var checkout = tracker.checkout()
checkout
	.setItems([product1.getJson(), product2.getJson()])
	.begin()

Progress

var tracker = new GaTracker()
var product1 = tracker.product({
	"id": "P12345",
	"name": "Android Warhol T-Shirt",
	"brand": "Google",
	"category": "Apparel/T-Shirts",
	"variant": "Black",
	"position": 1,
	"quantity": 1,
	"price": 2
})
var product2 = tracker.product({
	"id": "P67890",
	"name": "Flame challenge TShirt",
	"brand": "MyBrand",
	"category": "Apparel/T-Shirts",
	"variant": "Red",
	"position": 2,
	"quantity": 1,
	"price": 3
})
var checkout = tracker.checkout()
checkout
	.setItems([product1.getJson(), product2.getJson()])
	.progress()

You can progress as many times as you need. It will keep adding steps to the checkout. In case you need to implicitly set the step pass it as a parameter on the progress method

checkout.progress(2)
