@chordcommerce/analytics

The @chordcommerce/analytics library provides simple methods for sending tracking events to Chord from your website, with an optional debugging mode to validate event properties.

@chordcommerce/analytics is intended to be installed alongside a customer data platform (CDP) tracking library like Segment's analytics.js. @chordcommerce/analytics sends Chord tracking events to the CDP tracking library, so they’re available for all connected integrations.

Visit docs.chord.co for guides, examples, and an API reference.

Requirements

A CDP Javascript library must be installed in your project. Currently, only Segment's analytics.js library is supported.

Installation

To install @chordcommerce/analytics, run the following command in your project directory:

npm install @chordcommerce/analytics
# or
yarn add @chordcommerce/analytics

Usage

First, ensure that a CDP Javascript library is installed and configured in your project. Then, initialize @chordcommerce/analytics as follows:

import ChordAnalytics from '@chordcommerce/analytics'

const chord = new ChordAnalytics(options) // see below for configuration options

chord.trackCartViewed({ cart }) // sends a "Cart Viewed" event to the CDP

Configuration

@chordcommerce/analytics can be initialized with the following options:

Property	Required	Description
cdp	true	A reference to the CDP library, or a function that returns a reference to the CDP library. For example, if using Segment's analytics.js library, this could be window.analytics or () => window.analytics. If omitted, no tracking events are sent.
debug	false	Defaults to false. When set to true, events are validated against Chord's tracking plan and errors are logged. We recommend enabling this for development and disabling for production.
enableLogging	false	Defaults to true. When set to true, errors are logged using console.log.
formatters	true	Functions that are used to construct tracking events. There are two types of formatters, objects and events. formatters.objects is required. See below for details.
metadata	true	Event metadata. See below for details.
stripNull	false	Defaults to true. When set to true, event properties with a null value are removed. CDPs typically treat null and undefined as separate values, so be sure you intend to send null values before setting to false.

Metadata

Property	Required	Description
metadata.i18n.currency	true	The order currency in ISO 4217 currency code, uppercase. For example, USD.
metadata.i18n.locale	true	The order locale. For example, en-US.
metadata.ownership.omsId	true	A UUID assigned by Chord.
metadata.ownership.storeId	true	A UUID assigned by Chord.
metadata.ownership.tenantId	true	A UUID assigned by Chord.
metadata.platform.name	true	The e-commerce platform used. For example, Shopify.
metadata.platform.type	true	The type of platform where the event originated. Either web or pos.
metadata.store.domain	true	The domain of the site where the event originated. For Shopify, this should be the store slug that comes before .myshopify.com.

Formatters

Formatters are Javascript functions that are used to construct tracking event properties. There are two types of formatters, objects and events. You must define object formatters. Event formatters are optional. See Chord’s documentation for more details and example formatters.

Object Formatters

A formatter must be provided for each of the four core data types that are used in Chord events. This formatter function transforms input data into the type Chord expects. See Chord’s documentation for more details on object formatters.

Property	Required	Description
formatters.objects.cart	true	A function that creates a cart object.
formatters.objects.checkout	true	A function that creates a checkout object.
formatters.objects.lineItem	true	A function that creates a line item object.
formatters.objects.product	true	A function that creates a product object.

Event Formatters

A formatter can be provided for each event. This formatter is used to transform the event properties of a specific event after Chord constructs the event, just before it's sent to the CDP. See Chord’s documentation for more details on event formatters.

Using with Typescript

Optionally, you can instantiate ChordAnalytics with a custom type argument describing your data to improve type safety for formatters and SDK functions.

For instance, if you're working with objects like cart, product, etc., from a Shopify storefront API query, you might already have types like StorefrontCart defined for the response. Instantiate ChordAnalytics with a type argument:

interface ObjectTypes {
  Cart: StorefrontCart
  Checkout: StorefrontCart
  LineItem: StorefrontLineItem
  Product: StorefrontProduct
}

const chord = new ChordAnalytics<ObjectTypes>({ options })

Now, when you use an SDK method like chord.trackCartViewed({ cart }), cart has the StorefrontCart type.

Formatter types also support an optional generic type parameter for the function argument:

import type { CartFormatter } from '@chordcommerce/analytics'

export const cartFormatter: CartFormatter<StorefrontCart> = (props) => {
  const { cart } = props // `cart` has type `StorefrontCart`
  return { ... }
}
