To install the SDK, use Yarn, npm, or a script tag:

• npm

npm install @parcelvoy/js-sdk

• Yarn

yarn add @parcelvoy/js-sdk

script tag

<script src="https://unpkg.com/@parcelvoy/js-sdk/lib/esm/index.js"></script>

The SDK can be used both on the server or in the web browser. The main difference is that on the Browser the identified user will be cached vs in Node where you'll need to pass in identifiers on every request.

Before using any methods, the library must be initialized with an API key and URL endpoint.

If you aren't accessing the SDK via script tag, start by importing the Parcelvoy SDK:

// 
const { Client /** or BrowserClient */ } = require('@parcelvoy/js-sdk')

// Or
import { Client /** or BrowserClient */ } from '@parcelvoy/js-sdk'

Then you can initialize the library:

// Node
const client = new Client({
    apiKey: "XXX-XXX",
    urlEndpoint: "https://app.parcelvoy.com/api"
})

// Browser
const client = new BrowserClient({
    apiKey: "XXX-XXX",
    urlEndpoint: "https://app.parcelvoy.com/api"
})

// Or global script
Parcelvoy.initialize({
    apiKey: "XXX-XXX",
    urlEndpoint: "https://app.parcelvoy.com/api"
})

You can handle the user identity of your users by using the identify method. This method works in combination to either/or associate a given user to your internal user ID (external_id) or to associate attributes (traits) to the user. By default all events and traits are associated with an anonymous ID until a user is identified with an external_id. From that point moving forward, all updates to the user and events will be associated to your provider identifier.

// Client
client.identify({
    externalId: "XXX-XXX"
    phone: "+1234567890"
    email: "[email protected]"
    traits: {}
})

// Or global script
Parcelvoy.identify({
    externalId: "XXX-XXX"
    phone: "+1234567890"
    email: "[email protected]"
    traits: {}
})

If you want to trigger a journey and list updates off of things a user does within your app, you can pass up those events by using the track method.

// Client
client.track({
    event: "Tapped Button"
    traits: {
        "Key": "Value"
    }
})

// Or global script
Parcelvoy.track({
    event: "Tapped Button",
    traits: {
        "Key": "Value"
    }
})
