Hellotext.js

Official Hellotext JavaScript library.

This library allows you the following,

• Track events happening on your site to Hellotext in real-time.
• Use Hellotext Forms to dynamically collect data from your customers based on your specific business requirements.
• Use Hellotext Webchat to interact with your customers in real-time.
• Let visitors subscribe and unsubscribe to browser notifications with Push notifications.

Installation

Using NPM

npm i @hellotext/hellotext

Using yarn

yarn add @hellotext/hellotext

Configure

Import the library into your app.

import Hellotext from '@hellotext/hellotext'

If you're running in a non-browser environment, such as Node.js, you can import the vanilla implementation which only includes Hellotext.js class without initializing other libraries that rely on the browser environment.

import Hellotext from '@hellotext/hellotext/vanilla'

Initialize the library passing the public HELLOTEXT_BUSINESS_ID identifier that represents the business.

You can find it from the business's settings page.

Hellotext.initialize('HELLOTEXT_BUSINESS_ID')

Failing to initialize the class before calling any other method will throw a NotInitializedError.

Events

Use Hellotext.on to listen for SDK events. The callback receives the event's payload directly. Register listeners before Hellotext.initialize to receive events emitted during initialization.

Hellotext.on(eventName, callback)

To unsubscribe, pass the same callback to Hellotext.removeEventListener:

Hellotext.removeEventListener(eventName, callback)

Sessions and attribution

Event	When it fires	Callback payload
session-set	The session value is set, including when an existing session is restored during initialization.	The current session value, also available as Hellotext.session.
utm-set	UTM parameters are saved.	A JSON string containing the saved UTM parameters and observed_at. Use JSON.parse to read it as an object.

See Understanding Sessions and Tracking Events.

Forms

Event	When it fires	Callback payload
forms:collected	Forms found on the page have finished loading, before automatic mounting.	The FormCollection instance, with methods such as getById, getByIndex, and forEach.
form:completed	A form completes, or a previously completed form is restored from local storage during mounting.	{ id, state, data, completedAt }, where data contains the submitted values and completedAt is a timestamp in milliseconds.

See Forms for collection, mounting, and completion details.

Smart Alerts

Each alert event receives { kind }, where kind identifies the section: homepage, product_collection, or product_details.

Event	When it fires	Callback payload
alert:shown	A section is displayed by a successful show call, including forced calls.	{ kind }
alert:dismissed	The visitor clicks the secondary action, hiding the alert and starting its dismissal cooldown.	{ kind }
alert:accepted	The visitor clicks the primary action, before the browser permission result or subscription completion.	{ kind }

alert:accepted does not confirm that the visitor granted permission or subscribed. Programmatic hiding, cleanup, and dismissals received from another tab do not emit alert:dismissed.

Hellotext.on('alert:accepted', ({ kind }) => {
  console.log('Alert accepted in', kind)
})

See Smart Alerts for display options and dismissal behavior.

Webchat

Event	When it fires	Callback payload
webchat:mounted	The Webchat widget is mounted.	None.
webchat:opened	The Webchat conversation opens.	None.
webchat:closed	The Webchat conversation closes.	None.
webchat:message:sent	A visitor's message or quick reply is successfully sent.	The message object, including id, body, and attachments, with additional context for quick replies and product cards.
webchat:message:received	An incoming message is added to the Webchat conversation.	The message object, with body containing its displayed text.

See Webchat events for message payload examples.

Cart

Event	When it fires	Callback payload
cart.added	The visitor clicks an add-to-cart button in a Webchat product card.	{ object_parameters: { items }, source }. Each item contains product, quantity, and optional reference and source; the outer source contains kind, message_id, and button_id.

Handle cart.added in your storefront integration to update the cart. This event records the button click; it does not confirm that your storefront added the item successfully.

Hellotext.initialize('HELLOTEXT_BUSINESS_ID', configurationOptions)
