JavaScript API

The widget exposes one API object under two global names that are the same reference: window.laneChat === window.laneChatSDK. Any method works on either handle.

Global	Status
window.laneChat	Canonical name. Use this.
window.laneChatSDK	Historic alias, permanently kept for backward compatibility.

Methods

Method	Returns	Description
init()	widget instance	Mount the widget. Idempotent — repeat calls reuse the existing instance.
destroy()	void	Unmount and clean up. Safe to init() again afterward.
open() / openChat()	void	Open the chat panel. Emits open. openChat is an alias of open.
close()	void	Close the chat panel. Emits close.
toggle()	void	Toggle the panel. Emits open or close per the resulting state.
isOpen()	boolean	Whether the panel is currently open.
isMounted()	boolean	Whether the widget is mounted (useful before an SPA destroy()).
updateTheme(themeConfig)	void	Update theme config at runtime.
identify(traits)	void	Set or update visitor identity and custom attributes. See Identifying visitors.
setFromData(data)	void	Alias of identify() (historic name), identical behavior.
on(event, cb)	unsubscribe fn	Subscribe to a widget event. See Events.

Lifecycle

// Mount (SPA / manual init)
window.laneChat.init()

// Is it up?
if (window.laneChat.isMounted()) {
  // safe to operate on it
}

// Tear down
window.laneChat.destroy()

init() is idempotent: repeat calls return the existing instance instead of mounting twice.

Opening and closing

window.laneChat.open()   // open the panel
window.laneChat.close()  // close it
window.laneChat.toggle() // flip based on current state

if (window.laneChat.isOpen()) {
  // panel is currently open
}

Theming at runtime

window.laneChat.updateTheme({
  // theme config fields, applied live without a remount
})

Identity

window.laneChat.identify({
  email: '[email protected]',
  name: 'Jane Doe',
  plan: 'pro',
})

See Identifying visitors for the full field and promotion contract.

Events

const off = window.laneChat.on('open', () => console.log('opened'))
off() // unsubscribe

See Events for the event list and semantics.

Additive by design

No existing method signature or behavior has changed across versions. laneChat, identify, and on are purely additive over the historic laneChatSDK / setFromData surface.
