Hooks
This package exports a set of React Hooks that allows consuming reactive data from the chat widget in any place of the application as long as the LiveChatWidget
component is rendered in the tree.
useWidgetState
Access the current chat widget availability
or visibility
state if the chat widget is loaded.
import { useWidgetState } from '@livechat/widget-react'
function App() {
const widgetState = useWidgetState()
if (widgetState) {
return (
<div>
<span>{widgetState.availability}</span>
<span>{widgetState.visibility}</span>
</div>
)
}
}
useWidgetIsReady
Check if the chat widget is ready using the boolean flag isWidgetReady
.
import { useWidgetIsReady } from '@livechat/widget-react'
function App() {
const isWidgetReady = useWidgetIsReady()
return <div>Chat Widget is {isWidgetReady ? 'loaded' : 'loading...'}</div>
}
useWidgetChatData
Access the chatId
and threadId
of the chat if there's one currently available.
import { useWidgetChatData } from '@livechat/widget-react'
function App() {
const chatData = useWidgetChatData()
if (chatData) {
return (
<div>
<span>{chatData.chatId}</span>
<span>{chatData.threadId}</span>
</div>
)
}
}
useWidgetGreeting
Access the current greeting id
and uniqueId
if one is currently displayed (received and not hidden).
import { useWidgetGreeting } from '@livechat/widget-react'
function App() {
const greeting = useWidgetGreeting()
if (greeting) {
return (
<div>
<span>{greeting.id}</span>
<span>{greeting.uniqueId}</span>
</div>
)
}
}
useWidgetCustomerData
Access the id
, isReturning
, status
, and sessionVariables
of the current customer if the chat widget is loaded.
import { useWidgetCustomerData } from '@livechat/widget-react'
function App() {
const customerData = useWidgetCustomerData()
if (customerData) {
return (
<div>
<span>{customerData.id}</span>
<span>{customerData.isReturning}</span>
<span>{customerData.status}</span>
<ul>
{Object.entries(customerData.sessionVariables).map(([key, value]) => (
<li key={key}>{value}</li>
))}
</ul>
</div>
)
}
}
Custom Identity Provider
In order to make Custom Identity Provider work, you'll have to properly implement and provide a set of following methods:
getToken
- resolving Chat Widget token. If you want to cache the token, this should return the cached token instead of a fresh request to https://accounts.livechat.com/customer/token endpoint.getFreshToken
- resolving Chat Widget token. This should always make a call for a fresh token from https://accounts.livechat.com/customer/token endpoint.hasToken
- resolving boolean. It determines whether a token has been acquired.invalidate
- resolving nothing. When called, it should remove the current token. There is no need to do anything else as a new token will be requested by getFreshToken afterwards.
Example usage
import { LiveChatWidget } from '@livechat/widget-react'
const customIdentityProvider = () => {
const baseAPI = 'YOUR_API_URL'
const userId = '30317220-c72d-11ed-2137-0242ac120002'
const getToken = async () => {
const response = await fetch(`${baseAPI}/getToken/${userId}`)
const token = await response.json()
console.log('getToken', token)
return token
}
const getFreshToken = async () => {
const response = await fetch(`${baseAPI}/getFreshToken/${userId}`)
const token = await response.json()
console.log('getFreshToken, token')
return token
}
const hasToken = async () => {
const response = await fetch(`${baseAPI}/hasToken/${userId}`)
const data = await response.json()
return data
}
const invalidateToken = async () => {
const response = await fetch(`${baseAPI}/invalidate/${userId}`)
const data = await response.json()
console.log(data)
}
return {
getToken,
getFreshToken,
hasToken,
invalidate: invalidateToken,
}
}
function App() {
return (
<LiveChatWidget
license="12345678"
visibility="maximized"
customIdentityProvider={customIdentityProvider}
/>
)
}
