Event handlers

All event handlers listed below are registered if provided for the first time. They unregister on the component cleanup or the property value change. Descriptions of all events are available after clicking on the associated links.

Composition API

This package exports a set of Vue Composition API utilities that allow consuming reactive data from the chat widget in any place of the application as long as the LiveChatWidget component is rendered in the tree.

The composition API is only availble for Vue 3 apps.

useWidgetState

Access the current chat widget availability or visibility state if the chat widget is loaded.

<script setup>
  import { useWidgetState } from '@livechat/widget-vue'
  const widgetState = useWidgetState()
</script>

<template>
  <div v-if="widgetState">
    <span>{{widgetState.availability}}</span>
    <span>{{widgetState.visibility}}</span>
  </div>
</template>

useWidgetIsReady

Check if the chat widget is ready using the boolean flag isWidgetReady.

<script setup>
  import { useWidgetIsReady } from '@livechat/widget-vue'
  const isWidgetReady = useWidgetIsReady()
</script>

<template>
  <div>
    <span>Chat Widget is</span>
    <span v-if="isWidgetReady">loaded</span>
    <span v-else>loading...</span>
  </div>
</template>

useWidgetChatData

Access the chatId and threadId of the chat if there's one currently available.

<script setup>
  import { useWidgetChatData } from '@livechat/widget-vue'
  const chatData = useWidgetChatData()
</script>

<template>
  <div v-if="chatData">
    <span>{{chatData.chatId}}</span>
    <span>{{chatData.threadId}}</span>
  </div>
</template>

useWidgetGreeting

Access the current greeting id and uniqueId if one is currently displayed (received and not hidden).

<script setup>
  import { useWidgetGreeting } from '@livechat/widget-vue'
  const greeting = useWidgetGreeting()
</script>

<template>
  <div v-if="greeting">
    <span>{{greeting.id}}</span>
    <span>{{greeting.uniqueId}}</span>
  </div>
</template>

useWidgetCustomerData

Access the id, isReturning, status, and sessionVariables of the current customer if the chat widget is loaded.

<script setup>
  import { useWidgetCustomerData } from '@livechat/widget-vue'
  const customerData = useWidgetCustomerData()
</script>

<template>
  <div v-if="customerData">
    <span>{{customerData.id}}</span>
    <span>{{customerData.isReturning}}</span>
    <span>{{customerData.status}}</span>
    <ul>
      <li v-for="variable in customerData.sessionVariables">{{variable}}</li>
    </ul>
  </div>
</template>

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

Vue 3

<script lang="ts" setup>
  import { LiveChatWidget } from '@livechat/widget-vue'

  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,
    }
  }

        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,
