This library allows to render and interact with the LiveChat Chat Widget inside an Angular application.
Using npm:
npm install @livechat/widget-angular
or using yarn:
yarn add @livechat/widget-angular
// app.module.ts
import { NgModule } from '@angular/core'
import { LiveChatWidgetModule } from '@livechat/widget-angular'
@NgModule({
/* ... */
imports: [LiveChatWidgetModule],
})
export class AppModule {}
// app.component.ts
import { Component } from '@angular/core'
import { EventHandlerPayload } from '@livechat/widget-angular'
@Component({
/* ... */
templateUrl: './app.component.html',
})
export class AppComponent {
handleNewEvent(event: EventHandlerPayload<'onNewEvent'>) {
console.log('LiveChatWidget.onNewEvent', event)
}
}
<!-- app.component.html -->
<livechat-widget
license="12345678"
visibility="maximized"
(onNewEvent)="handleNewEvent($event)"
></livechat-widget>
All properties described below are used for initialization on the first render and later updates of the chat widget with new values on change.
Prop | Type |
---|---|
license | string (required) |
customerName | string |
group | string |
customerEmail | string |
chatBetweenGroups | boolean |
sessionVariables | Record<string, string> |
visibility | 'maximized' | 'minimized' | 'hidden' |
customIdentityProvider | () => CustomerAuth |
CustomerAuth:
parameters | type | description |
---|---|---|
getFreshToken | () => Promise | Should resolve with freshly requested customer access token. |
getToken | () => Promise | Should resolve with currently stored customer access token. |
hasToken | () => Promise | Should resolve with a boolean value representing if a token has been already acquired. |
invalidate | () => Promise | Should handle token invalidation and/or clearing the locally cached value. |
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.
- onReady
- onAvailabilityChanged
- onVisibilityChanged
- onCustomerStatusChanged
- onNewEvent
- onFormSubmitted
- onRatingSubmitted
- onGreetingDisplayed
- onGreetingHidden
- onRichMessageButtonClicked
The LiveChatWidgetModule
, exported from this package, registers a set of injectable services. All of them expose a subscribable BehaviorSubject instance. It 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.
Access the current chat widget availability
or visibility
state if the chat widget is loaded.
// app.component.ts
import { Component, OnInit } from '@angular/core'
import {
WidgetStateService,
WidgetStateSubject,
} from '@livechat/widget-angular'
@Component({
/* ... */
templateUrl: './app.component.html',
})
export class AppComponent implements OnInit {
widgetState$: WidgetStateSubject
constructor(widgetStateService: WidgetStateService) {
this.widgetState$ = widgetStateService.subject
}
ngOnInit() {
this.widgetState$.subscribe((widgetState) => {
console.log('AppComponent.ngOnInit.widgetState', widgetState)
})
}
}
<!-- app.component.html -->
<div *ngIf="widgetState$ | async as widgetState">
<div>{{ widgetState.availability }}</div>
<div>{{ widgetState.visibility }}</div>
</div>
Check if the chat widget is ready using the boolean flag isWidgetReady
.
// app.component.ts
import { Component, OnInit } from '@angular/core'
import {
WidgetIsReadyService,
WidgetIsReadySubject,
} from '@livechat/widget-angular'
@Component({
/* ... */
templateUrl: './app.component.html',
})
export class AppComponent implements OnInit {
widgetIsReady$: WidgetIsReadySubject
constructor(widgetIsReadyService: WidgetIsReadyService) {
this.widgetIsReady$ = widgetIsReadyService.subject
}
ngOnInit() {
this.widgetIsReady$.subscribe((widgetIsReady) => {
console.log('AppComponent.ngOnInit.widgetIsReady', widgetIsReady)
})
}
}
<!-- app.component.html -->
<div>{{ widgetIsReady$ | async }}</div>
Access the chatId
and threadId
of the chat if there's one currently available.
// app.component.ts
import { Component, OnInit } from '@angular/core'
import {
WidgetChatDataService,
WidgetChatDataSubject,
} from '@livechat/widget-angular'
@Component({
/* ... */
templateUrl: './app.component.html',
})
export class AppComponent implements OnInit {
chatData$: WidgetChatDataSubject
constructor(chatDataService: WidgetChatDataService) {
this.chatData$ = chatDataService.subject
}
ngOnInit() {
this.chatData$.subscribe((chatData) => {
console.log('AppComponent.ngOnInit.chatData', chatData)
})
}
}
<!-- app.component.html -->
<div *ngIf="chatData$ | async as chatData">
<div>{{ chatData.availability }}</div>
<div>{{ chatData.visibility }}</div>
</div>
Access the current greeting id
and uniqueId
if one is currently displayed (received and not hidden).
// app.component.ts
import { Component, OnInit } from '@angular/core'
import {
WidgetGreetingService,
WidgetGreetingSubject,
} from '@livechat/widget-angular'
@Component({
/* ... */
templateUrl: './app.component.html',
})
export class AppComponent implements OnInit {
greeting$: WidgetGreetingSubject
constructor(greetingService: WidgetGreetingService) {
this.greeting$ = greetingService.subject
}
ngOnInit() {
this.greeting$.subscribe((greeting) => {
console.log('AppComponent.ngOnInit.greeting', greeting)
})
}
}
<!-- app.component.html -->
<div *ngIf="greeting$ | async as greeting">
<div>{{ greeting.availability }}</div>
<div>{{ greeting.visibility }}</div>
</div>
Access the id
, isReturning
, status
, and sessionVariables
of the current customer if the chat widget is loaded.
// app.component.ts
import { Component, OnInit } from '@angular/core'
import {
WidgetCustomerDataService,
WidgetCustomerDataSubject,
} from '@livechat/widget-angular'
@Component({
/* ... */
templateUrl: './app.component.html',
})
export class AppComponent implements OnInit {
customerData$: WidgetCustomerDataSubject
constructor(customerDataService: WidgetCustomerDataService) {
this.customerData$ = customerDataService.subject
}
ngOnInit() {
this.customerData$.subscribe((customerData) => {
console.log('AppComponent.ngOnInit.customerData', customerData)
})
}
}
<!-- app.component.html -->
<div *ngIf="customerData$ | async as customerData">
<div>{{ customerData.id }}</div>
<div>{{ customerData.isReturning }}</div>
<div>{{ customerData.status }}</div>
<ul>
<li *ngFor="let variable of customerData.sessionVariables | keyvalue">
{{ variable.value }}
</li>
</ul>
</div>
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.
// app.component.ts
import { Component } from '@angular/core'
import { EventHandlerPayload } from '@livechat/widget-angular'
@Component({
/* ... */
templateUrl: './app.component.html',
})
export class AppComponent {
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,
}
}
}
