Services

The LiveChatWidgetModule, exported from this package, registers a set of injectable services. All of them expose a subscribable BehaviorSubject instance. It allows for consuming reactive data from the chat widget in any place of the application, as long as the LiveChatWidget component is rendered in the tree.

WidgetStateService

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>
WidgetIsReadyService

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>
WidgetChatDataService

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>
WidgetGreetingService

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>
WidgetCustomerDataService

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>
