Incoming Call - CometChat Docs

Overview

The Incoming call is a Component that serves as a visual representation when the user receives an incoming call, such as a voice call or video call, providing options to answer or decline the call.

The Incoming Call is comprised of the following base components:

Components	Description
cometchat-list-item	This component’s view consists of avatar, status indicator , title, and subtitle. The fields are then mapped with the SDK’s user, group class.
cometchat-icon	This component displays an icon. It currently supports only svg icons
cometchat-label	This component provides descriptive information about the associated UI element.
cometchat-button	This component represents a button with optional icon and text.
cometchat-avatar	This component component displays an image or user’s avatar with fallback to the first two letters of the username

Usage

Integration

import { CUSTOM_ELEMENTS_SCHEMA, NgModule } from "@angular/core";
import { BrowserModule } from "@angular/platform-browser";
import { CometChatIncomingCall } from "@cometchat/chat-uikit-angular";
import { AppComponent } from "./app.component";

@NgModule({
  imports: [BrowserModule, CometChatIncomingCall],
  declarations: [AppComponent],
  providers: [],
  bootstrap: [AppComponent],
  schemas: [CUSTOM_ELEMENTS_SCHEMA],
})
export class AppModule {}

Actions

Actions dictate how a component functions. They are divided into two types: Predefined and User-defined. You can override either type, allowing you to tailor the behavior of the component to fit your specific needs.

1. onAccept

onAccept is triggered when you click the accept button of the Incoming Call component. You can override this action using the following code snippet.

import { CometChat } from '@cometchat/chat-sdk-javascript';
import { Component, OnInit } from '@angular/core';
import {  CometChatThemeService, CometChatUIKit } from '@cometchat/chat-uikit-angular';
import "@cometchat/uikit-elements";

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {

  constructor(private themeService:CometChatThemeService) {
    themeService.theme.palette.setMode("light")
    themeService.theme.palette.setPrimary({ light: "#6851D6", dark: "#6851D6" })
  }
  public handleOnAccept = (call: CometChat.Call) => {
    console.log("your custom on accept actions", call);
  };
  onLogin(UID?: any) {
    CometChatUIKit.login({ uid: UID }).then(
      (user) => {
        setTimeout(() => {
          window.location.reload();
        }, 1000);
      },
      (error) => {
        console.log("Login failed with exception:", { error });
      }
    );
  }
}

2. onDecline

onDecline is triggered when you click the Decline button of the Incoming Call component. You can override this action using the following code snippet.

import { CometChat } from '@cometchat/chat-sdk-javascript';
import { Component, OnInit } from '@angular/core';
import {  CometChatThemeService, CometChatUIKit } from '@cometchat/chat-uikit-angular';
import "@cometchat/uikit-elements";

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {

  constructor(private themeService:CometChatThemeService) {
    themeService.theme.palette.setMode("light")
    themeService.theme.palette.setPrimary({ light: "#6851D6", dark: "#6851D6" })
  }
  public handleOnDecline = (call: CometChat.Call) => {
    console.log("your custom on decline action");
  };
  onLogin(UID?: any) {
    CometChatUIKit.login({ uid: UID }).then(
      (user) => {
        setTimeout(() => {
          window.location.reload();
        }, 1000);
      },
      (error) => {
        console.log("Login failed with exception:", { error });
      }
    );
  }
}

3. onError

This action doesn’t change the behavior of the component but rather listens for any errors that occur in the Incoming Call component.

import { CometChat } from '@cometchat/chat-sdk-javascript';
import { Component, OnInit } from '@angular/core';
import {  CometChatThemeService, CometChatUIKit } from '@cometchat/chat-uikit-angular';
import "@cometchat/uikit-elements";

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {

  constructor(private themeService:CometChatThemeService) {
    themeService.theme.palette.setMode("light")
    themeService.theme.palette.setPrimary({ light: "#6851D6", dark: "#6851D6" })
  }
  public handleOnError = (error: CometChat.CometChatException) => {
    console.log("your custom on error action", error);
  };
  onLogin(UID?: any) {
    CometChatUIKit.login({ uid: UID }).then(
      (user) => {
        setTimeout(() => {
          window.location.reload();
        }, 1000);
      },
      (error) => {
        console.log("Login failed with exception:", { error });
      }
    );
  }
}

Filters

Filters allow you to customize the data displayed in a list within a Component. You can filter the list based on your specific criteria, allowing for a more customized. Filters can be applied using RequestBuilders of Chat SDK. The Incoming Call component does not have any exposed filters.

Events

Events are emitted by a Component. By using event you can extend existing functionality. Being global events, they can be applied in Multiple Locations and are capable of being Added or Removed. The list of events emitted by the Incoming Call component is as follows.

Event	Description
ccCallRejected	This event is triggered when the initiated call is rejected by the receiver.
ccCallAccepted	This event is triggered when the initiated call is accepted by the receiver.
ccCallEnded	This event is triggered when the initiated call successfully ends.

Adding CometChatCallEvents Listener’s

import {CometChatCallEvents} from "@cometchat/chat-uikit-angular";

this.ccCallRejected = CometChatCallEvents.ccCallRejected.subscribe(
(call: CometChat.Call) => {
        // Your Code
  }
);

this.ccCallAccepted = CometChatCallEvents.ccCallAccepted.subscribe(
(call: CometChat.Call) => {
        // Your Code
  }
);

this.ccCallEnded = CometChatCallEvents.ccCallEnded.subscribe(
(call: CometChat.Call) => {
        // Your Code
  }
);

Removing CometChatCallEvents Listener’s

this.ccCallRejected.unsubscribe();
this.ccCallAccepted.unsubscribe();
this.ccCallEnded.unsubscribe();

Customization

To fit your app’s design requirements, you can customize the appearance of the Incoming Call component. We provide exposed methods that allow you to modify the experience and behavior according to your specific needs.

Style

Using Style you can customize the look and feel of the component in your app, These parameters typically control elements such as the color, size, shape, and fonts used within the component.

1. IncomingCall Style

To customize the appearance, you can assign a IncomingCallStyle object to the Incoming Call component.

Example In this example, we are employing the IncomingCallStyle.

import { CometChat } from '@cometchat/chat-sdk-javascript';
import { Component, OnInit } from '@angular/core';
import {  CometChatThemeService, CometChatUIKit } from '@cometchat/chat-uikit-angular';
import { IncomingCallStyle } from '@cometchat/uikit-shared';
import "@cometchat/uikit-elements";

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {

  constructor(private themeService:CometChatThemeService) {
    themeService.theme.palette.setMode("light")
    themeService.theme.palette.setPrimary({ light: "#6851D6", dark: "#6851D6" })
  }
  incomingCallStyle = new IncomingCallStyle({
    acceptButtonBackground: "#7b49de",
    acceptButtonTextColor: "#ffffff",
    background: "#8761d4",
    declineButtonBackground: "#4b08d1",
  });
  onLogin(UID?: any) {
    CometChatUIKit.login({ uid: UID }).then(
      (user) => {
        setTimeout(() => {
          window.location.reload();
        }, 1000);
      },
      (error) => {
        console.log("Login failed with exception:", { error });
      }
    );
  }
}

import { CometChat } from '@cometchat/chat-sdk-javascript';
import { Component, OnInit } from '@angular/core';
import {  CometChatThemeService, CometChatUIKit, AvatarStyle } from '@cometchat/chat-uikit-angular';
import "@cometchat/uikit-elements";

@Component({
  selector: 'app-root',

  });
  onLogin(UID?: any) {
    CometChatUIKit.login({ uid: UID }).then(
      (user) => {
        setTimeout(() => {
          window.location.reload();
        }, 1000);
      },
      (error) => {
        console.log("Login failed with exception:", { error });
      }
    );
  }
}

3. ListItem Style

If you want to apply customized styles to the List Item component within the Incoming Call Component, you can use the following code snippet. For more information, you can refer ListItem Styles.

  });
  onLogin(UID?: any) {
    CometChatUIKit.login({ uid: UID }).then(
      (user) => {
        setTimeout(() => {
          window.location.reload();
        }, 1000);
      },
      (error) => {
        console.log("Login failed with exception:", { error });
      }
    );
  }
}

Functionality

These are a set of small functional customizations that allow you to fine-tune the overall experience of the component. With these, you can change text, set custom icons, and toggle the visibility of UI elements. Here is a code snippet demonstrating how you can customize the functionality of the Incoming Call component.

import { CometChat } from '@cometchat/chat-sdk-javascript';
import { Component, OnInit } from '@angular/core';
import {  CometChatThemeService, CometChatUIKit } from '@cometchat/chat-uikit-angular';
import "@cometchat/uikit-elements";

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {

  constructor(private themeService:CometChatThemeService) {
    themeService.theme.palette.setMode("light")
    themeService.theme.palette.setPrimary({ light: "#6851D6", dark: "#6851D6" })
  }

  onLogin(UID?: any) {
    CometChatUIKit.login({ uid: UID }).then(
      (user) => {
        setTimeout(() => {
          window.location.reload();
        }, 1000);
      },
      (error) => {
        console.log("Login failed with exception:", { error });
      }
    );
  }
}

Default:

Custom:

Below is a list of customizations along with corresponding code snippets

Property	Description	Code
acceptButtonText	Used to set custom accept button text	`[acceptButtonText]="'Your Custom Accept Button Text'"`
declineButtonText	Used to set custom decline button text	`[declineButtonText]="'Your Decline Button Text'"`
customSoundForCalls	Used to set custom sound for incoming calls	`[customSoundForCalls]="customSoundForCalls"`
disableSoundForCalls	Used to disable/enable the sound of incoming calls, by default it is set to false	`[disableSoundForCalls]="true"`
call	CometChat call object consumed by the component to launch itself	`[call]="callObject"`

Advanced

For advanced-level customization, you can set custom views to the component. This lets you tailor each aspect of the component to fit your exact needs and application aesthetics. You can create and define your views, layouts, and UI elements and then incorporate those into the component.

SubtitleView

By using the subtitleView property, you can modify the SubtitleView to meet your specific needs. Example Default:

Custom:

import { CometChat } from '@cometchat/chat-sdk-javascript';
import { Component, OnInit } from '@angular/core';
import {  CometChatThemeService, CometChatUIKit } from '@cometchat/chat-uikit-angular';
import "@cometchat/uikit-elements";

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {

  constructor(private themeService:CometChatThemeService) {
    themeService.theme.palette.setMode("light")
    themeService.theme.palette.setPrimary({ light: "#6851D6", dark: "#6851D6" })
  }

  onLogin(UID?: any) {
    CometChatUIKit.login({ uid: UID }).then(
      (user) => {
        setTimeout(() => {
          window.location.reload();
        }, 1000);
      },
      (error) => {
        console.log("Login failed with exception:", { error });
      }
    );
  }
}

Configuration

Configurations offer the ability to customize the properties of each individual component within a Composite Component. The Incoming Call Component is a Composite Component and it has a specific set of configuration for each of its components.

OngoingCall

If you want to customize the properties of the OngoingCall Component inside Incoming Call Component, you need use the CallScreenConfiguration object. The OngoingCallConfiguration provides access to all the Action, Filters, Styles, Functionality, and Advanced properties of the OngoingCall component.

Please note that the Properties marked with the 🛑 symbol are not accessible within the Configuration Object.

Example

In this example, we will show how you can display the call recording button in the OngoingCall component using ongoingCallConfiguration.

import { CometChat } from '@cometchat/chat-sdk-javascript';
import { Component, OnInit } from '@angular/core';
import {  CometChatThemeService, CometChatUIKit, CallScreenConfiguration, CometChatUIKitCalls, CometChatUIKitConstants } from '@cometchat/chat-uikit-angular';
import "@cometchat/uikit-elements";

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {

  constructor(private themeService:CometChatThemeService) {
    themeService.theme.palette.setMode("light")
    themeService.theme.palette.setPrimary({ light: "#6851D6", dark: "#6851D6" })
  }
  public ongoingCallConfiguration!: CallScreenConfiguration;
  ngOnInit(): void {
    this.ongoingCallConfiguration = new CallScreenConfiguration({
      callSettingsBuilder: this.customSettingBuilderForIncoming
    });
  }
  customSettingBuilderForIncoming(call: any) {
    const builder = new CometChatUIKitCalls.CallSettingsBuilder();
    if (call?.getType() == CometChatUIKitConstants.MessageTypes.audio) {
      builder
        .enableDefaultLayout(true)
        .setIsAudioOnlyCall(true)
        .showRecordingButton(true);
    }
    else if (call?.getType() == CometChatUIKitConstants.MessageTypes.video) {
      builder
        .enableDefaultLayout(true)
        .setIsAudioOnlyCall(false)
        .showRecordingButton(true);
    }
    return builder;
  }

  onLogin(UID?: any) {
    CometChatUIKit.login({ uid: UID }).then(
      (user) => {
        setTimeout(() => {
          window.location.reload();
        }, 1000);
      },
      (error) => {
        console.log("Login failed with exception:", { error });
      }
    );
  }
}
