Description

The *ovToolbarAdditionalPanelButtons directive allows to add additional panel buttons to the toolbar. In the example below we've added a simple button without any functionality. To learn how to toggle the panel check the AdditionalPanelsDirective.

Example :
import { HttpClient } from '@angular/common/http';
import { Component } from '@angular/core';
import { lastValueFrom } from 'rxjs';

import { OpenViduComponentsModule } from 'openvidu-components-angular';
import { MatIconButton } from '@angular/material/button';
import { MatIcon } from '@angular/material/icon';

@Component({
    selector: 'app-root',
    template: `
        <ov-videoconference
            [token]="token"
            [livekitUrl]="LIVEKIT_URL"
            [toolbarDisplayRoomName]="false"
            (onTokenRequested)="onTokenRequested($event)"
        >
            <div *ovToolbarAdditionalPanelButtons style="text-align: center;">
                <button mat-icon-button (click)="onButtonClicked()">
                    <mat-icon>star</mat-icon>
                </button>
            </div>
        </ov-videoconference>
    `,
    styles: [],
    standalone: true,
    imports: [OpenViduComponentsModule, MatIconButton, MatIcon],
})
export class AppComponent {
    // For local development, leave these variables empty
    // For production, configure them with correct URLs depending on your deployment

    APPLICATION_SERVER_URL = '';
    LIVEKIT_URL = '';

    // Set the room name
    roomName = 'toolbar-additional-panel-btn';

    // Initialize the token variable
    token!: string;

    constructor(private httpClient: HttpClient) {
        this.configureUrls();
    }

    private configureUrls() {
        // If APPLICATION_SERVER_URL is not configured, use default value from local development
        if (!this.APPLICATION_SERVER_URL) {
            if (window.location.hostname === 'localhost') {
                this.APPLICATION_SERVER_URL = 'http://localhost:6080/';
            } else {
                this.APPLICATION_SERVER_URL =
                    'https://' + window.location.hostname + ':6443/';
            }
        }

        // If LIVEKIT_URL is not configured, use default value from local development
        if (!this.LIVEKIT_URL) {
            if (window.location.hostname === 'localhost') {
                this.LIVEKIT_URL = 'ws://localhost:7880/';
            } else {
                this.LIVEKIT_URL = 'wss://' + window.location.hostname + ':7443/';
            }
        }
    }

    // Method to request a token for a participant
    async onTokenRequested(participantName: string) {
        const { token } = await this.getToken(this.roomName, participantName);
        this.token = token;
    }

    // Method to handle button click
    onButtonClicked() {
        alert('button clicked');
    }

    // Method to get a token from the backend
    getToken(roomName: string, participantName: string): Promise<any> {
        try {
            return lastValueFrom(
                this.httpClient.post<any>(this.APPLICATION_SERVER_URL + 'token', {
                    roomName,
                    participantName,
                })
            );
        } catch (error: any) {
            if (error.status === 404) {
                throw {
                    status: error.status,
                    message: 'Cannot connect with backend. ' + error.url + ' not found',
                };
            }
            throw error;
        }
    }
}
