Accessing your application client from other devices in your local network
One advantage of running OpenVidu locally is that you can test your application client with other devices in your local network very easily without worrying about SSL certificates.
Access your application client through https://xxx-yyy-zzz-www.openvidu-local.dev:5443
, where xxx-yyy-zzz-www
part of the domain is your LAN private IP address with dashes (-) instead of dots (.). For more information, see section Accessing your app from other devices in your network.
Understanding the code#
This tutorial is an Angular project generated with Angular CLI tool. Therefore, you will see many configuration files and other components that are not the primary focus of this tutorial. We will concentrate on the following files in the src
directory:
main.ts
: This file defines the root application component. It imports theOpenViduComponentsModule
, where we configure the OpenVidu Components Angular library.app/app.component.ts
: This file defines the AppComponent, the primary and sole component of the application. It is responsible for requesting the OpenVidu token and passing it to the videoconference component, facilitating the connection to the OpenVidu Room.styles.scss
: This file defines the global styles of the application. Here, you can customize the UI of the OpenVidu Components Angular library.
To use OpenVidu Components Angular in your application, you need to install the library and import the OpenViduComponentsModule
in your Angular module. Let's see how to do this:
-
Create an Angular Project (version 17 or higher)
To begin, you will need to create a new Angular project if you haven't already. Ensure you have Node.js and the Angular CLI installed. Then, run the following command to create a new Angular project:
Replace
your-project-name
with the desired name for your project. -
Add Angular Material to your project
OpenVidu Components Angular needs Angular Material, which provides a range of UI components. To add Angular Material to your project, navigate to your project directory and run:
-
Install OpenVidu Components Angular
With your Angular project set up, it's time to add videoconferencing capabilities with OpenVidu Components Angular. Install the library using npm:
-
Import and use OpenVidu Components Angular
To use OpenVidu Components Angular in your application, you need to:
- Import the
OpenViduComponentsModule
in your Angular application. - Configure the module with the
OpenViduComponentsConfig
object. - Add the component to your template file.
- Assign the OpenVidu token and LiveKit URL to the component.
- Customize the appearance of the components using CSS variables.
- Import the
In your main.ts
application file, import the it and configure it as follows:
// Other imports ...
import { OpenViduComponentsModule, OpenViduComponentsConfig } from 'openvidu-components-angular';
const config: OpenViduComponentsConfig = {
production: true,
};
bootstrapApplication(AppComponent, {
providers: [
importProvidersFrom(
OpenViduComponentsModule.forRoot(config)
// Other imports ...
),
provideAnimations(),
],
}).catch((err) => console.error(err));
Use the ov-videoconference
component to create a videoconference. This component requires a token to connect to the OpenVidu Room. The AppComponent
class is responsible for requesting the token and passing it to the ov-videoconference
component.
import { OpenViduComponentsModule } from 'openvidu-components-angular';
@Component({
selector: 'app-root',
template:`
<ov-videoconference
[token]="token"
[livekitUrl]="LIVEKIT_URL"
(onTokenRequested)="onTokenRequested($event)"
>
</ov-videoconference>
`,
styles: [''],
standalone: true,
imports: [OpenViduComponentsModule],
})
export class AppComponent {
// For local development, leave these variables empty
// For production, configure them with correct URLs depending on your deployment
APPLICATION_SERVER_URL = ''; // (1)!
LIVEKIT_URL = ''; // (2)!
// The name of the room to join.
roomName = 'openvidu-custom-ui'; // (3)!
// The token used to join the room.
token!: string; // (4)!
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/';
}
}
}
// Requests a token to join the room with the given participant name.
async onTokenRequested(participantName: string) { // (5)!
const { token } = await this.getToken(this.roomName, participantName);
this.token = token;
}
// Retrieves a token to join the room with the given name and participant name.
getToken(roomName: string, participantName: string): Promise<any> { // (6)!
// Requesting token to the server application
}
}
APPLICATION_SERVER_URL
: URL to communicate the client application with the server application to request OpenVidu tokens.LIVEKIT_URL
: URL to communicate the client application with the LiveKit server.roomName
: OpenVidu Room identifier. This is the room where the VideoconferenceComponent will connecttoken
: OpenVidu Token used to connect to the OpenVidu Room.onTokenRequested
method that fires when the VideoconferenceComponent requests a token to connect to the OpenVidu Room.getToken
method that requests a token to the server application.
The app.component.ts
file declares the following properties and methods:
APPLICATION_SERVER_URL
: URL to communicate the client application with the server application to request OpenVidu tokens.LIVEKIT_URL
: URL to communicate the client application with the LiveKit server.roomName
: OpenVidu Room identifier. This is the room where the VideoconferenceComponent will connecttoken
: OpenVidu Token used to connect to the OpenVidu Room.onTokenRequested
method that fires when the VideoconferenceComponent requests a token to connect to the OpenVidu Room.getToken
method that requests a token to the server application.
Configure the URLs
For local development, leave APPLICATION_SERVER_URL
and LIVEKIT_URL
variables empty. The function configureUrls()
will automatically configure them with default values. However, for production, you should configure these variables with the correct URLs depending on your deployment.
The OpenVidu Components Angular library provides a set of CSS variables that you can use to customize the appearance of the components. You can define these variables in your application's global styles file (e.g. styles.scss
).
:root {
--ov-primary-color: #303030; /* Primary interface color */
--ov-secondary-color: #3e3f3f; /* Secondary interface color */
--ov-tertiary-color: #598eff; /* Tertiary accent color for elements */
--ov-warn-color: #eb5144; /* Warning color for alerts and notifications */
--ov-light-color: #e6e6e6; /* Light color for elements */
--ov-accent-color: #ffae35; /* Accent color for standout UI elements */
--ov-logo-background-color: #3a3d3d; /* Background color for the logo area */
--ov-text-color: #ffffff; /* Default text color */
--ov-panel-text-color: #1d1d1d; /* Text color for panel elements */
--ov-panel-background: #ffffff; /* Background color for panels */
--ov-buttons-radius: 50%; /* Border-radius for circular buttons */
--ov-leave-button-radius: 10px; /* Border-radius for the leave button */
--ov-video-radius: 5px; /* Border-radius for video elements */
--ov-panel-radius: 5px; /* Border-radius for panel elements */
}
Customizing the UI#
To customize the appearance of OpenVidu Components, simply redefine the necessary CSS variables in your styles.scss
file. For instance, to change the primary color used throughout your application, you would update the --ov-primary-color
variable as shown below:
:root {
--ov-primary-color: #yourNewColor; /* Replace #yourNewColor with your chosen hex color code */
/* Others variables ... */
}
The library also allows you to customize shape of buttons, panels and videos customization, the background color personalization of panels, buttons and videoconference and also you can change the text color.
Replacing the branding logo#
You can replace the branding logo with your own. Just modify the src/assets/images/logo.png
file with your own logo.
