### About

`opv-gotomeeting` is an GoToMeeting-styled component with a predefined layout, which you can use out-of-the-box.
In addition, you have multiple methods and events you can use to personalized the user experience.

These are the events AngularOpenVidu exposes for the user of the module.

| `onCustomNotification`     | `(customObject)` | triggers when a custom notification from a participant is received |

### i18n - Localizing labels and messages

*By default the labels and messages are in English*

The various text strings used by the component are provided through `OpenViduGoToMeetingIntl`.
Localization of these messages can be done by providing a subclass with translated values in your application root module.

Here is an example for an Spanish locale:

```js
import { Injectable } from '@angular/core';
import { OpenViduGoToMeetingIntl } from 'angular-openvidu';

@Injectable()
export class MySpanishOpenViduGoToMeetingIntl extends OpenViduGoToMeetingIntl {
	loadingLabel = 'Cargando...';
	connectingLabel = 'Connectando...';
	connectingToRoomLabel = 'Entrando en la sala...';
	youLeftTheRoomLabel = 'Has salido de la sala';
	...
}
```

And then add it to your `NgModule`, like this:

```js
import { OpenViduModule, OpenViduGoToMeetingIntl } from 'angular-openvidu';

@NgModule({
	imports: [ OpenViduModule ],
	providers: [
		{provide: OpenViduGoToMeetingIntl, useClass: MySpanishOpenViduGoToMeetingIntl},
	]
})
export class AppModule {

}
```

And you are good to go.
