OpenVidu Meet WebComponent Commands & Events Tutorial#
This tutorial extends the basic WebComponent tutorial to add advanced WebComponent functionality through commands and event handling. It demonstrates how to interact with the OpenVidu Meet WebComponent programmatically and respond to meeting events.
The application includes all the features from the basic WebComponent tutorial, plus:
- WebComponent commands: Control the meeting programmatically (e.g., end meeting for moderators).
- Event handling: Listen to and respond to WebComponent events (joined, left, closed).
- Role-based UI: Display different interface elements based on user role (moderator/speaker).
- Meeting header: Show room information and controls above the WebComponent.
- Enhanced room management: In-memory room tracking with unique names per room.

Understanding the code#
This tutorial builds upon the basic WebComponent tutorial, adding advanced WebComponent interaction capabilities and enhanced room management. We'll focus on the key differences and new functionality.
Backend#
The backend is identical to previous tutorials. It provides the same three REST API endpoints:
POST /rooms
: Create a new room with the given room name.GET /rooms
: Get the list of rooms.DELETE /rooms/:roomId
: Delete a room with the given room ID.
For detailed backend documentation, please refer to the Direct Link tutorial backend section.
Frontend modifications#
The frontend changes focus on enhanced room management, WebComponent event handling, and role-based UI features.
Enhanced room template#
The room template now passes additional parameters including role information:
app.js | |
---|---|
|
The template now provides the room name and user role to the joinRoom()
function, enabling role-based functionality and proper room identification.
Advanced room joining with commands and events#
The joinRoom()
function has been significantly enhanced to handle WebComponent events and commands:
app.js | |
---|---|
|
- Hide the home screen.
- Show the room screen.
- Hide the room header until the local participant joins.
- Inject the OpenVidu Meet WebComponent into the meeting container with the specified room URL.
- Add an event listener for the
joined
event, which is triggered when the local participant joins the room. - Set the room name in the header.
- Show the end meeting button if the user is a moderator.
- Call the
endMeeting()
method of the OpenVidu Meet WebComponent to end the meeting when the moderator clicks theEnd Meeting
button. - Add an event listener for the
left
event, which is triggered when the local participant leaves the room. - Add an event listener for the
closed
event, which is triggered when the OpenVidu Meet component is closed.
The enhanced joinRoom()
function now performs the following actions:
- Hides the home screen and shows the room screen.
- Hides the room header until the local participant joins.
- Injects the OpenVidu Meet WebComponent into the meeting container with the specified room URL.
-
Configures event listeners for the OpenVidu Meet WebComponent to handle different events:
joined
: This event is triggered when the local participant joins the room. It shows the room header with the room name and displays theEnd Meeting
button if the user is a moderator. It also adds an event listener for theEnd Meeting
button to call theendMeeting()
method of the OpenVidu Meet WebComponent to end the meeting. This method disconnects all participants and ends the meeting for everyone.left
: This event is triggered when the local participant leaves the room. It hides the room header.closed
: This event is triggered when the OpenVidu Meet component is closed. It hides the room screen and shows the home screen.
