I'd be happy to guide you through adding video grants in JavaScript for LiveKit. Here’s a step-by-step approach to help you get started: 1. Import Required Modules: First, import

AccessToken

and

VideoGrant

from the

livekit-server-sdk

package.

import { AccessToken, VideoGrant } from 'livekit-server-sdk';

2. Initialize the Access Token: Next, create an

AccessToken

using your LiveKit API key and secret.

const at = new AccessToken('api-key', 'secret-key', { identity: 'participant-identity' });

3. Define the Video Grant: Here, you specify the permissions and room details in a

VideoGrant

object.

const videoGrant = { room: 'my-room', roomJoin: true, canPublish: true, canSubscribe: true };

4. Add the Video Grant: Then, attach the

VideoGrant

to your access token using the

addGrant()

method.

at.addGrant(videoGrant);

5. Generate the JWT Token: Finally, generate the signed JWT token by calling

toJwt()

.

const token = await at.toJwt(); console.log('access token', token);

To bring it all together, here’s a complete example for you to try out:

import { AccessToken, VideoGrant } from 'livekit-server-sdk';

const roomName = 'name-of-room';
const participantName = 'user-name';

const at = new AccessToken('api-key', 'secret-key', { identity: participantName });

const videoGrant = { room: roomName, roomJoin: true, canPublish: true, canPublishData: true, canSubscribe: true };

at.addGrant(videoGrant);

const token = await at.toJwt();
console.log('access token', token);
