# LiveKit Server API for Ruby Use this SDK to manage LiveKit rooms and create access tokens from your Ruby backend. This library is designed to work with Ruby 2.6.0 and above. ## Installation Add this line to your application's Gemfile: ### Gemfile ```ruby gem 'livekit-server-sdk' ``` and then `bundle install`. ### Install system-wide ```shell gem install livekit-server-sdk ``` ## Usage ### Creating Access Tokens Creating a token for participant to join a room. ```ruby require 'livekit' token = LiveKit::AccessToken.new(api_key: 'yourkey', api_secret: 'yoursecret') token.identity = 'participant-identity' token.name = 'participant-name' token.add_grant(roomJoin: true, room: 'room-name') puts token.to_jwt ``` By default, a token expires after 6 hours. You may override this by passing in `ttl` when creating the token. `ttl` is expressed in seconds. ### Setting Permissions with Access Tokens It's possible to customize the permissions of each participant. See more details at [access tokens guide](https://docs.livekit.io/guides/access-tokens#room-permissions). ### Room Service `RoomServiceClient` is a Twirp-based client that provides management APIs to LiveKit. You can connect it to your LiveKit endpoint. See [service apis](https://docs.livekit.io/guides/server-api) for a list of available APIs. ```ruby require 'livekit' client = LiveKit::RoomServiceClient.new('https://my.livekit.instance', api_key: 'yourkey', api_secret: 'yoursecret') name = 'myroom' client.list_rooms client.list_participants(room: name) client.mute_published_track(room: name, identity: 'participant', track_sid: 'track-id', muted: true) client.remove_participant(room: name, identity: 'participant') client.delete_room(room: name) ``` ### Egress Service `EgressServiceClient` is a ruby client to EgressService. Refer to [docs](https://docs.livekit.io/guides/egress) for more usage examples ```ruby require 'livekit' # starting a room composite to S3 const egressClient = LiveKit::EgressServiceClient.new( "https://your-url", api_key: 'key', api_secret: 'secret' ); info = egressClient.start_room_composite_egress( 'room-name', LiveKit::Proto::EncodedFileOutput.new( file_type: LiveKit::Proto::EncodedFileType::MP4, filepath: "my-recording.mp4", s3: LiveKit::Proto::S3Upload.new( access_key: 'access-key', secret: 'secret', region: 'bucket-region', bucket: 'bucket' ) ) ) puts info # starting a track composite to RTMP urls = Google::Protobuf::RepeatedField.new(:string, ['rtmp://url1', 'rtmps://url2']) info = egressClient.start_track_composite_egress( 'room-name', LiveKit::Proto::StreamOutput.new( protocol: LiveKit::Proto::StreamProtocol::RTMP, urls: urls ), audio_track_id: 'TR_XXXXXXXXXXXX', video_track_id: 'TR_XXXXXXXXXXXX' ) puts info ``` ### Environment Variables You may store credentials in environment variables. If api-key or api-secret is not passed in when creating a `RoomServiceClient` or `AccessToken`, the values in the following env vars will be used: - `LIVEKIT_API_KEY` - `LIVEKIT_API_SECRET` ## License The gem is available as open source under the terms of Apache 2.0 License.
