tools-only RealtimeKit API Reference
Complete API reference for Meeting object, REST endpoints, and SDK methods.
Meeting Object API
meeting.self - Local Participant
// Properties: id, userId, name, audioEnabled, videoEnabled, screenShareEnabled, audioTrack, videoTrack, screenShareTracks, roomJoined, roomState
// Methods
await meeting.self.enableAudio() / disableAudio() / enableVideo() / disableVideo() / enableScreenShare() / disableScreenShare()
await meeting.self.setName("Name") // Before join only
await meeting.self.setDevice(device)
const devices = await meeting.self.getAllDevices() / getAudioDevices() / getVideoDevices() / getSpeakerDevices()
// Events: 'roomJoined', 'audioUpdate', 'videoUpdate', 'screenShareUpdate', 'deviceUpdate', 'deviceListUpdate'
meeting.self.on('roomJoined', () => {})
meeting.self.on('audioUpdate', ({ audioEnabled, audioTrack }) => {})
meeting.participants - Remote Participants
Collections:
meeting.participants.joined / active / waitlisted / pinned // Maps
const participants = meeting.participants.joined.toArray()
const count = meeting.participants.joined.size()
const p = meeting.participants.joined.get('peer-id')
Participant Properties:
participant.id / userId / name
participant.audioEnabled / videoEnabled / screenShareEnabled
participant.audioTrack / videoTrack / screenShareTracks
Events:
meeting.participants.joined.on('participantJoined', (participant) => {})
meeting.participants.joined.on('participantLeft', (participant) => {})
meeting.meta - Metadata
meeting.meta.meetingId / meetingTitle / meetingStartedTimestamp
meeting.chat - Chat
meeting.chat.messages // Array
await meeting.chat.sendTextMessage("Hello") / sendImageMessage(file)
meeting.chat.on('chatUpdate', ({ message, messages }) => {})
meeting.polls - Polling
meeting.polls.items // Array
await meeting.polls.create(question, options, anonymous, hideVotes)
await meeting.polls.vote(pollId, optionIndex)
meeting.plugins - Collaborative Apps
meeting.plugins.all // Array
await meeting.plugins.activate(pluginId) / deactivate()
meeting.ai - AI Features
meeting.ai.transcripts // Live transcriptions (when enabled in Preset)
Core Methods
await meeting.join() // Emits 'roomJoined' on meeting.self
await meeting.leave()
TypeScript Types
import type { RealtimeKitClient, States, UIConfig, Participant } from '@cloudflare/realtimekit';
// Main interface
interface RealtimeKitClient {
self: SelfState; // Local participant (id, userId, name, audioEnabled, videoEnabled, roomJoined, roomState)
participants: { joined, active, waitlisted, pinned }; // Reactive Maps
chat: ChatNamespace; // messages[], sendTextMessage(), sendImageMessage()
polls: PollsNamespace; // items[], create(), vote()
plugins: PluginsNamespace; // all[], activate(), deactivate()
ai: AINamespace; // transcripts[]
meta: MetaState; // meetingId, meetingTitle, meetingStartedTimestamp
join(): Promise<void>;
leave(): Promise<void>;
}
// Participant (self & remote share same shape)
interface Participant {
id: string; // Peer ID (changes on rejoin)
userId: string; // Persistent participant ID
name: string;
audioEnabled: boolean;
videoEnabled: boolean;
screenShareEnabled: boolean;
audioTrack: MediaStreamTrack | null;
videoTrack: MediaStreamTrack | null;
screenShareTracks: MediaStreamTrack[];
}
Store Architecture
RealtimeKit uses reactive store (event-driven updates, live Maps):
// Subscribe to state changes
meeting.self.on('audioUpdate', ({ audioEnabled, audioTrack }) => {});
meeting.participants.joined.on('participantJoined', (p) => {});
// Access current state synchronously
const isAudioOn = meeting.self.audioEnabled;
const count = meeting.participants.joined.size();
Key principles: State updates emit events after changes. Use .toArray() sparingly. Collections are live Maps.

Initialization → Join Intent → [Waitlist?] → Meeting Screen (Stage) → Ended
↓ Approved
[Rejected → Ended]
UI Kit handles state transitions automatically.
