What is Scheduler module

The Scheduler module is part of the Proview SDK, exposed as Proview.scheduler. It provides a candidate-facing interface for managing interview scheduler workflows with integrated authentication. Once initialized, it lets your application:
  • Fetch meetings — retrieve a candidate’s scheduled interviews and their current state.
  • Respond to interviews — accept, decline, propose a new time, or submit availability on behalf of the candidate.
  • Render scheduler UI — mount a prebuilt scheduler interface in inline, sidebar, or modal layout.
  • React to state changes — subscribe to events for phase transitions, route changes, and errors.
Both Promise-based and callback-based async patterns are supported. All UI text is localizable via the locale option.

​
Quickstart

All async methods support both Promises and an optional callback. This walkthrough uses Promises. See Callback Signature for the callback form.

​
1. Initialize credential

The SDK supports Firebase as a credentialing provider for authentication. 
const firebaseCredential = Proview.auth.FirebaseAuthStrategy({
  token: 'your-firebase-auth-token',
});

​
2. Initialize scheduler

Call Proview.scheduler.init() with the Firebase credential. The SDK authenticates the user and makes the user object available globally at Proview.user. 
const scheduler = Proview.scheduler.init({
  dsn: 'project-dsn',
  projectId: 'project-123',
  credential: firebaseCredential,
});

// Access user object globally
const user = Proview.user;
console.log(user.uid, user.email, user.displayName);

// Get ID token when needed
const idToken = await user.getIdToken();

​
3. Fetch meetings

const meetings = await scheduler.fetchMeetings();
// => MeetingSummary[]

​
4. Fetch state for a specific meeting

const state = await scheduler.fetchMeeting('meeting_123');
// => SchedulerState | null

​
5. Respond to an interview

Accept: 
const updated = await scheduler.acceptMeeting({
  meetingId: 'meeting_123',
  interviewId: 'interview_456',
  reason: 'Confirmed',
});
Decline: 
const updated = await scheduler.declineMeeting({
  meetingId: 'meeting_123',
  interviewId: 'interview_456',
  reason: 'Not available',
});
Propose a new time (when the candidate wants to reschedule): 
const updated = await scheduler.proposeNewTime({
  meetingId: 'meeting_123',
  interviewId: 'interview_456',
  slotId: 'slot_789',
  note: 'Prefer morning slots',
});
Set availability (saves the candidate’s general availability; not scoped to a single meeting): 
const updated = await scheduler.setAvailability({
  meetingId: 'meeting_123',
  weekly: {
    monday: [{ start: '09:00', end: '17:00' }],
    wednesday: [{ start: '10:00', end: '15:00' }],
  },
  blockedDates: ['2026-04-01'],
});

​
6. Render the scheduler UI

Mount the scheduler UI into any container element. Three layout modes are supported: inline, sidebar, and modal. 
const mounted = scheduler.mount({
  initialView: 'scheduled_interviews',
  mountMode: {
    mode: 'inline',
    containerId: 'proview-scheduler-root',
  },
});

​
7. Navigate programmatically

Use scheduler.navigate() to trigger a view change from outside the UI: 
scheduler.navigate('interviews', { meetingId: 'meeting_123' });
Use mounted.setView() to change the view from the mounted instance directly: 
mounted.setView('scheduled_interviews', { meetingId: 'meeting_123' });

​
8. Listen to events

on() returns an unsubscribe function, useful for cleanup in component lifecycles: 
const unsubscribe = scheduler.on('state.changed', ({ previous, current }) => {
  console.log('Phase changed:', previous.phase, '->', current.phase);
});

// Later, to stop listening:
unsubscribe();

​
9. Teardown

When done, unmount the UI and destroy the session: 
mounted.unmount();
scheduler.destroy();

​
API Reference

​
Proview.scheduler.init(input)

Creates a scheduler session. Input 
type SchedulerInitInput = {
  dsn: string;               // Required: Project DSN
  projectId: string;         // Required: Project ID
  credential: Credential;    // Required: Authentication credential (e.g., FirebaseAuthStrategy)
};
Returns — SchedulerSession 
type SchedulerSession = {
  fetchMeeting(meetingId: string, cb?: MeetingStateCallback): Promise<SchedulerState | null>;
  fetchMeetings(cb?: MeetingsCallback): Promise<MeetingSummary[]>;
  acceptMeeting(payload: AcceptMeetingInput, cb?: MeetingStateCallback): Promise<SchedulerState>;
  declineMeeting(payload: DeclineMeetingInput, cb?: MeetingStateCallback): Promise<SchedulerState>;
  proposeNewTime(payload: ProposeNewTimeInput, cb?: MeetingStateCallback): Promise<SchedulerState>;
  setAvailability(payload: SetAvailabilityInput, cb?: MeetingStateCallback): Promise<SchedulerState>;
  mount(options: MountOptions): MountedSchedulerUi;
  navigate(view: SchedulerView, options: { meetingId: string }): void;
  getCurrentView(): SchedulerView;
  on<E extends SchedulerEventName>(event: E, handler: (payload: SchedulerEventPayloadMap[E]) => void): () => void;
  off<E extends SchedulerEventName>(event: E, handler: (payload: SchedulerEventPayloadMap[E]) => void): void;
  destroy(): void;
};
The authenticated user is available globally at Proview.user after initialization.

​
User Object

After initializing the scheduler module, Proview.user provides a Firebase-compatible user object accessible globally. User Interface 
type User = {
  uid: string;                      // User's unique ID
  email: string | null;             // User's email address
  displayName: string | null;       // User's display name
  emailVerified: boolean;           // Email verification status
  isAnonymous?: boolean;            // Is anonymous user
  metadata?: UserMetadata;          // Creation and last sign-in time
  providerData?: ProviderData[];    // Provider-specific info

  // Methods
  getIdToken(forceRefresh?: boolean): Promise<string>;
  getIdTokenResult(forceRefresh?: boolean): Promise<IdTokenResult>;
};
Example: 
const firebaseCredential = Proview.auth.FirebaseAuthStrategy({
  apiKey: 'your-firebase-api-key',
  authDomain: 'your-project.firebaseapp.com',
  projectId: 'your-firebase-project-id',
});

const scheduler = Proview.scheduler.init({
  dsn: 'project-dsn',
  projectId: 'project-123',
  credential: firebaseCredential,
});

// Access user properties globally
const user = Proview.user;
console.log(user.uid);
console.log(user.email);
console.log(user.displayName);
console.log(user.emailVerified);

// Get ID token
const idToken = await user.getIdToken();

// Force refresh token
const freshToken = await user.getIdToken(true);

​
Firebase Authentication

​
Proview.auth.FirebaseAuthStrategy(config)

Creates a Firebase authentication credential for use with the Proview SDK modules. Input 
type FirebaseAuthStrategyConfig = {
  token: string;  // Required: Firebase authentication token
};
Returns — FirebaseAuthStrategy A credential object that can be passed to any Proview SDK module initialization. Example: 
// Initialize Firebase credential with token
const firebaseCredential = Proview.auth.FirebaseAuthStrategy({
  token: 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...',
});

// Use with scheduler module
const scheduler = Proview.scheduler.init({
  dsn: 'project-dsn',
  projectId: 'project-123',
  credential: firebaseCredential,
});

  interviewId: string;
  reason?: string;
};
PromisePromise<SchedulerState>
Callback(error: SchedulerError | null, state?: SchedulerState | null) => void

  locale?: string;

  // 'sdk' — the SDK renders its own error UI.
  // 'host' — errors are surfaced via the 'session.error' event for the host app to handle.
  errorMode?: 'sdk' | 'host';

  mountMode:
    | { mode: 'inline'; containerId: string }
    | { mode: 'sidebar'; containerId: string; width?: number }
    | { mode: 'modal'; containerId: string; closeOnBackdrop?: boolean; title?: string };

    participantId: string;
    destroyedAt: string;
  };
};

​
destroy()

Cleans up the scheduler session and all event listeners. Call mounted.unmount() first if the UI is still mounted.

​
Callback Signature

All async methods accept an optional callback as the last argument. The callback uses a Node.js-style error-first signature. 
type MeetingStateCallback = (error: SchedulerError | null, state?: SchedulerState | null) => void;
type MeetingsCallback = (error: SchedulerError | null, meetings?: MeetingSummary[]) => void;
Either style works: 
// Promise
const state = await scheduler.acceptMeeting(payload);

// Callback
scheduler.acceptMeeting(payload, (error, state) => {
  if (error) return;
  // handle updated state
});
