Changelog

v4.22.0 (Mar 26, 2026)

Features

Weekly Do-Not-Disturb Schedule

Added support for per-day weekly DND scheduling. You can now configure different DND time windows for each day of the week, replacing the previous single-time window DND setting.

New methods:

setWeeklyDoNotDisturb(weeklyDndSchedules, timezone?) — Sets a weekly DND schedule
getWeeklyDoNotDisturb() — Gets the current weekly DND schedule
clearWeeklyDoNotDisturb() — Clears the weekly DND schedule

New types:

DndSchedule — Model class for managing per-day DND time windows
DndSchedules — Partial<Record<DayOfWeek, DndTimeWindow[]>>
DndTimeWindow — { startHour, startMin, endHour, endMin }
DndSchedulePreference — { doNotDisturbOn, dndSchedules?, timezone? }
DayOfWeek — Enum (sunday | monday | ... | saturday)

Deprecated

setDoNotDisturb() — Use setWeeklyDoNotDisturb() instead.
getDoNotDisturb() — Use getWeeklyDoNotDisturb() instead.
DoNotDisturbPreference — Use DndSchedulePreference instead.

Usage Examples

Set a weekly DND schedule

import { DndSchedule, DayOfWeek } from '@sendbird/chat';

const dndSchedule = new DndSchedule();

// Set weekdays to 22:00 ~ 23:59
dndSchedule.setWeekdays([
  { startHour: 22, startMin: 0, endHour: 23, endMin: 59 },
]);

// Set weekends to full-day DND
dndSchedule.setFullDay([DayOfWeek.SATURDAY, DayOfWeek.SUNDAY]);

const preference = await sb.setWeeklyDoNotDisturb(dndSchedule, 'Asia/Seoul');

Get current weekly DND schedule

const preference = await sb.getWeeklyDoNotDisturb();

console.log(preference.doNotDisturbOn); // true
console.log(preference.timezone);       // 'Asia/Seoul'
console.log(preference.dndSchedules);
// DndSchedule {
//   monday:    [{ startHour: 22, startMin: 0, endHour: 23, endMin: 59 }],
//   tuesday:   [{ startHour: 22, startMin: 0, endHour: 23, endMin: 59 }],
//   wednesday: [{ startHour: 22, startMin: 0, endHour: 23, endMin: 59 }],
//   thursday:  [{ startHour: 22, startMin: 0, endHour: 23, endMin: 59 }],
//   friday:    [{ startHour: 22, startMin: 0, endHour: 23, endMin: 59 }],
//   saturday:  [{ startHour: 0, startMin: 0, endHour: 23, endMin: 59 }],
//   sunday:    [{ startHour: 0, startMin: 0, endHour: 23, endMin: 59 }],
// }

Clear weekly DND schedule

await sb.clearWeeklyDoNotDisturb();

Migration from deprecated DND

// Before (deprecated)
await sb.setDoNotDisturb(true, 22, 0, 8, 0, 'Asia/Seoul');

// After
const dndSchedule = new DndSchedule();
dndSchedule.setWeekdays([
  { starHour: 0, startMin: 0, endHour: 8, endMin: 0 },
  { startHour: 22, startMin: 0, endHour: 23, endMin: 59 },
]);
await sb.setWeeklyDoNotDisturb(dndSchedule, 'Asia/Seoul');

Migration Notes

Important: When you call setWeeklyDoNotDisturb, any existing DND schedule configured via the deprecated setDoNotDisturb will be reset and replaced by the new weekly schedule. The two settings are mutually exclusive — once the weekly DND schedule is set, the previous DND configuration will no longer be in effect.

v4.20.0 (Sep 25, 2025)

Improvements

Added onConnectionDelayed callback to ConnectionHandler A new callback method that is invoked when the server is overloaded. This callback provides information about the delay time before automatic reconnection. After the delayed time period, the SDK automatically initiates reconnection and triggers the callback sequence: onReconnectStarted → onReconnectSucceeded

  sb.addConnectionHandler('connection-handler-key', new ConnectionHandler({
    onConnected: (userId: string) => {
      /** A callback for when SendbirdChat is connected. */
    },
    onReconnectStarted: () => {
      /** A callback for when SendbirdChat tries to reconnect. */
    },
    onReconnectSucceeded: () => {
      /** A callback for when connection is reestablished. */
    },
    onReconnectFailed: () => {
      /** A callback for when reconnection is failed. */
    },
    onDisconnected: () => {
      /** A callback for when SendbirdChat is disconnected. */
    },
    onConnectionDelayed: (retryAfterTime: number /* second */) => {
      /** A callback for when connection is delayed. */
            
      // Example: Show user-friendly message
      // showNotification(`Server is busy. Reconnecting in ${retryAfterTime} seconds...`);
    }
  }));

Added SendbirdErrorCode.DELAYED_CONNECTING error code A new error code that is thrown when the server is overloaded and connection is delayed. Provides detailed information about the delay through the error.detail property.

  try {
    await sb.connect(USER_ID, AUTH_TOKEN);
  } catch(error) {
    if (error.code === SendbirdErrorCode.DELAYED_CONNECTING) {
      console.log('error message', error.message);

      // detail info
      const detailInfo = JSON.parse(error.detail);
      console.log('retryAfterTime', detailInfo.retry_after);     // Delay time in seconds
      console.log('reasonCode', detailInfo.reason_code);         // Server reason code
      console.log('message', detailInfo.message);               // Detailed error message
      
      // Handle delayed connection appropriately
      // The SDK will automatically retry after the specified delay time
    }
  }

Error Detail Properties:

retry_after: The delay time in seconds before automatic reconnection
reason_code: Server-provided reason code for the delay
message: Detailed error message explaining the delay

Clients will now receive MessageCollectionHandler.onChannelUpdated() with GroupChannelContext.GroupChannelEventSource.EVENT_CHANNEL_UNMUTED when an user is unmuted after their muted duration has expired, on top of explict unmute calls. This now means that you can easily transition user’s experience and allow them to chat even more seamlessly. Note that this is a MessageCollections only feature! We recommend all of our clients to give it a try if you haven’t

Added DB size related properties in LocalCacheConfig

const localCacheConfig: LocalCacheConfig = new LocalCacheConfig({
   maxSize: 256,
   clearOrder: CachedDataClearOrder.MESSAGE_COLLECTION_ACCESSED_AT,
});

v4.4.0 (Feb 24, 2023)

Features

Disconnect Websocket only

When you call sb.disconnect, it disconnects the WebSocket and clears local cache. You can think of it as logging out.

In some cases, you need to only disconnect the WebSocket. You can now do it by calling sb.disconnectWebSocket. It only disconnects the WebSocket and preserves the local cache.

sb.disconnectWebSocket();

To connect again after disconnecting with disconnectWebSocket(), use sb.connect().

const user = await sb.connect(userId: userId);

Added appStateToggleEnabled param

Added SendbirdChatParams.appStateToggleEnabled which can be used to optionally disable internal control of Websocket connection on document.visibilityState change

v4.3.0 (Feb 01, 2023)

Features

Participant class in Open Channel

Participant is a new interface for User who joined Open Channel. It's optimized for scalability and contains much lighter information about the User than a Member in Group Channel. Now clients can implement Open Channels easier in SDK with more built-in capabilities. You can compare how Member, Participant, and User are different here

Participant holds essential information about the participant like below. They contain their muted status (is_muted) on top of basic User information

class Participant extends User {
  readonly isMuted: boolean;
}

ParticipantListQuery.next() now returns Promise<Participant[]>
For backward compatibility, the return type remains as Promise<User[]>, but the return value can be casted into Promise<Participant[]>

v4.2.9 (Feb 01, 2023)

Features

Added SendbirdChatOptions.sessionTokenRefreshTimeout. You can now set longer timeout value for session token expire. (Default: 60s, Maximum: 1800s). This means that Sendbird SDK will wait longer for your new session token, making it easier for you to reconnect to our service.

Features

Pinned Message 📌

Pinned Message is released. You can now maintain a special set of messages (up to 10 per channel) that you want everyone in the channel to share. It can be anything from announcements, surveys, upcoming events, and any many more. Pin your messages and never miss them! Stay tuned for updates as we are rolling out more exciting features and see below for exact specifications:point_down:

Specification

Pin when sending a message
- UserMessageCreateParams.isPinnedMessage: boolean = false
- FileMessageCreateParams.isPinnedMessage: boolean = false
Pin existing message
- GroupChannel.pinMessage(messageId: number): Promise<void>
Unpin a message
- GroupChannel.unpinMessage(messageId: number): Promise<void>
Pinned messages
- GroupChannel.lastPinnedMessage: BaseMessage = null
- GroupChannel.pinnedMessageIds: number[] = []

We strongly recommend using Collections (Message, Channel) to implement Pinned Messages as it would automatically take care of numerous events out of the box when messages are created, updated, and deleted.
