• Bug-fix in sending a message.

• Bug-fixes

What's new in version 4?

Overall

• No callback. Use Promise.

// v3
sb.connect(userId, (err, user) => {});

// v4
const user = await sb.connect(userId);

• Treeshaking applied. The classes, interfaces, enums, types come to be import-able with treeshaking. See SDK reference page for detailed list of exports.

// v3
sb.GroupChannel
sb.LogLevel
...

// v4
import { LogLevel } from '@sendbird/chat';
import { GroupChannel } from '@sendbird/groupChannel';
...

• static object relocation.

* Should declare GroupChannelModule in SendbirdChat.init().
** Should declare OpenChannelModule in SendbirdChat.init().

New features

• Added onConnected(), onDisconnected() to ConnectionHandler.

Changes

• Changed initialization interface.

// v3
import SendBird from 'sendbird';
import AsyncStorage from '@react-native-async-storage/async-storage';

const sb = new SendBird({
  appId: APP_ID,
  localCacheEnabled: true,
});
sb.setLogLevel(sb.LogLevel.WARN);
sb.appVersion = APP_VERSION;
sb.Options.useMemberAsMessageSender = true;

// only for React Native
sb.useAsyncStorageAsDatabase(AsyncStorage);

// v4
import SendbirdChat, {
  SendbirdChatOptions,
  Loglevel
} from '@sendbird/chat';
import AsyncStorage from '@react-native-async-storage/async-storage';

const sb = SendbirdChat.init({
  appId: APP_ID,
  appVersion: APP_VERSION,
  modules,
  options: new SendbirdChatOptions({
		useMemberAsMessageSender: true,
	}),
  logLevel: LogLevel.WARN,
  localCacheEnabled: true,
  useAsyncStorageStore: AsyncStorage, // only for React Native
});

• Replaced ChannelHandler to GroupChannelHandler and OpenChannelHandler

// v3
const channelHandler = new sb.ChannelHandler();
channelHandler.onChannelChanged = (channel) => {
	...
};
sb.addChannelHandler(EVENT_ID, channelHandler);
sb.removeChannelHandler(EVENT_ID);

// v4
import { GroupChannelHandler } from '@sendbird/chat/groupChannel';

const channelHandler = new GroupChannelHandler({
	onChannelChanged: (channel) => {
		...
	},
});
sb.groupChannel.addGroupChannelHandler(EVENT_ID, channelHandler);
sb.groupChannel.removeGroupChannelHandler(EVENT_ID);

• No builder pattern for Collections.

// v3
const groupChannelFilter = new sb.GroupChannelFilter();
const gc = sb.GroupChannel.createGroupChannelCollection()
  .setOrder(sb.GroupChannelCollection.GroupChannelOrder.LATEST_LAST_MESSAGE)
  .setFilter(groupChannelFilter)
  .build();

const messageFilter = new sb.MessageFilter();
const mc = channel.createMessageCollection()
  .setFilter(messageFilter)
  .setStartingPoint(startingPoint)
  .build();

// v4
import {
	GroupChannelFilter,
	GroupChannelListOrder
} from '@sendbird/chat/groupChannel';
import { MessageFilter } from '@sendbird/chat/message';

const groupChannelFilter = new GroupChannelFilter();
const gc = sb.groupChannel.createGroupChannelCollection({
	filter: groupChannelFilter,
	order: GroupChannelListOrder.LATEST_LAST_MESSAGE,
});

const messageFilter = new MessageFilter();
const mc = channel.createMessageCollection({
	filter: messageFilter,
	startingPoint: Date.now(),
});

• Changed sb.updateCurrentUserInfo() to take UserUpdateParams as a parameter.

// v3
sb.updateCurrentUserInfo(NICKNAME, PROFILE_URL);
sb.updateCurrentUserInfoWithProfileImage(NICKNAME, PROFILE_IMAGE);

// v4
import { UserUpdateParams } from '@sendbird/chat';

const params = new UserUpdateParams({
	nickname: NICKNAME,
	profileUrl: PROFILE_URL,
	// or you can put a file as `profileImage` to upload the profile
});
sb.updateCurrentUserInfo(params);
// no sb.updateCurrentUserInfoWithProfileImage()

• Changed sb.getUnreadItemCount() to take UnreadItemCountParams as a parameter.

// v3
sb.getUnreadItemCount(KEYS);

// v4
const params = new UnreadItemCountParams({
	keys: KEYS,
});
sb.getUnreadItemCount(params);

• Changed sb.getTotalUnreadMessageCount() to take TotalUnreadMessageCountParams as a parameter.

// v3
sb.getTotalUnreadMessageCount(CHANNEL_CUSTOM_TYPES);
// no super channel filter support

// v4
const params = new TotalUnreadMessageCountParams({
	channelCustomTypesFilter: CHANNEL_CUSTOM_TYPES,
	superChannelFilter: SUPER_CHANNEL_FILTER,
});
sb.getTotalUnreadMessageCount(params);

• Changed sendUserMessage() and sendFileMessage() interface to chain the callbacks for pending/failed/succeeded messages.

// v3
const pendingMessage = channel.sendUserMessage(params, (err, message) => {
	if (err) {
		// message is a failed message
	} else {
		// message is a succeeded message
	}
});

// v4
channel.sendUserMessage(params)
	.onPending((pendingMessage: UserMessage) => {})
	.onFailed((err: Error, failedMessage: UserMessage) => {})
	.onSucceeded((succeededMessage: UserMessage) => {});

• Separated update params from create params.

// v3
GroupChannelParams // both for create/update
OpenChannelParams // both for create/update
UserMessageParams // both for send/update
FileMessageParams // both for send/update

// v4
GroupChannelCreateParams
GroupChannelUpdateParams
OpenChannelCreateParams
OpenChannelUpdateParams
UserMessageCreateParams
UserMessageUpdateParams
FileMessageCreateParams
FileMessageUpdateParams

• Changed to accept initial properties in ~Params constructors.

// v3
const params = new sb.UserMessageParams();
params.message = 'message';

// v4
import { UserMessageParams } from '@sendbird/chat/message';

const params = new UserMessageCreateParams({
	message: 'message',
});

// or you can still use it as v3
const params = new UserMessageCreateParams();
params.message = 'message';

• Changed to accept properties in ~Query constructors. The query properties are immutable later on.

// v3
const query = sb.GroupChannel.createMyGroupChannelListQuery();
query.customTypesFilter = ['a', 'b'];
query.order = 'latest_last_message';

// v4
import { GroupChannelListOrder } from '@sendbird/chat/groupChannel';

const query = sb.groupChannel.createMyGroupChannelListQuery({
	customTypesFilter: ['a', 'b'],
	order: GroupChannelListOrder.LATEST_LAST_MESSAGE,
});
query.customTypesFilter = ['a', 'b']; // ERROR! IMMUTABLE PROPERTY!

• Changed buildFromSerializedData() paths.

// v3
sb.AdminMessage.buildFromSerializedData()
sb.FileMessage.buildFromSerializedData()
sb.UserMessage.buildFromSerializedData()
sb.Sender.buildFromSerializedData()

sb.GroupChannel.buildFromSerializedData()
sb.GroupChannelListQuery.buildFromSerializedData()
sb.Member.buildFromSerializedData()

sb.OpenChannel.buildFromSerializedData()

sb.User.buildFromSerializedData()

// v4
sb.message.buildMessageFromSerializedData() // admin/file/user altogether
sb.message.buildSenderFromSerializedData()

sb.groupChannel.buildGroupChannelFromSerializedData()
sb.groupChannel.buildGroupChannelListQueryFromSerializedData()
sb.groupChannel.buildMemberFromSerializedData()

sb.openChannel.buildOpenChannelFromSerializedData()

sb.buildUserFromSerializedData()

• Turned some getter functions to read-only properties.

// v3
SendBird.getInstance()
sb.getApplicationId()
sb.getConnectionState()
sb.getLastConnectedAt()
channel.isGroupChannel()
channel.isOpenChannel()
channel.getCachedMetaData()
message.isUserMessage()
message.isFileMessage()
message.isAdminMessage()
message.isResendable()

// v4
SendbirdChat.instance
sb.appId
sb.connectionState
sb.lastConnectedAt
channel.isGroupChannel
channel.isOpenChannel
channel.cachedMetaData
message.isUserMessage
message.isFileMessage
message.isAdminMessage
message.isResendable

• Relocations

• Renames

* But stilling meaning the token for Android.

Removes

• Removed channel.getMessagesByID().
