This month’s update brings real-time emoji reactions to the JavaScript Data API, introduces the new TalkJS Support Bot, and includes important fixes and SDK improvements across platforms.

Highlights

Emoji reactions with the JavaScript Data API

You can now access and manage real-time emoji reaction data for any message using the JavaScript Data API. TalkJS Core 1.5.0 introduces two new objects: ReactionRef, created via MessageRef.reaction, and ReactionSnapshot, available through MessageSnapshot.reactions. These allow you to subscribe to live updates on emoji reactions, see how many reactions a message has, and add or remove reactions programmatically.

This update supports both Unicode and custom emoji, with a limit of 50 distinct emojis per message.

For implementation details, check out the documentation for:

• MessageRef.reaction
• MessageSnapshot.reactions
• ReactionSnapshot
• ReactionRef

24/7 TalkJS Support Bot

Building at 2:13 a.m.? We’ve got you covered. You can now get TalkJS support 24/7 with the new TalkJS Support Bot. Whether you’re integrating TalkJS into your app or fine-tuning your chat experience, the Support Bot can instantly help with product questions, troubleshooting, and setup guidance, even outside our regular office hours (CET).

Of course, our expert human support team is still here when you need them. If you’d like to talk to a person, just hit Talk to a human and a support engineer will pick things up from there.

Other changes

Added

• Added an endpoint to add or remove emoji reactions with the REST API.

Changed

• JavaScript SDK (0.41.1): Session.user, Session.conversation, ConversationRef.message, ConversationRef.participant, and MessageRef.reaction now all perform type validation on the argument and will throw an error if you use an invalid type or an empty string.
• JavaScript Data API (1.5.1): When passing markup text to ConversationRef.send, it now ignores formatted links, action buttons, action links. Previously it parsed those nodes and tried to send them, which caused an error because users don't have permission to send those nodes.
• JavaScript Data API (1.5.0): Session.user, Session.conversation, ConversationRef.message, ConversationRef.participant, and MessageRef.reaction now all perform type validation on the argument and will throw an error if you use an invalid type or an empty string.
• JavaScript Data API (1.4.2): Changed GenericFileBlock from subtype?: undefined to subtype?: never so that type narrowing works consistently when you check subtype === "".
• Flutter SDK (0.16.0) – Breaking change: Updated Firebase dependencies. This upgrades the Firebase iOS SDK version to 12.0.0 and the Firebase Android SDK version to 34.0.0.  As a result the minSdkVersion on Android is API Level 23 (Android 6.0) and the minimum iOS version supported is iOS 15. See the Firebase Android and iOS release notes for more information.

Fixed

• JavaScript SDK (0.41.1): Fixed a bug where MessageRef.get() would always set MessageSnapshot.referencedMessage to null.
• JavaScript Data API (1.5.0): Fixed a bug where MessageRef.get() would always set MessageSnapshot.referencedMessage to null.
• Flutter SDK: Fixed a bug where, on iOS, switching focus from one input field to another would cause the webview to shift downwards. Upgrade dependencies (flutter pub upgrade) for the update to take effect.
• Fixed an issue where users on iOS using Safari would have to double tap a link for that link to open.
• Fixed a bug where exiting a fullscreen video would result in the chat jumping up or down when using the Chrome browser.
• Fixed an issue where mentions wouldn’t be preserved correctly in translated messages.

Subscribe to a user’s online status

You can now get and subscribe to real-time data on a user’s online status. TalkJS Core (1.4.0) now has  UserRef.subscribeOnline, which subscribes to a user's online status. Real-time user online status data allows you to build anything from custom chat headers to online members’ lists. 

Explore online status data →

Overview of other changes

Added

• TalkJS Core (1.3.0): Added TalkSession.subscribeConversations, which returns a windowed subscription to your most recent active conversations.

Changed

• JavaScript SDK (0.40.1) and TalkJS Core (1.4.2): Changed GenericFileBlock from subtype?: undefined to subtype?: never so that type narrowing works consistently when you check for subtype.
• React Native SDK (0.15.0): A Session component now creates a User if a user doesn’t yet exist. This means that you no longer need to mount a ConversationList or Chatbox in order for the user to be created in the backend, but can do this with only the Session component.
• React Native SDK (0.15.0): Changed that every call to getConversationBuilder() returns a new object, even if the conversation ID already exists.

Fixed

• Fixed an issue where voice messages recorded outside of the chat UI (for example, sent via the REST API) weren’t displaying correctly.
• Fixed a bug in link suppressions. You can now selectively suppress certain links, instead of having to choose between suppressing either all or no links.
• TalkJS Core (1.4.1): Fixed an error that occurred when subscribing to a single conversation while already subscribed to all conversations, or vice versa.
• React Native SDK (0.15.0): Fixed an issue where onNotificationPressed didn’t work correctly on iOS when using Firebase for push notifications.
• React Native SDK (0.15.0): Fixed a bug in iOS where sometimes the device token didn’t get registered.

Highlights

 Build your own custom inbox

You can now build your own custom inbox or message center with TalkJS. The new TalkSession.subscribeConversations method for the JavaScript Data API allows you to get real-time updates about any conversations in your app.

Read more about subscribing to conversations.

Always know who’s typing

You can now use the JavaScript Data API to subscribe to typing indicators. 

Typing indicators are time-based. That means that if a user hasn’t typed anything for 10 seconds, they automatically count as having stopped typing. This ensures that typing indicators only show up when a user is actually typing, not when they accidentally pressed a key and left the tab open. 

Email notifications in a thread

Email notifications about new messages are now threaded by conversation in most email clients. This way, your users can more easily stay on top of notification messages with a clean, organized inbox.

Overview of other changes

Added

TalkJS Core

• TalkJS Core (1.2.0): Added ConversationRef.subscribeParticipants, which returns a windowed subscription to the participants in the conversation. This allows you to build custom participants lists, or create chat UIs that react to participant changes.
• TalkJS Core (1.2.0): Added ParticipantSubscription and ParticipantActiveState.
• TalkJS Core (1.1.1): Added ConversationSnapshot.everyoneReadUntil, which is the minimum of all the participants’ readUntil values. Any messages sent on or before the readUntil timestamp have been read by all participants in the conversation, which displays that double-tick read status indicator.

JavaScript SDK

• JavaScript SDK (0.38.0): Added ConversationRef.subscribeTyping.
• JavaScript SDK (0.38.0): Added TypingSnapshot.
• JavaScript SDK (0.37.0): Added readUntil field to ConversationSnapshot.

React Native SDK

• React Native SDK (0.14.0): Add hideKeyboardAccessoryView prop to Chatbox and ConversationList. When set to true it removes the accessory view (^ ˅ and Done) from the top of the iOS keyboard. The default value is false.

Changed

• TalkJS Core (1.2.0): Improved startup time by sending queued requests faster when you first open the connection.
• ⚠️ React Native SDK (0.14.0): To support React Native 0.79, this version drops support for CommonJS source files. The package now only ships with ESM source files. (breaking change)

Fixed

• React Native SDK (0.13.2): Fix setPushRegistration and unsetPushRegistration methods not working.
• Fixed an issue where, under certain conditions, the emoji picker didn’t display selected skin tones correctly.

Use a custom sender address for notifications

You can now use a custom sender address for email notifications. 

Previously, email notifications would be sent from a randomly generated address, such as jbvxkmldkrihi.mjh4b43vrl4m3tfhh455l2vwcr@r.talkjs.com. If you recently signed up, then by default all email notifications are sent by the much friendlier address notifications@r.talkjs.com. 

Are you using a custom email domain? Then you can also configure the local part of the sender address (the part before the @-symbol) directly from the details page of your email domain to change the settings.

Would you also like to use a custom email address for notifications? Get in touch to enable a custom email address for notifications for your project.

Overview of other changes

Added

• TalkJS Core (1.0.0): Initial release. The @talkjs/core package is stable and you can confidently use it to read, update, and subscribe to all your chat messaging data. Backward-compatibility guaranteed.
• TalkJS Core (1.0.1): Exported types for GenericFileMetadata, AudioFileMetadata, ImageFileMetadata, VideoFileMetadata, and VoiceRecordingFileMetadata. 
• JavaScript SDK (0.37.0): Added a new messages marker (readUntil), to show users where they left off in a conversation.
• JavaScript SDK (0.36.0): Added support for a new way of creating a session, using userId: string instead of the me: Talk.User parameter.
• Added support for localizing the chat UI into Icelandic (is-IS). Is your preferred language still missing? Get in touch to get it added.

Changed

• JavaScript SDK (0.36.0): Updated the email and phone fields when creating or editing a user. These fields now accept a string in addition to string[]. If you pass a single string, it gets converted to a single-element array.
• Flutter SDK (0.15.1): Upgraded talkjs_flutter_inappwebview dependency. 

Fixed

• React Native SDK (0.13.1): Fixed an issue where, on iOS, opening the keyboard would intermittently add extra padding.
• Fixed an issue where emojis used in messages would be rendered differently from emojis used in the emoji reactions.

Security

• Fixed an issue where, using the JavaScript Data API, under certain conditions, users could perform calls that should have been restricted to app administrators.

Chat UI components ✨ preview  ✨

TalkJS chat UI components (‘Components v2’) are now in preview and safe to use in production. 

Chat UI components give you ultimate flexibility to control the appearance and behavior of your chat. You can use the components with a ready-to-go pre-built theme, or customize your theme to get the exact look and feel you want.

Currently components are available for a chatbox UI with a range of basic features, which is continuously expanding. 

To work with chat UI components, you’ll need to combine the following two packages:

• @talkjs/components — a library that provides both React components and web components that you can use with any frontend framework, such as Angular, Vue, or Svelte.
• @talkjs/theme-default — a package with the default theme for @talkjs/components which lets you display a chat with any frontend framework. The default theme is fully open source, and you can fork and customize it to fit your own brand. See the default theme Github repository.

Use one of the dedicated getting started guides for chat UI components:

• JavaScript getting started guide →
• React getting started guide →
• Next.js getting started guide →
• Angular getting started guide →
• Vue getting started guide →
• Svelte getting started guide →

Real-time messaging data

You can now read, update, and subscribe to all your chat messaging data—no chat UI needed. This means that you can bring your own fully custom-built chat UI, and let TalkJS take care of the rest.

To work with real-time chat data, you have the following two options:

• Realtime API, part of the JavaScript SDK
• @talkjs/core, a standalone package now available on NPM

Want to get started directly? Here are some guides: 

• 1:1 chat getting started guide →
• Group chat getting started guide →

Overview of other changes

Added

• JavaScript SDK (0.35.0): Added ConversationRef.subscribe to be able to subscribe to a conversation with the Realtime API. 
• React Native SDK (0.13.0): The keyboardVerticalOffset prop is now also used in Android. This is part of the fix to ensure proper keyboard behaviour on apps targeting Android 15 and above. The default value on Android is 55 + StatusBar.currentHeight.

Changed

• React Native SDK (0.13.0): Updated dependencies.

Deprecated

• JavaScript SDK (0.35.0): Removed ConversationSnapshot.lastMessageAt. Use ConversationSnapshot.lastMessage.createdAt instead.

Fixed

• React Native SDK (0.13.0): Fixed keyboard issues on Android 15 that arose due to Android's enforcement of edge-to-edge.
• React Native SDK (0.13.0): Fixed internal event subscriptions not being cleaned up properly on re-renders.

Manage themes with the REST API

You can now manage your chat UI themes using the TalkJS REST API. This includes the options to create, update, delete or export a theme. You can directly edit themes for your test environment. Once you’re happy with the updates, copy the changes to your live environment, and you’re all set.

Managing your themes through the REST API makes it easier to work with themes across multiple projects, or keep themes in your code base and update them when deploying.

Overview of other changes

Added

• Added an endpoint to the REST API that allows you to get a user's notification reply-to email address for a conversation. Any emails sent to that email address appear in the conversation as being sent by the user.
• JavaScript SDK (0.34.0): Added SendMessageParams that can be passed to ConversationRef.send to send a message by specifying its content directly. This allows you to send text messages with manually-specified formatting, in addition to file attachments and locations.
• JavaScript SDK (0.34.0): Added EditMessageParams that can be passed to MessageRef.edit to edit a message by specifying its content directly. This allows you to edit text messages with manually-specified formatting, in addition to file attachments and locations.
• JavaScript SDK (0.34.0): Added Session.uploadFile and file-subtype-specific variants. This returns a FileToken that you can use in SendMessageParams or EditMessageParams.
• React Native SDK (0.12.0): Added the customEmojis prop to Chatbox and ConversationList. This prop adds a set of custom emoji images to the emoji picker, the emoji autocompleter, and emoji reactions. It allows users to send and receive custom emojis.
• React Native SDK (0.12.0): Added keyboardVerticalOffset prop to Chatbox. This prop is basically identical to the one passed to KeyboardAvoidingView. The default value is 90. Note that the keyboardVerticalOffset prop is only used in iOS to fix an iOS bug. On Android, the KeyboardAvoidingView component isn’t available.

Changed

• React Native SDK (0.12.1): Changed the default value for the keyboardVerticalOffset to 95.

Fixed

• Fixed an issue where user IDs weren’t sent correctly, which caused user mentions to break.
• Fixed an issue where user mentions would break when the user ID contained a pipe (|) character.
• React Native SDK (0.12.1): Fixed a bug in iOS when New Architecture is enabled, where the whole UI would be scrollable when the keyboard is open.
• React Native SDK (0.12.0): Fixed a bug in iOS, where opening the keyboard would cause the ChatHeader or the top messages to get hidden. 
• React Native SDK (0.12.0): Fixed the TypeError: _messageField.getTextResolver is not a function (it is undefined), js engine: hermes. error.
• React Native SDK (0.12.0): Fixed ref methods not working when called after a delay.

Overview of changes

Added

• Added the option to set a referencedMessageId when importing messages with the REST API.
• Added a hook that triggers an event when a message is translated in real-time. The event includes the message ID, original message text (text), detected language, and the translated message text (translatedText). This way, you can store both the original and translated versions of the message.

Fixed

• Fixed an issue where, in the Realtime API, publishes would not be received correctly if the conversation ID of the conversation you’re subscribed to contained special characters.
• Fixed a bug where notifications didn’t pick up correctly on edits to a message text.

Highlights

Multiple webhooks

You can now add multiple webhooks to your app. Webhooks can be useful as part of a chatbot interface, to inspect messages as they happen, or to trigger custom domain-specific actions.

To add a new webhook, go to the Settings page of your TalkJS dashboard, and select Add new webhook. Add your webhook URL, select the events that you’d like to subscribe to, and save your settings. 

You can add up to three webhooks if you’re on the Growth plan or higher.

Read more about webhooks.

Accessibility improvements

Chat just got more accessible:

• Keyboard navigation: The scrollable area in the chatbox is now keyboard accessible. The area can get focus, so you can use your keyboard’s up and down arrow keys to scroll the container.
• Screen reader: If you’ve got a conversation in focus and someone sends a new message into that conversation, a screen reader will read out the new message.

Do you have more accessibility wishes for your chat? We’d love to hear from you! Get in touch.

Messages on the Realtime API

Messages are available on the Realtime API. That means that you can now access a continuous, up-to-date flow of data related to messages, without needing to send repeated requests or open a chat UI. 

Version 0.31.0 of the JavaScript SDK adds the following:

• ConversationRef.message: Reference to a message in a given conversation.
• ConversationRef.subscribeMessages: Subscribe to the messages in a given conversation.
• MessageSubscription: Subscription to the messages in a given conversation. 
• MessageRef: Reference to a message.
• MessageSnapshot.content: The main body of a given message. The body is a list of content blocks with entity trees, which means that you can render the message exactly as it would appear in the frontend.
• ReferencedMessageSnapshot: Snapshot of a message's attributes at a given moment in time. 
• MessageSnapshot.referencedMessage: Snapshot of the message that the given message is a reply to, or null if this message is not a reply. 
• EditMessageParams, SendMessageParams, and MessageActiveState.

Overview of other changes

Added

• JavaScript SDK (0.31.0): Added ConversationRef.send.
• JavaScript SDK (0.30.0): Added ConversationSnapshot.lastMessage.
• JavaScript SDK (0.29.0): Added ConversationRef.markAsRead and ConversationRef.markAsUnread

Changed

• React SDK (0.1.10): Allow null as a value for the conversationId prop.
• Changed the options for @mentioning a user. Only users who are a current participant in a conversation can be mentioned in that conversation. You can no longer mention guest users. 

Deprecated
