Upgrading from V3

Add a required threadList prop

Add a threadList prop on Channel component which wraps the Thread component as following:

(This change is only required if you use Thread component within your application. )

<Channel channel={channel} thread={thread} threadList>
  <Thread />
</Channel>

For implementing double tap handler on message bubble please take a look at example mentioned in our docs

messageActions

This prop is used to customize the actions available on message within overlay. Its a function which return an array of actions. Since v4 this function won't receive following properties on its parameter object:

• canModifyMessage
• mutesEnabled
• reactionsEnabled
• threadRepliesEnabled
• quotedRepliesEnabled

Instead a new property has been added - ownCapabilities to check availability of feature for current user Please check the docs of message action customization for example.

Mute User Action

In v4 "Mute User" action has been removed from the SDK, since its not exactly an action on message and is not the right place for it. If the business requirements of application needs this message action, then please add it by customizing messageActions prop as mentioned in example

Update The Dependencies

• Since v4, peer dependency react-native-blur has been removed from the SDK. Blur background of overlay has been replaced with opacity based background instead. So unless this dependency is used explicitly within application, it can be safely removed.

yarn remove react-native-blur
npx pod-install

• Minimum required version of stream-chat is 6.0.0. So if you have installed stream-chat dependency explicitly, please make sure to upgrade it to v6.0.0

Refactor Typescript Generics

Until now StreamChat client and Chat components accepted 7 different generics as provided in following example:

const client = StreamChat.getInstance<
  ChatAttachment,
  ChatChannel,
  CustomCommands,
  ChatEvent,
  UserMessage,
  CustomReaction,
  ChatUser
>('YOUR_API_KEY', 'API_KEY_SECRET');

These 7 generics have been replaced now with 1 single generics for the sake of simplicity.

const client = StreamChat.getInstance<StreamChatGenerics>('YOUR_API_KEY');

Please refer to our typescript guide for details of Generics.

Whats new in v4?

Optimized Image Attachments

Gallery component has been revamped to be more performant and more responsive. Heavy images have been one of the crucial reasons previously for slow performance on low RAM devices. In this version of SDK, resized version of images (depending on DP ratio of device) will be requested from new CDN to avoid rendering heavy images on UI.

Also previously all the image attachments used to be rendered in fixed size container, which was not ideal for portrait or landscape images since user won't be able to see a cropped image on UI. In this version, we render images in dynamic size container, depending on aspect ratio of image.

Refactor Generics to a Single Generic

The Typescript generics have been simplified to a single generic instead of 7 different generics (as in previous versions of SDK) which should be passed to the component or StreamChat client.

const client = StreamChat.getInstance<StreamChatGenerics>('YOUR_API_KEY');

where StreamChatGenerics can be defined as;

type StreamChatGenerics = {
  attachmentType: LocalAttachmentType;
  channelType: LocalChannelType;
  commandType: LocalCommandType;
  eventType: LocalEventType;
  messageType: LocalMessageType;
  reactionType: LocalReactionType;
  userType: LocalUserType;
};

note

LocalAttachmentType, LocalChannelType etc. are type definitions for their respective key as per your application types necessities.

Eg:

type LocalAttachmentType = {
  file_size?: number;
  mime_type?: string;
};
type LocalChannelType = Record<string, unknown>;
type LocalCommandType = string;
type LocalEventType = Record<string, unknown>;
type LocalMessageType = Record<string, unknown>;
type LocalReactionType = Record<string, unknown>;
type LocalUserType = {
  image?: string;
};

A separate guide has been added to documentation for details of Generics

Slow Mode Feature

Slow mode helps reduce noise on a channel by limiting users to a maximum of 1 message per cool-down interval. Slow mode is disabled by default and can be enabled/disabled via the Dashboard, using the Chat Explorer.

For more details, please check the documentation for slow mode

When cool-down interval kicks in, SendButton (to send message) will be replaced with a countdown timer This countdown timer can be customized using a prop on Channel component - CooldownTimer

Pin Message Feature

"Pin Message" action within overlay now allows you to pin a message to channel.

Pinned messages allow users to highlight important messages, make announcements, or temporarily promote content. Pinning a message is, by default, restricted to certain user roles, but this is flexible. Each channel can have multiple pinned messages and these can be created or updated with or without an expiration.

To read more about how to retrieve pinned messages or search pinned messages, please read the documentation on Pinned Messages.

Better Handling Of User Capabilities on Channel

Features and UI components have been configured to use the own_capabilities returned by backend, improving the consistency between SDK features and permissions/config/settings applied on application. To read more about these capabilities, please follow the documentation - https://getstream.io/chat/docs/javascript/channel_capabilities/

You can override these capabilities on UI level by providing overrideOwnCapabilities prop on Channel component:

<Channel
  overrideOwnCapabilities={{
    banChannelMembers: false, // hides "Block User" message action.
    deleteAnyMessage: false, // hides "Delete Message" action for received message.
    deleteOwnMessage: false, // hides "Delete Message" action for own message.
    flagMessage: false, // hides "Flag Message" action.
    pinMessage: false, // hides "Pin Message" action.
    quoteMessage: false, // hides "Reply" action.
    readEvents: false, // hides read receipts.
    sendLinks: false, // disallows sending links with message.
    sendMessage: false, // disallows sending a message.
    sendReaction: false, // hides reaction selector in overlay.
    sendReply: false, // hides "Thread Reply" message action.
    sendTypingEvents: false, // disallows sending typing events
    updateAnyMessage: false, // hides "Edit Message" action for received message.
    updateOwnMessage: false, // hides "Edit Message" action for own message.
    uploadFile: false, // hides attach button on message input.
  }}

Replaced next/prev Giphy Navigation With Shuffle

Next and previous buttons on Giphy message have been replaced with shuffle button, since Giphy API doesn't support pagination and it resulted into confusing user experience.

Dropped BlurView Package

• Background for the overlay which opens up when user long-presses on a message, has been replaced with opacity based background instead of BlurView #874 This dependency caused a lot of issues due to its underlying native BlurView dependency. Thus we decided to get rid of this hurdle by dropping this peer dependency.

Performance Improvements

• react-native-reanimated based animations have been removed from Message component for performance reason #987.
  • Long press animation on message UI has been removed
  • animatedLongPress prop has been removed from Channel component.
• Redundant HTTP requests for downloading image attachments have been fixed #1010
• Performance intensive legacy image viewer behaviour has been turned off by default #1006. Please take a look at description of the prop legacyImageViewerSwipeBehaviour for details.

Improved Customizability

Autocomplete suggestions

The following three new props on Channel component allows customizing UI for autocomplete suggestions list:

• AutoCompleteSuggestionHeader
• AutoCompleteSuggestionList
• AutoCompleteSuggestionItem

For details please read the docs on Autocomplete Suggestions Customizations

Message Actions

Following two new props on OverlayProvider component allows customizing UI for message actions:

• MessageActionList
• MessageActionListItem

Additionally styles of the message actions can be customized using following new theme keys:

overlay: {
  messageActions: {
    actionContainer: ViewStyle;
    icon: ViewStyle;
    title: TextStyle;
  }
}

A separate guide has been added to documentation for details of How To Customize Message Actions UI

Deleted Messages

Visibility of deleted messages can be configured using a prop deletedMessagesVisibilityType on Channel component.

<Channel deletedMessagesVisibilityType={'never'} />

This prop has following 4 possible values:

• always: The deleted messages in the channel will be visible to both the sender and receiver.
• never: The deleted messages will not be visible to anyone.
• sender: The deleted messages in the channel will only be visible to sender.
• receiver: The deleted messages in the channel will only be visible to receiver.

Overlay Reactions User Avatar

Avatar of users (shown in OverlayReactions component) who reacted to message, can now be customized using a prop on OverlayProvide component - OverlayReactionsAvatar.

Fixes Issues

Warning about virtualized List wrapped inside ScrollView

Following warning from v3 of SDK has been fixed now.

This warning was a result of ScrollView wrapped around FlatList inside overlay. Purpose of the wrapping ScrollView was to make overlay scroll-able in case message text content is too long. The UX and this warning has been fixed by removing the ScrollView and truncating the text content of message within overlay. You can customize the truncation length of message text by providing a prop messageTextNumberOfLines (number) on OverlayProvider.

<OverlayProvider messageTextNumberOfLines={300}>{/** child components */}</OverlayProvider>

ChannelList ignores updated filters if API call is in progress

https://github.com/GetStream/stream-chat-react-native/issues/678

If the screen which creates the filter prop for ChannelList quickly renders two or more different filters, only the first filter will be fetched, with the subsequent filters being discarded. This results in a stale ChannelList until it is manually refreshed.

Failed messages can't be deleted

Delete action on failed message would result in error previously, which has been fixed in this release.

Mentioned users get removed after editing message

https://github.com/GetStream/stream-chat-react-native/issues/1023

URL parsing crashes the app when text contains special character

Application would crash if the message text contains special character and someone replies to the message. This has been fixed in this release.
