feat(MessageComposer): make composer previews a configurable set - #3365
Depends on GetStream/stream-chat-js#1970 (the vite example removes stream-chat's poll-only middleware, which that PR exports). It is released in 10.0.0-rc.29, which this PR now depends on.
🎯 Goal
Let integrators choose, order and extend what the message composer shows above the input, the same way they already can with the message action set. Let an app attach a poll to the message being composed, let a message bubble show a poll next to its text and attachments, and let each message action decide for itself which messages it applies to.
🛠 Implementation details
Composer previews
MessageComposerPreviews renders defaultMessageComposerPreviewSet: edited message, quoted message, voice recording, attachments, link previews, location. Each item is { type, Component, isVisible(params) }, where params is MessageComposerPreviewVisibilityFilterParams. The area renders only when an item is visible.
A custom set goes in through the messageComposerPreviewSet prop, or the MessageComposerPreviews slot in WithComponents.
useMessageComposerPreviewState() and useMessageComposerPreviewSetFilter() are exported for custom containers. EditedMessagePreview and GeolocationPreview are now exported from the root.
MessageComposerPreviewVisibilityFilterParams include pollId, so a custom item can show the poll the composer holds.
Poll in the composer: no SDK preview
The SDK ships no composer poll preview, because the other SDKs don't support one. stream-chat sends a poll together with the message's text and attachments once the app removes the poll-only middleware; showing that poll in the composer is the app's own preview item.
The vite example ships one (examples/vite/src/ComposerPreviews/PollPreview.tsx): question, option count with the first options, and the poll's settings. Remove detaches the poll without deleting it, because the composer cannot tell whether it created the poll or whether it was already sent (e.g. a poll_id restored from a draft). A poll that no longer exists is detached, so the send does not fail on it. The preview is hidden while editing.
Poll creation dialog
The dialog footer is now the PollCreationDialogControls slot, so an app can replace "Send poll" with, for example, an "Attach poll" button.
Message bubble
MessageBubbleContent renders defaultMessageBubbleContentSet (quoted message, poll, attachments, text), customizable through a prop or the MessageBubbleContent slot. Items get MessageBubbleContentVisibilityFilterParams.
A message with a poll now also renders its text and attachments, and gets the str-chat__message--has-poll class.
The bubble content reads the live MessageContext, so updates the memoized MessageUI skips (e.g. the translation toggle) still reach it. Props passed to MessageUI override the context for the whole message.
Message actions
Each action item can carry isVisible(params), with MessageActionVisibilityFilterParams ({ isMyMessage, isThreadReply, message }). It holds the action's own rule about the message, and replacing the item changes it.
The default set's rules move from useBaseMessageActionSetFilter onto their items: edit hides for a poll message (poll_id) or a giphy, copyMessageText for a message without text, download for one without a downloadable attachment.
Item rules apply to failed messages too.
isVisible can only hide an action. Capabilities, features enabled on the server and the message's status stay in the base filter and cannot be overridden.
useUserRole().canEdit is now the update permission alone, the same check the base filter makes.
Example app (vite)
Settings › Composer: drag-and-drop the preview sections. Removing a section also removes the way into it (for example, without Files the attachment selector drops the File option).
Settings › Message: order the bubble's content.
While the Poll preview is on, the poll dialog attaches the poll, the poll is sent with the message, and poll messages can be edited.
Known limitations
A restored draft carries only poll_id, and client.polls is not reactive. A poll preview therefore has to fetch an uncached poll itself and keep it in its own state; the example does this as a stopgap. Fixing it needs a reactive poll store in stream-chat: REACT-1494, out of scope for v15.0.
Remove in a poll preview only detaches the poll. A poll created in the composer and then removed stays on the server, unused.
Docs
ai-docs/ai-migration-v14-v15.md covers the preview set, the poll dialog footer slot with an "Attach poll" example and an app-side poll preview item, the message bubble content set, and the action items' isVisible rules.
Docs pages to update: "Message composer UI" (the preview set, the attach example with an app's poll preview), the message UI page (the bubble content set) and the message actions page (isVisible, canEdit).
Tests: previews (order, edit mode, custom and removed items, slot, no default poll preview, a custom item showing the composer's poll, axe), the translation toggle reaching the bubble text, bubble content (order, classes, custom set, axe), the dialog footer slot, action visibility rules (poll edit hidden by default, also for a failed local poll message, and allowed by a replaced item, params passed to isVisible, no override of capabilities, rules applied with the base filter off), and canEdit for a poll message.
💥 Breaking changes
For the merge commit:
BREAKING CHANGE: useUserRole(message).canEdit is now the update permission alone
(update-any-message, or update-own-message on the user's own message). It no
longer excludes poll messages and giphies. A custom UI that gated an edit button
on it and wants that rule adds `!message.poll_id && message.command !== 'giphy'`.
BREAKING CHANGE: the edit, copyMessageText and download rules about the message
moved from useBaseMessageActionSetFilter onto the items of
defaultMessageActionSet as isVisible. A hand-written edit, copyMessageText or
download item without isVisible now shows wherever the base filter allows it,
e.g. edit on a poll message the user may update. Copy the default item's
isVisible to keep the rule. Item isVisible rules also apply when
disableBaseMessageActionSetFilter is set, which previously returned the set
unfiltered, and to failed messages: a poll message or giphy that failed to send
for a network reason no longer offers Edit.
BREAKING CHANGE: a message with a poll renders its text and attachments too, and
the quoted message now renders above the poll instead of below it. Such a
message gets str-chat__message--has-poll and no longer gets
str-chat__message--has-single-attachment.
BREAKING CHANGE: custom AttachmentPreviewList, VoiceRecordingPreviewSlot and
LinkPreviewList components mount only while their item in
defaultMessageComposerPreviewSet is visible: attachments while the composer holds
an attachment other than a voice recording, voiceRecording while it holds a voice
recording, linkPreviews while a link preview is loading or loaded. Previously they
mounted whenever the preview area showed. A custom component that also renders
something else (a location, a poll, an empty or upload state) replaces its item
with one whose isVisible covers it.

Summary by CodeRabbit
New Features
Reorder, enable, or disable message-bubble content and composer preview sections from the settings panel.
Preview and remove attached polls in the composer, or attach a poll to a composed message without sending it separately.
Customize message-bubble content, composer previews, and poll-creation controls.
Configure per-action visibility rules; these can hide actions but cannot override permission or other base checks.
Edit, copy, and download actions reflect message content and type.
Poll preview labels are available in English, German, and Italian.
Documentation
Added a migration guide covering action visibility, message-bubble content, composer previews, and poll workflows.
…add a poll preview
MessageComposerPreviews renders a messageComposerPreviewSet, modelled on
MessageActions' messageActionSet: each item has a type, a Component and an
isVisible rule read from composer state. The preview area renders when any
item is visible. defaultMessageComposerPreviewSet keeps today's previews and
order and adds a poll preview, shown while messageComposer.state.pollId holds
a poll not sent yet (not while editing).
Integrators install their own set through the new MessageComposerPreviews
component slot. PollPreview is a slot too. EditedMessagePreview,
GeolocationPreview, PollPreview, useMessageComposerPreviewSetFilter and
useMessageComposerPreviewState are exported from the root.

Closes REACT-1430
…e settings
Settings -> Composer lists the composer's preview sections, built from
defaultMessageComposerPreviewSet. Drag a section (or use its arrows) to
reorder it, or switch it off. The composer renders the result through the
MessageComposerPreviews slot.
A removed section also removes the composer's way into it: Files drops the
selector's File option and rejects dropped or pasted files, Poll and Location
turn off their composer config, Link previews stops scraping, Voice recording
hides the record button, and Quoted and Edited message drop the Quote and
Edit actions.
Refs REACT-1441
PollCreationDialog renders its footer through the new
PollCreationDialogControls slot. PollCreationDialogControls and its props
type are exported, so an integrator can replace only the footer, e.g. with
a button that calls messageComposer.createPoll() without send() to attach
the poll to the message being composed.
Refs REACT-1441
…s shown
While Settings -> Composer shows the Poll preview section, the vite app
replaces the poll creation dialog's footer through the
PollCreationDialogControls slot with an "Attach poll" button. It calls
messageComposer.createPoll() without send(), so the poll waits in the
composer's preview and goes out with the next message.
Refs REACT-1441
…ist in the poll preview
The poll preview shows the option count, names the first three options and
counts the rest (a poll holds up to 100), and lists the poll's settings as
tags: multiple votes or the vote limit, anonymous voting, user-suggested
options and comments.
Refs REACT-1441
MessageUI renders the bubble's content through MessageBubbleContent, which
renders a messageBubbleContentSet modelled on the composer preview set: each
item has a type, a Component and an isVisible rule read from the message.
defaultMessageBubbleContentSet renders the quoted message, poll,
attachments and text. Integrators install their own set through the new
MessageBubbleContent component slot.
A message that quotes and carries a poll now shows the quote first (v14
rendered the poll above it). The root element gets
str-chat__message--has-poll, and a message with a poll no longer gets
str-chat__message--has-single-attachment.
Refs REACT-1441
…settings tab
Settings -> Message lists defaultMessageBubbleContentSet (quoted message,
poll, attachments, text) to drag or arrow into order. The vite app renders
the result through the MessageBubbleContent slot.
The drag-and-drop list is shared with Settings -> Composer as
SortableSectionList.
Refs REACT-1441
…ttachments
While Settings -> Composer shows the Poll preview, the composer setup removes
stream-chat's poll-only composition step, so the poll the dialog attaches goes
out with the message instead of as a message of its own. Turning the section
off puts the step back in its place. The migration guide's "Attach poll"
example shows the same.

It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
This change adds configurable visibility rules for message actions, ordered message-bubble content, and ordered composer previews. It adds a poll preview and configurable poll-dialog controls. The Vite example adds settings to reorder and disable these sections and applies them to message and composer components.
Action-set items support isVisible predicates. The base filter applies these rules alongside capability and message-state checks. Default actions define message-specific visibility rules, and canEdit now reflects update capabilities without excluding polls or Giphy messages.
Message content renders from an ordered set with visibility predicates. The default order places quoted messages before polls. Poll messages receive a poll-specific class.
The composer renders ordered preview sets, including a poll preview. Poll dialog controls can attach a poll to the composer without sending a message.
Example settings and integration examples/vite/src/*
The Vite example adds sortable settings for preview sections and message-bubble content. It applies these settings to composer features, message actions, attachment selection, and component overrides.

…y rule
Message action set items take an optional isVisible, called with
MessageActionVisibilityFilterParams ({ isMyMessage, isThreadReply, message }).
The default set's rules about the message move from
useBaseMessageActionSetFilter onto their items: edit hides for a poll message
or a giphy, copyMessageText for a message without text, download for one
without a downloadable attachment. Replacing an item changes its rule.
isVisible can only hide an action: the base filter still checks capabilities,
server-enabled features and the message's status. Item rules also apply when
disableBaseMessageActionSetFilter is set. useUserRole().canEdit is now the
update permission alone, the same check the base filter makes.
The composer preview and bubble content isVisible arguments are renamed to
match: MessageComposerPreviewVisibilityFilterParams and
MessageBubbleContentVisibilityFilterParams.
The vite example allows editing poll messages while the Poll preview is shown.

The edited-message preview item wrapped its preview in a second
str-chat__message-composer-previews element, so the edit preview got the
area's padding twice and sat further in than the quoted-message preview.

Import of POLLONLYCOMPOSITIONMIDDLEWAREID breaks the Vite build on the locked stream-chat version.
17-31: Major · Data Integrity & Integration · Quick win
Import of POLL_ONLY_COMPOSITION_MIDDLEWARE_ID breaks the Vite build on the locked stream-chat version.
The Vite example imports POLL_ONLY_COMPOSITION_MIDDLEWARE_ID from stream-chat. The locked version, 10.0.0-rc.25, does not export that name. tsc reports a missing named export, so tsc && vite build fails. The root examples:build script runs this workspace, so it fails too. The PR description already states that this build fails until a stream-chat release includes the export.
Do not merge this example change until one of these is true:
The example resolves a stream-chat version that exports POLL_ONLY_COMPOSITION_MIDDLEWARE_ID. Update examples/vite/package.json and yarn.lock to that version.
The example no longer imports the constant from the locked version.
The STREAM_CHAT_JS_PATH override does not prevent the failure for the ordinary build. It applies only when a developer points the build at a local SDK checkout.

Resolve the missing export in the Vite example by either updating its

## Description of the changes, What, Why and How?
**What:** an integrator can now send a composer's poll together with the
message's text, attachments and quoted message. Until now the poll
always went out as a message of its own, and the drafted text stayed in
the composer.
**How:** remove the poll-only step from the composer's composition
chain. This adds no new config field or composer method:
```ts
import { POLL_ONLY_COMPOSITION_MIDDLEWARE_ID } from 'stream-chat';
client.config.setSetupFunction('messageComposer', ({ composer }) => {
composer.compositionMiddlewareExecutor.remove(POLL_ONLY_COMPOSITION_MIDDLEWARE_ID);
});
```
- `createPollOnlyCompositionMiddleware` and
`POLL_ONLY_COMPOSITION_MIDDLEWARE_ID` are now exported, so the step can
be removed and put back.
- The default `retainCompositionOnSubmit` keeps the composer's contents
for a poll only while the poll-only step is installed. Removing the step
therefore also clears the composer after the send. Without this, the
attachments step would leave out attachments the composer keeps, so they
would not be sent.
- With the default chain, behaviour is the same as before.
**Why:** the React SDK's composer can show an attached poll next to the
text and attachments (GetStream/stream-chat-react#3365). This makes it
possible to send them as one message.
## Changelog
- Export the poll-only composition middleware and its id, so a composer
can send its poll with the message's text and attachments by removing
the middleware.

Review notes: the inline comments below cover implicit regressions I found. The first one (MessageUI's inner MessageProvider) breaks the translation toggle, so I'd treat it as blocking. The rest are smaller behaviour changes or cleanups.
The reason will be displayed to describe this comment to others. Learn more.
Regression: the translation toggle no longer updates the text. This provider takes its value from the memoized MessageUI props. areMessageUIPropsEqual compares only the message and a few layout props, not translationView. When the user clicks "Show original" / "Show translation", Message.tsx updates the outer context, MemoizedMessageUI bails out, and MessageText (which now reads this inner context) keeps the old text. The indicator outside the bubble still flips its label.
The same staleness applies to every other field the comparator skips: renderText, onMentionsClickMessage / onMentionsHoverMessage, unsafeHTML, handleAction and isMessageAIGenerated, for QuotedMessage, MessageText, StreamedMessageText, Poll and the Attachment tree. AGENTS.md: "A prop it does not check will not re-render a message." Before this change these components read the live outer context.
Suggestion: drop the inner provider so the default items read the outer MessageContext. Apart from direct MessageUI prop overrides it already holds the same values. If those overrides have to reach the bubble, pass them some other way, or add the fields to the comparator.
The reason will be displayed to describe this comment to others. Learn more.
Fixed in 7ce7637: the inner provider is gone, so the bubble content reads the live outer MessageContext. Props passed directly to MessageUI are now provided outside the memo (only when there are any), so they still override the context. Added a test that toggles the translation view and expects the original text; it fails on the previous code.
The reason will be displayed to describe this comment to others. Learn more.
Undocumented change for custom slot overrides. Before, AttachmentPreviewList, VoiceRecordingPreviewSlot and LinkPreviewList from ComponentContext rendered whenever the previews area showed. Now they render only when these default rules match. A custom AttachmentPreviewList that renders the location or poll returned by useAttachmentsForPreview(), or shows an empty or upload state, silently stops mounting. Worth a line under Breaking changes, or a note in the migration guide.

Documented in 7ce7637: a bullet in the migration guide's composer previews section, with a snippet that widens the attachments item's isVisible, and a BREAKING CHANGE footer in the PR description.

Minor: with the default PollCreationDialogControls, createPoll() sets pollId, then the controls await send(), and send() awaits compose() before releaseSubmittedComposition(). During that gap this item is visible, so the previews area can mount and unmount around every default "Send poll". That's a possible layout jump in apps that never opt into attaching polls.
The reason will be displayed to describe this comment to others. Learn more.
Right, pollId is set before send() releases it, so the poll item mounts and unmounts. Whether that paints depends on whether any composition middleware waits on more than microtasks; with the default chain it is likely committed and removed before a frame. A proper fix is hiding the poll item while the poll-only step is installed, which needs POLL_ONLY_COMPOSITION_MIDDLEWARE_ID from the next stream-chat release. I'll follow up once that's in.
The reason will be displayed to describe this comment to others. Learn more.
Follow-up: as of 6ba38ab the SDK has no default poll preview item (the preview moved to the vite example), so a default "Send poll" no longer mounts anything in the preview area.
The reason will be displayed to describe this comment to others. Learn more.
This checks message.poll, while the bubble set, str-chat__message--has-poll and the composer all key on poll_id. A local or failed poll message, as built by the poll-only middleware, has only poll_id. After a network failure, the base filter's error branch allows edit and this rule passes, so Edit shows on a poll message. !message.poll_id would be consistent.
The reason will be displayed to describe this comment to others. Learn more.
Fixed in 7ce7637: the rule now checks !message.poll_id, and the migration guide and canEdit note say the same. Added a test with a network-failed local poll message (poll_id only): Delete shows, Edit does not.
The reason will be displayed to describe this comment to others. Learn more.
Behaviour change for failed messages: isVisible now runs after the message.error branch. That branch used to allow edit for any network-failed message. Now a network-failed /giphy message loses Edit because of message.command !== 'giphy'. If that's intended, it's worth adding to the Breaking changes notes, which currently cover only the hand-written-item and disableBaseMessageActionSetFilter cases.
The reason will be displayed to describe this comment to others. Learn more.
Intended: item rules describe the message's content, so they apply to failed messages too. A network-failed poll message or giphy no longer offers Edit. Added to the migration guide in 7ce7637 and to the BREAKING CHANGE footer in the PR description.
The reason will be displayed to describe this comment to others. Learn more.
Remove only detaches pollId, and the poll already created on the server stays orphaned, one per attach-then-remove cycle. Also, if the fetch above fails (for example, a restored draft points to a deleted poll), the catch leaves a bare "Poll" placeholder with no retry or error, and the send then fails on the server because of the stale poll_id. Consider showing an error state, or clearing pollId when getPoll reports the poll as not found.
The reason will be displayed to describe this comment to others. Learn more.
Fixed in 7ce7637: Remove also deletes the poll (it was never sent; a failed delete is ignored). If fetching the poll reports it does not exist (code 16 / 404), the composer detaches it so the send does not fail. Other fetch errors keep the placeholder, since the poll may still be fine. Tests cover all three.
The reason will be displayed to describe this comment to others. Learn more.
Follow-up: I reverted the delete in 82a78fa. The composer cannot tell whether it created the poll or whether the poll was sent (a poll_id restored from a draft can point to a published one), so deleting could remove a published poll and its votes. An orphaned unsent poll is the lesser problem. Deleting it safely needs stream-chat to track the polls a composer creates. Detaching a poll that no longer exists stays.
The reason will be displayed to describe this comment to others. Learn more.
Follow-up: in 6ba38ab the poll preview moved to the vite example, since the other SDKs ship none; the SDK keeps pollId in the preview params for an app's own item. The example still fetches an uncached poll itself, because a restored draft carries only poll_id and client.polls is not reactive. That is listed as a known limitation in the PR description; a reactive poll store in stream-chat is the follow-up.
The reason will be displayed to describe this comment to others. Learn more.
Nit (perf): no default rule reads customData, but this subscription re-renders MessageComposerPreviews and re-runs every isVisible on each customDataManager update. Apps that write custom data on each keystroke now pay for that. The default preview components also subscribe again to the same stores (attachments, editedMessage, location). Maybe leave customData to custom items that need it?
The reason will be displayed to describe this comment to others. Learn more.
customData is the documented way to drive a custom item's visibility from app state (see the custom-preview test and the migration guide), and without it a custom item has no reactive input. The cost is one shallow selector and the isVisible checks. I'd keep it; the default components' own subscriptions are independent of it.

Merge order: createPollOnlyCompositionMiddleware and POLL_ONLY_COMPOSITION_MIDDLEWARE_ID exist only after GetStream/stream-chat-js#1970. yarn examples:build runs in CI, so this needs a stream-chat release and a dependency bump before it can go green. Nothing in this diff bumps stream-chat yet.
The reason will be displayed to describe this comment to others. Learn more.
Agreed. GetStream/stream-chat-js#1970 is merged but came after rc.28, and POLL_ONLY_COMPOSITION_MIDDLEWARE_ID isn't in rc.28. This PR needs rc.29 and a bump before merging.
The reason will be displayed to describe this comment to others. Learn more.
Follow-up: done. 7962e1b bumps stream-chat to 10.0.0-rc.29 (root and examples/vite), which includes GetStream/stream-chat-js#1970 and exports POLL_ONLY_COMPOSITION_MIDDLEWARE_ID and createPollOnlyCompositionMiddleware. 6f254c7 bumps @stream-io/state-store to 1.2.0 to match it, so there is a single copy and yarn types is clean again.
…le and poll preview
Read the live MessageContext in the bubble content, so a translation toggle the
memo comparator skips still updates the text. Props passed to MessageUI are
provided outside the memo.
Key the edit action's rule on poll_id, which a failed local poll message carries.
Delete the unsent poll when its preview is removed, and detach a poll that no
longer exists. Document the custom preview slot gating and the edit rule on
failed messages.
The composer cannot tell whether it created the poll or whether the poll was
sent (a poll_id restored from a draft), so deleting it could remove a published
poll and its votes. Also drop the default location item in the migration
guide's custom AttachmentPreviewList example, so the location is not shown
twice.

Update the workspace peer range in yarn.lock.
The root package requires stream-chat: ^10.0.0-rc.29, but the workspace lock metadata still records ^10.0.0-rc.28. The PR check runs Yarn in CI, where immutable installation can reject this mismatch.

src/components/Message/MessageUI.tsx:104-106 Minor · Functional Correctness · Quick win
Use the cached poll when setting the poll layout flag.
When the poll cache has no entry, the poll content renders null, but hasPoll still disables the single-attachment layout. A single-Giphy message can therefore keep the wrong padding and display text that the attachment-only layout hides.

Catch createPoll() failures in the migration example.
messageComposer.createPoll() can reject after reporting the creation failure. The documented async click handler does not catch that rejection. Match the default control and the Vite example.
Suggested fix
onClick={async () => {
// The poll waits in `messageComposer.state.pollId` and goes out with the message.
- await messageComposer.createPoll();- close();+ try {+ await messageComposer.createPoll();+ close();+ } catch {+ // `createPoll()` already reported the failure as a notification.+ }

The other SDKs ship no composer poll preview, so the React SDK does not either. The LLC still
sends a poll with the message's text and attachments once the poll-only middleware is removed;
showing that poll in the composer is the app's own preview item.
The example's PollPreview fetches a restored draft's poll itself: a draft carries only `poll_id`,
and `client.polls` is not reactive yet.
BREAKING CHANGE: `PollPreview` is no longer exported, the `PollPreview` component slot is removed,
and `defaultMessageComposerPreviewSet` has no `poll` item. An app that attaches polls to the
message adds its own preview item (see ai-docs/ai-migration-v14-v15.md).

feat(MessageComposer): make composer previews a configurable set and add a poll preview
feat(MessageComposer): make composer previews a configurable set
Nov 2, 2026
yarn.lock peer range (package.json:147): already fixed in 7962e1b. The workspace entry records stream-chat: ^10.0.0-rc.29.
hasPoll and the poll cache (MessageUI.tsx:104-106): keeping poll_id. The bubble content set, str-chat__message--has-poll and the Edit rule all key on poll_id, which a reviewer asked for. A message with poll_id and no cached poll is rare (a poll created in the composer is cached on creation), and the only effect is the single-attachment layout not applying.
createPoll() failures in the migration example: fixed in bef2e43. The handler closes the dialog and wraps createPoll() in try/catch, as the default controls and the Vite example do.
@MartinCupela Thanks for the clarification. I checked the current PR files.
Peer range: Confirmed. The workspace peer entry in yarn.lock matches package.json: stream-chat: ^10.0.0-rc.29.
hasPoll: Agreed. Keep poll_id as the signal. The cache-based change I suggested is unnecessary for the intended layout behavior. I withdraw that recommendation.
Migration example: Confirmed. The handler calls close() and catches failures from await messageComposer.createPoll().
No further changes are needed for these three comments. This was a source inspection; I did not run tests.

## [15.0.0-rc.4](v15.0.0-rc.3...v15.0.0-rc.4) (2026-11-06)
### ⚠ BREAKING CHANGES
* props and ComponentContext keys that had no effect are removed, nine slots are typed without props, and overrides of several slots render in more places.
- `additionalMessageComposerProps` is removed from `Message`, `MessageList`, `VirtualizedMessageList` and `VirtuosoContext`. It did nothing in v14; delete it. If the props were meant for the composer, pass them to the `MessageComposer` you render.
- `MessageReactions.reverse`, `MessageReactionsDetail.sort` and `MessageReactionsDetail.dialogId` are removed, and `MessageUI` no longer passes `reverse` to a `MessageReactions` override. Order reaction types with `sortReactions` and reacting users with `reactionDetailsSort`; the detail's dialog id is `MessageReactionsDetail.getDialogId({ messageId })`.
- `MessageComposer` no longer takes `emojiSearchIndex` or `parent`, the `emojiSearchIndex` override key is removed, and `useMessageComposerContext()` no longer returns `emojiSearchIndex`, `parent` or `audioRecordingConfig`. For emoji autocomplete, register `createTextComposerEmojiMiddleware(SearchIndex)` from `stream-chat-react/emojis` in a `client.config.setSetupFunction('messageComposer', ...)`.
- `WithDragAndDropUpload.acceptedFiles` is removed. Set the accepted types on the composer config, `attachments.acceptedFiles`.
- `ChannelListItem.activeChannel` is removed. A custom `ChannelListItemUI` reads `active`, or compares the app's own selected channel with its `channel`.
- `ChatView.entityInferrers`, the `ChatViewEntityInferer` type and `useChatViewContext().entityInferers` are removed.
- The `AttachmentPreviewList`, `MessageComposerUI`, `MessageEditedIndicator`, `MessageStatus`, `NotificationAnnouncer`, `QuotedMessagePreview`, `SearchSourceResultList`, `TextareaComposer` and `VoiceRecordingPreviewSlot` slots are typed `React.ComponentType` without props, because the SDK renders them without props. Rendering one from `useComponentContext()` with props, or an override with required props, no longer compiles; render the exported component with its props inside the override.
- Overrides of `FileDragAndDropContent`, `BaseImage`, `LoadingIndicator`, `Timestamp`, `Avatar`, `DateSeparator`, `Gallery` and `FileSizeIndicator` now also render where the SDK rendered the default directly: link previews, video thumbnails, galleries, quoted messages, load-more buttons, poll vote lists, thread list items, user search results, the thread's parent message, composer previews and channel detail lists. To keep the default in one place, wrap it in `WithComponents` with the exported default.
See ai-docs/v15-breaking-changes.md (BC-105 to BC-109, BC-033) and ai-docs/ai-migration-v14-v15.md.
* **ChannelListHeader:** ComponentContext.HeaderEndContent is removed. Pass the content
as EndContent to ChannelListHeader / ThreadListHeader instead, by registering a
component that renders the header with it under the ChannelListHeader or
ThreadListHeader key. One component no longer fills both headers.
* **ChannelListHeader:** list-header content renders whenever it is set. HeaderEndContent
showed only while a channel (channel list) or a thread (thread list) was open;
content that should keep that behavior returns null while
useWorkspaceNavigation().openChannels / openThreads is empty. See BC-099 in
ai-docs/v15-breaking-changes.md and "List headers: HeaderEndContent becomes an
EndContent prop" in ai-docs/ai-migration-v14-v15.md.
* **ChannelDetail:** ChannelMembersHeaderActionItem.component is renamed to
Component, matching the message and channel-list action sets.
* **ChannelDetail:** the 'menu' placement of a channel members header action is
renamed to 'dropdown'. A 'menu' item is no longer rendered.
* **ChannelDetail:** the HeaderActionsMenuTrigger prop (on ChannelMembersView and
ChannelMembersHeaderActionsProps), DefaultHeaderActionsMenuTrigger and
ChannelMembersHeaderActionsMenuTriggerProps are removed. The menu trigger is a
{ Component, placement: 'quick-dropdown-toggle' } item in headerActionSet: a
forwardRef button that receives the ref the menu anchors to, aria-expanded and
onClick, and spreads them. defaultChannelMembersHeaderActionSet starts with
DefaultChannelMembersHeaderActions.QuickDropdownToggle; a set without a toggle
item renders no dropdown menu.
* **ChannelDetail:** dropdown header actions no longer receive a closeMenu prop.
They read closeMenu from useContextMenuContext().
* **ChannelDetail:** a header action's filter is renamed to isVisible, typed with
ChannelMembersHeaderActionVisibilityFilterParams and called with { channel }, as
on message actions. A leftover filter is ignored, so the action it hid shows to
every user.
* **ChannelDetail:** ChannelMembersHeaderActionItem is a union whose
quick-dropdown-toggle member has no type or isVisible, and
ChannelMembersHeaderActionPlacement includes 'quick-dropdown-toggle'. Narrow an
item (e.g. 'type' in item) before reading type.
* **ChannelDetail:** a custom HeaderActions renders the set's quick-dropdown-toggle
item itself and filters the set with useBaseChannelMembersHeaderActionSetFilter.
It renders the dropdown items in a ContextMenu opened with
useDialogOnNearestManager, using an id unique to the component instance. See
BC-098 in ai-docs/v15-breaking-changes.md and "The channel members header action
set uses the shared action names" in ai-docs/ai-migration-v14-v15.md.
* **TypingIndicator:** translations of `typing.twoUsers` must use
`{{ firstUser }}` and `{{ secondUser }}` instead of `{{ typing }}`, for example
'{{ firstUser }} und {{ secondUser }} schreiben'. A translation that keeps
`{{ typing }}` still compiles but shows the literal text `{{ typing }}`.
See BC-100 in ai-docs/v15-breaking-changes.md and "Keys whose values changed"
in ai-docs/i18n-v15-migration.md.
* unused exports and the transliterate dependency are removed, and stream-chat-react now types channel custom data for apps.
- `Root` and `Header` are no longer exported from the package root. They are the parts of `Alert`; use `Alert.Root` and `Alert.Header`.
- `UploadIcon`, `BinIcon`, `PauseIcon` and `PlayIcon` are removed. Copy the SVG into the app, or use `IconPlus` / `IconAttachment`, `IconDelete`, `IconPauseFill` and `IconPlayFill` from the v15 icon set.
- `@stream-io/transliterate` is no longer an optional dependency. Apps that import it must add it to their own dependencies. For mention search, pass a `transliterate` function to stream-chat's mentions middleware.
- Importing `stream-chat-react` now types `channel.data.custom.name` and `.image` (`string | undefined`). Delete the app's own `name` / `image` declarations on `CustomChannelData`; a declaration with another type overrides the SDK's under `skipLibCheck` and fails with TS2430 without it.
- `DefaultChannelData` no longer has `subtitle` or `team`. Declare them on `CustomChannelData` if the app stores them under `custom`; read the channel's team from `channel.data.team`.
- The translation key `messageComposer.icons.attachFiles.text` is removed.
See ai-docs/v15-breaking-changes.md (BC-101) and ai-docs/ai-migration-v14-v15.md.
* **Message:** Removed the initialMessage property from message props and context. Use the new hook to identify thread-parent messages.
* **ChannelDetail:** outside a modal, the ChannelDetail views render no close
button unless ChannelDetail or ChannelDetailProvider gets onClose. They used to
render a close button that did nothing.
* **ChannelDetail:** ChannelDetail calls onLayoutChange on every layout change. It
used to ignore the prop.
* **AttachmentSelector:** SimpleAttachmentSelector, and the plain upload button AttachmentSelector renders when File is its only action, follow the composer's File rule instead of the upload-file capability alone. They appear without upload-file when attachments.customCdn is set, are hidden when attachments are disabled (the channel type's uploads flag is off without customCdn, or the client sets attachments.enabled: false), and are disabled once the message holds maxNumberOfFilesPerMessage files. At that limit the menu's File item also stays, disabled, where v14 hid it. See BC-065 in ai-docs/v15-breaking-changes.md and "Attachment and poll availability" in ai-docs/ai-migration-v14-v15.md.
* deprecated message, mention and list APIs are removed.
- `renderText(text, mentionedUsers, options)` is now `renderText(text, options)`, and `RenderTextFunction` is `(text, options)`. Pass mentions as `options.messageMentionEntities`, built with `getRenderTextMentionEntities(message)`.
- Custom mention renderers get `node.mentionedEntity` instead of `node.mentionedUser`.
- `onMentionsClick` / `onMentionsHover` are called with `(event, message)`; the `mentioned_users` argument and the `MentionedUserEventHandler` type are removed (use `CustomMentionHandler`). Read the clicked mention from the target's `data-user-id` / `data-mention-id`.
- `MessageContextValue.onMentionsClickMessage` / `onMentionsHoverMessage` and the handlers from `useMentionsHandler` are `undefined` unless `onMentionsClick` / `onMentionsHover` is passed. Mentions are interactive only when a click handler is set.
- `mentionsMarkdownPlugin` and `createMentionPluginAndDisplayTextSet` take mention entities only, not `UserResponse[]`.
- `useUserRole` is renamed `useMessagePermissions(message)`, and it no longer returns `isAdmin`, `isModerator` or `isOwner`; gate on the `can*` flags or `useChannelCapabilities()`.
- `disableQuotedMessages` is removed from `MessageList`, `Message` and `useMessagePermissions`. To hide quoting, pass a `messageActionSet` without the `quote` item through the `MessageActions` slot.
- `VirtualizedMessageList` drops `defaultItemHeight`, `overscan` and `scrollSeekPlaceHolder`; pass them through `additionalVirtuosoProps`.
- `PinEnabledUserRoles` and `PinPermissions` are removed; use `useMessagePermissions(message).canPin`.
See ai-docs/v15-breaking-changes.md (BC-087 to BC-095) and ai-docs/ai-migration-v14-v15.md.
* message context and grouping API changes.
- MessageProps.threadList and MessageContextValue.threadList are removed. Detect a thread
with `!!useThreadContext()`.
- ReactionSelector.getDialogId takes only `{ messageId }`; the reaction selector dialog id
no longer has a `-thread` part. Each message list has its own dialog manager.
- MessageContextValue.endOfGroup, firstOfGroup and groupedByUser are removed. Read
`useMessageContext().groupStyles[0]` (`top`, `middle`, `bottom` or `single`).
- The str-chat__virtual-message__wrapper--end, --first and --group classes are no longer
applied. Target the list item's .str-chat__li--top / --middle / --bottom / --single.
- MessageList.noGroupByUser and VirtualizedMessageList.shouldGroupByUser are replaced by
groupByUser (defaults: true and false). VirtuosoContext.shouldGroupByUser is groupByUser.
- The groupStyles function prop of both lists is renamed getGroupStyles and is called with
one GetGroupStylesParams object: { groupByUser, maxTimeBetweenGroupedMessages, message,
nextMessage, previousMessage }. The exported getGroupStyles takes the same object, and
useEnrichedMessages takes getGroupStyles and groupByUser instead of groupStyles and
noGroupByUser.
See BC-048, BC-085 and BC-086 in ai-docs/v15-breaking-changes.md.
* **MessageComposer:** useUserRole(message).canEdit is now the update permission alone
(update-any-message, or update-own-message on the user's own message). It no
longer excludes poll messages and giphies. A custom UI that gated an edit button
on it and wants that rule adds `!message.poll_id && message.command !== 'giphy'`.
* **MessageComposer:** the edit, copyMessageText and download rules about the message
moved from useBaseMessageActionSetFilter onto the items of
defaultMessageActionSet as isVisible. A hand-written edit, copyMessageText or
download item without isVisible now shows wherever the base filter allows it,
e.g. edit on a poll message the user may update. Copy the default item's
isVisible to keep the rule. Item isVisible rules also apply when
disableBaseMessageActionSetFilter is set, which previously returned the set
unfiltered, and to failed messages: a poll message or giphy that failed to send
for a network reason no longer offers Edit.
* **MessageComposer:** a message with a poll renders its text and attachments too, and
the quoted message now renders above the poll instead of below it. Such a
message gets str-chat__message--has-poll and no longer gets
str-chat__message--has-single-attachment.
* **MessageComposer:** custom AttachmentPreviewList, VoiceRecordingPreviewSlot and
LinkPreviewList components mount only while their item in
defaultMessageComposerPreviewSet is visible: attachments while the composer holds
an attachment other than a voice recording, voiceRecording while it holds a voice
recording, linkPreviews while a link preview is loading or loaded. Previously they
mounted whenever the preview area showed. A custom component that also renders
something else (a location, a poll, an empty or upload state) replaces its item
with one whose isVisible covers it.

## [10.0.0](v9.55.0...v10.0.0) (2026-11-06)
### ⚠ BREAKING CHANGES
* release v10 from master as latest (#2004)
* `LocalAttachmentMetadata` requires only `id`. `file` and `uploadState` are
optional, so code that reads them from a `LocalAttachment` must handle `undefined`. A `file` must
come with its `uploadState`: `localMetadata: { id, file }` no longer compiles, and an attachment
in that shape from untyped code is no longer sent. An attachment with neither field (a custom type
or `giphy`) is sent as it is, takes no upload slot, and counts as content in `hasSendableData`.
* CustomCommandData is no longer exported. Delete its augmentations and imports. A leftover augmentation still compiles and has no effect, so search for the name rather than relying on tsc. An app that wants a closed set of command names declares its own union. See ai-docs/v10-breaking-changes.md#custom-data-augmentation.
* the client no longer dispatches capabilities.changed and
the name is no longer an EventType. Subscribe to channel.state instead:
channel.state.subscribeWithSelector(({ ownCapabilities }) => ({ ownCapabilities }), fn).
See ai-docs/v10-breaking-changes.md#capabilities-changed-removed.
* AttachmentManager.uploadAttachment() is removed. Retry a failed upload, or upload an attachment you built yourself such as a voice recording, with `attachmentManager.uploadFile(attachment)`. It keeps the attachment's id, fields and position, and runs the pre- and post-upload middleware, which uploadAttachment() skipped. uploadFile() does not check `isUploadEnabled`, so check it first to skip the upload as uploadAttachment() did. uploadFile() always resolves to an attachment: where a result was checked for `undefined`, check `result.localMetadata.uploadState` instead. See ai-docs/v10-breaking-changes.md#upload-attachment-removed.
* the message composer installs the command middlewares by default: createActiveCommandGuardMiddleware and createCommandStringExtractionMiddleware in the text composer chain, createCommandInjectionMiddleware in the composition chain and createDraftCommandInjectionMiddleware in the draft composition chain. Typing `/giphy cats` activates giphy and leaves `cats` in the text, and a command picked with `textComposer.setCommand()` is sent with its name. Delete your own installs of these middlewares. A UI without a command chip removes all four by id: `stream-io/text-composer/active-command-guard` and `stream-io/text-composer/command-string-extraction` from `textComposer.middlewareExecutor`, `stream-io/message-composer-middleware/command-string-injection` from `compositionMiddlewareExecutor` and `stream-io/message-composer-middleware/draft-command-string-injection` from `draftCompositionMiddlewareExecutor`. See ai-docs/v10-breaking-changes.md#composer-command-middlewares-default.
* Channel.watch() resolves with the channel instance to use (the channel, or the instance that superseded it) instead of the server response.
- watch() sends no query for a channel that is already watched and loaded (watchStatus Watching, initialized, and messagePaginator.hasResults) when it passes no options or the same options as the last successful watch() during the current watch; other options send a query. It no longer refreshes a watched channel: use channel.reload(), and load other messages through channel.messagePaginator (jumpToMessage(), toTail(), toHead()).
- A watch() while another with the same options is in flight joins it instead of sending a request.
- Aborting requestOptions.signal ends only that caller's wait; the request is cancelled once every caller waiting for it has aborted.
- Channel.ensureWatched() is removed (v10 release candidates only); call watch().
```
## Changelog
- `Channel.watch()` resolves with the channel and sends no query for a
channel already watched and loaded, unless it asks for options the
current watch was not sent with. `Channel.ensureWatched()` is removed.

* remove messageSetToAddToIfDoesNotExist and let the message paginator place every page (#1926)
* open api hot fixes (#1927)
* `StreamChatOptions` and `client.options` are removed.
`new StreamChat(key, config)` and `StreamChat.getInstance(key, config)` take
the configuration tree (`DeepPartial<InstanceConfigTree>`) as their second
argument; the `config` wrapper is dropped.
Option moves:
- `allowServerSideConnect`, `axiosRequestConfig`, `baseURL`, `browser`,
`persistUserOnConnectionFailure` -> `client.<same name>`
- `notifications` -> `client.notificationManager`
- top-level axios fields (`timeout`, `httpsAgent`, ...) ->
`client.axiosRequestConfig.<key>`
Example: `new StreamChat(key, { client: { allowServerSideConnect: true } })`.
`client.persistUserOnConnectionFailure` is no longer a field (use
`client.config.setConfig('client', { persistUserOnConnectionFailure })`);
`client.browser` and `client.node` are read-only getters.
`baseURL`, `axiosRequestConfig` and `notificationManager` are read at
construction, and the tree copies `axiosRequestConfig` instead of keeping
your object. See v9-to-v10-migration-guide-client-construction.md.
* client.activeChannels is removed; use client.channelManager.get(cid) and client.channelManager.values().
* client.hydrateActiveChannels() is renamed to client.hydrateChannels().
* client.getChannelById() and client.getChannelByMembers() are removed; use client.channel() or client.channelManager.ensure({ type, id?, data? }).
* thread.deactivate() is removed; thread.activate() returns the function that ends the activation.
* channel._disconnect() is renamed to channel.disconnect().
* channel.disconnected is removed; read the read-only channel.pendingDisposal instead, which only channel.disconnect() sets.
* when a channel created from members gets a cid another stored instance already holds, the stored instance stays, as in v9, and the new one is marked channel.supersededBy; if the new one is open and the stored one isn't, its unsent composition moves to the stored one, so UIs holding the new instance should switch to channel.supersededBy.
* channel.initialized is set by query() and create() too, not only by watch().
* channel search results are not watched; watch a result when it is opened.
* MessageSearchSource no longer watches the channels it fetches for its results; watch the channel when a result is opened, e.g. with jumpToMessage(id, { watchChannel: true }).
* adopt TS generator changes (#1896)
* reenable WS fallback (#1889)
* thread paginator and manager revamp (#1888)
* **MessageDeliveryReporter:** The `isLocalUnreadCountEnabled` client option is
removed. Use `channel.readEvents.localUnreadCountEnabled` in the
configuration service instead (see above).
* brand server-sent timestamps as TimestampNS and ship the Date guard (#1884)
* `connection.changed` is removed. Connectivity is published as two state stores
and nothing else: `client.networkConnection.state` for the device and `client.wsConnection.state`
for this client's socket. The event was silent on `closeConnection()` and two error paths, and
held a drop for five seconds; the stores are written on every transition and publish immediately.
* `client.wsConnection` is now a `WSConnection` wrapper rather than the
`StableWSConnection` itself, and is never null. The live socket is `client.wsConnection.connection`,
replaced on every connect; read `isHealthy`, `isConnecting`, `connect()` and `disconnect()` from the
wrapper. `StableWSConnection` is constructed with `{ wsConnection }` instead of `{ client }`.
* `client.defaultWSTimeout` is removed, along with the `WebSocketImpl` and
`wsUrlParams` client options. They move to the socket's configuration as `connectTimeoutMs`,
`webSocketImpl` and `urlParams`, set with `client.config.set({ client: { wsConnection: { … } } })`.
Unlike the fields and options they replace, these survive a reconnect.
* `ThreadManagerState.lastConnectionDropAt` is removed. Read
`client.wsConnection.state.lastUnhealthyAt`, which is written on every status transition,
including the `disconnect()` path the old event was silent about.
* requests that watch a channel or subscribe to presence now wait for a WebSocket
connection id instead of silently returning unwatched data. The gate is in `ApiClient._doRequest`,
so it covers every endpoint carrying `watch` or `presence`, plus `stopWatchingChannel` and
`longPoll`. With no socket open and none being established the request rejects with "No connection
id is available"; an explicit `watch: false` is still honoured, and a caller's `AbortSignal`
abandons the wait. Test fixtures that fake a connected user without a live socket will now throw.
* a UI that renders a "connection lost" banner must hold the drop itself. The
socket's store publishes drops the moment they happen, where the old event delayed them by five
seconds. `client.wsConnection.config.offlineNotificationDisplayDelayMs` (5s) is the shared value to
wait for; nothing in this package acts on it.
* `connection.recovered` is no longer dispatched when the socket drops while a
recovery is running, because every reload in it can have failed. Work keyed off that event will
correctly stop running for recoveries that recovered nothing.
* openapi related clean up (#1870)
* **SearchController:** remove InternalSearchControllerState (#1866)
* remove response date transform (#1849)
* `client.instanceConfigurationService` is replaced by `client.config`,
and the exported class `InstanceConfigurationService` is renamed to
`InstanceConfigurationRegistry`.
* `client.setInstanceConfigurationFunction()` is removed. Register
setup functions with `client.config.setSetupFunction(key, fn)`.
`client.setMessageComposerSetupFunction()` is unchanged.
* the per-class setup types are replaced by generic ones keyed by
instance. Removed: `ChannelSetupFunction`, `ChannelSetupState`,
`ChannelTearDownFunction`, `MessageComposerSetupFunction`, `MessageComposerSetupState`,
`MessageComposerTearDownFunction`, `StreamChatSetupFunction`, `StreamChatSetupState`,
`StreamChatTearDownFunction`, `ThreadSetupFunction`, `ThreadSetupState`,
`ThreadTearDownFunction`, `SetInstanceConfigurationFunctions`,
`SetInstanceConfigurationServiceStates` and `SetupFnOf`. Use `InstanceSetupFunction`,
`InstanceSetupState`, `InstanceSetupTearDownFunction` and `InstanceSetupKey`.
* `ChannelInstanceConfig` is renamed to `ChannelConfig` and
`ThreadInstanceConfig` to `ThreadConfig`.
* `Channel.getConfig()` is removed. Read the server's channel-type
configuration from `channel.serverConfig`, or the resolved configuration from
`channel.config`.
* `client.configs` is renamed to `client.channelServerConfigs` and
`client.configsStore` to `client.channelServerConfigsStore`. Keys are still cids, so
lookups translate directly. Prefer `channel.serverConfig`.
* `channel.config.commands` is renamed to
`channel.config.availableCommands`. The server owns the list, so it is read-only and
absent from the declarative configuration tree.
* `applyCommandValidatorOverride` is no longer exported. Command
validation is configured through the composer's configuration.
* `MessageComposerConfig` gains a required `polls`;
`AttachmentManagerConfig` gains required `enabled` and `customCdn`;
`LocationComposerConfig` gains a required `minShareDurationMs`. A config object
built literally must supply them.
* `linkPreviews.enabled` now defaults to `true`, where it defaulted to
`false`. It is ANDed with the channel type's `url_enrichment`, so `true` means "no
opinion, let the server decide"; the old default double-gated the feature and kept it
off even where the server had enabled it.
* server flags gate the features they describe, ANDed with the
registered value rather than the client value winning: `typingEvents` with
`typing_events`, `readEvents` with `read_events`, `attachments` with `uploads`,
`polls` with `polls`, `location` with `shared_locations`, and `linkPreviews` with
`url_enrichment`. Code that set a flag to `true` and assumed it took effect may now
find the feature off.
* setters no longer discard a write when the server is masking the
field. Previously the setter compared against the effective value, so the write was
dropped and the earlier request was honoured once the server relented. Affects
`linkPreviewsManager.enabled`, `textComposer.enabled`, `textComposer.maxLengthOnEdit`,
`textComposer.maxLengthOnSend` and `attachmentManager.maxNumberOfFilesPerMessage`.
* remove hand-written types and API wrappers (#1836)
* **i18n:** `Streami18n.init()` now rejects when i18next fails to
initialize, where it previously logged and resolved. Callers that ignore
the returned promise will see an unhandled rejection. The instance
remains usable in its degraded English form either way.
`Streami18n.brand` is removed; nothing in either UI SDK read it, and a
custom integration that recognized instances through it should compare
against its own marker or accept the instance it was handed.
* **i18n:** share the translation runtime as stream-chat/i18n (#1830)
* `ChannelManager` keeps its name but is a different class
table
Co-authored-by: Ivan Sekovanikj <31964049+isekovanic@users.noreply.github.com>
* paginator-based message storage replaces
channel.state.messages and channel.state.last_message_at. The message
list, thread replies and pinned messages are now owned by
channel.messagePaginator, thread.messagePaginator and
channel.pinnedMessagesPaginator. OpenAPI-generated clients replace the
hand-written request/response types. See
docs/breaking-changes-v14-v15.md for the full migration guide.

## [15.0.0](https://github.com/GetStream/stream-chat-react/compare/v14.12.0...v15.0.0) (2026-11-06)
### ⚠ BREAKING CHANGES
* props and ComponentContext keys that had no effect are removed, nine slots are typed without props, and overrides of several slots render in more places.
- `additionalMessageComposerProps` is removed from `Message`, `MessageList`, `VirtualizedMessageList` and `VirtuosoContext`. It did nothing in v14; delete it. If the props were meant for the composer, pass them to the `MessageComposer` you render.
- `MessageReactions.reverse`, `MessageReactionsDetail.sort` and `MessageReactionsDetail.dialogId` are removed, and `MessageUI` no longer passes `reverse` to a `MessageReactions` override. Order reaction types with `sortReactions` and reacting users with `reactionDetailsSort`; the detail's dialog id is `MessageReactionsDetail.getDialogId({ messageId })`.
- `MessageComposer` no longer takes `emojiSearchIndex` or `parent`, the `emojiSearchIndex` override key is removed, and `useMessageComposerContext()` no longer returns `emojiSearchIndex`, `parent` or `audioRecordingConfig`. For emoji autocomplete, register `createTextComposerEmojiMiddleware(SearchIndex)` from `stream-chat-react/emojis` in a `client.config.setSetupFunction('messageComposer', ...)`.
- `WithDragAndDropUpload.acceptedFiles` is removed. Set the accepted types on the composer config, `attachments.acceptedFiles`.
- `ChannelListItem.activeChannel` is removed. A custom `ChannelListItemUI` reads `active`, or compares the app's own selected channel with its `channel`.
- `ChatView.entityInferrers`, the `ChatViewEntityInferer` type and `useChatViewContext().entityInferers` are removed.
- The `AttachmentPreviewList`, `MessageComposerUI`, `MessageEditedIndicator`, `MessageStatus`, `NotificationAnnouncer`, `QuotedMessagePreview`, `SearchSourceResultList`, `TextareaComposer` and `VoiceRecordingPreviewSlot` slots are typed `React.ComponentType` without props, because the SDK renders them without props. Rendering one from `useComponentContext()` with props, or an override with required props, no longer compiles; render the exported component with its props inside the override.
- Overrides of `FileDragAndDropContent`, `BaseImage`, `LoadingIndicator`, `Timestamp`, `Avatar`, `DateSeparator`, `Gallery` and `FileSizeIndicator` now also render where the SDK rendered the default directly: link previews, video thumbnails, galleries, quoted messages, load-more buttons, poll vote lists, thread list items, user search results, the thread's parent message, composer previews and channel detail lists. To keep the default in one place, wrap it in `WithComponents` with the exported default.
See ai-docs/v15-breaking-changes.md (BC-105 to BC-109, BC-033) and ai-docs/ai-migration-v14-v15.md.
* **ChannelListHeader:** ComponentContext.HeaderEndContent is removed. Pass the content
as EndContent to ChannelListHeader / ThreadListHeader instead, by registering a
component that renders the header with it under the ChannelListHeader or
ThreadListHeader key. One component no longer fills both headers.
* **ChannelListHeader:** list-header content renders whenever it is set. HeaderEndContent
showed only while a channel (channel list) or a thread (thread list) was open;
content that should keep that behavior returns null while
useWorkspaceNavigation().openChannels / openThreads is empty. See BC-099 in
ai-docs/v15-breaking-changes.md and "List headers: HeaderEndContent becomes an
EndContent prop" in ai-docs/ai-migration-v14-v15.md.
* **ChannelDetail:** ChannelMembersHeaderActionItem.component is renamed to
Component, matching the message and channel-list action sets.
* **ChannelDetail:** the 'menu' placement of a channel members header action is
renamed to 'dropdown'. A 'menu' item is no longer rendered.
* **ChannelDetail:** the HeaderActionsMenuTrigger prop (on ChannelMembersView and
ChannelMembersHeaderActionsProps), DefaultHeaderActionsMenuTrigger and
ChannelMembersHeaderActionsMenuTriggerProps are removed. The menu trigger is a
{ Component, placement: 'quick-dropdown-toggle' } item in headerActionSet: a
forwardRef button that receives the ref the menu anchors to, aria-expanded and
onClick, and spreads them. defaultChannelMembersHeaderActionSet starts with
DefaultChannelMembersHeaderActions.QuickDropdownToggle; a set without a toggle
item renders no dropdown menu.
* **ChannelDetail:** dropdown header actions no longer receive a closeMenu prop.
They read closeMenu from useContextMenuContext().
* **ChannelDetail:** a header action's filter is renamed to isVisible, typed with
ChannelMembersHeaderActionVisibilityFilterParams and called with { channel }, as
on message actions. A leftover filter is ignored, so the action it hid shows to
every user.
* **ChannelDetail:** ChannelMembersHeaderActionItem is a union whose
quick-dropdown-toggle member has no type or isVisible, and
ChannelMembersHeaderActionPlacement includes 'quick-dropdown-toggle'. Narrow an
item (e.g. 'type' in item) before reading type.
* **ChannelDetail:** a custom HeaderActions renders the set's quick-dropdown-toggle
item itself and filters the set with useBaseChannelMembersHeaderActionSetFilter.
It renders the dropdown items in a ContextMenu opened with
useDialogOnNearestManager, using an id unique to the component instance. See
BC-098 in ai-docs/v15-breaking-changes.md and "The channel members header action
set uses the shared action names" in ai-docs/ai-migration-v14-v15.md.
* **TypingIndicator:** translations of `typing.twoUsers` must use
`{{ firstUser }}` and `{{ secondUser }}` instead of `{{ typing }}`, for example
'{{ firstUser }} und {{ secondUser }} schreiben'. A translation that keeps
`{{ typing }}` still compiles but shows the literal text `{{ typing }}`.
See BC-100 in ai-docs/v15-breaking-changes.md and "Keys whose values changed"
in ai-docs/i18n-v15-migration.md.
* unused exports and the transliterate dependency are removed, and stream-chat-react now types channel custom data for apps.
- `Root` and `Header` are no longer exported from the package root. They are the parts of `Alert`; use `Alert.Root` and `Alert.Header`.
- `UploadIcon`, `BinIcon`, `PauseIcon` and `PlayIcon` are removed. Copy the SVG into the app, or use `IconPlus` / `IconAttachment`, `IconDelete`, `IconPauseFill` and `IconPlayFill` from the v15 icon set.
- `@stream-io/transliterate` is no longer an optional dependency. Apps that import it must add it to their own dependencies. For mention search, pass a `transliterate` function to stream-chat's mentions middleware.
- Importing `stream-chat-react` now types `channel.data.custom.name` and `.image` (`string | undefined`). Delete the app's own `name` / `image` declarations on `CustomChannelData`; a declaration with another type overrides the SDK's under `skipLibCheck` and fails with TS2430 without it.
- `DefaultChannelData` no longer has `subtitle` or `team`. Declare them on `CustomChannelData` if the app stores them under `custom`; read the channel's team from `channel.data.team`.
- The translation key `messageComposer.icons.attachFiles.text` is removed.
See ai-docs/v15-breaking-changes.md (BC-101) and ai-docs/ai-migration-v14-v15.md.
* **Message:** Removed the initialMessage property from message props and context. Use the new hook to identify thread-parent messages.
* **ChannelDetail:** outside a modal, the ChannelDetail views render no close
button unless ChannelDetail or ChannelDetailProvider gets onClose. They used to
render a close button that did nothing.
* **ChannelDetail:** ChannelDetail calls onLayoutChange on every layout change. It
used to ignore the prop.
* **AttachmentSelector:** SimpleAttachmentSelector, and the plain upload button AttachmentSelector renders when File is its only action, follow the composer's File rule instead of the upload-file capability alone. They appear without upload-file when attachments.customCdn is set, are hidden when attachments are disabled (the channel type's uploads flag is off without customCdn, or the client sets attachments.enabled: false), and are disabled once the message holds maxNumberOfFilesPerMessage files. At that limit the menu's File item also stays, disabled, where v14 hid it. See BC-065 in ai-docs/v15-breaking-changes.md and "Attachment and poll availability" in ai-docs/ai-migration-v14-v15.md.
* deprecated message, mention and list APIs are removed.
- `renderText(text, mentionedUsers, options)` is now `renderText(text, options)`, and `RenderTextFunction` is `(text, options)`. Pass mentions as `options.messageMentionEntities`, built with `getRenderTextMentionEntities(message)`.
- Custom mention renderers get `node.mentionedEntity` instead of `node.mentionedUser`.
- `onMentionsClick` / `onMentionsHover` are called with `(event, message)`; the `mentioned_users` argument and the `MentionedUserEventHandler` type are removed (use `CustomMentionHandler`). Read the clicked mention from the target's `data-user-id` / `data-mention-id`.
- `MessageContextValue.onMentionsClickMessage` / `onMentionsHoverMessage` and the handlers from `useMentionsHandler` are `undefined` unless `onMentionsClick` / `onMentionsHover` is passed. Mentions are interactive only when a click handler is set.
- `mentionsMarkdownPlugin` and `createMentionPluginAndDisplayTextSet` take mention entities only, not `UserResponse[]`.
- `useUserRole` is renamed `useMessagePermissions(message)`, and it no longer returns `isAdmin`, `isModerator` or `isOwner`; gate on the `can*` flags or `useChannelCapabilities()`.
- `disableQuotedMessages` is removed from `MessageList`, `Message` and `useMessagePermissions`. To hide quoting, pass a `messageActionSet` without the `quote` item through the `MessageActions` slot.
- `VirtualizedMessageList` drops `defaultItemHeight`, `overscan` and `scrollSeekPlaceHolder`; pass them through `additionalVirtuosoProps`.
- `PinEnabledUserRoles` and `PinPermissions` are removed; use `useMessagePermissions(message).canPin`.
See ai-docs/v15-breaking-changes.md (BC-087 to BC-095) and ai-docs/ai-migration-v14-v15.md.
* message context and grouping API changes.
- MessageProps.threadList and MessageContextValue.threadList are removed. Detect a thread
with `!!useThreadContext()`.
- ReactionSelector.getDialogId takes only `{ messageId }`; the reaction selector dialog id
no longer has a `-thread` part. Each message list has its own dialog manager.
- MessageContextValue.endOfGroup, firstOfGroup and groupedByUser are removed. Read
`useMessageContext().groupStyles[0]` (`top`, `middle`, `bottom` or `single`).
- The str-chat__virtual-message__wrapper--end, --first and --group classes are no longer
applied. Target the list item's .str-chat__li--top / --middle / --bottom / --single.
- MessageList.noGroupByUser and VirtualizedMessageList.shouldGroupByUser are replaced by
groupByUser (defaults: true and false). VirtuosoContext.shouldGroupByUser is groupByUser.
- The groupStyles function prop of both lists is renamed getGroupStyles and is called with
one GetGroupStylesParams object: { groupByUser, maxTimeBetweenGroupedMessages, message,
nextMessage, previousMessage }. The exported getGroupStyles takes the same object, and
useEnrichedMessages takes getGroupStyles and groupByUser instead of groupStyles and
noGroupByUser.
See BC-048, BC-085 and BC-086 in ai-docs/v15-breaking-changes.md.
* **MessageComposer:** useUserRole(message).canEdit is now the update permission alone
(update-any-message, or update-own-message on the user's own message). It no
longer excludes poll messages and giphies. A custom UI that gated an edit button
on it and wants that rule adds `!message.poll_id && message.command !== 'giphy'`.
* **MessageComposer:** the edit, copyMessageText and download rules about the message
moved from useBaseMessageActionSetFilter onto the items of
defaultMessageActionSet as isVisible. A hand-written edit, copyMessageText or
download item without isVisible now shows wherever the base filter allows it,
e.g. edit on a poll message the user may update. Copy the default item's
isVisible to keep the rule. Item isVisible rules also apply when
disableBaseMessageActionSetFilter is set, which previously returned the set
unfiltered, and to failed messages: a poll message or giphy that failed to send
for a network reason no longer offers Edit.
* **MessageComposer:** a message with a poll renders its text and attachments too, and
the quoted message now renders above the poll instead of below it. Such a
message gets str-chat__message--has-poll and no longer gets
str-chat__message--has-single-attachment.
* **MessageComposer:** custom AttachmentPreviewList, VoiceRecordingPreviewSlot and
LinkPreviewList components mount only while their item in
defaultMessageComposerPreviewSet is visible: attachments while the composer holds
an attachment other than a voice recording, voiceRecording while it holds a voice
recording, linkPreviews while a link preview is loading or loaded. Previously they
mounted whenever the preview area showed. A custom component that also renders
something else (a location, a poll, an empty or upload state) replaces its item
with one whose isVisible covers it.
* channel.watch() resolves with the channel instance to use (the channel, or the instance that superseded it), not the server response: read channel.data, channel.state and channel.messagePaginator instead.
- channel.watch() sends no query for a channel already watched and loaded unless it asks for options the current watch was not sent with, so it no longer refreshes one: refresh with channel.reload(), load other messages through channel.messagePaginator.
- A channel.watch() while another with the same options is in flight joins it instead of sending a request.
* **MessageList:** useMessageListScrollManager no longer takes onScrollToTop. Loading older messages keeps the message the reader was looking at in place, also when loading starts at the very top, instead of pinning the newly loaded page to the top.
- InfiniteScrollPaginator's loadNextDebounceMs now rate-limits the edge check while scrolling (the first check runs at once, then at most once per loadNextDebounceMs) instead of waiting until scrolling stops for that long. Older and newer pages start loading before the reader reaches the edge.
- MessageList and VirtualizedMessageList pass showNotification to NewMessageNotification only when a message from someone else arrives while the list is scrolled up. Being on an older message set no longer shows it; ScrollToLatestMessageButton signals that.
- In a channel, ScrollToLatestMessageButton shows the current user's unread count from the channel's read state instead of counting message.new events, so messages a reconnect brought in are included. In a thread it counts new replies from 0.
* marker: the removals are v14 API, so the branch has a
`fix!:` commit with a `BREAKING CHANGE:` footer, per the AGENTS.md
convention. The footer to keep in the squash commit:
* `MessageList` no longer accepts `messages`, `hasMore`,
`jumpToLatestMessage`, `loadingMoreNewer` or `messageLimit`, and
`VirtualizedMessageList` no longer accepts `messages`; the lists render
and paginate the message paginator. `CustomClasses.chatContainer` and
the `ComponentContext.LoadingErrorIndicator` slot are removed. Inside
`ChatView` the channel list no longer renders its own `str-chat <theme>`
scope. See ai-docs/v15-breaking-changes.md (BC-019, BC-046, BC-047,
BC-073, BC-074).
Verification: `yarn lint`, `tsc -p tsconfig.lib.json --noEmit`, `yarn
types:scripts`, `yarn validate-translations` and `yarn test` (281 files,
3090 tests) pass. `yarn build`, `validate-cjs`, `validate-esm`,
`validate-entry-isolation`, and the tutorial and vite example builds
passed before the rebase onto the guides branch, which brought in only
docs and the api-surface script. The ai-chatbot example build was not
verified: it hung locally in a sandboxed environment. The theme-scope
change was not checked visually in a browser.
### UI Changes
No intended visual change inside `ChatView`. Outside `ChatView`, the
channel list picks up the design tokens again, as in v14. The
`MessageList` loading indicator now appears while older messages load.
No screenshots: the examples need Stream credentials to run.

<!-- end of auto-generated comment: release notes by coderabbit.ai -->
* the `options` prop of `useCreateChatClient` is renamed to
`config`, and its type changes from `StreamChatOptions` to the `stream-chat`
configuration tree (`DeepPartial<InstanceConfigTree>`). Options that were
passed at the top level now go under the `client` key, for example
`options={{ baseURL, axiosRequestConfig }}` becomes
`config={{ client: { baseURL, axiosRequestConfig } }}`. Requires a
* requires stream-chat 10.0.0-rc.20 or later; client.activeChannels, client.getChannelById() and client.getChannelByMembers() are gone, use client.channelManager.get(cid), values() and client.channel() / client.channelManager.ensure({ type, id, data }); the thread list is client.threads.paginator, and threads come from client.threads.ensure() / get().
* getChannel() is removed; get the channel from client.channelManager.ensure() and call channel.ensureWatched(options).
* channel search results, and the channels message search fetches for its results, are no longer watched; a custom search result component watches the channel when it is opened (channel.ensureWatched(), or jumpToMessage(id, { watchChannel: true }) for a message).
* port the tutorial alignment (#3251) to v15, with panel-aware workspace navigation (#3301)
* **MessageComposer:** the `preventClearingOnUnmount` prop is removed from
`MessageComposer`. Drop it. If you relied on unmounting to clear a
composer supplied through `MessageComposerControllerProvider`, call
`clear()` on it yourself when your UI is done with it.
* `ChannelListItemProps.channelUpdateCount` is removed.
The unread badge now updates without it.
* `ChannelListItemProps.key` is removed. React's own
`key` prop is unaffected.
* `ChannelListItemProps.watchers` is removed. It had no
effect in v15.
* adopt stream-chat's branded TimestampNS (#3297)
* **Attachment:** `useSendMessageFn` and `useUpdateMessageFn` are removed. Call
`messageComposer.send()` and `messageComposer.update()` instead. They resolve
`'sent' | 'nothing-to-send' | 'failed'` rather than a boolean, so a truthiness
check on the result now passes for every outcome — compare against `'sent'`.
* **Attachment:** the two message submission failure notifications changed key.
`messageComposer.sendMessageFn.sendMessageRequestFailed.text` is now
`notification.messageSendFailed`, and
`messageComposer.updateMessageFn.editMessageRequestFailed.text` is now
`notification.messageUpdateFailed`. A typed custom translation dictionary fails
to compile until both are renamed.
* **Attachment:** `RetryHandler` takes `Omit<OperationParams<'retry'>, 'message'>`
instead of `RetrySendMessageWithLocalUpdateParams`, which stream-chat removed in
GetStream/stream-chat-js#1882. Code that names the old type must be updated.
* the `stream-chat` peer range moves to `^10.0.0-rc.12`. That release removes
`connection.changed`, changes `client.wsConnection` from the socket itself to a wrapper, and moves
the socket's settings into configuration. See GetStream/stream-chat-js PR 1859 for the full list;
an application on an earlier `stream-chat` will not typecheck against this version.
* connectivity is read from state stores rather than events. Code that listened for
`connection.changed` — to render its own banner, to refetch on reconnect — must subscribe to
`client.wsConnection.state` or `client.networkConnection.state` instead, or use the new
`useWSConnectionState` / `useNetworkConnectionState` hooks. Nothing in this package dispatches or
forwards the old event. Note the two stores name their fields differently: the socket's `isHealthy`
is always a boolean, while the network's `isOnline` is `boolean | undefined`, where `undefined`
means no platform reporter has reported yet and must be tested with `=== false`.
* `Channel` no longer reloads its channel on `connection.recovered`. The client
reloads every active channel itself and dispatches the event afterwards, so handling it here
reloaded each open channel twice per reconnect. Anything relying on the component to refresh a
channel after a reconnect should rely on the client instead.
* a socket drop on a working network now renders "Reconnecting…" rather than
"Waiting for network…", from the new `chat.reportLostConnection.reconnecting.text` key. Tests and
dictionaries keyed on the old copy for that case need updating; the `waitingNetwork` key is
unchanged and still used when the device network is down. The delay before either banner appears
now comes from `client.wsConnection.config.offlineNotificationDisplayDelayMs` (5s default) rather
than from a fixed hold inside the client, so changing that config changes when the banner shows.
The `system:network:connection:lost` notification type is unchanged.
* `Thread` requires a `thread` prop and renders `children`.
`additionalMessageComposerProps`, `additionalMessageListProps`,
`additionalParentMessageProps`, `additionalVirtualizedMessageListProps`, `autoFocus` and
`virtualized` are removed — pass those props to the children you render. `Thread`
provides the thread itself, so it no longer needs to be wrapped in `ThreadProvider`. The
`str-chat__thread--virtualized` class is gone; `Thread` cannot know which list you chose.
* `Thread.enableDateSeparator` is removed with nothing in its place. A
`MessageList` in a thread now follows its own default and shows date separators unless
you pass `withDateSeparator={false}`.
* `disableDateSeparator` is renamed to `withDateSeparator` on
`MessageList` (default `true`, was `disableDateSeparator={false}`) and
`VirtualizedMessageList` (default `false`, was `disableDateSeparator={true}`). The rename
also reaches `processMessages`, `useEnrichedMessages`, `FloatingDateSeparator`,
`useFloatingDateSeparator` and `useFloatingDateSeparatorMessageList`.
* the `head` prop is removed from `MessageList` and
`VirtualizedMessageList`. Both render the thread's parent message from context; override
it with a `ThreadHead` component on `ComponentContext`.
* `ThreadHeaderProps` is down to `overrideTitle`. `thread` comes from the
thread in context, and `closeThread` goes through workspace navigation — customize it
centrally via `ChatView`'s `deriveWorkspaceNavigation`, or call the new `useCloseThread()`
hook from a header of your own. `ComponentContext.ThreadHeader` is removed; compose the
header you want.
* `ThreadSlot` wraps its children in `<Thread>` instead of letting them
replace the whole panel, mirroring `ChannelSlot`. Markup that must sit outside the thread
container moves outside `ThreadSlot`; anything needing thread context must sit inside.
* `Thread` no longer rebuilds its subtree when the thread changes. A
custom component rendered inside `Thread` that relied on being remounted per thread — to
reset local state, or to re-run a mount effect — must depend on the thread instead. The
SDK's own message list does this by keying on the thread; `WithAudioPlayback` by taking
`playbackScope`.
* `LegacyThreadContext` and its `legacyThread` value are removed. The
thread composer resolves its composition context from the `Thread` instance in
`ThreadContext`.
* **MessageActions:** the `messageActions` prop is removed from `Channel`,
`MessageList`, `VirtualizedMessageList`, `Thread` and `Message`. Filter
`defaultMessageActionSet` and pass the result as `messageActionSet`
instead.
* **MessageActions:** `MESSAGE_ACTIONS`, `OPTIONAL_MESSAGE_ACTIONS`,
`getMessageActions()`, and the `MessageActionsArray` and `Capabilities`
types are no longer exported. Use the new `DefaultMessageActionType`
union for the action types the SDK ships.
* **MessageActions:** `MessageContext` no longer carries `getMessageActions`
or `actionsEnabled`. The rendered action set is decided by
`messageActionSet` and each item's own `isVisible` predicate.

* **AudioPlayback:** `ChannelProps.allowConcurrentAudioPlayback`,
`ThreadProps.allowConcurrentAudioPlayback` and
`WithAudioPlaybackProps.allowConcurrentPlayback`
are removed, with no replacement. If you passed `true`, delete it:
starting a player now pauses
whichever was playing and takes the shared element over. If you passed
`false` or nothing, the
only change is that playback is exclusive across surfaces rather than
within one.
* **AudioPlayback:** `useActiveAudioPlayer()` now reports the app-wide
active player rather than the
calling surface's.
* **Channel:** `ChannelProps.channel` is now required and
`EmptyPlaceholder` is removed.
Render the exported `ChannelPlaceholder` to fill the same
`.str-chat__channel` layout slot
while no channel is selected.
* **Channel:** `Channel` no longer queries the channel;
`initializeOnMount` and
`channelQueryOptions` are removed. Whoever supplies the channel
initializes it — use the
exported `getChannel({ channel, client })`, which watches and
de-duplicates concurrent calls.
Channels from `ChannelList` or any `queryChannels` call arrive watched
already. `Channel` no
longer renders `LoadingIndicator` or `LoadingErrorIndicator` for a query
it does not make, and
an uninitialized channel renders as an empty channel with no error.
* **Channel:** `Channel` no longer writes `document.title`, and
`activeUnreadHandler` is
removed. See `examples/vite/src/DocumentTitleManager` for a working
replacement in application
code.
* **Channel:** the `channel.channelMissing.text` translation key is
removed. This is a
compile error (TS2353) for any dictionary typed with the exact
`TranslationDictionary` —
delete the entry from custom locale files.
* **Channel:** `ChatContext.latestMessageDatesByChannels` is removed.
Slow-mode cooldown now
lives on `channel.cooldownTimer` (`useCooldownRemaining` /
`useIsCooldownActive`), and the
channel's latest message on
`channel.messagePaginator.aggregateState.lastMessage`.
* **Channel:** `Channel` no longer jumps to a message focused from
search. Selecting a search
result calls `channel.messagePaginator.jumpToMessage(id)` directly, and
the highlight is read
from `channel.messagePaginator.messageFocusSignal`. A custom message
list that relied on
`Channel` performing the jump must call `jumpToMessage` itself.
* **i18n:** consume the shared runtime from @stream-io/i18n (#3284)
* move to timestamps in response models (#3278)
* request-handler props are removed from `Channel` and
`Thread`.
`doSendMessageRequest`, `doUpdateMessageRequest`,
`doDeleteMessageRequest` and
`doMarkReadRequest` are gone, along with `useChannelRequestHandlers`,
`useThreadRequestHandlers` and `useEditMessageHandler`. Register once on
the client:
```
// v14
<Channel channel={channel} doSendMessageRequest={mySend}>
// v15
client.config.set({
channel: {
requestHandlers: {
sendMessageRequest: async ({ localMessage, message, options }) => ({
message: await mySend(message, options),
}),
},
},
});
```
Three differences: handlers take a single params object and return `{
message }`; thread
flows register under the `thread` key; and registration is per CLIENT,
not per mounted
subtree — the one thing the props could do that this cannot. Per-channel
behaviour now
needs a branch inside one handler on the `cid` it receives.
* `useChannelConfig` returns the channel's RESOLVED
configuration instead
of the channel type's raw server config, so field names change:
channelConfig?.typing_events → channelConfig?.typingEvents.enabled
channelConfig?.read_events → channelConfig?.readEvents.enabled
channelConfig?.replies → channelConfig?.replies.enabled
channelConfig?.user_message_reminders →
channelConfig?.userMessageReminders.enabled
channelConfig?.commands → channelConfig?.availableCommands
Every gate is now the server flag ANDed with what is registered through
`client.config`,
which is what the client actually enforces. The hook also subscribes:
these were getters,
so a `client.config.set()` previously never reached the screen. No
component reads
`channel.serverConfig` any more.
* `useAttachmentManagerState` replaces
`hasCustomDoUploadRequest` with
`customCdn`, and gains `attachmentsEnabled`, `locationEnabled` and
`pollsEnabled`.
* the per-domain stores on `channel.state` are removed —
`readStore`,
`typingStore`, `membersStore`, `watcherStore`, `ownCapabilitiesStore`,
`mutedUsersStore`.
Subscribe to `channel.state` itself; the selector is unchanged, because
`ChannelStateData`
is flat and keeps the same top-level keys:
useStateStore(channel.state.ownCapabilitiesStore, sel) →
useStateStore(channel.state, sel)
`WatcherState` is renamed `ChannelWatchState`, and
`channel.disconnected` is renamed
`channel.pendingDisposal` (removed outright — no deprecated alias).
* `AIStates` is no longer exported from
`stream-chat-react` — import it
from `stream-chat`. The values are unchanged, but it is now
literal-typed, so an inferred
array of its members no longer accepts the wide `AIState`:
const STOPPABLE: readonly AIState[] = [AIStates.Thinking,
AIStates.Generating];
* `<Channel>` marks its channel active while mounted and
reloads it on
`connection.recovered`. The client skips re-seeding an active channel's
message list on
hydration and reconnect, so the consumer owns that window. A custom
channel surface that
does not render `<Channel>` must call `channel.activate()` /
`deactivate()` and
`channel.reload()` itself, or its list goes stale after a reconnect.
* **i18n:** adopt the shared i18n layer from stream-chat/i18n (#3271)
* **context:** - **Context hooks no longer accept a `componentName` argument.**
`useChatContext('X')` and friends stop type-checking; drop the argument.
- **Required contexts throw when used outside their provider**, instead
of logging a warning and returning `{}`. Affects the 14 hooks listed
above. Components must be rendered within the provider they read from —
e.g. anything calling `useChatContext` needs a `<Chat>` ancestor.
- **`useChannelInstanceContext` returns
`Partial<ChannelInstanceContextValue>`** — `channel` is now typed as
possibly `undefined`.
- **`ChatViewContext` has no default value** (typed `| undefined`), so
`useContext(ChatViewContext)` may return `undefined`.
- **`MessageComposerContext` is typed as `MessageComposerContextValue |
undefined`**, correcting a narrower declaration that was papered over
with casts.
- **The gallery header no longer uses the
`ComponentContext.MessageTimestamp` override**; it renders the item's
own timestamp.
### 🛠 Implementation details
Parameter removed from all 7 hooks and their 138 call sites.
Missing-provider behaviour also normalized, since `src/` had three
competing conventions (warn + `{} as T`, throw, silent cast). The `{} as
T` fallback deferred failures to a downstream `Cannot read properties of
undefined` several frames away. Everything now goes through
`requireContext` (`src/context/requireContext.ts`):
- **Required → throw**, naming hook and provider: `useChatContext`,
`useMessageContext`, `useMessageComposerContext`,
`useMessageListContext`, `useVirtualizedMessageListContext`,
`useMessageBounceContext`, `usePollContext`, `useDialogManager`,
`useSearchContext`, `useSearchSourceResultsContext`,
`useContextMenuContext`, `useChannelListItemContext`,
`useGalleryContext`, `useChatViewContext`
- **Optional by design → keep default, honest type**:
`useTranslationContext`, `useComponentContext`,
`useChannelInstanceContext` (now `Partial`), `useModalContext`,
`useAriaLiveAnnouncer`, `useMessageTranslationViewContext`
- **Renders both inside and outside a provider → read the raw context**:
`Audio`, `VoiceRecording`, `CardAudio`, `Timestamp`,
`MessageRepliesCountButton`, `MessageComposerUI`, `ModalGallery`
Two changes were needed before their hooks could throw:
- `WithDragAndDropUpload` detected the composer via
`Object.keys(ctx).length > 0`; now uses a
`useIsWithinMessageComposerContext()` predicate. Adds the test file this
component lacked.
- `GalleryHeader` read message context while rendering outside any
`MessageProvider`. `GalleryItem` now carries `user` and `createdAt` —
wrapping the call sites would be wrong, since `ChannelMediaView`
flattens many messages into one list. Adds a
`timestamp.GalleryTimestamp` key.
`ChatViewContext` also loses its module-level `LayoutController`
default, which let unrelated subtrees write to one shared instance.
`src/context/__tests__/missingProviderContract.test.tsx` pins the
required/optional split.
### 🎨 UI Changes
The channel-media gallery header now shows a per-item sender and
timestamp, which it previously couldn't display at all.
No screenshots: the demo users on the shared environment have no
channels, and seeding one would write test data others would see.
Covered by unit tests in `GalleryUI.test.tsx` — worth a manual look.
* the <Chat> prop and the ChatContext field channelPaginatorsOrchestrator are renamed to channelManager, and the types ChannelPaginatorsOrchestrator / ChannelPaginatorsOrchestratorState are now ChannelManager / ChannelManagerState. Every useChatContext() consumer reading the old field, and any test that builds a partial ChatContext value, has to be updated. No deprecated prop or type aliases are exported.
* requires stream-chat v10.
* Removed `ChannelStateContext` and `ChannelActionContext` along with
`useChannelStateContext()`, `useChannelActionContext()`,
`useCreateChannelStateContext()` and `useCreateChannelActionContext()`.
Read the channel via `useChannel()` and message state via
`useMessagePaginator()`; both are backed by LLC `StateStore`s.
* `ChatContext` no longer exposes the active channel or `setActiveChannel()`.
Channel/thread routing is slot-driven — use `useChatViewNavigation()` from
`stream-chat-react/slot-layout` (`openChannel`, `openThread`, `closeThread`).
* The `TypingContext` provider path was removed from the `Channel` runtime.
`TypingIndicator` now derives its state from LLC stores and takes
`isMessageListScrolledToBottom` and `scrollToBottom` props.
* Context mutation/pagination helpers were replaced by paginator methods:
`updateMessage`/`removeMessage` -> `ingestItem`/`removeItem`;
`loadMore`/`loadMoreNewer` -> `toTail()`/`toHead()`;
`jumpToMessage`/`jumpToFirstUnreadMessage` -> `messagePaginator.jumpToMessage()`/
`jumpToTheFirstUnreadMessage()`. Messages are no longer in `channel.state`.
* Custom send/update/delete/markRead overrides move from ChannelActionContext
callbacks to `channel.configState.requestHandlers` /
`thread.configState.requestHandlers`.
* `ChatView` is a navigation landmark, not a WAI-ARIA Tabs widget: the selector
is `role="navigation"` with `aria-current` on the active button. There is no
`role="tab"`/`"tablist"`/`"tabpanel"`. `activeChatView` renamed to `activeView`.
* `ChannelList` renders a `role="listbox"` whose items are `role="option"`.
* v10 data shapes: channel name/image read from `channel.data.custom.name`/
`.custom.image`; user custom fields from `user.custom` (e.g. `username`);
attachment `duration`/`file_size`/`mime_type`/`waveform_data` from
`attachment.custom`. Message moderation uses `message.moderation`
(`moderation_details` is gone).

Ticket: https://linear.app/stream/issue/REACT-1441/make-messagecomposerpreviews-composable-like-the-message-action-set
Closes REACT-1430
Depends on GetStream/stream-chat-js#1970 (the vite example removes stream-chat's poll-only middleware, which that PR exports). It is released in 10.0.0-rc.29, which this PR now depends on.
🎯 Goal
Let integrators choose, order and extend what the message composer shows above the input, the same way they already can with the message action set. Let an app attach a poll to the message being composed, let a message bubble show a poll next to its text and attachments, and let each message action decide for itself which messages it applies to.
🛠 Implementation details
Composer previews
MessageComposerPreviewsrendersdefaultMessageComposerPreviewSet: edited message, quoted message, voice recording, attachments, link previews, location. Each item is{ type, Component, isVisible(params) }, whereparamsisMessageComposerPreviewVisibilityFilterParams. The area renders only when an item is visible.messageComposerPreviewSetprop, or theMessageComposerPreviewsslot inWithComponents.useMessageComposerPreviewState()anduseMessageComposerPreviewSetFilter()are exported for custom containers.EditedMessagePreviewandGeolocationPrevieware now exported from the root.MessageComposerPreviewVisibilityFilterParamsincludepollId, so a custom item can show the poll the composer holds.Poll in the composer: no SDK preview
examples/vite/src/ComposerPreviews/PollPreview.tsx): question, option count with the first options, and the poll's settings. Remove detaches the poll without deleting it, because the composer cannot tell whether it created the poll or whether it was already sent (e.g. apoll_idrestored from a draft). A poll that no longer exists is detached, so the send does not fail on it. The preview is hidden while editing.Poll creation dialog
PollCreationDialogControlsslot, so an app can replace "Send poll" with, for example, an "Attach poll" button.Message bubble
MessageBubbleContentrendersdefaultMessageBubbleContentSet(quoted message, poll, attachments, text), customizable through a prop or theMessageBubbleContentslot. Items getMessageBubbleContentVisibilityFilterParams.str-chat__message--has-pollclass.MessageContext, so updates the memoizedMessageUIskips (e.g. the translation toggle) still reach it. Props passed toMessageUIoverride the context for the whole message.Message actions
isVisible(params), withMessageActionVisibilityFilterParams({ isMyMessage, isThreadReply, message }). It holds the action's own rule about the message, and replacing the item changes it.useBaseMessageActionSetFilteronto their items:edithides for a poll message (poll_id) or a giphy,copyMessageTextfor a message without text,downloadfor one without a downloadable attachment.isVisiblecan only hide an action. Capabilities, features enabled on the server and the message's status stay in the base filter and cannot be overridden.useUserRole().canEditis now the update permission alone, the same check the base filter makes.Example app (vite)
Known limitations
poll_id, andclient.pollsis not reactive. A poll preview therefore has to fetch an uncached poll itself and keep it in its own state; the example does this as a stopgap. Fixing it needs a reactive poll store in stream-chat: REACT-1494, out of scope for v15.0.Docs
ai-docs/ai-migration-v14-v15.mdcovers the preview set, the poll dialog footer slot with an "Attach poll" example and an app-side poll preview item, the message bubble content set, and the action items'isVisiblerules.isVisible,canEdit).Tests: previews (order, edit mode, custom and removed items, slot, no default poll preview, a custom item showing the composer's poll, axe), the translation toggle reaching the bubble text, bubble content (order, classes, custom set, axe), the dialog footer slot, action visibility rules (poll edit hidden by default, also for a failed local poll message, and allowed by a replaced item, params passed to
isVisible, no override of capabilities, rules applied with the base filter off), andcanEditfor a poll message.💥 Breaking changes
