refactor: call Channel.watch(), which replaces ensureWatched() in stream-chat - #3346
Merged

Conversation
…eam-chat stream-chat renames ensureWatched() to watch(): it sends nothing for a channel already watched and loaded and resolves with the instance to use. The channel and user search results and the channel detail's "send direct message" action call it. A message search result loads its channel with the jump alone (jumpToMessage with watchChannel), one request instead of a watch followed by the jump. Refs REACT-1341.

watch() itself sends nothing for a channel already watched and loaded, and initialized does not mean watched or loaded, so the tutorial, ai-chatbot and vite examples call it directly. The vite deep link loads its channel with the jump alone (jumpToMessage with watchChannel). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Migration and API guidance AGENTS.md, ai-docs/ai-migration-v14-v15.md, ai-docs/instance-configuration.md, ai-docs/v15-breaking-changes.md |
Guidance and examples use client.channel() and watch() in place of channelManager.ensure() and ensureWatched(). The guides describe returned channel instances and watch behavior. |

Application and example setup uses client.channel() with the existing channel data. The affected stream-chat dependencies were updated to rc.25. |

Channel restoration and sending flows call watch(). Message-result selection passes watchChannel: true to jumpToMessage(). Search and direct-message tests cover watch resolution and channel-instance handling. |
Test channel access migration src/components/**/__tests__/*, src/plugins/**/__tests__/*, src/mock-builders/utils.ts |
Test setup and mock builders use client.channel() to obtain channels. The scroll-to-latest test calls reload() instead of watch(). |

## [15.0.0-rc.3](v15.0.0-rc.2...v15.0.0-rc.3) (2026-10-28) ### ⚠ BREAKING CHANGES * channel.watch() resolves with the channel instance to use (the channel, or the instance that superseded it), not the server response: read channel.data, channel.state and channel.messagePaginator instead.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. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Gallery items can display message-specific timestamp overrides. * Reply-count buttons honor a message’s custom thread-opening behavior. * Standalone channel lists now inherit the chat theme, and channel-detail actions use workspace navigation. * `useMessagePaginator` and `useIsCooldownActive` are available from the package entry point. * Message timestamps can render with an explicit message outside a message context. * **Bug Fixes** * Message-list loading indicators and pagination behavior now reflect active page loads more accurately. * Workspace navigation warns when navigation actions are used without a provider. * **Breaking Changes** * Removed legacy message-list props and the `LoadingErrorIndicator` component override slot. <!-- end of auto-generated comment: release notes by coderabbit.ai --> ### Bug Fixes * correct issues found during the comment cleanup ([#3334](#3334)) ([7f87026](7f87026)) * **examples:** translate the voice visualization keys in the vite example ([#3352](#3352)) ([c88ab33](c88ab33)), closes [#3347](#3347) * **MediaRecorder:** stop the recording timer when the preview unmounts ([#3351](#3351)) ([3c8b30a](3c8b30a)) * **MessageList:** keep the reader's place on older pages and count only arrived messages as new ([#3342](#3342)) ([ab00d67](ab00d67)) * remove dead v15 surface and restore v14 behaviors found by the API audit ([#3328](#3328)) ([d721f40](d721f40)), closes [#3327](#3327) [#3305](#3305) [#3237](#3237) ### Features * **ai-components:** add useHeardText for voice-paced text ([#3348](#3348)) ([ec7c956](ec7c956)), closes [#3343](#3343) [#3344](#3344) [#3344](#3344) [#3343](#3343) [#3339](#3339) [#3347](#3347) * **ai-components:** add VoiceWave and VoiceGlow voice-agent visualizations ([#3347](#3347)) ([216d00d](216d00d)), closes [#3339](#3339) [#3339](#3339) [#3339](#3339) ### Refactors * call Channel.watch(), which replaces ensureWatched() in stream-chat ([#3346](#3346)) ([0100d98](0100d98))

🎯 Goal
Follow GetStream/stream-chat-js#1943 (REACT-1341):
Channel.ensureWatched()is renamed toChannel.watch(). The newwatch()sends nothing for a channel already watched and loaded unless it asks for options the current watch was not sent with, joins a watch in flight with the same options, and resolves with the instance to use.Requires
stream-chat@10.0.0-rc.25, the first release with GetStream/stream-chat-js#1943. The dev dependency, the three examples and the peer range (^10.0.0-rc.25) are bumped: with rc.24,watch()resolves with the server response.🛠 Implementation details
SDK
ChannelSearchResultItem,UserSearchResultItemand the channel detail's "send direct message" action callwatch()instead ofensureWatched(); the DM flows still use the instancewatch()resolves with.MessageSearchResultItemloads its channel with the jump alone:jumpToMessage(item.id, { watchChannel: true })loads the page around the message and the channel state, and watches, in one request. It used to callwatch()first for a channel that was never loaded, which sent a newest-page query before the jump's own query.Examples
useSendAIMessage) and the vite example callawait channel.watch()without anif (!channel.initialized)guard.watch()itself sends nothing for a channel already watched and loaded, andinitializeddoesn't mean watched or loaded: a channel from a list queried withwatch: false, or afterquery()/create(), isinitializedwithout being watched or without messages.?focus=<cid>:<messageId>deep link loads its channel with the jump alone, like the message search result.Docs
AGENTS.md,ai-docs/ai-migration-v14-v15.md,ai-docs/instance-configuration.mdandai-docs/v15-breaking-changes.mddescribe the singlewatch(), and point tochannel.reload()for refreshing a watched channel.CHANGELOG.mdis generated and left as is.client.channel()instead ofchannelManager.ensure()ChannelManager.ensure()as@internal;client.channel()is the public way to get a channel and calls it, with the same behaviour.examples/vite/docs-playwright),AGENTS.mdand the AI docs callclient.channel().client.channel()as the public way to get a channel, calling the internalchannelManager.ensure().Tests
SearchResultItem: the "already watched" test marks the channel watched and loaded and checks that no query is sent; the message result test expects the jump alone, with{ watchChannel: true }.ScrollToLatestMessageButton: the tests that simulate a reconnect re-query throughchannel.reload(), sincewatch()on a watched channel now sends nothing.stream-chat@10.0.0-rc.25, after mergingmaster:yarn types,yarn lintandyarn test(3294) pass; the vite, tutorial and ai-chatbot examples type-check.
