Fix more WaveAI scroll issues #1597
Conversation
WalkthroughThe pull request introduces significant modifications to the The primary changes involve restructuring how chat messages are handled within the The Components like These changes represent a fundamental shift towards a more modular and reactive state management strategy, leveraging Jotai's capabilities to handle complex state interactions more efficiently within the application's chat functionality. 🪧 TipsChatThere are 3 ways to chat with CodeRabbit:
Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments. CodeRabbit Commands (Invoked using PR comments)

34-34: Consider a naming convention improvement.
Renaming “chatItemAtom” to “chatMessageAtom” (or similar) can enhance clarity.-interface ChatItemProps { - chatItemAtom: Atom<ChatMessageType>; +interface ChatItemProps { + chatMessageAtom: Atom<ChatMessageType>; model: WaveAiModel; }
514-515: Ref forwarding for ChatWindow.
Forwarding the ref is a neat solution to give parent components access to the underlying OverlayScrollbars instance.
524-559: Scrolling logic & user scroll detection.
The combination of throttle+debounce is practical, but watch out for event overlap and performance overhead if the chat grows. Consider testing under high message throughput.

16-16: LGTM on importing splitAtom.
No issues found with the import statement for Jotai’s splitAtom utility.
77-78: Addition of messagesSplitAtom and latestMessageAtom.
This approach effectively enables more granular re-renders. Good job using splitAtom for message splitting and an atom for the latest message.
99-100: Atom initialization looks good.
The logic for creating splitAtom and latestMessageAtom is consistent with Jotai patterns.
415-415: Ensuring only necessary data is exposed.
Returning just “sendMessage” from useWaveAi is a clean approach, preventing unnecessary coupling with internal state.
438-439: Atom-based component design is solid.
Using a dedicated atom for each chat item can improve performance by limiting re-renders to only the affected chat.
517-519: Split messages & the latest message usage.
Leveraging multiple atoms is a good pattern; verify concurrency if multiple updates occur simultaneously.
680-680: Destructuring sendMessage from the model.
This is straightforward and keeps the WaveAi component clean.
744-744: Handle potential stale closures.
Ensure that additional dependencies (e.g., “model”) don’t change while the effect depends solely on “value.” If so, update the dependency array to avoid stale references.
851-851: ChatWindow usage.
Integrating the ChatWindow with forwardRef seamlessly is solid. No immediate issues found here.
This adds a split atom for the messages so that the WaveAI component and the ChatWindow component don't actually need to watch changes to all of the messages. This makes the repaining a lot less expensive and makes it easier to scroll while new messages come in.
I also increased the tolerance on the
determineUnsetScrollcallback so that the bottom message won't get unattached as easily.
