Walkthrough

Adds client-side directives to chat input and messages components; refactors ChatMessages typing, streaming extraction, and empty-state handling; tweaks stream-message padding; replaces ChatTab loading fallback with a centered spinner; removes a debug log and an ESLint suppression; and updates ChatConversation shape (title required, suggestions moved top-level) with corresponding DB mapper changes.

Changes

Cohort / File(s) Summary
Client component directives
apps/web/client/src/app/project/[id]/_components/right-panel/chat-tab/chat-input/index.tsx, apps/web/client/src/app/project/[id]/_components/right-panel/chat-tab/chat-messages/index.tsx
Added 'use client' to convert these modules to client components (enables hooks/window/clipboard/etc.).
ChatMessages refactor & rendering
apps/web/client/src/app/project/[id]/_components/right-panel/chat-tab/chat-messages/index.tsx, apps/web/client/src/app/project/[id]/_components/right-panel/chat-tab/chat-messages/stream-message.tsx
Reformatted component params, improved typing for useMemo result ({ messages, streamedMessage }), clarified streaming logic (extract last assistant message when streaming), reorganized empty-state vs messages rendering; adjusted stream-message wrapper padding from py-2 to pt-2.
ChatTab loading UI
apps/web/client/src/app/project/[id]/_components/right-panel/chat-tab/index.tsx
Replaced null loading fallback with a full-width, centered loading panel using Icons.LoadingSpinner and "Loading messages..." text; useQuery usage unchanged.
useChat cleanup
apps/web/client/src/app/project/[id]/_hooks/use-chat/index.tsx
Removed a debug console.log in editMessage and applied minor formatting; no behavioral changes.
Suggestions lint comment removal
apps/web/client/src/app/project/[id]/_components/right-panel/chat-tab/suggestions.tsx
Removed // eslint-disable-next-line react/display-name comment before the forwardRef wrapper (lint rule will now apply).
Right-panel whitespace
apps/web/client/src/app/project/[id]/_components/right-panel/index.tsx
Deleted an extra blank line; no functional change.
ChatConversation model & DB mapper changes
packages/models/src/chat/conversation/index.ts, packages/db/src/mappers/chat/conversation.ts
Public model changed: ChatConversation.title is now `title: string

Pre-merge checks and finishing touches

✅ Passed checks (3 passed)
Check name Status Explanation
Title Check ✅ Passed The title "feat: more chat cleanup" is directly related to the changeset because the PR focuses on chat-related refactors and cleanup across components and models, so it correctly signals the primary intent; however the phrasing is somewhat generic and could be made more specific to surface the most important changes (e.g., client conversion of components and conversation model updates).
Description Check ✅ Passed The PR description includes the repository template but leaves its sections blank while also providing a detailed autogenerated Ellipsis summary that documents the refactors, client conversions, streaming fixes, style tweaks, and removed debug logs, so reviewers have useful context; however several template fields remain unfilled. Key template items that are missing or incomplete are the "Type of Change" checkboxes, explicit "Testing" steps, and any linked "Related Issues," which are helpful for risk assessment and verification. Given the presence of a clear functional summary I consider the description mostly complete but needing those template fields filled before merge.
Docstring Coverage ✅ Passed No functions found in the changes. Docstring coverage check skipped.

🧹 Nitpick comments (4)
apps/web/client/src/app/project/[id]/_components/right-panel/chat-tab/chat-input/index.tsx (3)

155-158: Use internationalization for placeholder text.

The ASK mode placeholder text is hardcoded as "Ask a question about your project..." but should use the internationalization system like the EDIT mode does.

Apply this diff to use internationalization consistently:

 const getPlaceholderText = () => {
     if (chatMode === ChatType.ASK) {
-        return 'Ask a question about your project...';
+        return t(transKeys.editor.panels.edit.tabs.chat.input.placeholderAsk);
     }
     return t(transKeys.editor.panels.edit.tabs.chat.input.placeholder);
 };

You'll need to add the corresponding translation key to your i18n configuration.


267-267: Use internationalization for toast message.

The screenshot success toast message "Screenshot added to chat" should use internationalization.

-            toast.success('Screenshot added to chat');
+            toast.success(t(transKeys.editor.panels.edit.tabs.chat.screenshotAdded));

418-418: Use internationalization for tooltip content.

The "Stop response" tooltip text should use internationalization.

-            <TooltipContent>{'Stop response'}</TooltipContent>
+            <TooltipContent>{t(transKeys.editor.panels.edit.tabs.chat.stopResponse)}</TooltipContent>
apps/web/client/src/app/project/[id]/_components/right-panel/chat-tab/chat-messages/index.tsx (1)

91-91: Consider simplifying the contentKey logic.

The contentKey computation is complex and could be simplified for better maintainability.

Consider extracting this logic to a helper function or simplifying it:

+const getContentKey = (messages: ChatMessage[], isStreaming: boolean): string => {
+    const messageIds = messages.map(m => m.id).join('|');
+    if (!isStreaming) return messageIds;
+    const lastMessageId = messages[messages.length - 1]?.id ?? '';
+    return `${messageIds}|${lastMessageId}`;
+};

 return (
     <ChatMessageList
-        contentKey={`${messages.map((m) => m.id).join('|')}${isStreaming ? `|${messages?.[messages.length - 1]?.id ?? ''}` : ''}`}
+        contentKey={getContentKey(messages, isStreaming)}

apps/web/client/src/app/project/[id]/_components/right-panel/chat-tab/chat-messages/stream-message.tsx (1)

12-12: Spacing change looks good.

The switch from py-2 (vertical padding) to pt-2 (top padding only) is appropriate for the stream message layout, preventing excessive spacing between the message content and the loading indicator below.

apps/web/client/src/app/project/[id]/_hooks/use-chat/index.tsx (1)

229-238: Clean return statement formatting.

The multi-line object literal formatting improves readability and is consistent with React hook conventions.

apps/web/client/src/app/project/[id]/_components/right-panel/chat-tab/chat-input/index.tsx (1)

1-1: Correct use of client directive.

Adding 'use client' is appropriate here as the component uses React hooks, event handlers, drag-and-drop, clipboard operations, and other browser APIs that require client-side rendering.

apps/web/client/src/app/project/[id]/_components/right-panel/chat-tab/index.tsx (1)

10-13: Good defensive programming with default value.

Using destructuring with a default empty array prevents potential runtime errors if the query returns undefined, ensuring ChatTabContent always receives a valid array.

apps/web/client/src/app/project/[id]/_components/right-panel/chat-tab/chat-messages/index.tsx (3)

1-2: Appropriate client component conversion.

Adding 'use client' is correct since this component uses hooks like useMemo, useCallback, and the MobX observer HOC, all requiring client-side rendering.


33-47: Well-structured streaming logic with proper typing.

The refactored streaming logic is cleaner and more type-safe. The explicit type annotation for the memoized result improves code clarity and prevents type inference issues.


76-87: Good empty state handling.

The empty state now correctly shows only when there are no messages AND no elements selected, preventing confusing UI states.

packages/db/src/mappers/chat/conversation.ts (1)

12-18: Critical: don’t spread ChatConversation into DbConversation — omit chat-only fields and use nullish coalescing

Spreading the source leaks Chat-only fields (e.g., title) into the DB shape and the current || coalescing collapses valid falsy values; remove title/suggestions from the spread and use ??.

File: packages/db/src/mappers/chat/conversation.ts (both fromDbConversation and toDbConversation)

Suggested change for toDbConversation (apply the symmetric pattern to fromDbConversation — destructure/omit displayName before returning and use ??):

 export const toDbConversation = (conversation: ChatConversation): DbConversation => {
-    return {
-        ...conversation,
-        projectId: conversation.projectId,
-        displayName: conversation.title || null,
-        suggestions: conversation.suggestions || [],
-    }
+    const { title, suggestions, ...rest } =
+      conversation as ChatConversation & Record<string, unknown>;
+    return {
+        ...(rest as Omit<DbConversation, 'displayName' | 'suggestions'>),
+        displayName: title ?? null,
+        suggestions: (suggestions as ChatConversation['suggestions']) ?? [],
+    } as DbConversation
 }

Strongly typed non‑optional is preferable and the DB mapper defaulting to [] complements this; repository search for metadata.suggestions and conversation.metadata returned no matches, so no cleanup required.

⚠️ Potential issue

Use ?? instead of || and avoid spreading DB rows into model objects.

  • || null will convert '' to null. Use ?? null to only default on null/undefined.
  • Spreading ...conversation (a Db row) risks leaking DB‑only fields into the model and can trigger excess‑property issues.

Suggested refactor:

 export const fromDbConversation = (conversation: DbConversation): ChatConversation => {
-    return {
-        ...conversation,
-        title: conversation.displayName || null,
-        suggestions: conversation.suggestions || [],
-    }
+    return {
+        id: conversation.id,
+        title: conversation.displayName ?? null,
+        projectId: conversation.projectId,
+        createdAt: conversation.createdAt,
+        updatedAt: conversation.updatedAt,
+        suggestions: conversation.suggestions ?? [],
+    }
 }

In packages/db/src/mappers/chat/conversation.ts around lines 7-8, the mapper
currently uses `||` which will coerce empty strings and falsy values incorrectly
and also may be spreading the DB row into the model; change
`conversation.displayName || null` to `conversation.displayName ?? null` and
`conversation.suggestions || []` to `conversation.suggestions ?? []`, and remove
any object spread of the raw DB row—explicitly construct the model by listing
only the allowed fields (e.g., id, title, suggestions, createdAt, updatedAt) so
DB-only columns are not leaked into the returned model.

export interface ChatConversation {
id: string;
title?: string;
title: string | null;

⚠️ Potential issue

🧩 Analysis chain

Required title now allows null — verify call sites and prefer nullish coalescing.

Good change for explicitness. Ensure all producers/consumers set null (not undefined) and update any code that used optional title. Downstream, prefer ?? checks to avoid treating empty strings as falsy unintentionally.

Run a quick sweep for legacy optional access and falsy checks:


🏁 Script executed:

#!/bin/bash
# Legacy optional title usage

# Falsy title checks that may collapse '' to null/false

Use nullish coalescing for conversation.title and ensure producers emit null

  • packages/db/src/mappers/chat/conversation.ts:16 — replace
    displayName: conversation.title || null
    with
    displayName: conversation.title ?? null
  • apps/web/client/src/app/project/[id]/_components/right-panel/chat-tab/history.tsx:91 already uses conversation.title ?? 'New Conversation' (no change).
  • Search for producer sites that set/assign title (object literals / .title =) and ensure they emit null (not undefined) when no title exists.

In packages/models/src/chat/conversation/index.ts around line 5, the
conversation.title field is typed as string | null; update call sites
(specifically packages/db/src/mappers/chat/conversation.ts around line 16) to
use nullish coalescing (conversation.title ?? null) instead of logical OR so
falsy non-null titles like empty string are preserved, and audit producer sites
that construct or assign conversation.title (object literals and .title =
assignments) to ensure they explicitly emit null (not undefined) when no title
exists; change any places returning undefined to return null and adjust any
factory/defaults to set title: null when appropriate.
