Walkthrough

The changes update the visual representation of file attachments in several components by switching from FileIcon to FileTextIcon for non-image files and adjusting related layout styles. Additionally, internal logic for handling attachments, message updates, and attachment loading is improved for greater robustness and consistency, particularly around asynchronous data fetching and thread state management.

Changes

File(s)	Change Summary
.../chat-list/attachment-cards.tsx, .../prompt-form/attachments-display.tsx, .../prompt-form/user-attachments.tsx	Updated imports to include FileTextIcon. Changed the icon for non-image attachments from FileIcon to FileTextIcon. Adjusted icon sizes and layout styles for attachment display. Added conditional debug logging for attachment content in dev mode.
.../lib/helpers/ai-helpers.ts	Enhanced convertToCoreMessages to fetch and embed remote attachment data as base64 data URIs when necessary, improving how remote attachments are handled in messages.
.../lib/hooks/use-chat-attachments.ts	Refined attachment fetching logic to wait for thread loading state to be 'finished' before retrieving attachments from IndexedDB, preventing premature or redundant fetches.
.../lib/hooks/use-mb-chat.tsx	Refactored message saving and thread update logic after AI message generation. Improved state update ordering, error handling, and navigation logic for more consistent thread and UI state management.

A hop and a skip, new icons appear,
FileText now shines, the intent is clear.
Attachments fetched with a careful paw,
Threads updated without a flaw.
In the warren of code, all is bright—
Rabbits rejoice, the UI feels right! 🐇✨

Hey @AndlerRL - I've reviewed your changes - here's some feedback:

• In convertToCoreMessages the fetchUrl call isn’t awaited, so attachmentContent may be used before the download completes—please await the fetch/arrayBuffer and update attachmentContent synchronously before returning.
• Using Buffer.from on the client can break in browser environments—consider using browser-native APIs (e.g. btoa/atob or a small ArrayBuffer→base64 helper) or polyfilling Buffer.
• You removed the throttle wrapper around updateActiveThread in MBChatProvider—make sure rapid consecutive calls won’t lead to race conditions or duplicate state updates.

455-463: Potential issue with error handling in uploadNewMessages.

The catch block for uploadNewMessages doesn't assign the result to newThreadMessages when retrying, which could lead to newThreadMessages being an empty array when the thread update logic runs.

Apply this fix to ensure proper error recovery:

 try {
   newThreadMessages = await uploadNewMessages()
 } catch (error) {
   console.error('Error generating message slugs: ', error)
   
   // ? If the error is due to duplicate key value, we retry the upload one more time to do the recursive check again
   // ! This might be an edge case now that we use drizzle for this query, but it is still a good practice to handle this error
   if ((error as Error).message.includes('duplicate key value')) {
-    await uploadNewMessages()
+    newThreadMessages = await uploadNewMessages()
   }
 }

Learning: In `apps/masterbots.ai/lib/hooks/use-chat-attachments.ts`, the `validateTextContent` function intentionally uses `slugify()` with character removal (`remove: /[^\w\s]/g`) followed by splitting on hyphens to count words. This approach is preferred over simple whitespace splitting because it removes special characters (like those found in code text) and counts only "true words", making it more robust for validating pasted content that may contain mixed text and code.

Learning: In `apps/masterbots.ai/lib/helpers/ai-helpers.ts` the `verifyDuplicateMessage` function should:
• Use `message.content` as the sole de-duplication key so provisional (no-slug) and persisted (slugged) messages merge properly.
• Return the full `message` object (not just a string key) for the continuation prompts (`CONTINUE_GENERATION_PROMPT`, `CONTINUE_GENERATION_PROMPT_2`) because their content repeats and they must remain distinct.
• No explicit `!message.content` guard is needed; `return message.content` already yields `undefined` when content is missing.

Learning: In `apps/masterbots.ai/lib/hooks/use-chat-attachments.ts`, the `validateTextContent` function intentionally uses `slugify()` with character removal (`remove: /[^\w\s]/g`) followed by splitting on hyphens to count words. This approach is preferred over simple whitespace splitting because it removes special characters (like those found in code text) and counts only "true words", making it more robust for validating pasted content that may contain mixed text and code.

Learning: In `apps/masterbots.ai/lib/helpers/ai-helpers.ts` the `verifyDuplicateMessage` function should:
• Use `message.content` as the sole de-duplication key so provisional (no-slug) and persisted (slugged) messages merge properly.
• Return the full `message` object (not just a string key) for the continuation prompts (`CONTINUE_GENERATION_PROMPT`, `CONTINUE_GENERATION_PROMPT_2`) because their content repeats and they must remain distinct.
• No explicit `!message.content` guard is needed; `return message.content` already yields `undefined` when content is missing.

apps/masterbots.ai/components/routes/chat/prompt-form/user-attachments.tsx (1)

9-9: LGTM! Improved semantic icon usage.

The change from FileIcon to FileTextIcon for non-image attachments provides better visual semantics and aligns with the consistency improvements across attachment components.

Also applies to: 48-48

apps/masterbots.ai/components/routes/chat/prompt-form/attachments-display.tsx (1)

11-11: LGTM! Consistent icon improvement.

The switch to FileTextIcon maintains consistency with the other attachment display components and provides clearer visual semantics for text file attachments.

Also applies to: 82-82

apps/masterbots.ai/components/routes/chat/chat-list/attachment-cards.tsx (2)

23-28: Verify the dramatic icon size increase.

The change from FileIcon to FileTextIcon is consistent with other components, but the size change from size-5 (20px) to size-24 (96px) is significant. Please verify this large icon size aligns with the design requirements.

Also applies to: 82-82

---

93-94: Layout adjustments look appropriate.

The width calculations and max-width reduction appear to be accommodating the layout changes, likely reserving space for the attachment dialog trigger (32px) and adjusting text truncation accordingly.

apps/masterbots.ai/lib/hooks/use-chat-attachments.ts (2)

64-64: Good addition of loading state tracking.

Adding loadingState from the thread context enables better control over when attachments are fetched.

---

80-85: Improved attachment fetching logic.

The additional condition to prevent fetching attachments until loadingState is 'finished' prevents unnecessary IndexedDB queries during thread loading and improves performance consistency.

apps/masterbots.ai/lib/helpers/ai-helpers.ts (1)

180-180: Update to use processed attachment content is correct.

The usage of attachmentContent instead of the original content is the right approach, but this will only work correctly once the async fetching logic is fixed.

Also applies to: 191-193

apps/masterbots.ai/lib/hooks/use-mb-chat.tsx (6)

445-448: Good type safety improvement.

The explicit return type assertion makes the function signature clearer and enables better type checking for the consuming code.

---

451-454: Proper variable assignment for downstream usage.

This change correctly captures the result of uploadNewMessages for use in subsequent thread update logic, which is essential for the refactored code flow.

---

478-495: Well-structured thread update logic.

The explicit thread object creation with proper merging of messages and attachments is much clearer than the previous implementation. The use of uniqBy for deduplication is appropriate.

---

497-517: Improved navigation control flow.

Moving the navigation inside the try block and making it conditional ensures it only executes after successful thread updates, which is the correct behavior.

---

519-521: Better state management ordering.

Moving these state updates to after thread updates and navigation ensures the loading states are only cleared after the operation completes successfully.

---

591-596: Improved error handling cleanup order.

The reordering ensures proper cleanup sequence in the error handler, maintaining consistency with the successful flow.
