Review Change Stack

📝 Walkthrough

Walkthrough

Adds categorized preset SVG avatars, a validated PATCH endpoint for authenticated updates, and an AvatarPickerModal integrated into ProfileHeaderCard for selecting, uploading, saving, or removing avatars.

Changes

Preset Avatar Picker

Layer / File(s) Summary
Preset avatar data contract and helpers
lib/presetAvatars.ts
Defines PresetAvatar, encodes SVG markup as data:image/svg+xml URLs, and exports categorized preset avatars.
Backend avatar update endpoint
app/api/profile/avatar/route.ts
Adds authenticated PATCH handling. The handler validates the preset source, updates user.image, and returns success or 400/401 responses.
Avatar picker modal and profile header integration
app/profile/ProfileHeaderCard.tsx
Adds modal selection, upload triggering, CSRF-protected preset updates and removal, loading feedback, toast handling, and NextAuth session updates.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 570a6

Preset avatar updates can leave visitors seeing an outdated profile image, and malformed avatar requests can produce server errors instead of clear client errors. These localized correctness issues should be fixed or explicitly accepted before merging.

AvatarPickerModal's open prop (the modal's "open" state) and resets

selection always reflects the real current avatar.

Hi @Diyapareta,

Thanks for the PR, Could you please address the CodeRabbit review comment above regarding the "selectedAvatar" state not re-syncing with "currentAvatar"? Since the modal remains mounted, the current implementation may lead to stale selection states when reopening the picker or after avatar updates.

Please make the necessary changes, resolve the review comment, and mark it as resolved once completed.

Thanks!

- Around line 292-296: The effect in ProfileHeaderCard that calls
setSelectedAvatar(currentAvatar) inside useEffect causes the
react-hooks/set-state-in-effect lint error; remove that state update and instead
either (A) force a remount of the picker/modal subtree by giving the inner
picker/dialog content a key derived from currentAvatar (keep the outer Dialog
component mounted so close animation still runs) or (B) stop syncing state and
derive the shown avatar value directly during render from currentAvatar when
open is true; locate the useEffect, setSelectedAvatar, currentAvatar, open and
Dialog/picker components and implement one of these fixes so no state is set
inside the effect.

Thanks for PR!
Pls resolve this issues:

  • [route.ts]: Accept a preset id (e.g. "fox") instead of the full [src](; lookup the canonical [src] server-side and update DB. Adds robustness and avoids comparing long data-URIs.

  • [ProfileHeaderCard.tsx]: Send the preset id on save (not the [src]), and use the project absolute import ([@/lib/presetAvatars]) for consistency.

  • [presetAvatars.ts]: Export a PresetAvatar type and keep the array typed as PresetAvatar[]; consider serving presets as static assets for caching instead of large data-URIs.

  • Add unit tests for the new [PATCH /api/profile/avatar] endpoint (happy path, invalid id, unauthenticated).

Return a client error for invalid JSON.

await req.json() throws for malformed JSON, and destructuring a JSON null body also throws. The handler currently returns an unhandled 500 response for these client errors. Parse the body inside try/catch, then validate an unknown body before reading avatar.

Invalidate the public-profile cache after preset updates.

PATCH updates user.image but does not call invalidateProfileCache. ProfileHeaderCard.tsx updates the local session, but cached public profiles can still show the previous avatar. Call await invalidateProfileCache(session.user.id) after the database update, as POST and DELETE already do.
