Walkthrough

Migrates chat persistence from Drizzle to Supabase (server/browser clients, RPCs, migrations, RLS), rewires API routes and UI to new chat types/flows, adds realtime subscriptions, sharing/invitations via chat participants, and RAG-based prompt augmentation with optional geospatial rendering. Removes legacy DB modules/config. Adds Playwright verification scripts.

Changes

Cohort / File(s) Summary
Supabase clients & persistence
lib/supabase/client.ts, lib/supabase/browser-client.ts, lib/supabase/persistence.ts
Adds server/browser Supabase clients and a persistence layer (save chat/messages, retrieve messages, system prompt CRUD, save drawings, create message).
Database migrations & RLS
supabase/migrations/0000_init.sql, supabase/migrations/0001_realtime_collaboration.sql
Creates core schema (chats, messages, system_prompts, locations, visualizations), search functions, RPC, triggers; adds chat_participants, shareable_link_id, and RLS policies for collaboration.
Remove Drizzle-based stack
lib/db/index.ts, lib/db/schema.ts, lib/actions/chat-db.ts, drizzle.config.ts
Deletes Drizzle ORM client, schema, chat DB actions, and config.
Chat actions (Supabase migration)
lib/actions/chat.ts
Reimplements chat APIs with Supabase (getChats, getChat, getChatMessages, clearChats, saveChat, updateDrawingContext, system prompt functions).
RAG retrieval & prompt augmentation
lib/actions/rag.ts, app/actions.tsx
Adds retrieveContext(...) and uses augmented system prompt; renders GeoJsonLayer for user messages and resolution search results with geoJson.
API routes (chat CRUD/list/clear)
app/api/chat/route.ts, app/api/chats/route.ts, app/api/chats/all/route.ts
Switches to Supabase-based saveChat; simplifies list to getChats(userId); clear history via clearChats. Adds auth checks and streamlined responses.
Chat UI & realtime
components/chat.tsx, components/chat-panel.tsx
Fetches chat on mount, passes chatId/shareableLink to children, subscribes to Supabase realtime for messages/presence; updates props and types.
Settings & collaboration invite
components/settings/settings-view.tsx, components/settings/components/settings.tsx, components/settings/components/user-management-form.tsx, lib/actions/collaboration.ts
Threads chatId through Settings; changes roles to owner/collaborator; replaces add user with inviteUserToChat(chatId,email) and associated server checks/inserts.
History UI updates
components/history-item.tsx, components/history-list.tsx, components/sidebar/chat-history-client.tsx
Standardizes on shared Chat type; updates loaders/endpoints; sets explicit paths; refines error handling.
Search page data loading
app/search/[id]/page.tsx
Uses getChat(id) without userId; loads messages via getChatMessages and passes as AIMessage[].
Verification scripts
jules-scratch/verification/verify_chat_creation.py, .../verify_share_button.py
Adds Playwright scripts to validate chat creation flow and share dialog behavior.
Remove legacy users actions
lib/actions/users.ts
Deletes in-memory user management APIs/types.

Hop-hop! I wired the chats, supa-fast and bright,
Realtime whiskers twitching in the night.
Maps now shimmer where the queries roam,
Context crumbs lead bun-bots home.
Invite a friend—collab delight!
New carrots saved, with prompts just right. 🥕✨

PR Compliance Guide 🔍

Below is a summary of compliance checks for this PR:

Security Compliance
Supabase auth config

Description: The server client uses the public anon key from NEXT_PUBLIC_SUPABASE_ANON_KEY for
server-side operations, which may lack required privileges and can cause RLS bypass
attempts or misconfigurations; a service-role key should not be exposed client-side, and
server actions should ensure proper auth context rather than relying on anon environment
vars.
client.ts [8-26]

Referred Code
  process.env.NEXT_PUBLIC_SUPABASE_URL!,
  process.env.NEXT_PUBLIC_SUPABASE_ANON_KEY!,
  {
    cookies: {
      async get(name: string) {
        const store = await cookieStore
        return store.get(name)?.value
      },
      async set(name: string, value: string, options: CookieOptions) {
        const store = await cookieStore
        store.set({ name, value, ...options })
      },
      async remove(name: string, options: CookieOptions) {
        const store = await cookieStore
        store.set({ name, value: '', ...options })
      },
    },
  }
)
Unintended redirect

Description: clearChats calls redirect('/') after deletion which may be invoked via API or server
action leading to unexpected open redirect-like behavior or denial-of-service in clients;
consider returning status and letting caller navigate to avoid forcing redirects from
server actions.
chat.ts [85-87]

Referred Code
  revalidatePath('/')
  redirect('/')
}
Weak embedding stub

Description: The generate_embedding function returns a zero vector placeholder which can degrade search
quality and potentially leak system assumptions; while not a classic vuln, deploying with
placeholder embedding undermines RAG effectiveness and may mislead access controls tied to
search results.
0000_init.sql [86-101]

Referred Code
-- PL/pgSQL function to generate embeddings
CREATE OR REPLACE FUNCTION generate_embedding(input TEXT)
RETURNS VECTOR(1536)
LANGUAGE plpgsql

    -- to the embedding endpoint. For now, we'll return a zero vector.
    SELECT ARRAY_FILL(0, ARRAY[1536])::VECTOR INTO embedding;
    RETURN embedding;
END;
$$;
Prompt injection risk

Description: retrieveContext results are interpolated directly into the system prompt without
sanitization, which could enable prompt injection via stored message content; consider
delimiting and attributing retrieved snippets and applying content filtering.
actions.tsx [285-291]

Referred Code
const userId = 'anonymous'
const currentSystemPrompt = (await getSystemPrompt(userId)) || ''

const retrievedContext = await retrieveContext(userInput, aiState.get().chatId)

Complete core feature implementations

The PR's key features, real-time collaboration and RAG, are incomplete as they
rely on non-functional placeholders. The presence tracking uses a hardcoded user
ID and the embedding generation returns a zero vector, rendering these features
useless.

Examples:

components/chat.tsx [105]
          await channel.track({ user_id: 'user-placeholder', online_at: new Date().toISOString() });
supabase/migrations/0000_init.sql [87-100]

    -- This is a placeholder for the actual Supabase embedding function call.
    -- In a real Supabase project, you would use the http extension or a direct call

Solution Walkthrough:

Before:

// In components/chat.tsx
...
channel.subscribe(async (status) => {
  if (status === 'SUBSCRIBED') {
    // Presence tracking uses a hardcoded placeholder
    await channel.track({ user_id: 'user-placeholder', ... });
  }
});
...

// In supabase/migrations/0000_init.sql
CREATE OR REPLACE FUNCTION generate_embedding(input TEXT) ...
AS $$
BEGIN
  -- RAG embedding is a non-functional stub returning a zero vector
  SELECT ARRAY_FILL(0, ARRAY[1536])::VECTOR INTO embedding;
  RETURN embedding;
END;
$$;

After:

// In components/chat.tsx
...
const { data: { user } } = await supabase.auth.getUser();
channel.subscribe(async (status) => {
  if (status === 'SUBSCRIBED' && user) {
    // Presence tracking should use the actual user's ID
    await channel.track({ user_id: user.id, ... });
  }
});
...

// In supabase/migrations/0000_init.sql
CREATE OR REPLACE FUNCTION generate_embedding(input TEXT) ...
AS $$
BEGIN
  -- RAG embedding should call a real embedding service
  -- (Example using pg_net to call an external service)
  RETURN supabase_functions.http_request(...);
END;
$$;

Why: The suggestion correctly identifies that two core advertised features, RAG and real-time collaboration, are implemented with non-functional placeholders, making them inoperable and representing a critical implementation gap.

High
Possible issue
Provide user ID to fetch chat
Suggestion Impact:The commit changed the getChat call to no longer pass an empty string; it now calls getChat(id) instead of getChat(id, ''), aligning with the intent to fix the incorrect empty userId argument.

code diff:

-            const chat = await getChat(id, '');
+            const chat = await getChat(id);

Pass the authenticated user's ID to getChat instead of an empty string to
correctly fetch chat data.

components/chat.tsx [41-49]

 useEffect(() => {
   async function fetchChatData() {
       if (id) {
-          const chat = await getChat(id, '');
+          // Note: You'll need a way to get the current user's ID on the client.
+          // This is a placeholder for your actual auth implementation.
+          const { data: { user } } = await getSupabaseBrowserClient().auth.getUser();
+          const userId = user?.id || '';
+          const chat = await getChat(id, userId);
           setChatData(chat);
       }
   }
   fetchChatData();
 }, [id]);

Why: The suggestion correctly identifies a bug where getChat is called with an empty userId, which would cause it to always fail, and provides a correct fix using the Supabase client-side auth helper.

High
Use actual user ID for presence

Replace the hardcoded 'user-placeholder' with the actual authenticated user's ID
when tracking presence in a chat channel.

components/chat.tsx [103-107]

 .subscribe(async (status) => {
   if (status === 'SUBSCRIBED') {

+    // This is a placeholder for your actual auth implementation.
+    const { data: { user } } = await getSupabaseBrowserClient().auth.getUser();

+      await channel.track({ user_id: user.id, online_at: new Date().toISOString() });
+    }
   }
 });

Suggestion importance[1-10]: 9

__

Why: The suggestion correctly identifies a critical bug where a hardcoded user_id breaks the real-time presence feature, and the proposed fix correctly uses the Supabase client to get the actual user ID.

High
Use authenticated user ID in settings

Replace the hardcoded 'anonymous' user ID with the actual authenticated user's
ID to ensure system prompts are saved and retrieved on a per-user basis.

components/settings/components/settings.tsx [67]

-// TODO: Replace 'anonymous' with actual user ID from session/auth context
-const userId = 'anonymous';
+// TODO: Replace with actual user ID from session/auth context
+// This is a placeholder for your actual auth implementation.

+    const { data: { user } } = await getSupabaseBrowserClient().auth.getUser();
+    setUserId(user?.id || null);
+  };
+  fetchUser();
+}, []);
+

[To ensure code accuracy, apply this suggestion manually]

Suggestion importance[1-10]: 9

__

Why: The suggestion correctly points out a critical bug where a hardcoded userId would cause all users to share the same system prompt, and the proposed fix correctly fetches the authenticated user's ID.

High
General
Check if user is already invited

Before inserting a new user into chat_participants, check if they are already a
participant to avoid attempting a redundant insertion and relying on database
error handling.

lib/actions/collaboration.ts [37-40]

+// Check if user is already a participant
+const { data: existingParticipant, error: participantError } = await supabase
+  .from('chat_participants')
+  .select('id')
+  .eq('chat_id', chatId)
+  .eq('user_id', userData.id)
+  .single();
+
+if (existingParticipant) {
+  return { error: 'User is already in this chat.' };
+}
+
 // Add the user to the chat_participants table
 const { error: insertError } = await supabase
   .from('chat_participants')
-  .insert({ chat_id: chatId, user_id: userData.id, role: 'collaborator' })
+  .insert({ chat_id: chatId, user_id: userData.id, role: 'collaborator' });
 
+if (insertError) {
+  console.error('Error inviting user to chat:', insertError);
+  return { error: 'Failed to invite user to the chat.' };
+}
+
  • Apply / Chat
Suggestion importance[1-10]: 5

__

Why: The suggestion correctly notes that checking for an existing participant is cleaner than handling a database error, but the existing code already handles the primary failure case (unique constraint violation), making this a minor improvement.

  • Realtime subscription is mutating UI state with DB messages, corrupting the UI state shape; switch to updating AI state and map fields consistently.
  • The collaboration invite flow queries a non-existent public.users.email; use an RPC against auth.users or a profiles table.
  • clearChats redirects from within an API-used function, breaking JSON responses.
  • Migrations reference public.users and use gen_random_uuid() without enabling pgcrypto, which will fail in typical Supabase setups.
Additional notes (1)
  • Maintainability | components/chat-panel.tsx:14-26
    ChatPanel received new props (chatId, shareableLink) but they’re not used anywhere in the component. Leaving unused props around increases component surface area and confusion.
Summary of changes
  • Replaced Drizzle-based persistence with Supabase across API routes and actions.
  • Integrated RAG context retrieval into the system prompt flow and augmented researcher prompt.
  • Added realtime Supabase subscription and presence tracking in Chat component; passed chatId to settings and user management.
  • Removed ChatShareDialog and Drizzle-related files; added Supabase clients, persistence layer, and migrations for collaboration (chat_participants, RLS policies) and RAG helpers.
  • Updated settings schema to use roles owner and collaborator; connected UserManagementForm to inviteUserToChat server action.
  • Adjusted history components and routes to use new chat fetching/deletion APIs.

GeoJsonLayer is used in JSX but not imported anywhere in this file. This will throw at runtime (and likely at compile time). Please import the component or remove the render until it’s properly wired up.

Suggestion

Add a proper import for the layer component (adjust the path to your actual component), and guard against missing location.geojson:

import { GeoJsonLayer } from '@/components/map/geojson-layer'
...
{location?.geojson && (
  <GeoJsonLayer id={`${id}-geojson`} data={location.geojson} />
)}

revalidatePath('/')

Choose a reason for hiding this comment

The reason will be displayed to describe this comment to others. Learn more.

This handler calls clearChats, which unconditionally performs a redirect('/'). Redirecting from within a function used by an API route will short-circuit your JSON response and likely break the client-side fetch call. API handlers should return a response, not trigger navigation.

Suggestion

Refactor clearChats to not redirect by default. For example:

export async function clearChats(userId?: string | null, options: { redirectOnSuccess?: boolean } = {}) {
  ...
  if (options.redirectOnSuccess) {
    revalidatePath('/')
    redirect('/')
  }
}

Then update callers in API routes to omit redirectOnSuccess and keep JSON responses consistent; use redirectOnSuccess: true only from server actions that can redirect. Reply with "@CharlieHelps yes please" if you'd like me to add a commit with this refactor

getChat still returns early if userId is missing, even though the Supabase server client is session-aware and RLS can enforce access. This prevents server callers that don’t have the user id at hand from fetching chats, and it already breaks the caller in components/chat.tsx.

Suggestion

Remove the if (!userId) return null guard and rely on the Supabase server client’s session with RLS to authorize. The function signature can keep userId for explicit filtering, but should not require it:

export async function getChat(id: string, userId?: string): Promise<Chat | null> {
  const supabase = getSupabaseServerClient()
  const { data, error } = await supabase
    .from('chats')
    .select('*, chat_participants!inner(*)')
    .eq('id', id)
    .single()
  if (error) { ... }
  return data as Chat
}

getChats ignores the userId parameter and selects * from chats. While RLS will restrict rows, it’s clearer and more efficient to filter at the query (e.g., by membership in chat_participants) to minimize scanned rows and make intent explicit.

Suggestion

Join/filter by chat_participants to return only chats the user belongs to:

const supabase = getSupabaseServerClient();
const { data, error } = await supabase
  .from('chats')
  .select('id, title, created_at, visibility')
  .in('id', (
    await supabase.from('chat_participants').select('chat_id').eq('user_id', userId)
  ).data?.map((r) => r.chat_id) || []);

Or use a single RPC tailored for this list. Reply with "@CharlieHelps yes please" if you want me to implement the filtered query.

The Supabase realtime insert handler is pushing raw DB rows into messages via setMessages, but messages here is the UI state from useUIState (an array of { id, component }), not the AI message list. Appending DB rows to UI state will corrupt the UI state shape and cause rendering issues.

Suggestion

Use useAIState to append to the AI messages instead of useUIState, and map the DB row to your AIMessage shape:

const [aiState, setAIState] = useAIState()
...
.on('postgres_changes', { event: 'INSERT', schema: 'public', table: 'messages', filter: `chat_id=eq.${id}` }, (payload) => {
  const m: any = payload.new
  const next = { id: m.id, role: m.role, content: m.content, createdAt: new Date(m.created_at) }
  setAIState(prev => ({ ...prev, messages: prev.messages.some(mm => mm.id === next.id) ? prev.messages : [...prev.messages, next] }))
})

getChatMessages now returns any[] and downstream code casts DB rows to AIMessage without mapping. The DB uses snake_case (created_at) and joins (locations(*)), which won’t match AIMessage fields. This will create subtle runtime issues.

Suggestion

Map DB rows to the AIMessage shape explicitly:

const raw = await getChatMessages(chat.id)
const initialMessages: AIMessage[] = raw.map((m: any) => ({
  id: m.id,
  role: m.role,
  content: m.content,
  createdAt: m.created_at ? new Date(m.created_at) : undefined,
  locations: m.locations,

The role selector in the User Management form is no longer used—the inviteUserToChat action ignores the selected role and always inserts collaborator. This is confusing UX and dead state in the form.

Suggestion

Either remove the role selector from the form, or plumb the selected role through to the action:

const role = form.getValues('newUserRole') || 'collaborator'
const result = await inviteUserToChat(chatId, newUserEmail, role)

and update inviteUserToChat signature to accept role: 'owner' | 'collaborator' and insert it. Reply with "@CharlieHelps yes please" if you'd like me to add a commit with this change

Settings still uses a hard-coded userId = 'anonymous' when saving the system prompt, so everyone is writing to the same record. This will overwrite prompts across users.

Suggestion

Refactor the saveSystemPrompt action to obtain the current user server-side (via getCurrentUserIdOnServer) so the client doesn’t need to pass an id. For example:

// server action
export async function saveSystemPromptForCurrentUser(prompt: string) { 
  const userId = await getCurrentUserIdOnServer(); if (!userId) return { error: 'Not authenticated' }
  return supabaseSaveSystemPrompt(userId, prompt)
}

This API route will still succeed even if clearChats triggers a redirect (see related comment). Ensure the delete call returns a 200 JSON response to the client instead of a redirect payload.

The Playwright script targets a "Share" button and dialog, but this PR removes the redundant ChatShareDialog. This script is likely stale and will fail CI or local verification.

@charliecreates charliecreates bot removed the request for review from CharlieHelps October 12, 2025 15:50
This commit fixes a critical client-side exception that occurred in the production deployment. The error "getChat called without userId" was caused by the `getChat` server action being called from a client component (`Chat.tsx`) without a valid user session being passed, which returned `null` and crashed the application.

The fix involves two main changes:
1.  **Robust `getChat` Action:** The `getChat` function in `lib/actions/chat.ts` has been refactored to no longer accept a `userId` as a parameter. Instead, it now reliably fetches the authenticated user's ID directly from the server-side session context using `getCurrentUserIdOnServer`. This makes the action more secure and independent of the client's state.
2.  **Updated Component Calls:** All components that previously called `getChat(id, userId)`, such as `Chat.tsx` and the search page, have been updated to call the function with only the chat `id`, i.e., `getChat(id)`.

This change ensures that data fetching is secure and functional in both local development (with a mock user) and the production environment, resolving the deployment failure.

91-102: Fix real-time handler to append UI messages correctly.

useUIState stores entries shaped like { id, component }, but here we push the raw Supabase row (payload.new) straight into messages. That yields elements without component, so the first realtime insert corrupts the UI state and nothing renders for remote messages. Map the row into your AI state (via useAIState) and derive the UI entry the same way submit() does instead of splicing the raw payload into messages.


84-112: Stop resubscribing the channel on every UI update.

Including messages/setMessages in this effect’s dependency list tears the channel down and recreates it on every render, which drops realtime events and thrashes presence. Keep the dependency to id and rely on functional state updates inside the handlers to avoid stale closures.


98-106: Track the real user in presence updates.

Calling channel.track with the hard-coded 'user-placeholder' causes every session to share the same presence key, so your online-user list is wrong and tabs stomp each other. Fetch the authenticated user id (e.g. const session = await supabase.auth.getSession()) and pass that instead.

lib/actions/collaboration.ts (1)

27-35: Use an auth-aware lookup for invitee email.

Querying from('users') will fail in production—Supabase doesn’t expose a public.users table with emails, so this returns a 42P01/404 and invites always error out. Resolve the user id via a SECURITY DEFINER RPC against auth.users (or another RLS-safe view) before inserting into chat_participants.

components/settings/components/settings.tsx (1)

67-90: Hard-coded userId = 'anonymous' causes cross-user data leaks.

Persisting the system prompt under a fixed "anonymous" key means every user reads/writes the same record—whoever saves last overwrites everyone else, and prompts bleed between accounts. Please resolve by fetching the real user id server-side in the action (or at least threading the actual id into this component).

app/search/[id]/page.tsx (1)

37-44: Map Supabase rows to AIMessage before casting.

getChatMessages still returns raw Supabase rows (snake_case fields like created_at, joined payloads, etc.). Casting them to AIMessage[] without normalization leaves createdAt/locations undefined at runtime, breaking chronological ordering and geo rendering. Please restore an explicit mapper (id, role, content, createdAt, locations, …) before handing the data to <AI>.

jules-scratch/verification/verify_share_button.py (1)

17-27: Verification script targets removed Share dialog.

This flow now lives in Settings—the Share button/dialog got removed with ChatShareDialog, so the locator never resolves and the run hangs. Please update the verification to cover the new collaboration UI instead of the old dialog.

components/settings/components/user-management-form.tsx (1)

45-57: Role selection is ignored by inviteUserToChat.

We still surface an Owner/Collaborator selector, but inviteUserToChat(chatId, email) drops that value—every invite is stored as the default role. That’s misleading UX and wrong data when owners try to elevate someone. Please either remove the selector or plumb the chosen role through to the action + persistence.

Also applies to: 91-107

lib/actions/chat.ts (1)

95-96: Redirect from a shared action still breaks API callers

clearChats still unconditionally redirect('/'). When API routes (e.g. app/api/chats) call this helper, the redirect short-circuits the JSON response. Please make the redirect optional so API contexts can return normally.

⚠️ Potential issue | 🔴 Critical

🧩 Analysis chain

Potential scalability issue: Removed pagination.

The endpoint now returns all chats at once instead of supporting pagination. For users with many chats (hundreds or thousands), this could cause:

  1. Increased memory consumption on the server
  2. Slow response times
  3. Large payload sizes affecting client performance

Verify that this is intentional and that there are practical limits on the number of chats per user, or consider re-introducing pagination or implementing a reasonable limit.

Check if there are database-level or application-level limits on chat count:


🏁 Script executed:

#!/bin/bash
# Description: Check for chat limits in persistence layer and schema

# Search for limits in persistence functions

Missing user filter and pagination in getChats

  • In lib/actions/chat.ts getChats(): .from('chats').select('*') ignores the userId parameter, returning all chats for all users. Add .eq('user_id', userId) (and fix the shadowed userId binding).

but the underlying getChats implementation currently queries
`.from('chats').select('*')` which ignores the userId, may shadow the parameter,

(remove any shadowing) and add a filter `.eq('user_id', userId)` plus a
pagination/limit call such as `.range(start, end)` or `.limit(n)` (and

Normalize Supabase rows before returning Chat objects

getChats/getChat return the raw Supabase payload cast to Chat, but the payload is still snake_case (user_id, created_at, shareable_link_id, nested chat_participants, etc.). Anywhere that expects the camelCase Chat shape (e.g., this module’s own saveChat check on chat.userId) will now see undefined and break downstream logic. Please convert the rows to the Chat contract before returning them.

Also applies to: 58-60

🤖 Prompt for AI Agents
In lib/actions/chat.ts around line 36 (and similarly at 58-60), the function
currently returns raw Supabase rows cast to Chat but those rows are snake_case
(user_id, created_at, shareable_link_id, chat_participants, etc.); map each
returned row into the Chat contract by converting snake_case keys to camelCase
(user_id -> userId, created_at -> createdAt, shareable_link_id ->
shareableLinkId), transform nested chat_participants into chatParticipants with
their camelCase fields, and preserve/convert types (e.g., createdAt to
string/Date if your Chat type expects that); perform null/undefined checks and
return the mapped array (or single mapped object) instead of the raw payload so
downstream code like saveChat sees chat.userId and other camelCase properties.

Cookie handlers must be synchronous (do not return Promises).

createServerClient expects cookies.get/set/remove to return synchronously; giving it async handlers hands Supabase a Promise instead of the cookie string, so auth/session parsing breaks. Also, removal should actually delete (e.g., cookieStore.delete). Please drop the async/await, use cookieStore directly, and call delete/set synchronously.

Fix by removing async/await from get/set/remove, access cookieStore directly

cookieStore.get(name)?.value, set call cookieStore.set({ name, value, ...options

Adapt Supabase message rows to AIMessage before returning

Both getMessagesByChatId and createMessage hand back the raw Supabase rows but advertise AIMessage. Those rows contain created_at/location_id etc., so the caller will never see createdAt/locationId. Normalize (or at least document) before returning so the contract stays truthful.

Create chat_participants before referencing it in the RPC

save_chat_with_messages inserts into public.chat_participants, but this table is only introduced in migration 0001.

Reintroduce an INSERT policy for public.chats

After dropping the old “manage their own chats” policy you only recreated SELECT and UPDATE/DELETE rules. With RLS enabled, lack of an INSERT policy blocks any user session from creating chats, so save_chat_with_messages will always fail. Add an explicit FOR INSERT ... WITH CHECK (auth.uid() = user_id) (or equivalent) so owners can still create chats.

the chat owner (for example WITH CHECK (auth.uid() = user_id)) or an equivalent
condition that ensures the inserting user becomes/ is the owner, so
save_chat_with_messages can insert new chats successfully.

26-35: Querying public.users by email will fail; use auth.users via SECURITY DEFINER RPC.

Supabase user emails live in auth.users. Querying public.users by email will 404 at runtime. Create an RPC (SECURITY DEFINER) and call it here. Also consider plumbing the role from the form (defaults to collaborator).

Apply this change to the query section:

-  // Get the user ID of the person being invited
-  const { data: userData, error: userError } = await supabase
-    .from('users')
-    .select('id')
-    .eq('email', email)
-    .single()
+  // Lookup user id via SECURITY DEFINER RPC that reads from auth.users
+  const { data: userId, error: userError } = await supabase
+    .rpc('get_user_id_by_email', { p_email: email.toLowerCase().trim() })

And update the insert to use userId:

-  .insert({ chat_id: chatId, user_id: userData.id, role: 'collaborator' })
+  .insert({ chat_id: chatId, user_id: userId, role: 'collaborator' })

Optionally accept role from caller:

-export async function inviteUserToChat(chatId: string, email: string): Promise<{ error?: string }> {
+export async function inviteUserToChat(
+  chatId: string,
+  email: string,
+  role: 'owner' | 'collaborator' = 'collaborator'
+): Promise<{ error?: string }> {
...
-  .insert({ chat_id: chatId, user_id: userId, role: 'collaborator' })
+  .insert({ chat_id: chatId, user_id: userId, role })

Ensure the RPC exists with SECURITY DEFINER and proper grants (as suggested earlier). Based on learnings

components/history-item.tsx (1)

6-6: LGTM: Clean type migration.

The import change from DrizzleChat to Chat and the corresponding type update align with the broader migration from Drizzle to Supabase. The change is straightforward and maintains type safety.

Also applies to: 10-10

components/history-list.tsx (1)

5-5: LGTM: Improved type safety and error handling.

The changes include several improvements:

  1. Migration to the new Chat type for better consistency across the codebase
  2. Explicit path construction (/search/${chat.id}) is clearer and more maintainable
  3. Added try/catch error handling provides better user experience when chat loading fails

These changes align well with the broader Supabase migration.

Also applies to: 11-13, 42-42, 53-61

components/settings/components/settings.tsx (1)

36-36: Ensure no legacy role values remain in the database
Run a real query against your Supabase instance (e.g. via supabase db query or direct psql) to find any records in chat_participants (or other user tables) where role NOT IN ('owner','collaborator'). If any rows are returned, add a migration to update old values before deploying.

In app/actions.tsx around lines 288 to 292, guard the call to retrieveContext so
it is only invoked when userInput is non-empty: if userInput is falsy, set
retrievedContext to an empty array (or directly set augmentedSystemPrompt =
currentSystemPrompt) instead of calling retrieveContext; otherwise call
retrieveContext(userInput, aiState.get().chatId) and build augmentedSystemPrompt
as before. Ensure types reflect that retrievedContext may be an empty array and
avoid passing undefined into retrieveContext.

In app/api/chat/route.ts around lines 22 to 36, the new Chat object sets path:
'' which can create broken shareable links; after generating the chat id,
populate path with the proper search URL (for example using the generated id,
e.g. `/search/${id}`) or assign path after constructing the id (compute path =
`/search/${newChat.id}`) so the created chat always contains a valid shareable
URL.

⚠️ Potential issue | 🟠 Major

Consider reintroducing pagination for scalability.

Removing pagination means all chats for a user are loaded in a single request. For users with hundreds or thousands of chats, this could cause:

  • Slow API response times
  • High memory consumption on both server and client
  • Poor user experience with large datasets
  • Potential timeout errors

If the previous pagination was removed intentionally (e.g., because most users have few chats), consider adding it back with sensible defaults:

 export async function GET(request: NextRequest) {
   try {
     const userId = await getCurrentUserIdOnServer();
     if (!userId) {
       return NextResponse.json({ error: 'Unauthorized' }, { status: 401 });
     }
 
+    const { searchParams } = new URL(request.url);
+    const limit = Math.min(parseInt(searchParams.get('limit') || '50'), 100);
+    const offset = Math.max(parseInt(searchParams.get('offset') || '0'), 0);
+
-    const chats = await getChats(userId);
+    const chats = await getChats(userId, { limit, offset });
     return NextResponse.json({ chats });
   } catch (error) {
     console.error('Error fetching chats:', error);
     return NextResponse.json({ error: 'Internal Server Error fetching chats' }, { status: 500 });
   }
 }

Alternatively, if pagination is truly unnecessary, add a comment explaining the rationale.

⚠️ Potential issue | 🔴 Critical

FKs point at public.users, but Supabase auth lives in auth.users

Supabase projects provide auth.users; there is no managed public.users table to alter or reference. These foreign keys and RLS policies will fail unless you manage a shadow public.users table yourself. Update every FK and policy here to target auth.users(id) (and remove the ALTER TABLE public.users block) so the migration runs on a standard Supabase stack.

In supabase/migrations/0000_init.sql around lines 16–55, the migration creates
FKs and RLS policies that reference public.users (which doesn't exist in a
standard Supabase project); update every REFERENCES public.users(id) to
REFERENCES auth.users(id), ensure any user_id columns keep the same UUID type,
update the RLS policy expressions to continue comparing auth.uid() to the
user_id column (no change to the auth.uid() usage required), and remove any
ALTER TABLE public.users ... blocks or references to a shadow public.users table
so the migration will run against the built-in auth.users table instead.

save_chat_with_messages references chat_participants before it exists

This function inserts into public.chat_participants, but that table is created in migration 0001. Because SQL functions are validated at creation time, this migration will fail as soon as the function is defined. Either create chat_participants in this migration (before the function) or defer the function definition until after the table exists.

In supabase/migrations/0000_init.sql around lines 139 to 152, the function
save_chat_with_messages inserts into public.chat_participants before that table
exists (it’s created in migration 0001), causing validation to fail; fix by
either adding the CREATE TABLE public.chat_participants statement to this
migration before the function definition or remove/relocate the function
definition to a later migration (0001 or later) after chat_participants is
created, and ensure any dependent indexes/constraints are present before
creating the function so SQL validation succeeds.
