⚡ Bolt: Optimize project lists fetching by deriving in-memory#193aicoder2009 wants to merge 1 commit into
Conversation
- Removes redundant fetch to `/api/projects/[id]/lists`. - Derives the project's lists using an in-memory array `.filter()` against the global `allLists` result. - Avoids duplicate database scans when both all lists and project lists are required simultaneously.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Handle /api/lists failure explicitly.
On Line 82, a failed /api/lists response leaves lists/allLists untouched and still clears isLoading, so the page can render stale data or a false “no lists yet” state for a project whose lists never loaded.
Suggested fix
- if (allListsResult.success) {
- setAllLists(allListsResult.data);
- // OPTIMIZATION: Derive project-specific lists in-memory from allLists
- // instead of making a duplicate backend database query.
- setLists(allListsResult.data.filter((list: List) => list.projectId === projectId));
- }
+ if (!allListsResult.success) {
+ setAllLists([]);
+ setLists([]);
+ setError(allListsResult.error || "Failed to load project lists");
+ return;
+ }
+
+ setAllLists(allListsResult.data);
+ // OPTIMIZATION: Derive project-specific lists in-memory from allLists
+ // instead of making a duplicate backend database query.
+ setLists(allListsResult.data.filter((list: List) => list.projectId === projectId));📝 Committable suggestion

💡 What
Removes a redundant backend API call (
/api/projects/[id]/lists) and derives the subset of lists associated with the givenprojectIdin-memory using an array filter against the global lists collection.🎯 Why
When a user views a project detail page, the application needs both the project details and the lists associated with that project. However, the UI also needs all available user lists to populate the "Add Existing List" dropdown. Previously, this meant making simultaneous calls for all lists and the project lists. Because DynamoDB currently lacks a GSI for
projectId, the backend endpoint for project lists fetches all lists and filters them anyway.By fetching only all lists and deriving the subset on the frontend, we remove a redundant network request and a duplicate database scan entirely.
