⚡ Bolt: Optimize project list fetching#190
Conversation
Derive a project's associated lists in-memory by filtering the global list of the user's lists on the frontend. This saves a redundant API call to `/api/projects/[id]/lists` and an identical DynamoDB full-table scan without requiring a new GSI.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Handle the allListsResult failure case.
The in-memory filter correctly mirrors the removed getProjectLists (fetch-all-then-filter) backend path, so the derivation itself is sound. However, when allListsResult.success is false (e.g. /api/lists returns 401/500), neither lists/allLists nor error is set, so the project silently renders the empty "This project has no lists yet" state. Surface the failure so users can distinguish a genuinely empty project from a failed list fetch.
🛡️ Proposed fix
if (allListsResult.success) {
setAllLists(allListsResult.data);
setLists(allListsResult.data.filter((list: List) => list.projectId === projectId));
+ } else {
+ setError(allListsResult.error || "Failed to load lists");

💡 What: Removed the explicit fetch to
/api/projects/[id]/listson thesrc/app/projects/[id]/page.tsxdetail page. The project's lists are now derived in-memory by filtering the user's global list response (allListsResult) using theprojectId.🎯 Why: Since DynamoDB currently lacks a Global Secondary Index (GSI) for
projectId, the backend/api/projects/[id]/listsendpoint retrieves the data by fetching all of a user's lists and filtering them anyway. Fetching/api/projects/[id]/listsalongside/api/listsresulted in duplicate API requests and duplicate backend table scans.📊 Impact: Reduces the frontend network request count on project load by 33% and halves the related read compute load on the backend for list data retrieval, speeding up page load time.
🔬 Measurement: View
src/app/projects/[id]/page.tsxrendering a project. You will see 2 API calls (/api/projects/[id]and/api/lists) instead of 3, with the list table correctly hydrated.PR created automatically by Jules for task 13235527304285623243 started by @aicoder2009
