⚡ Bolt: Eliminate redundant API request for project lists#139aicoder2009 wants to merge 1 commit into
Conversation
- Eliminated redundant `/api/projects/[id]/lists` API request on the project details page (`src/app/projects/[id]/page.tsx`). - The project lists are now derived in-memory by filtering the globally fetched `allLists` array, removing an unnecessary network request and backend database query. - Documented this learning pattern in `.jules/bolt.md` to avoid fetching global collections and their subsets simultaneously.

📝 WalkthroughWalkthroughThe project detail page's data-loading logic is refactored to reduce backend requests. Instead of fetching the project and its lists sequentially via separate endpoints, the page now fetches project details and the full lists collection concurrently, then filters lists in-memory to derive the project-specific subset. This optimization and its design rationale are documented together. ChangesAvoid Redundant API Calls via In-Memory Filtering

Pull request overview
This PR optimizes the project detail page’s data fetching by removing the dedicated “project lists” API request and deriving the project-specific lists from the global /api/lists response instead.
Changes:
- Removed the
/api/projects/[id]/listsGET request from the project detail page’s initial load. - Derived
listsin-memory by filtering theallListsresult byprojectId. - Added an internal “Bolt” note documenting the pattern of avoiding redundant frontend API queries.

Handle failed /api/lists responses explicitly.
If allListsResult.success is false, the page currently renders with an empty lists state, which can incorrectly imply the project has no lists. Surface the error and clear list state deterministically.
Suggested fix

- const listsData = allListsResult.data as List[];
- setAllLists(listsData);
- setLists(listsData.filter((list) => list.projectId === projectId));

💡 What: Eliminated the
/api/projects/[id]/listsnetwork request on the project detail page by filtering the globalallListsresult in-memory.🎯 Why: The frontend previously fetched a global collection (
allLists) and its subset (lists) simultaneously via separate API requests. SinceallListsalready contained the required data, the secondary request caused unnecessary network overhead and an extra database query.📊 Impact: Reduces backend database queries, prevents redundant network latency, and marginally decreases Time to First Byte (TTFB).
🔬 Measurement: Verified by ensuring all tests pass (
pnpm test:run), frontend loads correctly without throwing errors, and by monitoring Network tab behaviour (expecting 1 fewer request to/api/projects/[id]/lists).PR created automatically by Jules for task 4954961390721112058 started by @aicoder2009
