Greptile Overview

Greptile Summary

Refactored user table to fix rerendering issues by implementing async state management, loading skeletons, and request deduplication.

• Converted from synchronous hook-based data fetching to async state-managed approach with isFetching flag and loading states
• Added loading skeleton rows with custom loading cells for avatar and actions columns
• Implemented request ID tracking to prevent race conditions and stale data updates
• Added externalRefreshKey prop to trigger table refresh when includeAnonymous filter changes
• Decoupled search input state from table state to prevent input lag using local state + deferred table updates

Confidence Score: 2/5

• This PR has a critical bug that will cause runtime errors when the table has no sorting applied
• Score reflects the critical sorting bug in user-table.tsx:223 where primarySort can be undefined, causing primarySort.id and primarySort.desc to throw errors. Also includes unused imports and ineffective setTimeout pattern
• apps/dashboard/src/components/data-table/user-table.tsx requires immediate attention to fix sorting logic bug

Learning: In the stack-auth codebase, use `runAsynchronouslyWithAlert` from `stackframe/stack-shared/dist/utils/promises` for async button click handlers and form submissions instead of manual try/catch blocks. This utility automatically handles errors and shows alerts to users.

Greptile Overview

Greptile Summary

Refactored user table to fix rerendering issues by moving from reactive state management to manual pagination with async data fetching. Added loading skeletons, debounced search, and external refresh key to reset pagination when includeAnonymous state changes.

Key changes:

• Replaced reactive useUsers hook with manual state management using useState and async listUsers calls
• Added request ID tracking to prevent race conditions from concurrent fetches
• Implemented loading states with skeleton placeholders for better UX
• Fixed cache invalidation by adding includeAnonymous parameter to cache key in useUsers hook
• Added externalRefreshKey to trigger pagination reset when underlying data changes

Confidence Score: 2/5

• Critical bug in sorting logic will cause runtime error if sorting state is ever cleared
• The PR contains a previously identified logic bug where primarySort.id is accessed without null checking (line 240), which will throw a runtime error if the sorting array is empty. While defaultSorting is provided, users can potentially clear sorting through UI interactions, making this a real risk.
• Pay close attention to apps/dashboard/src/components/data-table/user-table.tsx - the sorting logic bug on line 240 must be fixed before merging
