Here is my review. --- PR #2807 Review: NHR Document List Pagination (FHIR-2091) Files Reviewed - /packages/tpf-national-health-records-ui/src/components/NhrDocumentList/NhrDocumentList.tsx - /packages/tpf-national-health-records-ui/src/components/NhrDocumentList/NhrDocumentList.test.tsx - /packages/tpf-national-health-records-ui/src/components/NhrDocumentListModal/NhrDocumentListTable/NhrDocumentListTable.tsx - /packages/tpf-national-health-records-ui/src/components/NhrDocumentListModal/NhrDocumentListTable/NhrDocumentListTable.test.tsx - /packages/tpf-national-health-records-ui/src/components/NhrDocumentListModal/NhrDocumentListTable/NhrDocumentListTable.stories.tsx Summary This PR converts a previously non-functional pagination (hardcoded currentPage={1}, onPageChange={() => {}}) into working client-side pagination. The approach is: NhrDocumentList owns pagination state (currentPage), slices the data array, and passes the page/total/callback down to NhrDocumentListTable which passes them to the Pagination design system component. --- Critical (90-100) -- None found --- Important (80-89) 1. useEffect on data causes unnecessary page reset on every render when data is fetched via React Query (Confidence: 85) File: NhrDocumentList.tsx (lines in the diff around the useEffect) useEffect(() => { setCurrentPage(1) }, [data]) The data dependency is the array reference. When NhrDocumentListModal uses this component, data comes from useDocuments which returns data: rows = []. React Query returns a new array reference on every successful refetch (even if the content is identical), and the destructured default = [] creates a new reference on every render when data is undefined. This means: - When the hook is still loading (data is undefined), the fallback [] default in the destructure const { data: rows = [], isLoading } creates a new array each render, but NhrDocumentList receives data={rows} which is that new [] each time -- triggering the effect and resetting page to 1 repeatedly (though it is already 1 during loading, so no visible bug there). - More importantly, any React Query background refetch that returns the same data will produce a new array reference, resetting the user to page 1 unexpectedly. Suggested fix: Track data length or a data identity token instead: const dataLength = data?.length ?? 0 useEffect(() => { setCurrentPage(1) }, [dataLength]) Or even better, only reset when filters change (which the handleApplyFilters already does), and remove the useEffect entirely. The useEffect is also redundant with the setCurrentPage(1) inside handleApplyFilters for the filter-change case. --- 2. NhrDocumentListTableProps now requires currentPage, total, and onPageChange -- breaking change to the public component type (Confidence: 82) File: NhrDocumentListTable.tsx The NhrDocumentListTableProps type adds three required (non-optional) properties. While NhrDocumentListTable is not exported from the package index (only NhrDocumentList is exported), the type NhrDocumentListTableProps is exported from its own file and could be imported directly by consumers using deep imports. Within the monorepo, the only consumer is NhrDocumentList itself, so the practical risk is low. However, all existing tests had to be updated with defaultPaginationProps, which signals the contract change is non-trivial. Suggested improvement: Consider making the pagination props optional with sensible defaults to reduce coupling: currentPage?: number // default 1 total?: number // default rows.length onPageChange?: (page: number) => void // default no-op This would also make the Storybook story simpler and maintain the previous behavior when used standalone. --- 3. The PAGE_SIZE constant is duplicated across three files (Confidence: 80) The value 20 appears as: - const PAGE_SIZE = 20 in NhrDocumentList.tsx - const PAGE_SIZE = 20 in NhrDocumentListTable.stories.tsx - nbRowsPerPage={20} hardcoded in NhrDocumentListTable.tsx If these ever drift, the slice logic in the parent and the pagination display in the child will disagree, showing incorrect page counts or missing rows. Suggested fix: Extract PAGE_SIZE as a shared constant (e.g., in a constants file or exported from NhrDocumentListTable) and use it consistently in both the slicing logic and the Pagination component. --- Positive Observations - Test coverage is good: The PR adds tests for first page rendering, page navigation, and page reset on data change. These cover the core pagination scenarios. - Backwards compatibility at the public API level: NhrDocumentList (the only exported component) keeps all its existing props optional -- data and isLoading remain optional. The pagination is purely internal to the component. Existing consumers like NhrDocumentListModal do not need changes. - The slice logic is correct: data?.slice((currentPage - 1) PAGE_SIZE, currentPage * PAGE_SIZE) properly handles page boundaries. When data is undefined, pagedData is undefined (via optional chaining), which is fine since rows defaults to [] in the table component. - Filter reset logic is sound: handleApplyFilters correctly resets to page 1 when filters change, preventing a stale page number from showing an empty page after filtering narrows results. - The storybook additions are thorough: 50 mock documents and interactive pagination in the story provide good visual testing. Architecture Compliance This is a frontend-only change within a single UI package. No hexagonal architecture concerns apply. The component hierarchy remains clean: NhrDocumentListModal -> NhrDocumentList (state owner) -> NhrDocumentListTable (presentational). Overall Assessment The PR is well-structured and implements client-side pagination correctly. The most actionable issue is item 1 (the useEffect on data reference) which could cause unexpected page resets in production when React Query refetches. I would recommend addressing that before merge. Items 2 and 3 are lower priority improvements.
