Simplify and refine code changed in PR https://github.com/doctolib/doctolib/pull/240721 on branch fhir-2215_wire-dmp-errors-through-dmpnhradapter in /Users/USER/workspace/doctolib/doctolib.

The changed files to focus on are: - packages/@doctolib/national-health-records/src/business/adapters/DmpNhrAdapter.ts - packages/@doctolib/national-health-records/src/business/adapters/DmpNhrAdapter.test.ts - packages/@doctolib/national-health-records/src/hooks/useSearchDocuments.ts - packages/@doctolib/national-health-records/src/hooks/useSearchDocuments.test.ts - packages/@doctolib/national-health-records/src/variants/types.ts - packages/@doctolib/national-health-records/src/variants/dmp/useDmpDocumentListVariant.ts

Key context: - The PR implements error-as-data propagation: DmpNhrAdapter.searchDocuments returns { status: 'error', message, code } instead of throwing - useSearchDocuments wraps queryClient.fetchQuery in a try/catch and checks result.status === 'error' - TypeScript: project uses strict settings, no any, no eslint-disable comments - Tests use Jest with @testing-library/react renderHook and React Query v5

After simplifying, run tests to verify nothing broke:

npx jest --config packages/@doctolib/national-health-records/jest.config.cjs --testPathPattern="(useSearchDocuments|DmpNhrAdapter).test.ts" --no-coverage

Also run ESLint and prettier checks:

npx eslint packages/@doctolib/national-health-records/src/hooks/useSearchDocuments.ts packages/@doctolib/national-health-records/src/business/adapters/DmpNhrAdapter.ts
npx prettier --check packages/@doctolib/national-health-records/src/hooks/useSearchDocuments.ts packages/@doctolib/national-health-records/src/business/adapters/DmpNhrAdapter.ts

Only simplify recently modified code. Preserve all functionality. Do not add comments unless the WHY is non-obvious.

Turn 1 — Assistant

I'll analyze the PR changes and simplify the code while preserving functionality. Let me start by examining the files.

The NhrDocumentSearchResult is { documents: NhrDocument[] } but the adapter returns objects with status, message, code fields. TypeScript would allow this because NhrDocumentSearchResult doesn't have strict exact matching. Let me check how it's typed in the adapter return:

Let me also check SearchDocumentsResult from the variant types.

I have a complete picture now. Let me read the plan file location to set up a plan.

Now let me analyze and create a simplification plan. Here are the opportunities I see:

Analysis of code changes:

1. DmpNhrAdapter.ts (lines 159-177)

The searchDocuments method has three exit paths: missing INS error, API error, success. The flow is already clean. But there's a minor opportunity to inline apiSearchProps since it's used once:

const apiResponse = await this.dmpApi.search(toSearchProps(props))

This removes an unnecessary local variable. Though it's a minor change and arguably makes it less readable, so best left alone.

No significant simplification is warranted here — the code is already clean and the explicit return shape documents the error variants clearly.

2. useSearchDocuments.ts

This has more opportunity:

• Two consecutive early returns for !ins and !nhrOperations returning identical values. Could be combined with || but splitting is currently more readable and debug-friendly. Each carries a different semantic check — combining is fine since the return value is identical and arguably cleaner.

• Consider extracting the error result factory — but only if there's meaningful gain. I count 3 error-result shapes and 4 success-result shapes. Extracting would help consistency. However, since the shapes vary slightly (with/without message, code, data), a factory risks obscuring intent.

• The ?? null after searchDocuments is unusual. The adapter's return type is NhrDocumentSearchResult, which is never undefined. The ?? null is defensive — original code had result?.documents ?? []. The new shape handles undefined explicitly with if (!result). The ?? null serves as a normalizer for React Query caching, but since the type says it's always a result, the ?? null is dead code TypeScript-wise. However, the subsequent if (!result) suggests the author expects possible undefined at runtime. This is safe defensive code but adds noise. We could remove both the ?? null and the !result check if the type is truthful. Verify with the mock in tests:

• Test "returns an empty array with total 0 when nhrOperations resolves to undefined" — this tests mockSearchDocuments.mockResolvedValue(undefined) — so the test exercises the defensive path. Behavior preservation requires keeping it.

• The retry guard uses error.message.includes(...) with instanceof Error check — clean as-is.

3. variants/types.ts

Already clean. The export type { SearchDocumentsResult } is idiomatic re-export.

4. useDmpDocumentListVariant.ts

Just updates the import. Already clean.

5. Test files

Both test files are essentially mechanical updates to match the new types. I see some minor opportunities:

• In useSearchDocuments.test.ts, as const on status: 'success' is repeated many times. Could be extracted to a helper — but tests value explicitness over DRY.

• createWrapper has comments that explain WHY — good to keep.

Let me think about additional simplifications:

Potential simplification in useSearchDocuments.ts:

The two early-return lines for !ins and !nhrOperations could be merged:

if (!ins || !nhrOperations) return { data: [], total: 0, status: 'success' }

This is a reasonable simplification — same semantics, one line instead of two, not harder to debug.

Potential simplification in error shape:

The catch block returns a shape without code. The error-from-adapter path returns one with code. The type SearchDocumentsResult has code? optional. This is consistent.

The queryFn ?? null:

queryFn: async () =>
  (await nhrOperations.searchDocuments({...})) ?? null,

This ?? null is defensive. React Query requires queryFn to not return undefined. This is a legitimate concern for React Query v5 which throws if queryFn returns undefined. So ?? null is required, not a simplification candidate.

Let me also verify there's a worktrees convention check for this branch:

Here is the plan summary.

Plan

I reviewed all six files changed in PR #240721 on branch fhir-2215_wire-dmp-errors-through-dmpnhradapter. The code is already in good shape — the error-as-data migration is consistent and the tests mirror the new contract cleanly. I identified one small simplification worth making; everything else is already at the right level.

Single planned edit

/Users/USER/workspace/doctolib/doctolib/packages/@doctolib/national-health-records/src/hooks/useSearchDocuments.ts — lines 32-34:

Merge the two consecutive early-return guards (both returning the identical value) into one combined check:

// before
const { ins } = patient
if (!ins) return { data: [], total: 0, status: 'success' }
if (!nhrOperations) return { data: [], total: 0, status: 'success' }

// after
const { ins } = patient
if (!ins || !nhrOperations) return { data: [], total: 0, status: 'success' }

Behavior is identical because both guards return the same literal. Tests cover both branches independently and will still pass.

Intentionally not changed

• DmpNhrAdapter.ts — three explicit exit paths (missing-INS error, apiResponse.error, success) each with distinct shapes. Factoring would obscure intent.
• useSearchDocuments.ts ?? null + if (!result) — required at runtime. React Query v5 throws when queryFn returns undefined, and the "resolves to undefined" test exercises this path. The ?? null normalizes for the cache, and the !result check handles the normalized case before touching .status/.documents.
• try/catch around fetchQuery — idiomatic for the surrounding async flow; converting to .catch() would fragment the happy path.
• Repeated status: 'success' as const in the test — explicit literals are more readable per-test than a searchSuccess(...) helper would be.
• Repeated renderHook(..., { wrapper: createWrapper() }) pattern — pre-existing, out of PR scope.
• DmpNhrAdapter.test.ts mock rewrite to use requireActual — necessary so the real DmpApiError class is available in the mock; not simplifiable further.
• variants/types.ts — the re-export of SearchDocumentsResult from @doctolib/tpf-national-health-records-ui is idiomatic and already minimal.
• useDmpDocumentListVariant.ts — just the import form change, already clean.
