In /Users/USER/workspace/doctolib/doctolib/worktrees/FHIR-2020-implement-hl-findDocuments-api, I need to understand how DmpSharingService is initialized and what QueryClients it uses internally.

Please look at: 1. packages/@doctolib/dmp/src/hooks/DmpSharingService.ts - find the initializeDmpSharingService function or the DmpSharingService class constructor 2. How it sets up React Query - does it create its own QueryClient or use the singleton queryClientV5? 3. packages/@doctolib/dmp/src/hooks/tests/DmpSharingService.test.ts - find the initializeDmpSharingService helper function (around line 80-130) 4. Check if there are wrapper providers that create QueryClients (look for QueryClientProvider or ReactQueryWrapper in the test) 5. Look at the retry configuration for the queryClientV5 - in packages/@doctolib/shared_context/src/react-query/queryClientV5.ts, what are the default retry settings?

Report the exact file paths, function signatures, and relevant code snippets for each.

I'll systematically explore these files to understand DmpSharingService initialization and QueryClient setup.

Perfect! I have all the information I need. Let me compile my findings:

Summary Report: DmpSharingService Initialization and QueryClient Usage

1. DmpSharingService Class Constructor

File Path: /Users/USER/workspace/doctolib/doctolib/worktrees/FHIR-2020-implement-hl-findDocuments-api/packages/@doctolib/dmp/src/hooks/DmpSharingService.ts

Constructor Signature (lines 62-67):

constructor({ dmpApi, account, decryptFile, decryptRecord }: DmpSharingServiceConstructor) {
  this.dmpApi = dmpApi
  this.account = account
  this.decryptFile = decryptFile
  this.decryptRecord = decryptRecord
}

Constructor Type Definition (lines 36-41):

type DmpSharingServiceConstructor = {
  dmpApi: DmpApi
  account: Account
  decryptFile: DecryptFile
  decryptRecord: DecryptRecord
}

The DmpSharingService is a class that implements SharingHubService<DmpSharingOptionsInput, ItemType, string | undefined> and does NOT create or own any QueryClient. It receives dependencies injected through the constructor.

2. Test Helper: initializeDmpSharingService Function

File Path: /Users/USER/workspace/doctolib/doctolib/worktrees/FHIR-2020-implement-hl-findDocuments-api/packages/@doctolib/dmp/src/hooks/tests/DmpSharingService.test.ts

Function Signature (lines 1562-1574):

function initializeDmpSharingService() {
  const mockDmpApi = {
    share: mockedShareDocumentsOnDmp,
    unshare: mockedUnshareDocumentsOnDmp,
  } as unknown as DmpApi

  return new DmpSharingService({
    dmpApi: mockDmpApi,
    account: ACCOUNT,
    decryptFile: jest.fn(),
    decryptRecord: jest.fn((_, value) => Promise.resolve(value)) as unknown as DecryptRecord,
  })
}

No QueryClientProvider: The test helper directly instantiates DmpSharingService with mock dependencies. It does NOT wrap any component with QueryClientProvider or ReactQueryWrapper.

Singleton QueryClient Used: Tests access the global singleton queryClientV5 directly: - Line 22: import { queryClientV5 } from '@doctolib/shared_context' - Lines 91-93: await queryClientV5.cancelQueries(); queryClientV5.clear() - Line 295-302 and throughout: Tests directly query queryClientV5.getQueryState(queryKey)

3. Factory Hook: useDmpSharingServiceFactory

File Path: /Users/USER/workspace/doctolib/doctolib/worktrees/FHIR-2020-implement-hl-findDocuments-api/packages/@doctolib/dmp/src/hooks/useDmpSharingServiceFactory.ts

Key Function (lines 50-63):

const dmpSharingServiceFactory = useCallback(
  (hub: SharingHub) => {
    readyPromise.current
      ?.then(() => {
        hub.setReady(SharingServiceName.Dmp, true)
      })
      .catch((error: Error) => {
        console.error(error)
      })
    return new DmpSharingService({ dmpApi, account, decryptFile, decryptRecord })
  },
  [account, decryptFile, decryptRecord, dmpApi]
)

The factory hook: - Creates a DmpApi instance (line 36-48) via useMemo - Creates DmpSharingService instances on demand via a factory callback - Does NOT create or manage any QueryClient - it relies on the global singleton

4. React Query Configuration: queryClientV5 Retry Settings

File Path: /Users/USER/workspace/doctolib/doctolib/worktrees/FHIR-2020-implement-hl-findDocuments-api/packages/@doctolib/shared_context/src/react-query/queryClientV5.ts

File Path: /Users/USER/workspace/doctolib/doctolib/worktrees/FHIR-2020-implement-hl-findDocuments-api/packages/@doctolib/shared_context/src/react-query/config.ts

Default Options (lines 3-13 of config.ts):

export const queryClientDefaultOptions = {
  queries: {
    refetchOnWindowFocus: false,
    retry: false,  // <-- NO RETRIES
    networkMode: 'offlineFirst' as NetworkMode,
  },
  mutations: {
    retry: false,  // <-- NO RETRIES
    networkMode: 'offlineFirst' as NetworkMode,
  },
}

Key Findings: - retry: false - Queries and mutations do NOT retry on failure - refetchOnWindowFocus: false - Queries are not refetched when window regains focus - networkMode: 'offlineFirst' - Both queries and mutations use offline-first strategy

queryClientV5 Instantiation (lines 54-60 of queryClientV5.ts):

const queryClientOptions: QueryClientConfig = {
  defaultOptions: queryClientDefaultOptions,
  queryCache: new QueryCache(queryCacheOptionsV5),
  mutationCache: new MutationCache(mutationCacheOptionsV5),
}

export const queryClientV5 = new QueryClient(queryClientOptions)

5. Query Caching Behavior in Tests

The tests demonstrate that DmpSharingService indirectly relies on the global queryClientV5 singleton through React Query hooks. Query keys observed in tests: - ['ehr_rich_texts', 'sharing', 'rich_texts', 'index', { rich_text_ids: [...] }] - ['ehr_paper_forms', 'sharing', 'paper_forms', 'index', { paper_form_ids: [...] }] - ['dmp', 'documents', { document_id: ... }, 'fr_dmp_document', 'show'] - ['ehr_medication_requests', 'sharing', 'medication_requests', { medication_requests_ids: [...] }]

These queries use the shared queryClientV5 singleton with retry: false settings.

Architecture Summary

1. DmpSharingService - Pure domain class, no React/QueryClient knowledge
2. useDmpSharingServiceFactory - React hook that creates DmpSharingService instances
3. queryClientV5 - Global singleton QueryClient shared across the entire application
4. Retry Configuration - Disabled globally (retry: false) for both queries and mutations
5. No Local Providers - Tests and production code use the shared singleton, not local QueryClientProvider instances
