Review the code changes in PR https://github.com/doctolib/treatment-plan/pull/3129

Context: This PR fixes a pub/sub event name mismatch. Three TPF toast helper files dispatched 'toasts:add' via GLOBAL_PUBSUB_REGISTRY, but the monolith's Toaster component subscribes to 'toaster:add'. The fix is a one-line change per file, plus new unit tests.

Changed files (all in /Users/USER/workspace/doctolib/treatment-plan on branch fhir-2233-fix-toast-event-name): 1. packages/tpf-national-health-records-ui/src/business/toast.ts 2. packages/tpf-national-health-records-ui/src/business/toast.test.ts 3. packages/tpf-nhr-fr/src/components/dmp-consultation-consent-view/toast.ts 4. packages/tpf-nhr-fr/src/components/dmp-consultation-consent-view/toast.test.ts 5. packages/tpf-prescription-fulfillments/src/business/eprescription/toast.ts 6. packages/tpf-prescription-fulfillments/src/business/eprescription/toast.test.ts

Review for: correctness, style compliance, CLAUDE.md guidelines, testing quality. Focus on any issues with the test approach (mocking GLOBAL_PUBSUB_REGISTRY) and whether the fix is complete.

Important finding. There's a Storybook preview file still using the old 'toasts:add' event name. Also the tpf-french-teleservices may have another dispatcher. Let me check those.

Found the critical issue. The Storybook preview file in tpf-nhr-fr is still subscribing to 'toasts:add', but the toast.ts in the same package now dispatches 'toaster:add'. This means Storybook previews will silently break — the ToastListener will no longer log toasts to the Actions panel because it's listening to the old event name.

Let me also verify the file with import type { ReactNode } vs React.ReactNode discrepancy.

Note: React.ReactNode is used without an explicit import * as React or import type { ReactNode } from 'react'. With jsx: "react-jsx", React doesn't need to be imported for JSX, but using React.ReactNode as a value reference does require the import. This was a pre-existing issue (not introduced by this PR), since the diff shows those lines were already using React.ReactNode.

Let me also confirm by looking at the original toast.ts content (before diff) to verify what was pre-existing.

Tools used:

  • Bash: git show main:packages/tpf-nhr-fr/src/components/dmp-consultation-consent-view/toast.ts 2>&1 | head -20

Tools used:

export type ToastProps = { message: React.ReactNode title: string uiStyle: 'info' | 'success' | 'error' | 'warning' action?: { message: string; onClick: () => void } }

export const addToast = (props: ToastProps) => { GLOBAL_PUBSUB_REGISTRY.dispatch({ type: 'toasts:add', payload: props }) }

Confirmed: the React.ReactNode usage was pre-existing. The PR did not introduce this issue, so I won't flag it.

Now let me check the test props to ensure they typecheck against the ToastProps type. Looking at the test, it passes { title, message, uiStyle } but ToastProps requires message: ReactNode | React.ReactNode. A string is a valid ReactNode, so that's fine. Let me also verify the comment removal is clean.

Now let me write up my review. Here are my findings:

Code Review: PR #3129 — fix(fhir-2233): align toast pub/sub event name with monolith toaster

Files reviewed: - /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-national-health-records-ui/src/business/toast.ts - /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-national-health-records-ui/src/business/toast.test.ts - /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-nhr-fr/src/components/dmp-consultation-consent-view/toast.ts - /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-nhr-fr/src/components/dmp-consultation-consent-view/toast.test.ts - /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-prescription-fulfillments/src/business/eprescription/toast.ts - /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-prescription-fulfillments/src/business/eprescription/toast.test.ts

Critical (90-100)

1. Storybook listener still subscribes to old event name — preview broken in tpf-nhr-fr — Confidence: 95

  • File: /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-nhr-fr/.storybook/preview.tsx:31
  • Issue: The fix in packages/tpf-nhr-fr/src/components/dmp-consultation-consent-view/toast.ts now dispatches 'toaster:add', but the colocated Storybook preview decorator is still subscribing to 'toasts:add': ```tsx const unsubscribe = GLOBAL_PUBSUB_REGISTRY.subscribe('toasts:add', (event) => { logToast(event.payload) })
The `ToastListener` decorator was specifically designed to catch what the monolith would catch (per its inline comment). Now Storybook will silently log nothing in the Actions panel when toasts are dispatched — DevEx regression and the design intent of mirroring the monolith subscription is lost. Update the subscribe call to `'toaster:add'` so the preview stays aligned with the new dispatch type and with the monolith.

### Important (80-89)

**2. Stale comment removed without explanation, while new dispatch type is now undocumented** — Confidence: 80

- File: `/Users/USER/workspace/doctolib/treatment-plan/packages/tpf-nhr-fr/src/components/dmp-consultation-consent-view/toast.ts:1-6` (before diff)
- The PR removes the JSDoc block that explicitly stated which event the monolith subscribes to. That comment was the load-bearing piece of context that made the original bug discoverable. Suggest replacing it with an updated version, e.g.:
```ts
/**
 * Toast utility for the DMP consultation consent View.
 *
 * Dispatches toast notifications via the global pub/sub registry.
 * The monolith Toaster component subscribes to 'toaster:add'.
 */

This both prevents the same regression (someone changing the event name back) and gives reviewers an obvious cross-reference to validate against the monolith.

3. Tests assert a coupling to a magic string but never centralize/share it — Confidence: 82

  • Files:
  • /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-national-health-records-ui/src/business/toast.test.ts:23,40
  • /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-nhr-fr/src/components/dmp-consultation-consent-view/toast.test.ts:23
  • /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-prescription-fulfillments/src/business/eprescription/toast.test.ts:23
  • The string 'toaster:add' is now duplicated in 6 places (3 source + 3 test files). The whole bug being fixed here is "string mismatch between producer and consumer." Tests as written only validate the producer matches itself — they will never catch a future drift from the monolith side. Consider:
  • extracting const TOASTER_ADD_EVENT = 'toaster:add' (shared in tpf-commons or a single source-of-truth module that the monolith can also consume), or
  • at minimum, defining the constant once per module and importing it into the test (so the test still asserts the literal string but not by re-typing it). This is the more elegant solution called for by the project's "Demand Elegance (Balanced)" principle when a fix touches a non-trivial coupling.

4. Test props in tpf-prescription-fulfillments and tpf-nhr-fr cover only one scenario and miss the optional-action branch — Confidence: 80

  • Files:
  • /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-nhr-fr/src/components/dmp-consultation-consent-view/toast.test.ts
  • /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-prescription-fulfillments/src/business/eprescription/toast.test.ts
  • Only tpf-national-health-records-ui has the second test covering the optional action prop. The other two packages have the same ToastProps shape (including action?), but their tests stop at the simple case. Per .claude/rules/testing/devex.md, the goal is meaningful behavior coverage, not test count — but here the three helpers are the same code with different homes, so the coverage should be uniform. Either:
  • mirror the second test (with optional action prop) into the other two files, or
  • collapse the three duplicates into one shared helper + one shared test (preferred — eliminates duplication entirely).

Notes (informational, not blocking)

  • The fix itself ('toasts:add' → 'toaster:add') is correct, minimal, and the right change per the PR description.
  • All three test files use a clean vi.mock pattern with afterEach(() => vi.clearAllMocks()) — consistent with .claude/rules/frontend/react/test/testing-patterns.md.
  • import type { ReactNode } is used in tpf-national-health-records-ui/src/business/toast.ts (good), while the other two files still use React.ReactNode without importing React. That latter pattern is pre-existing on main, not introduced by this PR — out of scope here, but worth a follow-up.
  • No CLAUDE.md violations (no eslint-disable, no any, no snapshot tests, no arbitrary waits, no CSS selectors).
  • Conventional Commits format on the commit message is correct: fix(fhir-2233): ....

Recommendation

Request changes for items 1 (definitely) and 3 (strongly preferred). The other two are nice-to-haves that materially improve maintenance characteristics. Item 1 is the only one that breaks behavior in a real environment (Storybook), and it should be fixed in this same PR since both the dispatch and the subscribe live in the same package.
