Review the frontend architecture compliance for changed files in PR https://github.com/doctolib/treatment-plan/pull/3129 (branch: fhir-2233-fix-toast-event-name).

Changed files in /Users/USER/workspace/doctolib/treatment-plan: 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

The fix aligns the pub/sub event name from 'toasts:add' to 'toaster:add'. Check for UpFront architecture compliance: file placement in business/, naming conventions, test co-location, and any anti-patterns.

I'll review the changed files for UpFront architecture compliance. Let me read all six files in parallel.

Now I have a complete picture of all six changed files and their context. Here is the architecture review.

Architecture Review — PR #3129 (fhir-2233-fix-toast-event-name)

Summary

The PR corrects the pub/sub event name from 'toasts:add' to 'toaster:add' across three packages. The bug fix itself is correct and consistent. The review below covers architecture compliance of the changed files independently of the fix's correctness.

Critical Issues (must fix)

1. React.ReactNode used without import in two src/business/ files

Files: - /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-nhr-fr/src/components/dmp-consultation-consent-view/toast.ts (line 4) - /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-prescription-fulfillments/src/business/eprescription/toast.ts (line 4)

Both files reference React.ReactNode as a type without importing React:

type ToastProps = {
  message: React.ReactNode   // <-- global React namespace assumed
  ...
}

The tpf-national-health-records-ui version correctly imports the type explicitly:

import type { ReactNode } from 'react'

The implicit global React namespace works only because some tsconfig enables it (e.g., "jsx": "react" without "jsxImportSource"), which is a fragile assumption. The UpFront architecture requires explicit imports. Both files must be corrected to:

import type { ReactNode } from 'react'

type ToastProps = {
  message: ReactNode
  ...
}

2. src/business/ file imports from react in tpf-national-health-records-ui

File: /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-national-health-records-ui/src/business/toast.ts (line 2)

import type { ReactNode } from 'react'

The UpFront src/business/ layer rule states: pure functions only, no React imports. ReactNode is a React type, and importing it — even as a type-only import — introduces a React dependency into the business layer. The ToastProps type that wraps ReactNode belongs at the component boundary, not in src/business/.

The clean fix is to replace ReactNode with React.ReactNode only at the call site, or more correctly, to move the ToastProps type definition out of the business layer entirely. The addToast function in src/business/ should accept a plain-typed payload. If the toast payload truly must accept arbitrary React nodes in the message field, the wrapping type belongs in the component layer that calls addToast.

Warnings (should fix)

3. Mismatched function declaration style across packages

  • tpf-national-health-records-ui and tpf-nhr-fr use function addToast(...) (function declaration).
  • tpf-prescription-fulfillments uses export const addToast = (props: ToastProps) => { ... } (arrow function expression).

File: /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-prescription-fulfillments/src/business/eprescription/toast.ts (line 10)

While this is not a critical violation, function declarations are preferred in UpFront for module-level exports because they are hoisted and more readable in src/business/. Align to the majority pattern:

export function addToast(props: ToastProps) {
  GLOBAL_PUBSUB_REGISTRY.dispatch({ type: 'toaster:add', payload: props })
}

4. tpf-nhr-fr toast.ts is placed component-local but lacks the .helpers.ts naming convention

File: /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-nhr-fr/src/components/dmp-consultation-consent-view/toast.ts

The UpFront component directory pattern names component-local helper files as ComponentName.helpers.ts. A standalone toast.ts alongside dmp-consultation-consent-view.tsx does not follow this convention. It should either:

  • Be renamed to dmp-consultation-consent-view.helpers.ts (or folded into an existing one if it exists), or
  • If addToast is reused beyond this component, be promoted to src/business/ (as the other two packages have done).

Given that tpf-nhr-fr already has a src/business/ layer with non-trivial logic, and the component's own comment ("Owns all side effects: toasts…") frames toast-firing as a side-effect responsibility of the component, the component-local placement is acceptable — but the file name is wrong.

5. tpf-prescription-fulfillments toast.ts located inside src/business/eprescription/ subdirectory

File: /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-prescription-fulfillments/src/business/eprescription/toast.ts

The eprescription/ subdirectory inside src/business/ is an existing structural pattern in this package (it is a large facet). This does not violate UpFront rules in itself. However, the toast.ts file is a generic pub/sub dispatcher — it is not eprescription-specific domain logic. Placing a package-wide utility inside a domain subfolder implies a false dependency. If addToast is or could be needed outside the eprescription/ facet, it should sit at src/business/toast.ts directly.

6. ToastProps type is not exported in tpf-national-health-records-ui and tpf-nhr-fr

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

Only tpf-prescription-fulfillments exports ToastProps. In the other two files, ToastProps is private to the module. This means callers cannot type their arguments against the contract without duplicating the type or using Parameters<typeof addToast>[0]. Exporting the type is preferable for consistency:

export type ToastProps = { ... }

Suggestions (consider improving)

7. Duplicated ToastProps type definition across all three packages

The identical ToastProps shape (with message, title, uiStyle, optional action) is defined three times independently. If these packages share a common foundation package (e.g., tpf-commons), this type belongs there and should be imported rather than re-declared. This is not a violation in the current PR scope, but the duplication is a maintenance risk — any future field addition to the toast contract requires three synchronised changes.

8. Test coverage asymmetry between packages

  • tpf-national-health-records-ui/src/business/toast.test.ts covers both the base case and the optional action prop (2 tests).
  • tpf-nhr-fr and tpf-prescription-fulfillments test files cover only the base case (1 test each).

The optional action prop is part of the exported contract. Adding a second test case for the action prop to the two thinner test files would bring them to parity.

Conclusion

The event-name fix ('toasts:add' → 'toaster:add') is correct and consistently applied. The two critical issues — implicit React.ReactNode global and React import inside src/business/ — must be addressed before merge. The warnings around naming convention (toast.ts vs .helpers.ts) and arrow vs function declaration style are straightforward to resolve.
