Explore two things in parallel:

  1. In /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-national-health-records-ui/src/: - Find and read NhrEntryPoint component (likely in components/ folder) - Find how NhrEntryPointProps is defined (search for "NhrEntryPointProps" type definition) - Look for any existing toast/notification usage - Search for "onError", "onSearchError", "errorCallback", or similar error callback props

  2. In /Users/USER/workspace/doctolib/oxygen/ (the design system): - List /Users/USER/workspace/doctolib/oxygen/packages/ - Find the Toast or Toaster component - Find how to trigger a toast programmatically (look for useToast, addToast, toast() function, etc.)

Also check the tpf package.json to understand what design system it uses for toasts.

Report: the full NhrEntryPoint component, the NhrEntryPointProps interface, and how toasts work in the oxygen design system.

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

Perfect! Now I have all the information. Let me compile the complete report:

Complete Report

I've explored both the NHR component and the Oxygen design system toast implementation. Here's what I found:

1. Full NhrEntryPoint Component

Location: /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-national-health-records-ui/src/components/NhrEntryPoint/NhrEntryPoint.tsx

import { useState } from 'react'

import type { ActionConfig, ColumnConfig, FilterConfig, NhrPatientInfo, SearchDocumentsFn } from '../../types'
import { NhrDocumentListModal } from '../NhrDocumentListModal/NhrDocumentListModal'
import { NhrEntryPointButton } from '../NhrEntryPointButton/NhrEntryPointButton'

export type NhrEntryPointProps = {
  patient: {
    show_ins_features?: boolean
  }
  patientInfo: NhrPatientInfo
  title: string
  columns: ColumnConfig[]
  filters: FilterConfig[]
  searchDocuments: SearchDocumentsFn
  actions?: ActionConfig[]
  newDocumentsCount?: number
  status: 'enabled' | 'disabled' | 'missing_requirements'
}

export const NhrEntryPoint = ({
  patient,
  patientInfo,
  title,
  columns,
  filters,
  searchDocuments,
  actions,
  newDocumentsCount = 0,
  status,
}: NhrEntryPointProps) => {
  const [isOpen, setIsOpen] = useState(false)

  // Patient eligibility: patient must have an active DMP
  if (!patient.show_ins_features || status !== 'enabled') return null

  return (
    <>
      <NhrEntryPointButton newDocumentsCount={newDocumentsCount} onClick={() => setIsOpen(true)} />
      <NhrDocumentListModal
        isOpen={isOpen}
        onClose={() => setIsOpen(false)}
        title={title}
        patient={patientInfo}
        columns={columns}
        filters={filters}
        searchDocuments={searchDocuments}
        actions={actions}
      />
    </>
  )
}

export default NhrEntryPoint

2. NhrEntryPointProps Interface

export type NhrEntryPointProps = {
  patient: {
    show_ins_features?: boolean
  }
  patientInfo: NhrPatientInfo
  title: string
  columns: ColumnConfig[]
  filters: FilterConfig[]
  searchDocuments: SearchDocumentsFn
  actions?: ActionConfig[]
  newDocumentsCount?: number
  status: 'enabled' | 'disabled' | 'missing_requirements'
}

Key points: - No error callback props (onError, onSearchError, etc.) — error handling is done internally via the searchDocuments callback return type - The SearchDocumentsFn returns a Promise with result type that includes status: NhrResultStatus and optional message and code fields - The component is a thin wrapper that opens/closes a modal containing the NhrDocumentListModal

3. Current Error Handling Pattern in NHR Package

Location: /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-national-health-records-ui/src/components/NhrDocumentListModal/NhrDocumentListModal.tsx

The NHR package already uses toast notifications for error handling:

async function fetchDocuments(
  searchDocuments: SearchDocumentsFn,
  appliedFilters: Record<string, unknown>,
  setDocumentsState: Dispatch<SetStateAction<DocumentsState>>
): Promise<void> {
  const result = await searchDocuments(appliedFilters)

  if (result.status === 'error') {
    setDocumentsState({ rows: [], total: undefined, isLoading: false })
    const errorTitle = 'Unable to load DMP documents'
    addToast({
      title: errorTitle,
      message: result.message ?? errorTitle,
      uiStyle: 'error',
    })
  } else {
    setDocumentsState({
      rows: result.data,
      total: result.total,
      isLoading: false,
    })
  }
}

It uses a custom local toast implementation defined in /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-national-health-records-ui/src/business/toast.ts:

import { GLOBAL_PUBSUB_REGISTRY } from '@doctolib/upfront-core'
import type { ReactNode } from 'react'

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

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

4. Oxygen Design System Toast Implementation

Location: /Users/USER/workspace/doctolib/oxygen/packages/toast/

The Oxygen design system provides a Toast system via pub/sub:

Main Export (/src/index.ts):

export { Toast } from '#components/Toast'
export { addToast, closeToast } from '#business/toast'

Business Logic (/src/business/toast.ts):

import { GLOBAL_PUBSUB_REGISTRY } from '@doctolib/upfront-core'
import { v4 as uuidV4 } from 'uuid'

import type { ToastProps } from './ToastQueue'

export const ADD_TOAST = 'toast:add'
export const CLOSE_TOAST = 'toast:close'

export function addToast(props: ToastProps): string {
  const id = uuidV4()
  GLOBAL_PUBSUB_REGISTRY.dispatch({ type: ADD_TOAST, payload: { ...props, id } })
  return id
}

export function closeToast(id: string) {
  GLOBAL_PUBSUB_REGISTRY.dispatch({ type: CLOSE_TOAST, payload: { id } })
}

Toast Props Type (/src/business/ToastQueue.ts):

export type ToastProps = {
  action?: Action
  dataWalkme?: string
  duration?: ToastDuration
  message?: ReactNode
  onClose?: () => void
  secondaryAction?: Action
  title?: string
  uiStyle?: ToastUIStyle
}

export type ToastDuration = number | 'infinite'

Toast Component (/src/components/Toast/Toast.tsx): - Listens to ADD_TOAST and CLOSE_TOAST events via pub/sub - Manages a toast queue with state management - Supports multiple toast display with animation support - Positioned via position: 'bottom-left' | 'top-left' - Renders to portal (document.body) - Default duration is configurable (defaults to 'infinite')

5. Design System Dependency

The TPF package.json shows the project uses:

{
  "dependencies": {
    "@doctolib/design-system": "^2.20.9",
    "@doctolib/design-system-b2b": "^1.5.0",
    "@doctolib/design-system-icons": "^2.18.0",
    ...
  }
}

Note: The Toast component is NOT listed as a separate dependency in the tpf-national-health-records-ui package.json. The NHR package implements its own addToast wrapper using GLOBAL_PUBSUB_REGISTRY, which is the same pub/sub mechanism Oxygen's Toast uses internally.

6. How to Trigger Toasts in Oxygen

Import and call:

import { addToast, closeToast } from '@doctolib/design-system'

// Show a toast
const toastId = addToast({
  title: 'Success',
  message: 'Operation completed',
  uiStyle: 'success',
  duration: 3000,
})

// Close the toast programmatically
closeToast(toastId)

Available UI styles: 'info', 'success', 'error', 'warning'

Toast must be rendered: The <Toast /> component must be mounted in your app (typically at the root level) with a position prop.
