Explore the Oxygen design system at /Users/USER/workspace/doctolib/oxygen/ to find toast notification components.

1. Search for "Toast", "toast", "notification", "Notification", "alert", "Alert" components in the packages directory
2. Find the toast component API - what props does it accept? How is it triggered?
3. Look for useToast, ToastProvider, toast() hooks or utilities
4. Check /Users/USER/workspace/doctolib/oxygen/packages/ for relevant packages
5. Look for any error-specific toast variants (error, warning, info, success)
6. Find any examples of how the toast is used in the monolith at /Users/USER/workspace/doctolib/doctolib/

Report the full component API, import paths, and usage examples.

Toast Notification Component API Report

Package Information

• Package Name: @doctolib/toast
• Version: 1.7.11
• Location: /Users/USER/workspace/doctolib/oxygen/packages/toast/
• Repository: https://github.com/doctolib/oxygen

Import Paths

// Main exports from the package
import { Toast } from '@doctolib/toast'
import { addToast, closeToast } from '@doctolib/toast'

// Internal component (less commonly used)
import { ToastCard, type ToastUIStyle } from '@doctolib/toast'

Core Component: Toast

Location: /Users/USER/workspace/doctolib/oxygen/packages/toast/src/components/Toast/Toast.tsx

Props:

{
  defaultDuration?: ToastDuration  // 'infinite' (default) | number (milliseconds)
  position: 'bottom-left' | 'top-left'  // Required
}

Usage Example:

import { Toast } from '@doctolib/toast'

// In your root React component
createRoot(domElement).render(
  <ReactQueryProvider httpClient={httpClient}>
    <DoctorDesktop />
    <Toast defaultDuration={getEnvironment() === 'test' ? 'infinite' : 5000} position="bottom-left" />
  </ReactQueryProvider>
)

Functions: addToast() and closeToast()

Location: /Users/USER/workspace/doctolib/oxygen/packages/toast/src/business/toast.ts

addToast(props: ToastProps): string

Triggers a toast notification and returns a unique toast ID.

Props:

type ToastProps = {
  action?: Action                    // Optional primary action
  dataWalkme?: string                // Optional WalkMe tracking attribute
  duration?: ToastDuration           // Override default duration (number | 'infinite')
  message?: ReactNode                // Toast message (required if no title)
  onClose?: () => void               // Callback when toast closes
  secondaryAction?: Action           // Optional secondary action
  title?: string                     // Toast title (required if no message)
  uiStyle?: ToastUIStyle            // 'info' | 'warning' | 'success' | 'error' | 'loading'
}

type Action = {
  dataWalkme?: string               // Optional WalkMe tracking attribute
  label: string                     // Button text
  onClick: MouseEventHandler        // Click handler (toast auto-closes after action)
}

type ToastDuration = number | 'infinite'
type ToastUIStyle = 'info' | 'warning' | 'success' | 'error' | 'loading'

Usage Examples:

import { addToast, closeToast } from '@doctolib/toast'

// Simple success toast
addToast({
  message: 'Flag key copied',
  uiStyle: 'success'
})

// Error toast
addToast({
  message: 'Failed to copy',
  uiStyle: 'error'
})

// Toast with title and message
addToast({
  title: 'Hello world',
  message: 'A wonderful toast message',
  uiStyle: 'info'
})

// Toast with action
const toastId = addToast({
  title: 'Save Changes?',
  message: 'You have unsaved changes',
  uiStyle: 'warning',
  action: {
    label: 'Save',
    onClick: (e) => {
      // Handle save
      console.log('Save clicked')
    }
  },
  secondaryAction: {
    label: 'Discard',
    onClick: (e) => {
      // Handle discard
    }
  }
})

// Toast with duration override
addToast({
  message: 'This will auto-dismiss',
  uiStyle: 'info',
  duration: 3000  // 3 seconds
})

// Toast with callback
addToast({
  message: 'Processing complete',
  uiStyle: 'success',
  onClose: () => {
    console.log('Toast was closed')
  }
})

// Loading toast
addToast({
  title: 'Processing',
  uiStyle: 'loading'
})

closeToast(id: string): void

Programmatically close a toast by its ID.

const toastId = addToast({ message: 'Processing...', uiStyle: 'loading' })

// Later, close it
closeToast(toastId)

Toast UI Styles

Each style has associated icons and colors:

Note: Error toasts automatically have role="alert" for accessibility. Other toasts use role="status".

Important Features

1. Duplicate Error Prevention: Duplicate error toasts with identical messages are automatically prevented.

2. Accessibility: - Toast container has aria-hidden attribute removed to ensure toasts are read by screen readers - Error toasts use role="alert" - Other toasts use role="status" - Title and message are associated with close button via aria-describedby

3. Timer Management: - Toasts pause their auto-dismiss timer on mouse enter - Toasts resume timer on mouse leave - In test environments, timers don't auto-dismiss

4. Action Behavior: When an action button is clicked, the toast automatically closes and the onClose callback is executed after the action handler.

5. Portal Rendering: Toasts are rendered via React Portal directly to document.body

Monolith Usage Examples

Location: /Users/USER/workspace/doctolib/doctolib-pro-desktop/src/core/flags/renderer/FlagsViewer.tsx

// Success toast
addToast({ message: 'Flag key copied', uiStyle: 'success' })

// Error toast
addToast({ message: 'Failed to copy', uiStyle: 'error' })

// Info toast with dynamic message
addToast({ message: `${Object.keys(flags).length} flags refreshed`, uiStyle: 'success' })

Setup Checklist

1. Install: npm install @doctolib/toast
2. Add <Toast /> component at the root level of your React app
3. Specify required position prop ('bottom-left' or 'top-left')
4. Optionally set defaultDuration (defaults to 'infinite')
5. Call addToast() from anywhere in your app to trigger notifications
6. Optionally use closeToast(id) to programmatically dismiss toasts
