# Code Generation Plan — Unit 4: Dashboard
|
||||
|
||||
**Status**: ✅ Complete
|
||||
|
||||
## Unit Context
|
||||
|
||||
**Unit**: Unit 4 — Dashboard
|
||||
**Type**: Frontend (React/TypeScript)
|
||||
**Depends on**: Unit 3 (AppLayout, AuthContext) — complete
|
||||
**Stories Covered**: FR-05 (availability widget on dashboard)
|
||||
|
||||
**Key Design Decisions** (from functional design):
|
||||
- `@tanstack/react-query` added as new dependency; `QueryClientProvider` wraps the app in `main.tsx`
|
||||
- `useAvailabilityStatus` uses `useQuery` with `staleTime: 30_000` ms
|
||||
- Error + stale data: show last known status with stale indicator + error banner with Retry
|
||||
- `AvailabilityStatus` type and `AvailabilityResponse` interface added to `api/types.ts`
|
||||
- MSW mock handler created for tests
|
||||
|
||||
**Files to Modify**:
|
||||
- `frontend/package.json` — add `@tanstack/react-query`
|
||||
- `frontend/src/main.tsx` — wrap with `QueryClientProvider`
|
||||
- `frontend/src/api/types.ts` — add `AvailabilityStatus`, `AvailabilityResponse`
|
||||
- `frontend/src/mocks/index.ts` — register availability handlers
|
||||
- `frontend/src/pages/DashboardPage.tsx` — replace placeholder with availability widget
|
||||
- `frontend/src/i18n/locales/en/translation.json` — add `availability.*` keys
|
||||
- `frontend/src/i18n/locales/nl/translation.json` — add `availability.*` keys
|
||||
|
||||
**Files to Create**:
|
||||
- `frontend/src/api/useAvailability.ts`
|
||||
- `frontend/src/components/shared/AvailabilityStatusBadge.tsx`
|
||||
- `frontend/src/mocks/availability/handlers.ts`
|
||||
- `frontend/src/api/useAvailability.test.ts`
|
||||
- `frontend/src/components/shared/AvailabilityStatusBadge.test.tsx`
|
||||
- `aidlc-docs/features/cms-frontend/construction/unit-4/code/code-generation-summary.md`
|
||||

|
||||
|
||||
## Code Generation Steps
|
||||
|
||||
### Step 1: Install `@tanstack/react-query`
|
||||
- [x] Run `pnpm add @tanstack/react-query` in `frontend/`
|
||||
- [x] Verify `package.json` updated with `@tanstack/react-query`
|
||||
|
||||
### Step 2: Add `AvailabilityStatus` and `AvailabilityResponse` to `api/types.ts`
|
||||
- [x] Append to `frontend/src/api/types.ts`:
|
||||
```ts
|
||||
export type AvailabilityStatus = 'Available' | 'Maintenance' | 'Unavailable';
|
||||
|
||||
export interface AvailabilityResponse {
|
||||
status: AvailabilityStatus;
|
||||
checkedAt: string; // ISO 8601
|
||||
message: string;
|
||||
}
|
||||
```
|
||||
|
||||
### Step 3: Wrap app with `QueryClientProvider` in `main.tsx`
|
||||
- [x] Import `QueryClient`, `QueryClientProvider` from `@tanstack/react-query`
|
||||
- [x] Create `queryClient` instance with `defaultOptions: { queries: { retry: 1, refetchOnWindowFocus: true } }`
|
||||
- [x] Wrap `<AuthProvider>` with `<QueryClientProvider client={queryClient}>`
|
||||
|
||||
### Step 4: Create `useAvailability.ts`
|
||||
- [x] Create `frontend/src/api/useAvailability.ts`
|
||||
- [x] Implement `useAvailabilityStatus()` using `useQuery`:
|
||||
- `queryKey: ['availability', 'status']`
|
||||
- `queryFn`: `api.get<AvailabilityResponse>('/api/v1/Availability/status')`
|
||||
- `staleTime: 30_000`
|
||||
- [x] Return full TanStack Query result (`data`, `error`, `isLoading`, `isError`, `isFetching`, `refetch`)
|
||||
|
||||
### Step 5: Create `AvailabilityStatusBadge.tsx`
|
||||
- [x] Create `frontend/src/components/shared/AvailabilityStatusBadge.tsx`
|
||||
- [x] Props: `status: AvailabilityStatus`, `message?: string`, `stale?: boolean`
|
||||
- [x] Status → color/icon mapping:
|
||||
- `Available` → `bg-green-100 text-green-800 dark:bg-green-900 dark:text-green-200` + `CheckCircle` icon
|
||||
- `Maintenance` → `bg-amber-100 text-amber-800 dark:bg-amber-900 dark:text-amber-200` + `AlertTriangle` icon
|
||||
- `Unavailable` → `bg-red-100 text-red-800 dark:bg-red-900 dark:text-red-200` + `XCircle` icon
|
||||
- [x] Show `message` as subtitle paragraph when non-empty (`data-testid="availability-message"`)
|
||||
- [x] When `stale={true}`: amber dashed border + `Clock` icon + `t('availability.staleLabel')` label (`data-testid="availability-stale-indicator"`)
|
||||
- [x] Test IDs: `availability-badge` (wrapper), `availability-status-label`
|
||||
|
||||
### Step 6: Update `DashboardPage.tsx`
|
||||
- [x] Import `useAvailabilityStatus`, `AvailabilityStatusBadge` and `Card*` components
|
||||
- [x] Replace generic placeholder `Card` with the availability widget:
|
||||
- Card title: `t('availability.title')`
|
||||
- `isLoading` → skeleton placeholder (`data-testid="availability-skeleton"`)
|
||||
- `data` present → `<AvailabilityStatusBadge status={data.status} message={data.message} stale={isError} />`
|
||||
- `isError && !data` → error-only state: `t('availability.errorTitle')` + Retry button
|
||||
- `isError` (any) → error banner below/above badge with Retry button (`data-testid="availability-error"`, `data-testid="availability-retry"`)
|
||||
- [x] Keep welcome header section unchanged
|
||||
|
||||
### Step 7: Add i18n keys
|
||||
- [x] Add to `frontend/src/i18n/locales/en/translation.json`:
|
||||
```json
|
||||
"availability": {
|
||||
"title": "System Status",
|
||||
"available": "Available",
|
||||
"maintenance": "Maintenance",
|
||||
"unavailable": "Unavailable",
|
||||
"errorTitle": "Could not load status",
|
||||
"staleLabel": "Last known status",
|
||||
"retry": "Retry"
|
||||
}
|
||||
```
|
||||
- [x] Add to `frontend/src/i18n/locales/nl/translation.json`:
|
||||
```json
|
||||
"availability": {
|
||||
"title": "Systeemstatus",
|
||||
"available": "Beschikbaar",
|
||||
"maintenance": "Onderhoud",
|
||||
"unavailable": "Niet beschikbaar",
|
||||
"errorTitle": "Status kon niet worden geladen",
|
||||
"staleLabel": "Laatste bekende status",
|
||||
"retry": "Opnieuw proberen"
|
||||
}
|
||||
```
|
||||
|
||||
### Step 8: Create MSW availability handler
|
||||
- [x] Create `frontend/src/mocks/availability/handlers.ts`:
|
||||
```ts
|
||||
import { http, HttpResponse } from 'msw';
|
||||
export const availabilityHandlers = [
|
||||
http.get('*/Availability/status', () =>
|
||||
HttpResponse.json({
|
||||
status: 'Available',
|
||||
checkedAt: new Date().toISOString(),
|
||||
message: '',
|
||||
})
|
||||
),
|
||||
];
|
||||
```
|
||||
- [x] Modify `frontend/src/mocks/index.ts`:
|
||||
- Import `availabilityHandlers`
|
||||
- Spread into `handlers` array
|
||||
- Re-export `availabilityHandlers`
|
||||
|
||||
### Step 9: Tests — `useAvailabilityStatus`
|
||||
- [x] Create `frontend/src/api/useAvailability.test.ts`
|
||||
- [x] Test cases (using MSW + `renderHook` with `QueryClientProvider` wrapper):
|
||||
- Returns `isLoading=true` initially
|
||||
- Returns `data` on successful fetch (using default MSW handler)
|
||||
- Returns `isError=true` + preserves stale `data` on refetch failure (override handler to return 500)
|
||||
- `refetch()` triggers a new fetch
|
||||
|
||||
### Step 10: Tests — `AvailabilityStatusBadge`
|
||||
- [x] Create `frontend/src/components/shared/AvailabilityStatusBadge.test.tsx`
|
||||
- [x] Test cases:
|
||||
- `Available` → green badge, `t('availability.available')` label
|
||||
- `Maintenance` → amber badge, `t('availability.maintenance')` label
|
||||
- `Unavailable` → red badge, `t('availability.unavailable')` label
|
||||
- `message` prop: renders subtitle when non-empty, hidden when empty
|
||||
- `stale={true}`: renders stale indicator
|
||||
- `stale={false}` (default): no stale indicator
|
||||
|
||||
### Step 11: Final verification
|
||||
- [x] `pnpm build` — no TypeScript or Vite errors
|
||||
- [x] `pnpm lint` — no ESLint errors
|
||||
- [x] `pnpm test` — all tests pass (existing + new)
|
||||
- [x] Dev server: verify availability widget renders on dashboard, skeleton visible on load, Retry button functional
|
||||
|
||||
### Step 12: Write code generation summary
|
||||
- [x] Create `aidlc-docs/features/cms-frontend/construction/unit-4/code/code-generation-summary.md`
|
||||
- [x] List all created/modified files with paths
|
||||
- [x] Record test results
|
||||
|
||||
### Step 13: Commit
|
||||
- [x] Commit with message referencing Unit 4 / FR-05

# Functional Design Plan — Unit 4: Dashboard
|
||||
|
||||
**Status**: 🚧 In Progress
|
||||
|
||||
## Unit Context
|
||||
|
||||
**Unit**: Unit 4 — Dashboard
|
||||
**Type**: Frontend (React/TypeScript)
|
||||
**Depends on**: Unit 3 (AppLayout, AuthContext)
|
||||
**Stories Covered**: US-05 (FR-05 — Dashboard with availability widget)
|
||||
|
||||
**Key Deliverables**:
|
||||
- `frontend/src/api/useAvailability.ts` — `useAvailabilityStatus` hook with auto-refresh
|
||||
- `frontend/src/components/shared/AvailabilityStatusBadge.tsx` — colored status badge
|
||||
- Update `frontend/src/pages/DashboardPage.tsx` — replace placeholder with availability widget
|
||||
- `frontend/src/mocks/availability/handlers.ts` — MSW mock for tests
|
||||
- i18n keys for availability widget (en + nl)
|
||||
- Unit tests
|
||||
|
||||
**API Endpoint**:
|
||||
- `GET /api/v1/Availability/status` → `{ status: "Available" | "Maintenance" | "Unavailable", checkedAt: string, message: string }`
|
||||
|
||||
**Note**: `routes/index.tsx` from unit-of-work.md maps to `pages/DashboardPage.tsx` in the actual project structure (code-based router, not file-based).
|
||||

## Questions
|
||||
|
||||
Please fill in the letter after each `[Answer]:` tag.
|
||||
|
||||
---
|
||||
|
||||
### Question 1: Availability message display
|
||||
|
||||
The API returns a `message` field alongside the status. When/how should this message be shown?
|
||||
|
||||
A) Display the message as a subtitle below the status badge — always visible when non-empty (recommended — informative without cluttering the UI)
|
||||
B) Show the message as a tooltip on hover/focus over the badge — only visible on interaction
|
||||
C) Do not display the `message` field — show status text only
|
||||
D) Other
|
||||
|
||||
[Answer]: A
|
||||
|
||||
---
|
||||
|
||||
### Question 2: Error state when availability fetch fails
|
||||
|
||||
If `GET /availability/status` returns an error or the network is unreachable, what should the dashboard show?
|
||||
|
||||
A) An error card with a generic "Could not load availability status" message + Retry button (recommended — communicates the issue without crashing; consistent with global error pattern)
|
||||
B) Hide the availability widget silently — show nothing in its place
|
||||
C) Show the last successfully fetched status with a "stale" indicator (clock icon or "last updated X ago")
|
||||
D) Other
|
||||
|
||||
[Answer]: D, A combination of A and C. Show the error message with a retry button, but also tell the user the last fetched status for clarity
|
||||
|
||||
---
|
||||
|
||||
### Question 3: Auto-refresh interval
|
||||
|
||||
The unit-of-work specifies "staleTime: 30s". Since there is no TanStack Query, this will be implemented as `setInterval`. Should the hook auto-refresh while the component is mounted?
|
||||
|
||||
A) Yes — poll every 30 seconds while mounted (recommended — keeps dashboard current without manual refresh)
|
||||
B) Yes — but use a longer interval: 60 seconds
|
||||
C) No — fetch once on mount only; no auto-refresh (user can refresh the page)
|
||||
D) Other
|
||||
|
||||
[Answer]: D, try again to implement tanstack Query
|
||||
|
||||
---
|
||||
|
||||
### Question 4: AvailabilityStatus type location
|
||||
|
||||
Where should the `AvailabilityStatus` type and `AvailabilityResponse` interface be defined?
|
||||
|
||||
A) Add to `frontend/src/api/types.ts` — the shared types file (recommended — consistent with existing `User`, `AuthResponse`, `SetupStatus` types)
|
||||
B) Define inline in `useAvailability.ts` only — no shared types needed for this unit
|
||||
C) Other
|
||||
|
||||
[Answer]: A
|
||||
|
||||
---
|
||||
|
||||
### Question 5: Unit test scope
|
||||
|
||||
Which parts of Unit 4 should have unit tests?
|
||||
|
||||
A) `useAvailabilityStatus` hook (fetch, polling, error handling) + `AvailabilityStatusBadge` (renders correct colors/labels for each status) (recommended — covers all logic and UI variants)
|
||||
B) Only `AvailabilityStatusBadge` — skip hook tests (hook logic is simple enough to trust without tests)
|
||||
C) Full integration test: DashboardPage renders with availability widget (using MSW mock)
|
||||
D) Other

|
||||
|
||||
## Files Created
|
||||
|
||||
| File | Purpose |
|
||||
|---|---|
|
||||
| `frontend/src/api/useAvailability.ts` | `useAvailabilityStatus` hook (TanStack Query, staleTime 30s) |
|
||||
| `frontend/src/components/shared/AvailabilityStatusBadge.tsx` | Colored status badge with stale indicator |
|
||||
| `frontend/src/mocks/availability/handlers.ts` | MSW handler for `GET /Availability/status` |
|
||||
| `frontend/src/api/useAvailability.test.ts` | 4 hook tests (loading, success, error, refetch) |
|
||||
| `frontend/src/components/shared/AvailabilityStatusBadge.test.tsx` | 8 badge tests (all statuses, message, stale indicator) |
|
||||
| `aidlc-docs/features/cms-frontend/construction/unit-4/code/code-generation-summary.md` | This file |
|
||||
|
||||
## Files Modified
|
||||
|
||||
| File | Change |
|
||||
|---|---|
|
||||
| `frontend/package.json` | Added `@tanstack/react-query` 5.101.0 |
|
||||
| `frontend/src/main.tsx` | Wrapped app with `QueryClientProvider` |
|
||||
| `frontend/src/api/types.ts` | Added `AvailabilityStatus`, `AvailabilityResponse` |
|
||||
| `frontend/src/pages/DashboardPage.tsx` | Replaced placeholder card with availability widget |
|
||||
| `frontend/src/i18n/locales/en/translation.json` | Added `availability.*` keys |
|
||||
| `frontend/src/i18n/locales/nl/translation.json` | Added `availability.*` keys |
|
||||
| `frontend/src/mocks/index.ts` | Registered `availabilityHandlers` |
|
||||
| `frontend/src/test/utils.tsx` | Added `QueryClientProvider` to `renderWithProviders` and `renderApp` |
|
||||
|
||||
## Test Results
|
||||
|
||||
- **Total tests**: 55 / 55 passed
|
||||
- **Build**: ✅ clean (no TS errors)
|
||||
- **Lint**: ✅ clean
|
||||
|
||||
## Key Decisions Made During Generation
|
||||
|
||||
- `test/utils.tsx` updated to include `QueryClientProvider` — required by the 3 existing integration tests that render `DashboardPage` (RouteGuard.test.tsx, LoginPage.test.tsx)

# Business Logic Model — Unit 4: Dashboard
|
||||
|
||||
## Process Overview
|
||||
|
||||
Unit 4 introduces TanStack Query as a shared data-fetching layer and implements the Dashboard page with a live availability widget. The logic splits into three concerns: query infrastructure setup, the availability hook, and the dashboard UI composition.
|
||||
|
||||
---
|
||||
|
||||
## TanStack Query Setup
|
||||
|
||||
A `QueryClient` is created once at app startup and provided via `QueryClientProvider` wrapping the `RouterProvider` in `main.tsx`. This is a one-time global change that enables all future units to use `useQuery` / `useMutation`.
|
||||
|
||||
```ts
|
||||
// Recommended default options for the QueryClient
|
||||
const queryClient = new QueryClient({
|
||||
defaultOptions: {
|
||||
queries: {
|
||||
retry: 1,
|
||||
refetchOnWindowFocus: true,
|
||||
},
|
||||
},
|
||||
});
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## useAvailabilityStatus Hook
|
||||
|
||||
**Location**: `frontend/src/api/useAvailability.ts`
|
||||
|
||||
**Query key**: `['availability', 'status']`
|
||||
|
||||
**Fetch function**: Calls `GET /api/v1/Availability/status` via the shared `api` client.
|
||||
|
||||
**staleTime**: `30_000` ms — TanStack Query refetches automatically in the background once data is 30 seconds old.
|
||||
|
||||
**Return shape**:
|
||||
|
||||
```ts
|
||||
{
|
||||
data: AvailabilityResponse | undefined; // undefined until first successful fetch
|
||||
error: Error | null;
|
||||
isLoading: boolean; // true only during initial fetch with no data
|
||||
isFetching: boolean; // true during any in-flight refetch
|
||||
isError: boolean;
|
||||
refetch: () => void; // exposed for Retry button
|
||||
}
|
||||
```
|
||||
|
||||
**Stale-with-error state**: When a background refetch fails, TanStack Query preserves the previous `data` value while setting `isError = true`. This enables the dashboard to display the last known status alongside the error state (BR-U4-11).
|
||||
|
||||
---
|
||||
|
||||
## DashboardPage Composition
|
||||
|
||||
The DashboardPage composes existing layout primitives with the new availability widget. No routing changes are needed — `DashboardPage` is already registered as the `/dashboard` route component in `router.tsx`.
|
||||
|
||||
**Sections**:
|
||||
1. **Header** — welcome message with user name (already implemented; retained as-is)
|
||||
2. **Availability Widget** — replaces the generic placeholder card

||||

# Business Rules — Unit 4: Dashboard
|
||||
|
||||
## Access Rules
|
||||
|
||||
| ID | Rule |
|
||||
|---|---|
|
||||
| BR-U4-01 | The Dashboard is accessible to all authenticated users regardless of role |
|
||||
| BR-U4-02 | Unauthenticated users are redirected to `/login` by the existing `authenticatedRoute` guard |
|
||||
|
||||
## Data Fetching Rules
|
||||
|
||||
| ID | Rule |
|
||||
|---|---|
|
||||
| BR-U4-03 | Availability status is fetched via `GET /api/v1/Availability/status` on component mount |
|
||||
| BR-U4-04 | The query uses TanStack Query with `staleTime: 30_000` (30 seconds) — background refetch triggers automatically when data is stale |
|
||||
| BR-U4-05 | The endpoint is public (anonymous) — no Bearer token required; the API client still sends credentials for cookie consistency |
|
||||
|
||||
## Display Rules
|
||||
|
||||
| ID | Rule |
|
||||
|---|---|
|
||||
| BR-U4-06 | Status `Available` renders with a **green** visual indicator |
|
||||
| BR-U4-07 | Status `Maintenance` renders with an **amber/yellow** visual indicator |
|
||||
| BR-U4-08 | Status `Unavailable` renders with a **red** visual indicator |
|
||||
| BR-U4-09 | The `message` field is displayed as a subtitle below the status badge when it is a non-empty string |
|
||||
|
||||
## Error Handling Rules
|
||||
|
||||
| ID | Rule |
|
||||
|---|---|
|
||||
| BR-U4-10 | If the initial fetch fails (no cached data): display an error card with a generic message and a **Retry** button |
|
||||
| BR-U4-11 | If a background refetch fails but cached (stale) data exists: display the stale status badge with a visual "stale" indicator (e.g. amber border, clock icon) AND an error banner with a **Retry** button |
|
||||
| BR-U4-12 | Clicking the Retry button triggers an immediate refetch via TanStack Query's `refetch()` |
|
||||
| BR-U4-13 | Network errors and API errors are treated identically from a UI perspective — no internal error details are exposed to the user |
|
||||
|
||||
## Loading Rules
|
||||
|
||||
| ID | Rule |
|
||||
|---|---|
|
||||
| BR-U4-14 | While the initial fetch is in-flight (no cached data): display a skeleton/loading placeholder in the availability widget |
|
||||
| BR-U4-15 | Background refetches (when cached data exists) do not trigger a loading skeleton — the existing status remains visible |

# Domain Entities — Unit 4: Dashboard
|
||||
|
||||
## Entities
|
||||
|
||||
### AvailabilityStatus (enumeration)
|
||||
|
||||
A union type representing the three possible system states returned by the API.
|
||||
|
||||
| Value | Meaning |
|
||||
|---|---|
|
||||
| `Available` | System is fully operational |
|
||||
| `Maintenance` | System is in planned maintenance mode |
|
||||
| `Unavailable` | System is not accessible |
|
||||
|
||||
---
|
||||
|
||||
### AvailabilityResponse (API response shape)
|
||||
|
||||
Returned by `GET /api/v1/Availability/status`.
|
||||
|
||||
| Field | Type | Description |
|
||||
|---|---|---|
|
||||
| `status` | `AvailabilityStatus` | Current system status |
|
||||
| `checkedAt` | `string` (ISO 8601) | Timestamp when status was last evaluated |
|
||||
| `message` | `string` | Optional human-readable reason or note (may be empty string) |
|
||||

||||

|
||||

|
||||
style AvailabilityStatus fill:#2196F3,stroke:#0D47A1,color:#000
|
||||
```
|
||||
|
||||
AvailabilityResponse holds a status (one of three enumeration values) plus a timestamp and message.
|
||||
|
||||
---
|
||||
|
||||
## Type Placement
|
||||
|
||||
Both `AvailabilityStatus` and `AvailabilityResponse` are added to `frontend/src/api/types.ts` — the shared domain types file, consistent with `User`, `AuthResponse`, and `SetupStatus`.
|
||||
|
||||
---
|
||||
|
||||
## TanStack Query Dependency
|
||||
|
||||
`@tanstack/react-query` is added as a new production dependency. A shared `QueryClient` is configured in `main.tsx` and provided via `QueryClientProvider`. This enables `staleTime`, background refetching, and persistent cached data across error states.

|
||||
|
||||
## New / Modified Files
|
||||
|
||||
### 1. `frontend/src/main.tsx` (modify)
|
||||
|
||||
Add `QueryClientProvider` wrapping above `AuthProvider`. No other changes.
|
||||
|
||||
```tsx
|
||||
import { QueryClient, QueryClientProvider } from '@tanstack/react-query';
|
||||
|
||||
const queryClient = new QueryClient({
|
||||
defaultOptions: {
|
||||
queries: { retry: 1, refetchOnWindowFocus: true },
|
||||
},
|
||||
});
|
||||
|
||||
// Wrap existing tree:
|
||||
<QueryClientProvider client={queryClient}>
|
||||
<AuthProvider>
|
||||
<RouterProvider router={router} context={{ auth }} />
|
||||
</AuthProvider>
|
||||
</QueryClientProvider>
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 2. `frontend/src/api/types.ts` (modify)
|
||||
|
||||
Add two new types at the end of the file:
|
||||
|
||||
```ts
|
||||
export type AvailabilityStatus = 'Available' | 'Maintenance' | 'Unavailable';
|
||||
|
||||
export interface AvailabilityResponse {
|
||||
status: AvailabilityStatus;
|
||||
checkedAt: string; // ISO 8601
|
||||
message: string;
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 3. `frontend/src/api/useAvailability.ts` (new)
|
||||
|
||||
```ts
|
||||
import { useQuery } from '@tanstack/react-query';
|
||||
import { api } from '@/lib/api-client';
|
||||
import type { AvailabilityResponse } from './types';
|
||||
|
||||
export function useAvailabilityStatus() {
|
||||
return useQuery<AvailabilityResponse>({
|
||||
queryKey: ['availability', 'status'],
|
||||
queryFn: () => api.get<AvailabilityResponse>('/api/v1/Availability/status'),
|
||||
staleTime: 30_000,
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
**Return**: standard TanStack Query result (`data`, `error`, `isLoading`, `isError`, `isFetching`, `refetch`).
|
||||
|
||||
---
|
||||
|
||||
### 4. `frontend/src/components/shared/AvailabilityStatusBadge.tsx` (new)
|
||||
|
||||
**Props**:
|
||||
|
||||
| Prop | Type | Required | Description |
|
||||
|---|---|---|---|
|
||||
| `status` | `AvailabilityStatus` | Yes | Current status value |
|
||||
| `message` | `string` | No | Subtitle text below badge (only shown when non-empty) |
|
||||
| `stale` | `boolean` | No | When true, renders a stale-data visual indicator (amber border, clock icon) |
|
||||
|
||||
**Status → color mapping**:
|
||||
|
||||
| Status | Badge color class | Icon |
|
||||
|---|---|---|
|
||||
| `Available` | `bg-green-100 text-green-800 dark:bg-green-900 dark:text-green-200` | `CheckCircle` |
|
||||
| `Maintenance` | `bg-amber-100 text-amber-800 dark:bg-amber-900 dark:text-amber-200` | `AlertTriangle` |
|
||||
| `Unavailable` | `bg-red-100 text-red-800 dark:bg-red-900 dark:text-red-200` | `XCircle` |
|
||||
|
||||
**`stale` prop behavior**: When `stale={true}`, the badge wrapper gets an amber dashed border and a `Clock` icon + `t('availability.staleLabel')` label is rendered below the badge.
|
||||
|
||||
**Test IDs**:
|
||||
|
||||
| Element | `data-testid` |
|
||||
|---|---|
|
||||
| Badge wrapper | `availability-badge` |
|
||||
| Status label | `availability-status-label` |
|
||||
| Message subtitle | `availability-message` |
|
||||
| Stale indicator | `availability-stale-indicator` |
|
||||
|
||||

|
||||
|
||||
### 5. `frontend/src/pages/DashboardPage.tsx` (modify)
|
||||
|
||||
Replace the generic placeholder `Card` with the availability widget section.
|
||||
|
||||
**Conditional rendering logic**:
|
||||
|
||||
```
|
||||
if (isLoading) → show Skeleton in widget area
|
||||
if (isError && !data) → show error card with Retry (no status to show)
|
||||
if (data) → show AvailabilityStatusBadge
|
||||
if (isError) → also show stale indicator on badge + error banner with Retry
|
||||
```
|
||||
|
||||
**Layout sketch** (inside existing `space-y-6` wrapper):
|
||||
```
|
||||
[Welcome header — unchanged]
|
||||
[Card: title = t('availability.title')]
|
||||
[if isLoading] → skeleton placeholder
|
||||
[if !isLoading && data] → AvailabilityStatusBadge status={data.status} message={data.message} stale={isError}
|
||||
[if isError] → error banner (below badge if stale, full-card if no data) + Retry button
|
||||
```
|
||||
|
||||

|
||||
|
||||
### 6. `frontend/src/mocks/availability/handlers.ts` (new)
|
||||
|
||||
MSW handler for tests:
|
||||
|
||||
```ts
|
||||
import { http, HttpResponse } from 'msw';
|
||||
|
||||
export const availabilityHandlers = [
|
||||
http.get('*/Availability/status', () =>
|
||||
HttpResponse.json({
|
||||
status: 'Available',
|
||||
checkedAt: new Date().toISOString(),
|
||||
message: '',
|
||||
})
|
||||
),
|
||||
];
|
||||
```
|
||||
|
||||
Register in `frontend/src/mocks/browser.ts` and `frontend/src/mocks/server.ts`.
