<objective>
Add click-through navigation from heatmap day cells to Kimai's timesheet view, and a project filter dropdown that re-fetches and re-renders the heatmap in place.
Purpose: Users can drill into specific days and filter their heatmap by project, making the widget actionable rather than just informational.
Output: Working click navigation, project filter dropdown, updated CSS and templates, rebuilt JS bundle.

**HeatmapService.php** — Add `getUserProjects(User $user): array` method that queries distinct projects the user has tracked time for:
```php
/**
* @return array<int, array{id: int, name: string}>
*/
public function getUserProjects(User $user): array
{
$qb = $this->repository->createQueryBuilder('t');
$qb->select('DISTINCT IDENTITY(t.project) as projectId, p.name')
->join('t.project', 'p')
->andWhere($qb->expr()->eq('t.user', ':user'))
->andWhere($qb->expr()->isNotNull('t.end'))
->setParameter('user', $user)
->orderBy('p.name', 'ASC');
return array_map(fn(array $row) => [
'id' => (int) $row['projectId'],
'name' => $row['name'],
], $qb->getQuery()->getResult());
}
```
**HeatmapWidget.php** — Remove `final` keyword (needed for testing). Inject `HeatmapService` via constructor. Update `getData()` to return project list. The `getUser()` method is inherited from `AbstractWidget` and is set by `WidgetExtension::renderWidget()` before `getData()` is called.
```php
use KimaiPlugin\KimaiHeatmapBundle\Service\HeatmapService;
class HeatmapWidget extends AbstractWidget
{
public function __construct(private readonly HeatmapService $service)
{
}
public function getData(array $options = []): mixed
{
$user = $this->getUser();
return [
'projects' => $this->service->getUserProjects($user),
];
}
// ... rest unchanged
}
```
**heatmap.html.twig** — Add two new `data-` attributes to the container div:
1. `data-projects` — JSON-encoded project list from `data.projects`
2. `data-timesheet-url` — Kimai timesheet base path via `path('timesheet')` (locale-safe, avoids hardcoding `/en/timesheet/`)
Updated template:
```twig
{% embed '@theme/embeds/card.html.twig' with {'margin_bottom': 0} %}
{% block box_title %}
{{ title }}
{% endblock %}
{% block box_body %}
<link rel="stylesheet" href="{{ asset('bundles/kimaiheatmap/heatmap.css') }}">
<div id="heatmap-container"
data-url="{{ path('heatmap_data') }}"

**assets/src/types.ts** — Add a `ProjectOption` interface:
```typescript
export interface ProjectOption {
id: number;
name: string;
}
```
**assets/src/heatmap.ts** — Major refactoring of `init()` and additions to `renderHeatmap()`:
1. **Add click handler** to the existing cell selection chain (after `.on('mouseleave', ...)` line). The handler constructs the Kimai timesheet URL using the `daterange` format `YYYY-MM-DD - YYYY-MM-DD` (same date repeated). It reads `timesheetUrl` from closure and appends `&projects[]=N` when a project filter is active.
Add `.on('click', ...)` to the cells selection chain at line ~193, right after the `.on('mouseleave', ...)`:
```typescript
.on('click', function (_event: MouseEvent, d: DayCell) {
if (!onCellClick) return;
onCellClick(d.dateStr);
})
```
2. **Add `onCellClick` parameter** to `renderHeatmap()` signature:
```typescript
export function renderHeatmap(
container: HTMLElement,
data: HeatmapData,
config: HeatmapConfig = DEFAULT_CONFIG,
onCellClick?: (dateStr: string) => void,
): void
```
3. **Add empty state for filtered results**. When `data.days` is empty, check if a `filteredEmpty` context flag is set. Add an optional `emptyMessage` parameter to `renderHeatmap`:
```typescript
export function renderHeatmap(
container: HTMLElement,
data: HeatmapData,
config: HeatmapConfig = DEFAULT_CONFIG,
onCellClick?: (dateStr: string) => void,
emptyMessage?: string,
): void
```
Use `emptyMessage || 'No tracking data available'` for the empty state text.
4. **Refactor `init()`** to:
- Parse `data-projects` JSON attribute into `ProjectOption[]`
- Parse `data-timesheet-url` attribute for the timesheet base path
- Track `activeProjectId: number | null = null` in closure scope
- Create a flex wrapper div with class `heatmap-wrapper`
- Create a `heatmap-svg-area` div for the SVG
- Create a `heatmap-filter` div with a `<select>` element (class `form-select form-select-sm`, `aria-label="Filter by project"`)
- Populate select with "All Projects" default (value `""`) + one option per project (`value=id`, text=name)
- Define `onCellClick` callback that constructs `{timesheetUrl}?daterange={encodeURIComponent(date + ' - ' + date)}` and appends `&projects[]={activeProjectId}` when filter is active, then assigns to `window.location.href`
- On initial fetch success, call `renderHeatmap(svgArea, data, DEFAULT_CONFIG, onCellClick)`
- On select `change` event: update `activeProjectId`, re-fetch from `{baseUrl}?project={id}` (or just `baseUrl` for "All Projects"), call `renderHeatmap(svgArea, newData, DEFAULT_CONFIG, onCellClick, 'No tracking data for this project')` on success
- Only create the filter dropdown if `projects.length > 0` (skip dropdown when no projects available)
- On fetch error, keep existing heatmap visible and log to console
Full `init()` rewrite:
```typescript
export function init(container: HTMLElement): void {
const baseUrl = container.getAttribute('data-url');
if (!baseUrl) {
console.error('KimaiHeatmap: missing data-url attribute');
return;
}
const timesheetUrl = container.getAttribute('data-timesheet-url') || '/en/timesheet/';
const projectsJson = container.getAttribute('data-projects');
const projects: ProjectOption[] = projectsJson ? JSON.parse(projectsJson) : [];
let activeProjectId: number | null = null;
const onCellClick = (dateStr: string): void => {
const daterange = `${dateStr} - ${dateStr}`;
let url = `${timesheetUrl}?daterange=${encodeURIComponent(daterange)}`;
if (activeProjectId) {
url += `&projects[]=${activeProjectId}`;
}
window.location.href = url;
};
// Build wrapper layout
container.innerHTML = '';
const wrapper = document.createElement('div');
wrapper.className = 'heatmap-wrapper';
const svgArea = document.createElement('div');
svgArea.className = 'heatmap-svg-area';
wrapper.appendChild(svgArea);
// Build filter dropdown (only if projects exist)
if (projects.length > 0) {
const filterDiv = document.createElement('div');
filterDiv.className = 'heatmap-filter';
const select = document.createElement('select');
select.className = 'form-select form-select-sm';
select.setAttribute('aria-label', 'Filter by project');
const defaultOpt = document.createElement('option');
defaultOpt.value = '';
defaultOpt.textContent = 'All Projects';
select.appendChild(defaultOpt);
for (const p of projects) {
const opt = document.createElement('option');
opt.value = String(p.id);
opt.textContent = p.name;
select.appendChild(opt);
}
select.addEventListener('change', () => {
const val = select.value;
activeProjectId = val ? parseInt(val, 10) : null;
const fetchUrl = val ? `${baseUrl}?project=${val}` : baseUrl;
fetch(fetchUrl)
.then(res => {
if (!res.ok) throw new Error(`HTTP ${res.status}`);
return res.json() as Promise<HeatmapData>;
})
.then(data => {
renderHeatmap(svgArea, data, DEFAULT_CONFIG, onCellClick, 'No tracking data for this project');
})
.catch(err => {
console.error('KimaiHeatmap: failed to load filtered data', err);
});
});
filterDiv.appendChild(select);
wrapper.appendChild(filterDiv);
}
container.appendChild(wrapper);
// Initial data fetch
fetch(baseUrl)
.then(res => {
if (!res.ok) throw new Error(`HTTP ${res.status}`);
return res.json() as Promise<HeatmapData>;
})
.then(data => {
renderHeatmap(svgArea, data, DEFAULT_CONFIG, onCellClick);
})
.catch(err => {
console.error('KimaiHeatmap: failed to load data', err);
svgArea.textContent = 'Failed to load heatmap data';
});
}
```
5. **Import `ProjectOption`** at top of heatmap.ts:
```typescript
import type { DayEntry, HeatmapData, HeatmapConfig, ProjectOption } from './types';
```
**Resources/public/heatmap.css** — Add click affordance and layout rules after existing styles:
```css
/* Click affordance */
.heatmap-cell {
cursor: pointer;
transition: opacity 0.1s ease;
pointer-events: fill;
}
.heatmap-cell:hover {
opacity: 0.75;
}
/* Layout: heatmap + filter side by side */
.heatmap-wrapper {
display: flex;
align-items: flex-start;
gap: 16px;
}
.heatmap-wrapper .heatmap-svg-area {
flex: 1;
min-width: 0;
overflow-x: auto;
}
.heatmap-wrapper .heatmap-filter {
flex-shrink: 0;
padding-top: 20px;
}
.heatmap-filter select {
min-width: 140px;
max-width: 200px;
}
```
Note: the existing `.heatmap-cell` rule (rx/ry) should be merged with the new properties. Keep `rx: 2; ry: 2;` and add `cursor`, `transition`, `pointer-events`.
6. **Rebuild JS bundle**: Run `npx esbuild assets/src/heatmap.ts --bundle --format=iife --global-name=KimaiHeatmap --outfile=Resources/public/heatmap.js --platform=browser` to produce the updated bundle.

## Trust Boundaries

| JS -> Kimai API | Fetch call to /heatmap/data with user-controlled ?project=N param |
| JS -> browser navigation | window.location.href assignment with constructed URL |
## STRIDE Threat Register
| Threat ID | Category | Component | Disposition | Mitigation Plan |
|-----------|----------|-----------|-------------|-----------------|
| T-04-01 | Tampering | data-projects attribute | accept | Data is rendered server-side by Twig from trusted DB query; client-side JSON.parse of server-provided data is safe |
| T-04-02 | Information Disclosure | /heatmap/data?project=N | accept | Controller already checks auth and user ownership via HeatmapService query filtering by user |
| T-04-03 | Spoofing | URL construction for navigation | mitigate | Use encodeURIComponent for daterange param; project ID is integer-only from select value |

- Test 3: All cells have cursor:pointer via the heatmap-cell class (verify class is applied)
- Test 4: init() with data-timesheet-url — clicking a cell sets window.location.href to `{timesheetUrl}?daterange={encodeURIComponent('YYYY-MM-DD - YYYY-MM-DD')}`
- Test 5: init() with active project filter — clicking a cell includes `&projects[]={id}` in the URL
- Test 6: init() without data-timesheet-url — falls back to `/en/timesheet/`

Create `assets/test/interaction.test.ts` with click navigation tests.
**Mock strategy:**
- For `renderHeatmap` tests: pass an `onCellClick` spy via `vi.fn()` and verify it's called with correct dateStr
- For `init()` tests: mock `global.fetch` to return mock HeatmapData, set `data-url`, `data-timesheet-url`, `data-projects` on container, use `Object.defineProperty(window, 'location', ...)` to capture href assignment
**Test structure:**

Adapt the exact mock patterns and async handling as needed when running against the actual implementation from Plan 01. Use `vi.waitFor()` to handle async fetch resolution.

Adapt mock patterns and async handling as needed. The key assertions are:
- `fetchMock.mock.calls[N][0]` checks the URL passed to fetch
- `container.querySelector('select.form-select')` checks dropdown presence
- `vi.waitFor()` handles async fetch/render cycles
