# Frontend UI Patterns

См. также: [`frontend-shadcn.mdc`](frontend-shadcn.mdc), [`shadcn-mcp.mdc`](shadcn-mcp.mdc), [`reui-mcp.mdc`](reui-mcp.mdc), [Components](https://ui.shadcn.com/docs/components), [ReUI llms.txt](https://reui.io/llms.txt).

## Docs workflow (обязательно)

0. Codegraph / поиск существующих shared/domain / `reui-kit`
1. Skill ReUI + shadcn — component selection
2. **Primary:** MCP `user-reui` — search → `get_block` / `compose_page` (`surface: "frame"`) — **всегда cite `previewUrl` + `docsUrl`**
3. Primitives: MCP `plugin-shadcn-shadcn` + `pnpm dlx shadcn@latest docs <component>`
4. CLI: `cd apps/web && pnpm dlx shadcn@latest add @reui/...` → сверить API
5. Код по examples + docs (только после MCP ↔ docs)
6. Context7 — **только** TanStack Router/Query, Recharts
7. MCP `validate_usage` / `get_audit_checklist` — перед merge

## Surface

Проект использует **ReUI Frame** (`surface: frame`), не shadcn Card как оболочку list/ops-экранов. Эталон списка: [data-grid-filtering-2](https://reui.io/preview/base/data-grid-filtering-2).

## Обязательные референсы по зонам

| Зона | Preview |
|------|---------|
| KPI | [stats-12](https://reui.io/preview/base/stats-12) — EvoBGP hybrid SoT |
| Quick Actions | [stats-12](https://reui.io/preview/base/stats-12) · [card-12](https://reui.io/preview/base/card-12) → `QuickActionGrid` |
| List | [data-grid-filtering-2](https://reui.io/preview/base/data-grid-filtering-2) |
| Settings | [settings-16](https://reui.io/preview/base/settings-16), [Application Settings](https://reui.io/blocks/application/settings) |
| Settings rows / Health-check | [settings-2](https://reui.io/preview/base/settings-2), [settings-3](https://reui.io/preview/base/settings-3) |
| Auth | [auth-13](https://reui.io/preview/base/auth-13) |
| Empty | [empty-state-12](https://reui.io/preview/base/empty-state-12) |
| Forms | [form-7](https://reui.io/preview/base/form-7) |
| Shell | [app-shell-12](https://reui.io/preview/base/app-shell-12) |

**SettingRow:** `FieldSeparator` opt-in (`separated`); не между toggle-row и nested fields (Health-check). Settings-секции — отдельные Frame + `gap`, без hairline под PageHeader.

## Иерархия компонентов

## Матрица стандартизации

| Элемент | Shared | Primitive |
|---------|--------|-----------|
| Page wrapper | `PageShell` | — |
| List page | `ResourcePage` | ReUI `Frame` + `data-grid` + `filters` + shadcn `Tabs` `variant="line"` |
| Catalog / Board | `CatalogBoardToggle` + `ResourcePage` / `KanbanBoard` | `?view=board` на `/groups`, `/services` |
| Kanban | `KanbanBoard` / `KanbanBoardSkeleton` | ReUI `kanban` + `Frame` |
| Detail | `DetailPanel` | ReUI `Frame` |
| Settings | `SettingsShell` | — |
| Dashboard KPI | `OpsDashboard` / `KpiStatGrid` | ReUI Frame [stats-12](https://reui.io/preview/base/stats-12) hybrid |
| Quick Actions | `QuickActionGrid` | Frame tiles + Badge «Перейти» |
| Empty | `EmptyState` | `Empty` |
| Loading / Error | `QueryState` / kit skeletons | `Skeleton`, `Alert` |
| Status | `StatusBadge` | ReUI `Badge` (`success`/`info`/`warning`) |
| Create/Edit | `FormSheet` + `*-edit-sheet.tsx` | `Sheet`, `Field` |
| Form field | `FormField` | `Field`, `Input`, `Select` |
| Submit button | `LoadingButton` | `Button`, `Spinner` |
| Delete confirm | `ConfirmDialog` | `AlertDialog` |
| Nav | `AppSidebar` (`isActive` обязателен) | `Sidebar` |
| Breadcrumbs | `SiteHeader` | `Breadcrumb` |
| Dates | `lib/format.ts` | — |

## Header actions

Независимые CTA в header → `flex shrink-0 flex-wrap items-center justify-end gap-2`.

**Не** оборачивать в `ButtonGroup` (он склеивает кнопки). `ButtonGroup` — только для связанных контролок (filter chips и т.п.).

Max 1 primary (`default`) на экран; остальные `outline` / `ghost`.

Toggle «Доска» / «К каталогу» — всегда `outline` в `primaryAction` / `KanbanBoard.toolbarActions` (не отдельный Frame-shell).

## Line tabs (project standard)

Эталон: [c-tabs-2](https://reui.io/preview/base/components/c-tabs-2) + counted [filtering-2](https://reui.io/preview/base/data-grid-filtering-2).

```tsx
<TabsList variant="line" className="gap-5">
  <TabsTrigger value="…" className="text-muted-foreground hover:text-foreground h-auto gap-2 px-0 pb-3">
    <span>Label</span>
    <span className="bg-muted text-muted-foreground … tabular-nums rounded-md">{count}</span>
  </TabsTrigger>
</TabsList>
```

- Примитив: [`packages/ui/.../tabs.tsx`](../../packages/ui/src/components/tabs.tsx) — line = `h-auto`, без `flex-1`, без `dark:data-active:bg-input/30`, underline `after:bottom-0`
- Active = яркий текст + **foreground underline**, без фона
- Count pill всегда `bg-muted`
- Active state — Base UI `data-active`, не Radix `data-[state=active]`
- Не трогать internals `reui/date-selector`

## Catalog / Board (`/groups`, `/services`)

| Режим | UI | Search |
|-------|-----|--------|
| Catalog (default) | `ResourcePage` + primary create | omit / `view=catalog` |
| Board | `KanbanBoard` DnD | `?view=board` |

- Groups tabs: Все / С доменами / Пустые
- Services tabs: Все / Включены / Выключены / Без группы
- DnD только на board; kanban hooks/cards не удалять

## Dashboard KPI

Эталон: [stats-12](https://reui.io/preview/base/stats-12) — icon tile + value + label + optional badge/footer; клик через `to` (`Link`) / `onSelect`. Compact strip: [card-35](https://reui.io/preview/base/card-35).

## Sidebar

- Каждый `SidebarMenuButton` получает `isActive` от pathname (`useRouterState`)
- `--sidebar-accent` в `AppShell` — заметный mix primary (~14%), не 5%

## Overlay selection

| Сценарий | Компонент |
|----------|-----------|
| Create/edit форма | `Sheet` |
| Destructive confirm | `AlertDialog` via `ConfirmDialog` |
| Modal preview | `Dialog` |

## Block registry

| Зона | Block / эталон |
|------|----------------|
| Shell | [app-shell-12](https://reui.io/preview/base/app-shell-12) |
| List + tabs + filters | [data-grid-filtering-2](https://reui.io/preview/base/data-grid-filtering-2) |
| Line tabs | [c-tabs-2](https://reui.io/preview/base/components/c-tabs-2) |
| KPI | [stats-12](https://reui.io/preview/base/stats-12) — на dashboard, certificates, domains, groups, services |
| Login | [auth-13](https://reui.io/preview/base/auth-13) |
| Settings | [settings-16](https://reui.io/preview/base/settings-16) / [settings-6](https://reui.io/preview/base/settings-6) |
| Empty | [empty-state-12](https://reui.io/preview/base/empty-state-12) |

## Spacing

```
AppShell main: gap-4 md:gap-6, px-4 md:px-6, py-4 md:py-5
  (--sidebar-width: 240px; header h-12; AppSwitcher + AppsMenu — Shared App Shell chrome)
PageShell:     gap-4 md:gap-6
Title/desc:    gap-px
Card/Frame grid: gap-4 (dashboard denser: gap-2 md:gap-3)
FieldGroup:    gap-4
Item list:     gap-2
Toolbar / header actions: gap-2
Tabs list (line): gap-5
```

Shared chrome (vps-tracker / CDNManager / EvoBGP): см. [`docs/ui-design-contract.md`](../../docs/ui-design-contract.md) — секция **Shared App Shell chrome**. Preview: [app-shell-12](https://reui.io/preview/base/app-shell-12).

**Запрещено:** `space-y-*`, raw colors (`bg-emerald-*`), custom empty divs, page-level Spinner / plain «Загрузка…» без Skeleton.

## UX/UI (состояния данных)

Каждый блок: **default, hover, focus, disabled, empty, loading, error**.

- **Loading** — `Skeleton` / `ResourcePage` skeleton / `KanbanBoardSkeleton` / `OpsDashboard` skeleton, не Spinner на странице
- **Empty** — `EmptyState` с CTA
- **Zero-results** — message внутри DataGrid (+ «Сбросить»)
- **Error** — `QueryState` / `Alert` + `onRetry`
- **Overflow** — `truncate`, `max-w-*`, `Tooltip`; `tabular-nums` для чисел
- **Density** — operational (`dense` Frame/DataGrid); max 1 primary CTA
- **A11y** — `aria-invalid`, `aria-label`/`sr-only` на icon-only, `aria-current="page"` на active nav/settings

## Button hierarchy (max 1 primary per screen)

1. `default` — главный CTA
2. `outline` — вторичные действия
3. `ghost` / `link` — навигация, cancel
4. `destructive` — только с `ConfirmDialog`
