# @mezzanine-ui/react

> React component library for Mezzanine UI — a comprehensive set of accessible, themeable components built on top of @mezzanine-ui/core, @mezzanine-ui/icons, and @mezzanine-ui/system.

## Installation

```bash
npm install @mezzanine-ui/react @mezzanine-ui/core @mezzanine-ui/icons @mezzanine-ui/system react react-dom lodash
```

Peer dependencies: `react >= 18`, `react-dom >= 18`, `lodash >= 4`

| `@mezzanine-ui/core`     | CSS styles and TypeScript type definitions        |
| `@mezzanine-ui/icons`    | SVG icon definitions (plain objects)              |
| `@mezzanine-ui/system`   | Design tokens: palette, spacing, typography, etc. |

## Import Patterns

Individual component (preferred for tree-shaking):
```ts
import Button from '@mezzanine-ui/react/Button';
import Select from '@mezzanine-ui/react/Select';
```

Named exports from the barrel (hooks, types, utilities):
```ts
import { usePagination, useCheckboxControlValue } from '@mezzanine-ui/react';
import type { ButtonProps, ButtonVariant } from '@mezzanine-ui/react';
```

Required CSS — import per component's style entry from @mezzanine-ui/core:
```ts
import '@mezzanine-ui/core/button/styles';
import '@mezzanine-ui/core/select/styles';
```

## Component Categories

- **Navigation** — Breadcrumb, Drawer, Navigation (+ sub-components), PageHeader, PageFooter, Stepper, Tab
- **Data Display** — Accordion, Badge, Cards (BaseCard, FourThumbnailCard, SingleThumbnailCard, QuickActionCard), Description, Empty, Pagination, Table, Tag, Tooltip
- **Data Entry** — AutoComplete, Checkbox, DatePicker, DateRangePicker, DateTimePicker, FilterArea, FormField, Input, Radio, Select, Slider, Switch, Textarea, TimePicker, Upload, Cascader
- **Feedback** — InlineMessage, Message, Modal, NotificationCenter, Progress, ResultState, Skeleton, Spin
- **Others** — AlertBanner, Anchor, Backdrop, FloatingButton
- **Utility** — Calendar, Dropdown, Popper, Portal, TimePanel, Transition animations (Collapse, Fade, Rotate, Scale, Slide, Translate)

## Key Design Patterns

**Polymorphic `component` prop** — most components accept a `component` prop to override the rendered HTML element or pass a router link component:
```tsx
<Button component="a" href="/page">Link Button</Button>
```

**Controlled/uncontrolled with control hooks** — pair components with their corresponding hook:
```tsx
const [value, onChange] = useCheckboxControlValue({ defaultValue: [] });
<CheckboxGroup value={value} onChange={onChange} options={options} />
```

Available control hooks: `useAutoCompleteValueControl`, `useCheckboxControlValue`, `useInputControlValue`, `useInputWithClearControlValue`, `useRadioControlValue`, `useSelectValueControl`, `useSwitchControlValue`, `useCustomControlValue`.

**Portal-based overlays** — Modal, Drawer, and Tooltip render outside the component tree via `Portal`. Use the `container` prop to target a specific DOM node.

**Calendar adapter pattern** — Calendar components require a date adapter. Install one of `dayjs >= 1`, `moment >= 2`, or `luxon >= 3` and pass it to `CalendarConfigProvider`:
```tsx
import { CalendarConfigProvider } from '@mezzanine-ui/react';
import dayjs from 'dayjs';
<CalendarConfigProvider methods={dayjsMethods}>...</CalendarConfigProvider>
```

**forwardRef** — all components forward their ref to the underlying DOM element.
