## Install

- use npm

```sh
npm i -S react-rnd
```

- use yarn

```sh
yarn add react-rnd
```

## Usage

### Example with `default`

``` javascript
<Rnd
  default={{
    x: 0,
    y: 0,
    width: 320,
    height: 200,
  }}
>
  Rnd
</Rnd>
```

### Example with `position` and `size`

``` javascript
<Rnd
  size={{ width: this.state.width,  height: this.state.height }}
  position={{ x: this.state.x, y: this.state.y }}
  onDragStop={(e, d) => { this.setState({ x: d.x, y: d.y }) }}
  onResizeStop={(e, direction, ref, delta, position) => {
    this.setState({
      width: ref.style.width,
      height: ref.style.height,
      ...position,
    });
  }}
>
  001
</Rnd>
```

## Props

#### `default: { x: number; y: number;  width?: number | string;  height?: number | string; };`

The `width` and `height` property is used to set the default size of the component.
For example, you can set `300`, `'300px'`, `50%`.
If omitted, set `'auto'`.

The `x` and `y` property is used to set the default position of the component.

#### `size?: { width: (number | string), height: (number | string) };`

The `size` property is used to set size of the component.
For example, you can set 300, '300px', 50%.

Use `size` if you need to control size state by yourself.

#### `position?: { x: number, y: number };`

The `position` property is used to set position of the component.
Use `position` if you need to control size state by yourself.

see, following example.

``` javascript
<Rnd
  size={{ width: this.state.width,  height: this.state.height }}
  position={{ x: this.state.x, y: this.state.y }}
  onDragStop={(e, d) => { this.setState({ x: d.x, y: d.y }) }}
  onResize={(e, direction, ref, delta, position) => {
    this.setState({
      width: ref.offsetWidth,
      height: ref.offsetHeight,
      ...position,
    });
  }}
>
  001
</Rnd>
```

#### `className?: string;`

The `className` property is used to set the custom `className` of the component.

#### `style?: { [key: string]: string };`

The `style` property is used to set the custom `style` of the component.

#### `minWidth?: number | string;`

The `minWidth` property is used to set the minimum width of the component.
For example, you can set `300`, `'300px'`, `50%`.

#### `minHeight?: number | string;`

The `minHeight` property is used to set the minimum height of the component.
For example, you can set `300`, `'300px'`, `50%`.

#### `maxWidth?: number | string;`

The `maxWidth` property is used to set the maximum width of the component.
For example, you can set `300`, `'300px'`, `50%`.

#### `maxHeight?: number | string`;

The `maxHeight` property is used to set the maximum height of the component.
For example, you can set `300`, `'300px'`, `50%`.

#### `resizeGrid?: [number, number];`

The `resizeGrid` property is used to specify the increments that resizing should snap to. Defaults to `[1, 1]`.

#### `dragGrid?: [number, number];`

The `dragGrid` property is used to specify the increments that moving should snap to. Defaults to `[1, 1]`.

#### `lockAspectRatio?: boolean | number;`

The `lockAspectRatio` property is used to lock aspect ratio.
Set to `true` to lock the aspect ratio based on the initial size.
Set to a numeric value to lock a specific aspect ratio (such as `16/9`).
If set to numeric, make sure to set initial height/width to values with correct aspect ratio.
If omitted, set `false`.

#### `lockAspectRatioExtraWidth?: number;`

The `lockAspectRatioExtraWidth` property enables a resizable component to maintain an aspect ratio plus extra width.
For instance, a video could be displayed 16:9 with a 50px side bar.
If omitted, set `0`.

#### `scale?: number;`

Specifies the scale of the canvas you are dragging or resizing this element on. This allows
you to, for example, get the correct drag / resize deltas while you are zoomed in or out via
a transform or matrix in the parent of this element.
If omitted, set `1`.

#### `lockAspectRatioExtraHeight?: number;`

The `lockAspectRatioExtraHeight` property enables a resizable component to maintain an aspect ratio plus extra height.
For instance, a video could be displayed 16:9 with a 50px header bar.
If omitted, set `0`.

#### `dragHandleClassName?: string;`

Specifies a selector to be used as the handle that initiates drag.
Example: `handle`.

#### `resizeHandleStyles?: HandleStyles;`

The `resizeHandleStyles` property is used to override the style of one or more resize handles.
Only the axis you specify will have its handle style replaced.
If you specify a value for `right` it will completely replace the styles for the `right` resize handle,
but other handle will still use the default styles.

``` javascript

export type HandleStyles = {
  bottom?: React.CSSProperties,
  bottomLeft?: React.CSSProperties,
  bottomRight?: React.CSSProperties,
  left?: React.CSSProperties,
  right?: React.CSSProperties,
  top?: React.CSSProperties,

  topRight?: React.CSSProperties
}
```

``` javascript
type HandleClasses = {
  bottom?: string;
  bottomLeft?: string;
  bottomRight?: string;
  left?: string;
  right?: string;
  top?: string;
  topLeft?: string;
  topRight?: string;
}
```

#### `resizeHandleComponent?`: HandleCompoent;`

The `resizeHandleComponent` allows you to pass a custom React component as the resize handle.

``` javascript
type HandleComponent = {
  top?: React.ReactElement<any>;
  right?: React.ReactElement<any>;
  bottom?: React.ReactElement<any>;
  left?: React.ReactElement<any>;
  topRight?: React.ReactElement<any>;
  bottomRight?: React.ReactElement<any>;
  bottomLeft?: React.ReactElement<any>;
  topLeft?: React.ReactElement<any>;
}
```

#### `resizeHandleWrapperClass?: string;`

The `resizeHandleWrapperClass` property is used to set css class name of resize handle wrapper(`span`) element.

#### `resizeHandleWrapperStyle?: Style;`

The `resizeHandleWrapperStyle` property is used to set css class name of resize handle wrapper(`span`) element.

#### `enableResizing?: ?Enable;`

The `enableResizing` property is used to set the resizable permission of the component.

The permission of `top`, `right`, `bottom`, `left`, `topRight`, `bottomRight`, `bottomLeft`, `topLeft` direction resizing.
If omitted, all resizer are enabled.
If you want to permit only right direction resizing, set `{ top:false, right:true, bottom:false, left:false, topRight:false, bottomRight:false, bottomLeft:false, topLeft:false }`.

``` javascript
export type Enable = {
  bottom?: boolean;
  bottomLeft?: boolean;
  bottomRight?: boolean;
  left?: boolean;
  right?: boolean;
  top?: boolean;
  topLeft?: boolean;
  topRight?: boolean;
} | boolean
```

#### `disableDragging?: boolean;`

The `disableDragging` property disables dragging completely.

#### `cancel?: string;`

The `cancel` property disables specifies a selector to be used to prevent drag initialization (e.g. `.body`).

#### `dragAxis?: 'x' | 'y' | 'both' | 'none'`

The direction of allowed movement (dragging) allowed ('x','y','both','none').

#### `bounds?: string; | Element`

Specifies movement boundaries. Accepted values:
 - `parent` restricts movement within the node's offsetParent
    (nearest node with position relative or absolute)
 - `window`, `body`, Selector like `.fooClassName` or
 - `Element`.


#### `enableUserSelectHack?: boolean;`

By default, we add 'user-select:none' attributes to the document body    
to prevent ugly text selection during drag. If this is causing problems    
for your app, set this to `false`.    

#### `scale?: number;`

Specifies the scale of the canvas your are resizing and dragging this element on. This allows
you to, for example, get the correct resize and drag deltas while you are zoomed in or out via
a transform or matrix in the parent of this element.
If omitted, set `1`.

## Callback

#### `onResizeStart?: RndResizeStartCallback;`

`RndResizeStartCallback` type is below.
