## Install

```sh
$ npm install --save re-resizable
```

## Usage

### Example with `defaultSize`

```javascript
<Resizable
  defaultSize={{
    width:320,
    height:200,
  }}
>
  Sample with default size
</Resizable>
```

### Example with `size`

If you use `size` props, please manage state by yourself.

```javascript
<Resizable
  size={{ width: this.state.width, height: this.state.height }}
  onResizeStop={(e, direction, ref, d) => {
    this.setState({
      width: this.state.width + d.width,
      height: this.state.height + d.height,
    });
  }}
>
  Sample with size
</Resizable>
```

## Props

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

Specifies the `width` and `height` that the dragged item should start at.
For example, you can set `300`, `'300px'`, `50%`.
If both `defaultSize` and `size` omitted, set `'auto'`.

`defaultSize` will be ignored when `size` set.

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

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

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

#### `className?: string;`

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

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

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

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

The `minWidth` property is used to set the minimum width of a resizable component. Defaults to 10px.

It accepts viewport as well as parent relative units. For example, you can set `300`, `50%`, `50vw` or `50vh`.

Same type of values can be applied to `minHeight`, `maxWidth` and `maxHeight`.

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

The `minHeight` property is used to set the minimum height of a resizable component. Defaults to 10px.

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

The `maxWidth` property is used to set the maximum width of a resizable component.

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

The `maxHeight` property is used to set the maximum height of a resizable component.

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

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

#### `snap?: { x?: Array<number>, y?: Array<number> };`

The `snap` property is used to specify absolute pixel values that resizing should snap to. `x` and `y` are both optional, allowing you to only include the axis you want to define. Defaults to `null`.

#### `snapGap?: number`

The `snapGap` property is used to specify the minimum gap required in order to move to the next snapping target. Defaults to `0` which means that snap targets are always used.

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

The `resizeRatio` property is used to set the number of pixels the resizable component scales by compared to the number of pixels the mouse/touch moves. Defaults to `1` (for a 1:1 ratio). The number set is the left side of the ratio, `2` will give a 2:1 ratio.

#### `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`.

#### `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`.

#### `bounds?: ('window' | 'parent' | HTMLElement);`

Specifies resize boundaries.

#### `boundsByDirection?: boolean;`

By default max dimensions based on left and top element position.
Width grow to right side, height grow to bottom side.
Set `true` for detect max dimensions by direction.
For example: enable `boundsByDirection` when resizable component stick on right side of screen and you want resize by left handler;

`false` by default.

#### `handleStyles?: HandleStyles;`

The `handleStyles` 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.

#### `handleClasses?: HandleClassName;`

The `handleClasses` property is used to set the className of one or more resize handles.

#### `handleComponent?: HandleComponent;`

The `handleComponent` property is used to pass a React Component to be rendered as one or more resize handle. For example, this could be used to use an arrow icon as a handle..

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

The `handleWrapperStyle` property is used to override the style of resize handles wrapper.

#### `handleWrapperClass?: string;`

The `handleWrapperClass` property is used to override the className of resize handles wrapper.

#### `enable?: ?Enable;`

The `enable` property is used to set the resizable permission of a resizable 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 }`.

#### `onResizeStart?: ResizeStartCallBack;`

`ResizeStartCallBack` type is below.

```javascript
type ResizeStartCallback = (
  e: SyntheticMouseEvent<HTMLDivElement> | SyntheticTouchEvent<HTMLDivElement>,
  dir: ResizableDirection,
  refToElement: HTMLDivElement,
) => void;
```

Calls when resizable component resize start.

#### `onResize?: ResizeCallback;`

#### `scale?: number`;

The `scale` property is used in the scenario where the resizable element is a descendent of an element using css scaling (e.g. - `transform: scale(0.5)`).

#### `as?: string | React.ComponentType`;

By default the `Resizable` component will render a `div` as a wrapper. The `as` property is used to change the element used.

### Basic

`ResizeCallback` type is below.

```javascript
type ResizeCallback = (
  event: MouseEvent | TouchEvent,
  direction: ResizableDirection,
  refToElement: HTMLDivElement,
  delta: NumberSize,
) => void;
```

Calls when resizable component resizing.

#### `onResizeStop?: ResizeCallback;`

`ResizeCallback` type is below.

```javascript
type ResizeCallback = (
  event: MouseEvent | TouchEvent,
  direction: ResizableDirection,
  refToElement: HTMLDivElement,
  delta: NumberSize,
) => void;
```

Calls when resizable component resize stop.

## Instance API

#### * `updateSize(size: { width: number | string, height: number | string }): void`

Update component size.

`grid`, `snap`, `max/minWidth`, `max/minHeight` props is ignored, when this method called.

- for example

```javascript
class YourComponent extends Component {

  // ...

  update() {
    this.resizable.updateSize({ width: 200, height: 300 });
  }

  render() {
    return (
      <Resizable ref={c => { this.resizable = c; }}>
        example
      </Resizable>
    );
  }

  // ...
}
```
