Resizable and draggable component for React.

See demo: http://bokuweb.github.io/react-rnd/

npm i react-rnd

<Rnd
  ref={c => { this.rnd = c; }}
  initial={{
    x: window.innerWidth / 2 - 200,
    y: window.innerHeight / 2 - 80,
    width: 400,
    height: 160,
  }}
  style={style}
  minWidth={300}
  minHeight={160}
  maxWidth={800}
  maxHeight={300}
  bounds={'parent'}
>
  <span className="box">
    resize and drag me!!
  </span>
</Rnd>

The width and height property is used to set the size of a component.
The x and y property is used to set the initial position of the component.

The minWidth property is used to set the minimum width of a component.

The minHeight property is used to set the minimum height of a component.

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

The maxheight property is used to set the maximum height of a component.

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

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

The resizerHandleStyle 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.

The isResizable 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 }.

Calls when resizable component clicked.

Calls when resizable component touched.

Calls when resizable component double clicked.

Calls when resizable component resize starts. Calls back with (direction: string, styleSize: object, clientSize: object, event: object)

• direction: top, right, bottom, left, topRight, bottomRight, bottomLeft, and topLeft.
• styleSize: { width, height }
  • this argument is {width, height} of getComputedStyle.
• clientSize: { width, height }
  • this argument is clientWidth and clientHeight.
• event: mouse down event

Calls when resizable component resize. Calls back with (direction: string, styleSize: object, clientSize: object, delta: object, newPos: object)

• direction: top, right, bottom, left, topRight, bottomRight, bottomLeft, and topLeft.
• styleSize: { width, height }
  • this argument is {width, height} of getComputedStyle.
• clientSize: { width, height }
  • this argument is clientWidth and clientHeight.
• delta: { width, height }
  • this delta width and height by resize.
• newPos: { x, y }
  • new position of the element.

For example, when <Resizable width={100} height={200} style={{ padding: '20px'}} onResize={...} /> mounted and resize 'right' 20px, this callback is called with ('right', { width: 120, height: 200 }, { width: 160, height: 240 }, {width: 20, height: 0})

Calls back with (direction: string, styleSize: object, clientSize: object, delta: object)

• direction: top, right, bottom, left, topRight, bottomRight, bottomLeft, and topLeft.
• styleSize: { width, height }
  • this argument is {width, height} of getComputedStyle.
• clientSize: { width, height }
  • this argument is clientWidth and clientHeight.
• delta: { width, height }
  • this delta width and height by resize.

For example, when <Resizable width={100} height={200} style={{ padding: '20px'}} onResize={...} /> mounted and resize 'right' 20px, this callback is called with ('right', { width: 120, height: 200 }, { width: 160, height: 240 }, {width: 20, height: 0}, {x: 20, y: 0})

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

The lockAspectRatio property is used to lock aspect ratio. If ommited, set false.

Callback called on dragging start.

Callback called on resizing.
onDrag called with the following parameters:

(
 event: Event,
 ui:{
      deltaX: number, deltaY: number,
      node: Node
      position:
      {
        left: number, top: number
      }
   }
)

Callback called on dragging stop. onDragStop called with the following parameters:

(
 event: Event,
 ui:{
      deltaX: number, deltaY: number,
      node: Node
      position:
      {
        left: number, top: number
      }
   }
)

Specifies movement boundaries. Accepted values:

• parent restricts movement within the node's offsetParent (nearest node with position relative or absolute), or
• An object with left, top, right, and bottom properties. These indicate how far in each direction the draggable can be moved.

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

The zIndex property is used to set the zindex of a component.

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

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

Update component size. grid ,max/minWidth, max/minHeight props is ignored, when this method called.

• for example

class YourComponent extends Component {

  ...
  
  update() {
    this.rnd.updateSize({ width: 200, height: 300 });
  }
  
  render() {
    return (
      <Rnd ref={c => { this.rnd = c; }}>
        example
      </Rnd>
    );
  }

  ...
}

Update component size. grid bounds props is ignored, when this method called.

• for example

class YourComponent extends Component {

  ...
  
  update() {
    this.rnd.updatePosition({ x: 200, y: 300 });
  }
  
  render() {
    return (
      <Rnd ref={c => { this.rnd = c; }}>
        example
      </Rnd>
    );
  }

  ...
}
