Installation

npm install --save react-native-drawer

Usage

import Drawer from 'react-native-drawer'

class Application extends Component {  
  closeControlPanel = () => {
    this._drawer.close()
  };
  openControlPanel = () => {
    this._drawer.open()
  };
  render () {
    return (
      <Drawer
        ref={(ref) => this._drawer = ref}
        content={<ControlPanel />}
        >
        <MainView />
      </Drawer>
    )
  }
})

Examples

//Parallax Effect (slack style)
<Drawer
  type="static"
  content={<ControlPanel />}
  openDrawerOffset={100}
  styles={drawerStyles}
  tweenHandler={Drawer.tweenPresets.parallax}
  >
    <Main />
</Drawer>

//Material Design Style Drawer
<Drawer
  type="overlay"
  content={<ControlPanel />}
  tapToClose={true}
  openDrawerOffset={0.2} // 20% gap on the right side of drawer
  panCloseMask={0.2}
  closedDrawerOffset={-3}
  styles={drawerStyles}
  tweenHandler={(ratio) => ({
    main: { opacity:(2-ratio)/2 }
  })}
  >
    <Main />
</Drawer>

const drawerStyles = {
  drawer: { shadowColor: '#000000', shadowOpacity: 0.8, shadowRadius: 3},
  main: {paddingLeft: 3},
}

Props

This module supports a wide range of drawer styles, and hence has a lot of props.

Important

• content (React.Component) null - Menu component
• type (String: displace:overlay:static) displace- Type of drawer.
• open (Boolean) null - If true will trigger drawer open, if false will trigger close.
• openDrawerOffset (Number|Function) 0 - Can either be a integer (pixel value) or decimal (ratio of screen width). Defines the right hand margin when the drawer is open. Or, can be function which returns offset: (viewport) => viewport.width - 200
• closedDrawerOffset (Number|Function) 0 - Same as openDrawerOffset, except defines left hand margin when drawer is closed.
• disabled (Boolean) false - If true the drawer can not be opened and will not respond to pans.
• styles (Object) null - Styles for the drawer, main, drawerOverlay and mainOverlay container Views.

Animation / Tween

Note: In the future animations with use Animated, and the api will change.

• tweenHandler (Function) null - Takes in the pan ratio (decimal 0 to 1) that represents the tween percent. Returns and object of native props to be set on the constituent views { drawer: {/native props/}, main: {/native props/}, mainOverlay: {/native props/} }
• tweenDuration (Integer) 250 - The duration of the open/close animation.
• tweenEasing (String) linear - A easing type supported by tween-functions

Event Handlers

• onOpen (Function) - Will be called immediately after the drawer has entered the open state.
• onOpenStart (Function) callback fired at the start of an open animation.
• onClose (Function) - Will be called immediately after the drawer has entered the closed state.
• onCloseStart (Function) callback fired at the start of a close animation.

Gestures

• captureGestures (oneOf(true, false, 'open', 'closed')) open - If true, will capture all gestures inside of the pan mask. If 'open' will only capture when drawer is open.
• acceptDoubleTap (Boolean) false - Toggle drawer when double tap occurs within pan mask?
• acceptTap (Boolean) false - Toggle drawer when any tap occurs within pan mask?
• acceptPan (Boolean) true - Allow for drawer pan (on touch drag). Set to false to effectively disable the drawer while still allowing programmatic control.
• tapToClose (Boolean) false - Same as acceptTap, except only for close.
• negotiatePan (Boolean) false - If true, attempts to handle only horizontal swipes, making it play well with a child ScrollView.

Additional Configurations

• panThreshold (Number) .25 - Ratio of screen width that must be travelled to trigger a drawer open/close.
• panOpenMask (Number) null - Ratio of screen width that is valid for the start of a pan open action. If null -> defaults to max(.05, closedDrawerOffset).
• panCloseMask (Number) null - Ratio of screen width that is valid for the start of a pan close action. If null -> defaults to max(.05, openDrawerOffset).
• initializeOpen (Boolean) false - Initialize with drawer open?
• side (String left|right) left - which side the drawer should be on.
• useInteractionManager (Boolean) false - if true will run InteractionManager for open/close animations.
• elevation (Number) 0 - (Android-only) Sets the elevation of the drawer using Android's underlying elevation API

Tween Handler

You can achieve pretty much any animation you want using the tween handler with the transformMatrix property. E.G.

tweenHandler={(ratio) => {
  var r0 = -ratio/6
  var r1 = 1-ratio/6
  var t = [
             r1,  r0,  0,  0,
             -r0, r1,  0,  0,
             0,   0,   1,  0,
             0,   0,   0,  1,
          ]
  return {
    main: {
      style: {
        transformMatrix: t,
        opacity: 1 - ratio/2,
      },
    }
  }
}}

Will result in a skewed fade out animation.

Opening & Closing the Drawer Programmatically

Three options:

1. Use the open prop (controlled mode):

   <Drawer
     open={true}
   

2. Using the Drawer Ref:

   // assuming ref is set up on the drawer as (ref) => this._drawer = ref
   onPress={() => {this._drawer.open()}}
   

3. Using Context

   contextTypes = {drawer: React.PropTypes.object}
   // later...
   this.context.drawer.open()
   

Demo

• git clone https://github.com/rt2zz/react-native-drawer.git
• cd react-native-drawer/examples/RNDrawerDemo && npm install
• iOS
  • Open ``./examples/RNDrawerDemo/RNDrawerDemo.xcodeproject` in xcode
  • command+r (in xcode)
• Android
  • Run android simulator / plug in your android device
  • Run react-native run-android in terminal
