React native drawer, configurable to achieve material design style, slack style, parallax, and more. Works in both iOS and Android.

Android: Android support has been added in v1.3.0!

Installation

npm install react-native-drawer

Usage

var Drawer = require('react-native-drawer')

var Application = React.createClass({
  closeControlPanel: function(){
    this.refs.drawer.close()
  },
  openControlPanel: function(){
    this.refs.drawer.open()
  },
  render: function() {
    return (
      <Drawer
        ref="drawer"
        content={<ControlPanel />}
        >
        <MainView />
      </Drawer>
    )
  }
})

Examples

Simple

//Parallax Effect (slack style)
<Drawer
  type="static"
  content={<ControlPanel />}
  openDrawerOffset={100}
  styles={{main: {shadowColor: "#000000", shadowOpacity: 0.4, shadowRadius: 3}}}
  tweenHandler={Drawer.tweenPresets.parallax}
  >
    <Main />
</Drawer>

//Material Design Style Drawer
<Drawer
  type="overlay"
  openDrawerOffset={50} //50px gap on the right side of drawer
  panCloseMask={1} //can close with right to left swipe anywhere on screen
  styles={{
    drawer: {
      shadowColor: "#000000",
      shadowOpacity: 0.8,
      shadowRadius: 0,
    }
  }}
  tweenHandler={(ratio) => {
    return {
      drawer: { shadowRadius: Math.min(ratio*5*5, 5) },
      main: { opacity:(2-ratio)/2 },
    }
  }}
  content={<ControlPanel />}
  >
    <Main />
</Drawer>

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.
openDrawerOffset (Number) 0 - Can either be a integer (pixel value) or decimal (ratio of screen width). Defines the right hand margin when the drawer is open.
closedDrawerOffset (Number) 0 - Same as openDrawerOffset, except defines left hand margin when drawer is closed.
tapToClose (Boolean) false - When the drawer is open, whether a tap should close it.
disabled (Boolean) false - If true the drawer can not be opened and will not respond to pans.

Animation / Tween

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/} }
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.
onClose (Function) - Will be called immediately after the drawer has entered the closed state.

Gestures

captureGestures (Boolean) false - If true, will capture all gestures inside of the pan mask. Meaning child buttons and scroll views will not trigger.
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.

Additional Configurations

openDrawerThreshold (Number) .25 - Ratio of screen width that must be travelled to trigger a drawer open/close
panOpenMask (Number) .05 - Ratio of screen width that is valid for the start of a pan open action. Make this number small if you need pans to propagate to children.
panCloseMask (Number) .25 - Ratio of screen width that is valid for the start of a pan close action. Make this number small if you need pans to propagate to children.
relativeDrag (Boolean) true - true -> open/close calculation based on pan dx : false -> calculation based on absolute pan position (i.e. touch location)
panStartCompensation (Boolean) false - Should the drawer catch up to the finger drag position?
initializeOpen (Boolean) false - Initialize with drawer open?
side (String left|right) left - which side the drawer should be on.

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.

warning: Frame rate, and perceived smoothness will vary based on the complexity and speed of the animation. It will likely require some tweaking and compromise to get the animation just right.
