Custom animatable stack design with react router native

Custom animatable stack design with react router native

react-router-native-animate-stack

A latest React version react router native animate stack.

purpose of this component

React Router Native v5 with your desired customization transition style! It's design with Animated.View

This package only useable with React Router Native. Use it like a React router native's Switch

Installation

Install react-router-native and this package:

npm install react-router-native react-router-native-animate-stack --save

OR

yarn add react-router-native react-router-native-animate-stack

Usage

Here's a simple working example of using it.

// When no customization, it is just like a stack
<AnimatedStack
    swipeCancelSpeed={50}
    swipeable={true}>
    <Route exact path='/'>
        <Home />
    </Route>
    <Route path='/about'>
        <About />
    </Route>
    <Route path='/topics' component={Topics} />
</AnimatedStack>

This is what the above code looks like running on iOS simulator:

Default Behaviour

The stack component will trigger gesture swipe forward and backward when passing swipeable true.

If you are familiar with Switch, you will know how to use this.

Customizing Animation your desire animation style

onMountAnimate

when the component mounted, you can defined how you going to animate

onTransitionAnimate

when the component swap between 2 screen, you can animating the view!

activedViewStyleHandler

Enter animation style is the ViewStyle for Enter Screen, which is acive screen

deactivedViewStyleHandler

Exit animation style is the ViewStyle for Exit Screen, which is deactive screen

Below example you will be more clear:


const App = () => {
  const enterAnimKit = new Animated.Value(0);
  const exitAnimKit = new Animated.Value(0);
  const width = useWindowDimensions().width;
  return (
    <SafeAreaView>
      <NativeRouter>
        <View style={styles.container}>
          <Navigator />
          <AnimatedStack
            swipeCancelSpeed={50}
            swipeable={true}
            onMountAnimate={() => {
              Animated.timing(enterAnimKit, {
                toValue: 1,
                duration: 100
              }).start();
            }}
            onTransitionAnimate={({ location, action, isNestedRoute }) => {
              if (isNestedRoute) return;
              // Enter and exit or one only
              enterAnimKit.setValue(0);
              exitAnimKit.setValue(0);

              Animated.timing(enterAnimKit, {
                toValue: 1,
                duration: 500,
                delay: 200
              }).start();

              Animated.timing(exitAnimKit, {
                toValue: 1,
                duration: 500
              }).start();
            }}
            activedViewStyleHandler={({ location, action, isNestedRoute }) => {
              return {
                transform: [
                  {
                    translateX: enterAnimKit.interpolate({
                      inputRange: [0, 1],
                      outputRange: [width, 0]
                    })
                  }
                ]
              };
            }}
            deactivedViewStyleHandler={({ location, action, isNestedRoute }) => {
              return {
                transform: [
                  {
                    translateX: exitAnimKit.interpolate({
                      inputRange: [0, 1],
                      outputRange: [0, -width]
                    })
                  }
                ]
              };
            }}
          >
            <Route exact path='/'>
              <Home />
            </Route>
            <Route path='/about'>
              <About />
            </Route>
            <Route path='/topics' component={Topics} />
          </AnimatedStack>
        </View>
      </NativeRouter>
    </SafeAreaView>
  );
};

With this code given, the transition will be shown as below

Customize Transiction Animation

Reason of created this

React Router Native still a popular routing engine which native, clean(no other UI kit dependencies) and powerful for routing but no animation.

Now added on animate stack, you can animate the view on run time, changing the animation style on runtime!

React router for routing, let the drawer, menu bar, tab bar and other fancy UI kits bar for other Ui Library control without any breakage.

Design for latest React Version.

This package is using getDerivedStateFromProps function which going to replace componentWillReceiveProps
