Usage

Installation

$ yarn add react-native-magic-move

Wrap your app with the <MagicMove.Provider> context.

import * as MagicMove from 'react-native-magic-move';

const App = () => (
  <MagicMove.Provider>
    {...}
  </MagicMove.Provider>
);

Add the <MagicMove.{View|Image|Text}> component to your views. Whenever the Magic Move component is mounted while another Magic Move component with the same id is already mounted, then a magic transition between the components is performed.

import * as MagicMove from 'react-native-magic-move';

const Scene1 = () => (
  <MagicMove.Scene>
    <MagicMove.View id="logo" style={{
        width: 100,
        height: 100,
        backgroundColor: "green",
        borderRadius: 50
      }} />
  </MagicMove.Scene>
);

const Scene2 = () => (
  <MagicMove.Scene>
    <MagicMove.View id="logo" style={{
        width: 200,
        height: 200,
        backgroundColor: "purple",
        borderRadius: 0
      }} />
  </MagicMove.Scene>
);

Documentation

Components

The following magic-move components are supported out of the box.

• MagicMove.View
• MagicMove.Text
• MagicMove.Image

You can also create your own custom MagicMove components.

MyCustomComponent = MagicMove.createMagicMoveComponent(MyCustomComponent);

Props

Property	Type	Default	Description
id	string	(required)	Unique id of the magic-move instance
duration	number	400	Length of the animation (milliseconds)
delay	number	0	Amount of msec to wait before starting the animation
easing	function	Easing.inOut(Easing.ease)	Easing function to define the curve
transition	function	(default transition)	Transition effect
useNativeDriver	boolean	false	Enables the native-driver
keepHidden	boolean	false	Keeps the source component hidden after the animation has completed
debug	boolean	false	Enables debug-mode to analyze animations

Scenes

Use <MagicMove.Scene> to mark the start of a scene within the rendering hierarchy. This is important so that Magic Move can correctly assess the destination-position of an animation. MagicMove.Scene is implemented using a regular View and supports all its properties.

Transitions

Transitions are an experimental feature for which the API may change. At the moment only two transitions are supported default and flip.

To use the experimental flip transition, use:

const flipTransition = MagicMove.Transition.flip({
  x: true,  // set to true for a flip over the horizontal axis
  y: false, // set to true for a flip over the vertival axis
  step: 0.5 // [0..1]
});

<MagicMove.View transition={flipTransition} .../>

Examples

Example with scene transitions using react-native-router-flux.

import React from "react";
import { View, TouchableOpacity } from "react-native";
import { Router, Stack, Scene, Actions } from "react-native-router-flux";
import * as MagicMove from "react-native-magic-move";

const Scene1 = () => (
  <MagicMove.Scene>
    <TouchableOpacity onPress={() => Actions.scene2()}>
      <MagicMove.View id="myView" style={{
        alignSelf: "center",
        width: 100,
        height: 100,
        backgroundColor: "green",
        borderRadius: 20
      }} />
    </TouchableOpacity>
  </MagicMove.Scene>
);

const Scene2 = () => (
  <MagicMove.Scene>
    <MagicMove.View id="myView" style={{
      height: 300,
      backgroundColor: "purple"
    }} />
  </MagicMove.Scene>
);

const App = () => (
  <MagicMove.Provider>
    <Router>
      <Stack key="root">
        <Scene key="scene1" component={Scene1} />
        <Scene key="scene2" component={Scene2} />
      </Stack>
    </Router>
  </MagicMove.Provider>
);

See examples/src for more code examples.

Disclaimer 🐰🎩

Magic-move creates the illusion of transitioning/morphing components from one scene to another. It however doesn't actually move components to different scenes. As with real magic tricks, there will be situations where the illusion will not work for you. And as with magic tricks, you may need to "set the stage" (e.g. change some stuff in your app) to create the transition that you want. So now that you've received this reality check ✅, go forth and create some bad-ass illusions. Drop me a note of the cool stuff you've built with it. Grand wizard, IjzerenHein
