# react-native-animatable Declarative transitions and animations for React Native [![Tests](https://github.com/oblador/react-native-animatable/actions/workflows/tests.yml/badge.svg)](https://github.com/oblador/react-native-animatable/actions/workflows/tests.yml) [![npm](https://img.shields.io/npm/v/react-native-animatable.svg)](https://npmjs.com/package/react-native-animatable) [![npm](https://img.shields.io/npm/dm/react-native-animatable.svg)](https://npmjs.com/package/react-native-animatable) ## Installation `$ npm install react-native-animatable --save` ## Usage To animate things you must use the `createAnimatableComponent` composer similar to the `Animated.createAnimatedComponent`. The common components `View`, `Text` and `Image` are precomposed and exposed under the `Animatable` namespace. If you have your own component that you wish to animate, simply wrap it with a `Animatable.View` or compose it with: ```js import * as Animatable from 'react-native-animatable'; MyCustomComponent = Animatable.createAnimatableComponent(MyCustomComponent); ``` ### Declarative Usage #### Animations ```html Zoom me up, Scotty ``` #### Looping To make looping animations simply set the `iterationCount` to `infinite`. Most animations except the attention seekers work best when setting `direction` to `alternate`. ```html Up and down you go ❤️ ``` ![Animatable looping demo](https://cloud.githubusercontent.com/assets/378279/10716023/9f4a6670-7b00-11e5-944c-d52a1dcf0884.gif) #### Generic transitions You can create your own simple transitions of a style property of your own choosing. The following example will increase the font size by 5 for every tap – all animated, all declarative! If you don't supply a `duration` property, a spring animation will be used. *Note: If you are using colors, please use `rgba()` syntax.* *Note: Transitions require `StyleSheet.flatten` available in React Native 0.15 or later. If you are running on anything lower, please polyfill as described under imperative usage.* ```html this.setState({fontSize: (this.state.fontSize || 10) + 5 })}> Size me up, Scotty ``` #### Properties *Note: Other properties will be passed down to underlying component.* | Prop | Description | Default | |---|---|---| |**`animation`**|Name of the animation, see below for available animations. |*None*| |**`duration`**|For how long the animation will run (milliseconds). |`1000`| |**`delay`**|Optionally delay animation (milliseconds). |`0`| |**`direction`**|Direction of animation, especially useful for repeating animations. Valid values: `normal`, `reverse`, `alternate`, `alternate-reverse`. |`normal`| |**`easing`**|Timing function for the animation. Valid values: custom function or `linear`, `ease`, `ease-in`, `ease-out`, `ease-in-out`, `ease-in-cubic`, `ease-out-cubic`, `ease-in-out-cubic`, `ease-in-circ`, `ease-out-circ`, `ease-in-out-circ`, `ease-in-expo`, `ease-out-expo`, `ease-in-out-expo`, `ease-in-quad`, `ease-out-quad`, `ease-in-out-quad`, `ease-in-quart`, `ease-out-quart`, `ease-in-out-quart`, `ease-in-quint`, `ease-out-quint`, `ease-in-out-quint`, `ease-in-sine`, `ease-out-sine`, `ease-in-out-sine`, `ease-in-back`, `ease-out-back`, `ease-in-out-back`. |`ease`| |**`iterationCount`**|How many times to run the animation, use `infinite` for looped animations. |`1`| |**`iterationDelay`**|For how long to pause between animation iterations (milliseconds). |`0`| |**`transition`**|What `style` property to transition, for example `opacity`, `rotate` or `fontSize`. Use array for multiple properties. |*None*| |**`onAnimationBegin`**|A function that is called when the animation has been started. |*None*| |**`onAnimationEnd`**|A function that is called when the animation has been completed successfully or cancelled. Function is called with an `endState` argument, refer to `endState.finished` to see if the animation completed or not. |*None*| |**`onTransitionBegin`**|A function that is called when the transition of a style has been started. The function is called with a `property` argument to differentiate between styles. |*None*| |**`onTransitionEnd`**|A function that is called when the transition of a style has been completed successfully or cancelled. The function is called with a `property` argument to differentiate between styles. |*None*| |**`useNativeDriver`**|Whether to use native or JavaScript animation driver. Native driver can help with performance but cannot handle all types of styling. |`false`| |**`isInteraction`**|Whether or not this animation creates an "interaction handle" on the InteractionManager. |`false` if `iterationCount` is less than or equal to one| ### Imperative Usage #### Animations All animations are exposed as functions on Animatable elements, they take an optional `duration` argument. They return a promise that is resolved when animation completes successfully or is cancelled. ```js import * as Animatable from 'react-native-animatable'; class ExampleView extends Component { handleViewRef = ref => this.view = ref; bounce = () => this.view.bounce(800).then(endState => console.log(endState.finished ? 'bounce finished' : 'bounce cancelled')); render() { return ( Bounce me! ); } } ``` To stop any ongoing animations, just invoke `stopAnimation()` on that element. You can also animate imperatively by using the `animate()` function on the element for custom animations, for example: ``` this.view.animate({ 0: { opacity: 0 }, 1: { opacity: 1 } }); ``` #### Generic transitions ##### `transition(fromValues, toValues[[, duration], easing])` Will transition between given styles. If no `duration` or `easing` is passed a spring animation will be used. ##### `transitionTo(toValues[[, duration], easing])` This function will try to determine the current styles and pass it along to `transition()` as `fromValues`. ```js import * as Animatable from 'react-native-animatable'; class ExampleView extends Component { handleTextRef = ref => this.text = ref; render() { return ( this.text.transitionTo({ opacity: 0.2 })}> Fade me! ); } } ``` ## Custom Animations Animations can be referred to by a global name or a definition object. ### Animation Definition Schema An animation definition is a plain object that contains an optional `easing` property, an optional `style` property for static non-animated styles (useful for `perspective`, `backfaceVisibility`, `zIndex` etc) and a list of keyframes. The keyframes are refered to by a number between 0 to 1 or `from` and `to`. Inspect the source in the `definitions` folder to see more in depth examples. A simple fade in animation: ```js const fadeIn = { from: { opacity: 0, }, to: { opacity: 1, }, }; ``` ```html Fade me in ``` Combining multiple styles to create a zoom out animation: ```js const zoomOut = { 0: { opacity: 1, scale: 1, }, 0.5: { opacity: 1, scale: 0.3, }, 1: { opacity: 0, scale: 0, }, }; ``` ```html Zoom me out ``` To make your animations globally available by referring to them by a name, you can register them with `initializeRegistryWithDefinitions`. This function can also be used to replace built in animations in case you want to tweak some value. ```js Animatable.initializeRegistryWithDefinitions({ myFancyAnimation: { from: { ... }, to: { ... }, } }); ``` ## React Europe Talk [![18922912_1935104760082516_4717918248927023870_o](https://user-images.githubusercontent.com/378279/36341201-fd11e80c-13ea-11e8-8585-ab1d0c5ae27d.jpg)](https://www.youtube.com/watch?v=3SITFIGz4xo) The talk __*A Novel Approach to Declarative Animations in React Native*__ from React Europe 2017 about this library and animations/transitions in general is [available on YouTube](https://www.youtube.com/watch?v=3SITFIGz4xo). ## `MakeItRain` example See [`Examples/MakeItRain`](https://github.com/oblador/react-native-animatable/tree/master/Examples/MakeItRain) folder for the example project from the talk.
