Get started

Pose is a declarative motion system that combines the simplicity of CSS syntax with the power and flexibility of JavaScript animations and interactions.

In this series of tutorials, we’ll learn how to use Pose for React Native. We’ll gradually introduce each of its features, starting with this simple opacity animation:


Install Pose for React Native in your React Native project:


npm install react-native-pose


yarn add react-native-pose

The “Hello World” animation

In Pose for React Native, we create animated components by importing posed from react-native-posed:

import posed from 'react-native-pose';

posed can create animated versions of any component, but it has built-in support for View, Text, Image, and ScrollView:

const Box = posed.View();

We can pass a a configuration object to the posed component that defines visual states, or “poses”, that our component can be in:

const Box = posed.View({
  visible: { opacity: 1 },
  hidden: { opacity: 0 }

This Box component can be animated between 'hidden' and 'visible' poses by passing it a pose property on render:

export default ({ isVisible }) => (
  <Box style={} pose={isVisible ? 'visible' : 'hidden'} />

And that’s it! By switching isVisible, your Box component will animate in and out.

But wait, where did we define the animation?

Short answer: we didn’t.

More helpful answer: By default, Pose doesn’t require you to explicitly define the animations used to transition between two states.

Instead, it automatically selects a React Animated animation based on the property being animated.

These animations have been designed to create snappy and playful interfaces. Physical motion uses spring to maintain velocity between animations, whereas properties like opacity use a tween.

However, there will always be situations where we need greater control over our animations. For that, we can define custom transitions.
