How to install React Native Reanimated and Gesture Handler

This article guides you through the process of initializing a React Native (with and without Expo) project using Reanimated and React Native Gesture Handler fully configured.

Don't worry, it will be easier than you might think.

Since we're going to use Expo, make sure to have it already installed. If you don't have the Expo CLI installed, just run the following command:

Ensure Expo is Installed:

Before we start, make sure you have Expo installed. If not, run the following command:

npm install --global expo-cli

Now, let's dive in:

npx create-expo-app YOUR-PROJECT-NAME -t expo-template-blank-typescript

If everything is successful, you'll see the default App.tsx file with a basic component.

import { StatusBar } from 'expo-status-bar';
import React from 'react';
import { StyleSheet, Text, View } from 'react-native';

export default function App() {
  return (
    <View style={styles.container}>
      <Text>Open up App.tsx to start working on your app!</Text>
      <StatusBar style="auto" />
    </View>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: '#fff',
    alignItems: 'center',
    justifyContent: 'center',
  },
});

Installing Reanimated

To install Reanimated, run:

npx expo install react-native-reanimated

However, simply installing the package is not enough. If you try to use Reanimated methods in the App component without configuring Babel, your app will crash. To fix this, add the Reanimated babel plugin in the babel.config.js file:

module.exports = function(api) {
  api.cache(true);
  return {
    presets: ['babel-preset-expo'],
    plugins: ['react-native-reanimated/plugin']
  };
};

Now, you might be wondering how to use Reanimated. I've created a series on this topic. Click here if you're interested.

Installing React Native Gesture Handler

For React Native Gesture Handler, the process is similar. Run:

npx expo install react-native-gesture-handler

To complete the installation, ensure that all components are wrapped with GestureHandlerRootView:

...
import { GestureHandlerRootView } from 'react-native-gesture-handler';

export default function App() {
  return (
    <GestureHandlerRootView style={{flex: 1}}>
      <View style={styles.container}>
        <Text>Open up App.tsx to start working on your app!</Text>
        <StatusBar style="auto" />
      </View>
    </GestureHandlerRootView>
  );
}

...

Using React Native CLI

For React Native CLI, the process is almost identical. Replace a few commands:

Project Setup

Instead of expo init, run:

npx react-native init AwesomeTSProject --template react-native-template-typescript

Packages Installation

Replace:

npx expo install react-native-reanimated react-native-gesture-handler

with yarn:

yarn add react-native-reanimated react-native-gesture-handler

or if you're using npm:

npm install react-native-reanimated react-native-gesture-handler

Conclusions

In conclusion, setting up a React Native project with Expo, Reanimated, and React Native Gesture Handler is a straightforward process. Ensure you follow the steps outlined above, and you'll be ready to explore the powerful capabilities these libraries offer in enhancing your React Native applications. Happy coding!
