🚀 react-native-boost

A powerful Babel plugin that automatically optimizes React Native apps through static source code analysis. It replaces standard React Native components with their native counterparts where possible, leading to significant performance improvements.

• ⚡ Automatic performance optimization through source code analysis
• 🔒 Safe optimizations that don't break your app
• 🎯 Virtually zero runtime overhead
• 📱 Cross-platform compatible
• 🧪 Works seamlessly with Expo
• 🎨 Configurable optimization strategies

Documentation

Installation

Install the package using your favorite package manager. Please do not install the package as a dev dependency. While the Babel plugin itself would work as a dev dependency, it relies on importing the runtime library (react-native-boost/runtime) into your code, which requires the package to be installed as a regular dependency. Read more here.

npm install react-native-boost
# or
yarn add react-native-boost

Then, add the plugin to your Babel configuration (babel.config.js):

module.exports = {
  plugins: ['react-native-boost/plugin'],
};

If you're using Expo and don't see the babel.config.js file, run the following command to create it:

npx expo customize babel.config.js

If you're using Unistyles or Nativewind, refer to additional required setup instructions in the documentation.

Finally, restart your React Native development server and clear the bundler cache:

npm start --clear
# or
yarn start --clear

That's it! No imports in your code, rebuilding, or anything else is required.

Optionally, you can configure the Babel plugin with a few options described in the documentation.

How it works

A short overview of how the plugin works as well as a technical deep dive can be found in the documentation.
