Installation

1 Install react-native-tailwindcss via npm

# Using npm
npm install react-native-tailwindcss

# Using Yarn
yarn add react-native-tailwindcss

2 Create your Tailwind config file (optional)

If you’d like to customize your Tailwind installation, you can generate a config file for your project using the Tailwind CLI utility included when you install the react-native-tailwindcss npm package:

npx RNtailwindcss

This will create the full fledged tailwind.config.js file at the root of your project. This will output the full config file adjusted for react-native-tailwindcss:

// tailwind.config.js
