This is a web-only guide for setting up Tailwind CSS and Shadcn UI in an Expo Router v3 project.

Install dependencies:

yarn add tailwindcss postcss autoprefixer

Create a tailwind.config.js file:

/** @type {import('tailwindcss').Config} */
module.exports = {
  content: ["./src/app/**/*.{ts,tsx}", "./src/components/**/*.{ts,tsx}"],
  // Not required but I recommend disabling hover effects on touch devices.
  future: {
    hoverOnlyWhenSupported: true,
  },
};

Add a postcss.config.js config file:

module.exports = {
  plugins: {
    autoprefixer: {},
    tailwindcss: {},
  },
};

Create a global CSS file at src/global.css:

@tailwind base;
@tailwind components;
@tailwind utilities;

Import the global CSS file in your root layout src/app/_layout.tsx:

import "../global.css";

Run the shadcn-ui init command to setup your project:

npx shadcn-ui@latest init

You will be asked a few questions to configure components.json:

Would you like to use TypeScript (recommended)? no / yes
Which style would you like to use? › Default
Which color would you like to use as base color? › Slate
Where is your global CSS file? › src/global.css
Do you want to use CSS variables for colors? › no / yes
Where is your tailwind.config.js located? › tailwind.config.js
Configure the import alias for components: › ~/components
Configure the import alias for utils: › ~/lib/utils
Are you using React Server Components? › no

Now you can install and add components to your project:

npx shadcn-ui@latest add button

The command above will add the Button component to your project. You can then import it like this:

import { Button } from "@/components/ui/button";

export default function Home() {
  return (
    <div>
      <Button>Click me</Button>
    </div>
  );
}

Reminder: Shadcn UI does not work on native, so you'll need to ensure you don't load any Shadcn UI components on native. You can use the Platform module to do this. Learn more: Platform-specific modules.
