# React Native CLI

## 1. Create the project

```bash
npx react-native init AwesomeProject
cd AwesomeProject
```

You will need to install `nativewind` and it's peer dependency `tailwindcss`.

```bash
yarn add nativewind
yarn add --dev tailwindcss
```

## 2. Setup Tailwind CSS

:::caution

Do not set your content to `./**/*`! This will cause Tailwind CLI to scan every file in your `node_modules`.
For the fastest builds, be as specific as possible.

:::

Run `npx tailwindcss init` to create a `tailwind.config.js` file

Add the paths to all of your component files in your tailwind.config.js file.

```diff
// tailwind.config.js
+ const nativewind = require("nativewind/tailwind")

module.exports = {
- content: [],
+ content: ["./App.{js,jsx,ts,tsx}", "./screens/**/*.{js,jsx,ts,tsx}"],
  theme: {
    extend: {},
  },
  plugins: [],
+ presets: [nativewind]
}
```

## 3. Add the Babel preset

Modify your `babel.config.js`

```diff
// babel.config.js
module.exports = {
- presets: ['module:metro-react-native-babel-preset'],
+ presets: ["module:metro-react-native-babel-preset", "nativewind/babel"],
};
```

## 4. Modify the Metro config

```diff
/**
 * Metro configuration for React Native
 * https://github.com/facebook/react-native
 *
 * @format
 */
+ const withNativewind = require("nativewind/metro")

module.exports = withNativewind({
  transformer: {
    getTransformOptions: async () => ({
      transform: {
        experimentalImportSupport: false,
        inlineRequires: true,
      },
    }),
  },
});
```

## Thats it 🎉

Start writing code!
