Answer 1

1. make sure you installed the needed the needed dependencies:

   npm install nativewind react-native-reanimated

   if you're using expo:

   npm install --save-dev babel-plugin-tailwindcss-react-native

2. config your babel.config.js, your babel.config.js should look like this:

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

3. now you also need to config tailwind.config.js for the project, if you dont have it then:

   npx tailwindcss init

   then change the content to this:

/** @type {import('tailwindcss').Config} */
module.exports = {
  content: [
    "./app/**/*.{js,jsx,ts,tsx}",
    "./components/**/*.{js,jsx,ts,tsx}",
  ],
...
}

4. import this in your root _layout : import 'react-native-reanimated';

5. now after making sure you've configured everything right this is an example of how you define your own Animations in the tailwind.config.js:

module.exports = {
  theme: {
    extend: {
      animation: {
        'fade-in': 'fadeIn 1s ease-in-out',
      },
      keyframes: {
        fadeIn: {
          '0%': { opacity: 0 },
          '100%': { opacity: 1 },
        },
      },
    },
  },
};

then use it like this:

<View className="animate-fade-in">
  <Text>Hello, world!</Text>
</View>
