  <button @click="toggleMessage">Toggle Message</button>
</div>

<script>
  new Vue({
    el: '#app',
    data: {
      showMessage: true,
      message: 'Hello, Vue!'
    },
    methods: {
      toggleMessage() {
        this.showMessage = !this.showMessage;
      }
    }
  })
</script>
```

Explanation:
- `v-if="showMessage"` conditionally renders the `<h1>` element based on the value of the `showMessage` property.
- `v-else` renders the `<p>` element if the condition is false.
- `@click="toggleMessage"` attaches a click event listener to the button and calls the `toggleMessage` method when clicked.
- `toggleMessage()` toggles the value of the `showMessage` property when the button is clicked.

Libraries play a crucial role in React Native development. They provide pre-built components, utilities, and tools that can be easily integrated into your projects. By using libraries, developers can save time and effort by avoiding reinventing the wheel and focus on building the unique aspects of their application.

## 1. React Navigation

React Navigation is a popular library for handling navigation in React Native applications. It provides a flexible and easy-to-use API for managing navigation stacks, tabs, and drawers. React Navigation supports both iOS and Android platforms and offers various navigation options, such as stack navigation, tab navigation, and drawer navigation.

### Installation and Setup

To install React Navigation, use the following command:

```shell
npm install @react-navigation/native
```

Next, install the required dependencies for your chosen navigation type. For example, to install stack navigation, use the following command:

```shell
npm install @react-navigation/stack
```

To set up React Navigation in your app, you need to create a navigation container and define your navigation structure. Here's an example:

```javascript
import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator } from '@react-navigation/stack';

const Stack = createStackNavigator();

function App() {
  return (
    <NavigationContainer>
      <Stack.Navigator>
        {/* Define your screens here */}
      </Stack.Navigator>
    </NavigationContainer>
  );
}

export default App;
```

### Key Features

- **Stack Navigation**: React Navigation allows you to define a stack of screens, where each screen is pushed onto the stack when navigated to and popped off when navigated back.
- **Tab Navigation**: With React Navigation, you can create a tab-based navigation interface where each tab represents a different screen.
- **Drawer Navigation**: React Navigation supports drawer navigation, allowing you to create a sidebar menu that can be accessed by swiping from the edge of the screen.

### Examples of Usage

Here's an example of how to define stack navigation using React Navigation:

```javascript
import { createStackNavigator } from '@react-navigation/stack';

const Stack = createStackNavigator();

function App() {
  return (
    <Stack.Navigator>
      <Stack.Screen name="Home" component={HomeScreen} />
      <Stack.Screen name="Profile" component={ProfileScreen} />
    </Stack.Navigator>
  );
}
```

In this example, we define two screens: "Home" and "Profile". The `HomeScreen` and `ProfileScreen` components represent the content of each screen.

## 2. React Native Elements

React Native Elements is a UI toolkit that provides ready-to-use components for building user interfaces in React Native applications. It offers a wide range of customizable components, such as buttons, cards, input fields, and more. React Native Elements follows Material Design guidelines and provides a consistent and beautiful UI across different platforms.

### Installation and Setup

To install React Native Elements, use the following command:

```javascript
import { Button, Card } from 'react-native-elements';

function App() {
  return (
    <Card>
      <Card.Title>React Native Elements</Card.Title>
      <Card.Divider />
      <Button title="Click Me" onPress={() => console.log('Button pressed')} />
    </Card>
  );
}
```

### Key Features

- **Ready-to-Use Components**: React Native Elements provides a wide range of pre-built components that can be easily customized to match your app's design.

function App() {
  return (
    <Button
      title="Click Me"
      onPress={() => console.log('Button pressed')}
    />
  );
}
```

In this example, we create a button component with the title "Click Me" and a callback function that logs a message when the button is pressed.

## 3. Redux

Redux is a state management library that helps you manage the state of your React Native applications. It provides a predictable state container and a set of principles for managing state transitions. Redux is widely used in large-scale applications and offers a centralized approach to state management.

### Installation and Setup

To install Redux, use the following command:

```shell
npm install redux react-redux
```

To set up Redux in your app, you need to define your application state, actions, and reducers. Here's a simplified example:

```javascript
// store.js
import { createStore } from 'redux';
import rootReducer from './reducers';

const store = createStore(rootReducer);

export default store;
```

```javascript
// reducers.js
import { combineReducers } from 'redux';

const initialState = {
  counter: 0,
};

function counterReducer(state = initialState, action) {
  switch (action.type) {
    case 'INCREMENT':
      return { ...state, counter: state.counter + 1 };
    case 'DECREMENT':
      return { ...state, counter: state.counter - 1 };
    default:
      return state;
  }
}

const rootReducer = combineReducers({
  counter: counterReducer,
});

export default rootReducer;
```

### Key Concepts

- **Store**: The store holds the application state and provides methods to access and update it. It is created using the `createStore` function from Redux.
- **Actions**: Actions are plain JavaScript objects that represent an intention to change the state. They are dispatched using the `dispatch` method and are handled by reducers.
- **Reducers**: Reducers are pure functions that specify how the application's state changes in response to actions. They take the current state and an action as input and return a new state.

### Examples of Usage

Here's an example of how to use Redux to manage a counter state in your app:

```javascript
import { useSelector, useDispatch } from 'react-redux';

function Counter() {
  const counter = useSelector((state) => state.counter);
  const dispatch = useDispatch();

  const increment = () => {
    dispatch({ type: 'INCREMENT' });
  };

  const decrement = () => {
    dispatch({ type: 'DECREMENT' });
  };

  return (
    <View>
      <Text>Counter: {counter}</Text>
      <Button title="Increment" onPress={increment} />
      <Button title="Decrement" onPress={decrement} />
    </View>
  );
}
```

In this example, we use the `useSelector` hook to access the counter state from the Redux store and the `useDispatch` hook to dispatch actions. The `increment` and `decrement` functions dispatch the corresponding actions when the buttons are pressed.

## 4. Axios

Axios is a popular library for making HTTP requests in JavaScript applications, including React Native. It provides an easy-to-use API for sending HTTP requests and handling responses. Axios supports various features, such as request and response interception, automatic JSON parsing, and more.

### Installation and Setup

To install Axios, use the following command:

```shell
npm install axios
```

To make an HTTP request using Axios, you can use the `axios` function. Here's an example:

```javascript
import axios from 'axios';

function fetchData() {
  axios.get('https://api.example.com/data')
    .then((response) => {
      console.log(response.data);
    })
    .catch((error) => {
      console.error(error);
    });
}
```

### Making API Requests

To send an HTTP GET request, use the `axios.get` method and provide the URL of the API endpoint. You can also pass additional configuration options, such as headers or query parameters.

```javascript
axios.get('https://api.example.com/data', {
  headers: { Authorization: 'Bearer token' },
  params: { limit: 10 },
})
  .then((response) => {
    console.log(response.data);
  })
  .catch((error) => {
    console.error(error);
  });
```

### Handling Responses

Axios provides various methods for handling responses, such as `then` and `catch` for handling successful and error responses, respectively. You can access the response data using the `data` property of the response object.

```javascript
axios.get('https://api.example.com/data')
  .then((response) => {
    console.log(response.data);
  })
  .catch((error) => {
    console.error(error);
  });
```

## 5. React Native Firebase

React Native Firebase is a library that provides a set of Firebase services for React Native applications. It allows you to easily integrate Firebase features, such as authentication, real-time database, cloud messaging, and more, into your React Native apps. React Native Firebase supports both iOS and Android platforms.

### Installation and Setup

To install React Native Firebase, use the following command:

```shell
npm install @react-native-firebase/app
```

Next, you need to install the specific Firebase modules for the services you want to use. For example, to install the authentication module, use the following command:

```shell
npm install @react-native-firebase/auth
```

To set up React Native Firebase in your app, you need to configure the Firebase project and initialize the Firebase app. Here's an example:

```javascript
import { initializeApp } from '@react-native-firebase/app';

const firebaseConfig = {
  // Your Firebase config
};

initializeApp(firebaseConfig);
```

### Authentication

React Native Firebase provides an easy-to-use API for authentication. Here's an example of how to sign in a user using email and password:

```javascript
import { signInWithEmailAndPassword } from '@react-native-firebase/auth';

function signIn(email, password) {
  signInWithEmailAndPassword(email, password)
    .then((userCredential) => {
      const user = userCredential.user;
      console.log('Signed in:', user.email);
    })
    .catch((error) => {
      console.error(error);
    });
}
```

### Real-time Database

React Native Firebase also provides real-time database functionality through the Firebase Realtime Database module. Here's an example of how to read data from the database:

```javascript
import database from '@react-native-firebase/database';

function readData() {
  database()
    .ref('/users')
    .once('value')
    .then((snapshot) => {
      const users = snapshot.val();
      console.log('Users:', users);
    })
    .catch((error) => {
      console.error(error);
    });
}
```

In this example, we read the data from the `/users` node in the database and log the result.

## 6. React Native Vector Icons

React Native Vector Icons is a library that provides a collection of customizable icons for React Native applications. It offers a wide range of icon sets, such as Material Icons, FontAwesome, and more. React Native Vector Icons allows you to easily include icons in your app and customize their appearance.

```shell
npm install react-native-vector-icons
```

After the installation, you need to link the library to your app. Use the following command to link the library automatically:

```shell
npx react-native link react-native-vector-icons
```

To use icons from React Native Vector Icons, import the icon component and render it in your app. Here's an example:

```javascript
import Icon from 'react-native-vector-icons/MaterialIcons';

function App() {
  return (
    <Icon name="star" size={30} color="gold" />
  );
}
```

### Icon Usage

To use an icon, create an instance of the icon component and specify its name, size, and color. The `name` prop represents the name of the icon from the selected icon set. The `size` prop determines the size of the icon, and the `color` prop sets the color of the icon.

```javascript
import Icon from 'react-native-vector-icons/MaterialIcons';

function App() {
  return (
    <Icon name="star" size={30} color="gold" />
  );
}
```

### Customization

React Native Vector Icons allows you to customize the appearance of icons by applying styles to them. You can use the `style` prop to apply custom styles, such as changing the color or size of the icon.

```javascript
import Icon from 'react-native-vector-icons/MaterialIcons';

function App() {
  return (
    <Icon name="star" size={30} color="gold" style={{ backgroundColor: 'black' }} />
  );
}
```

In this example, we apply a black background color to the icon using the `style` prop.

## What is React Native Styling?

React Native Styling refers to the process of defining and applying styles to components in a React Native application. Styles in React Native are similar to CSS stylesheets, but they are written in JavaScript. This allows for a more dynamic and flexible approach to styling, as styles can be defined and modified programmatically.

CSS-in-JS libraries for React Native provide a way to write styles directly in JavaScript code, eliminating the need for separate stylesheets. This approach offers several benefits, including better encapsulation, improved code reusability, and enhanced developer experience.

### Introduction to React Native

React Native is an open-source framework developed by Facebook for building mobile applications using JavaScript and React. It allows developers to write code once and deploy it on both iOS and Android platforms. React Native utilizes native components to render UI elements, resulting in a highly performant and native-like user experience.

### CSS-in-JS Libraries

CSS-in-JS libraries provide a way to write CSS styles directly in JavaScript code. They offer a range of features and advantages over traditional CSS stylesheets, including improved modularity, better code organization, and enhanced developer experience. These libraries generate CSS styles dynamically at runtime, making it easier to create dynamic and responsive user interfaces.

### Benefits of CSS-in-JS in React Native

Using CSS-in-JS libraries for styling React Native components offers several benefits:

1. **Improved Modularity**: Styles are scoped to individual components, making it easier to manage and reuse styles across the application.

2. **Enhanced Developer Experience**: Writing styles in JavaScript provides better tooling support, including code completion, linting, and easier debugging.

3. **Dynamic Styling**: CSS-in-JS libraries allow for dynamic styling based on props or state, making it easier to create interactive and responsive user interfaces.

4. **Theming**: Styles can be easily customized and themed, allowing for consistent branding across the application.

5. **Performance Optimization**: CSS-in-JS libraries generate optimized styles at runtime, reducing the size of the generated CSS and improving performance.

## Popular CSS-in-JS Libraries for React Native

There are several CSS-in-JS libraries available for styling React Native components. In this tutorial, we will explore the following popular libraries:

- Styled Components
- Emotion
- Glamorous
- JSS
- Radium
- Aphrodite

Each of these libraries has its own unique features and advantages. We will go through the installation process and explore the basic usage, styling components, dynamic styling, theming, and media queries for each library.

## Styled Components

Styled Components is a popular CSS-in-JS library for React Native that allows you to write styles directly in your JavaScript code. It provides a clean and intuitive API for defining and applying styles to components.

### Installation

To install Styled Components, you can use npm or yarn:

```shell
npm install styled-components
```

or

```shell
yarn add styled-components
```

### Basic Usage

Once installed, you can import the `styled` function from the `styled-components` package and use it to create styled components. Here's an example:

```jsx
import styled from 'styled-components';

const Button = styled.View`
  background-color: #007bff;
  padding: 10px 20px;
  border-radius: 5px;
`;

const Text = styled.Text`
  color: white;
  font-size: 16px;
`;

const App = () => {
  return (
    <Button>
      <Text>Click me</Text>
    </Button>
  );
};
```

In this example, we define a `Button` component using the `styled` function. The styles are defined using a template literal syntax, similar to CSS stylesheets. The `Button` component is then rendered with a nested `Text` component.

### Styling Components

Styled Components allow you to apply styles to components in a declarative manner. You can pass props to your styled components and use them to conditionally apply styles. Here's an example:

```jsx
const Button = styled.View`
  background-color: ${props => (props.primary ? '#007bff' : 'white')};
  padding: 10px 20px;
  border-radius: 5px;
`;

const Text = styled.Text`
  color: ${props => (props.primary ? 'white' : '#007bff')};
  font-size: 16px;
`;

const App = () => {
  return (
    <Button primary>
      <Text primary>Click me</Text>
    </Button>
  );
};
```

In this example, the `Button` and `Text` components have a `primary` prop which determines their styles. If the `primary` prop is `true`, the background color and text color will be set to the primary color, otherwise, it will be set to the secondary color.

### Dynamic Styling

Styled Components also support dynamic styling based on the component's props or state. This allows you to create interactive and responsive user interfaces. Here's an example:

```jsx
const Button = styled.View`
  background-color: #007bff;
  padding: 10px 20px;
  border-radius: 5px;
  opacity: ${props => (props.disabled ? 0.5 : 1)};
  cursor: ${props => (props.disabled ? 'not-allowed' : 'pointer')};
`;

const Text = styled.Text`
  color: white;
  font-size: 16px;
`;

const App = () => {
  const [disabled, setDisabled] = useState(false);

  const handleClick = () => {
    setDisabled(true);
  };

  return (
    <Button disabled={disabled} onPress={handleClick}>
      <Text>Click me</Text>
    </Button>
  );
};
```

In this example, the `Button` component has a `disabled` prop which determines its opacity and cursor style. If the `disabled` prop is `true`, the button will be partially transparent and the cursor will be set to 'not-allowed'. When the button is clicked, the `disabled` state is updated to `true`, disabling the button.

### Theming

Styled Components make theming easy by allowing you to define global styles that can be easily customized. You can create a `ThemeProvider` component and pass a theme object to it. Here's an example:

```jsx
import { ThemeProvider } from 'styled-components';

const theme = {
  primaryColor: '#007bff',
  secondaryColor: '#6c757d',
};

const Button = styled.View`
  background-color: ${props => props.theme.primaryColor};
  padding: 10px 20px;
  border-radius: 5px;
`;

const Text = styled.Text`
  color: ${props => props.theme.secondaryColor};
  font-size: 16px;
`;

const App = () => {
  return (
    <ThemeProvider theme={theme}>
      <Button>
        <Text>Click me</Text>
      </Button>
    </ThemeProvider>
  );
};
```

In this example, we define a `theme` object with primary and secondary colors. The `Button` component uses the `theme.primaryColor` for its background color, and the `Text` component uses the `theme.secondaryColor` for its text color. The `ThemeProvider` component wraps the `Button` and `Text` components, providing the theme object to them.

### Media Queries

Styled Components also support media queries, allowing you to define styles based on the screen size or other media features. You can use the `css` helper function and the `min-width` or `max-width` media queries to define responsive styles. Here's an example:

```jsx
const Button = styled.View`
  background-color: #007bff;
  padding: 10px 20px;
  border-radius: 5px;

  ${props =>
    props.theme.media.desktop`
    padding: 20px 40px;
  `}
`;

const Text = styled.Text`
  color: white;
  font-size: 16px;

  ${props =>
    props.theme.media.desktop`
    font-size: 24px;
  `}
`;

const App = () => {
  return (
    <ThemeProvider
      theme={{
        media: {
          desktop: `@media screen and (min-width: 768px)`,
        },
      }}
    >
      <Button>
        <Text>Click me</Text>
      </Button>
    </ThemeProvider>
  );
};
```

In this example, we define a `media` object in the theme with a `desktop` key that contains a media query for screens with a minimum width of 768px. The `Button` component and the `Text` component have styles defined within the `props.theme.media.desktop` block, which will be applied only on screens that match the media query.

## Exploring Emotion

Emotion is another popular CSS-in-JS library for React Native that provides a powerful and flexible way to style components. It offers a wide range of features and has a focus on performance and developer experience.

### Installation

To install Emotion, you can use npm or yarn:

```shell
npm install @emotion/react @emotion/native
```

or

```shell
yarn add @emotion/react @emotion/native
```

### Basic Usage

Once installed, you can import the `css` function from the `@emotion/native` package and use it to create styled components. Here's an example:

```jsx
import { css } from '@emotion/native';

const Button = ({ children }) => (
  <View
    style={css`
      background-color: #007bff;
      padding: 10px 20px;
      border-radius: 5px;
    `}
  >
    <Text
      style={css`
        color: white;
        font-size: 16px;
      `}
    >
      {children}
    </Text>
  </View>
);

const App = () => {
  return <Button>Click me</Button>;
};
```

In this example, we define a `Button` component using the `css` function from `@emotion/native`. The styles are defined using template literal syntax, similar to CSS stylesheets. The `Button` component is then rendered with a nested `Text` component.

### Styled Components vs Emotion

Both Styled Components and Emotion provide similar functionality for styling React Native components. However, there are some differences in their APIs and features.

Styled Components has a more declarative API and allows you to define styles using tagged template literals. It also provides support for theming, dynamic styling, and media queries out of the box. On the other hand, Emotion has a more imperative API and allows you to define styles using the `css` function. It offers more fine-grained control over styles and provides better performance optimizations.

When choosing between Styled Components and Emotion, it ultimately comes down to personal preference and the specific requirements of your project.

### Advanced Features

Emotion provides several advanced features that can help you build more complex and performant styles in your React Native applications. Some of these features include style composition, keyframes animations, and server-side rendering.

To learn more about these advanced features, refer to the Emotion documentation.

## Glamorous: Simple and Elegant Styling

Glamorous is a lightweight CSS-in-JS library for React Native that focuses on simplicity and elegance. It provides a simple and intuitive API for styling components and supports advanced features like theming and global styles.

### Installation

To install Glamorous, you can use npm or yarn:

```shell
npm install glamorous-native
```

or

```shell
yarn add glamorous-native
```

### Basic Usage

Once installed, you can import the `glamorous` function from the `glamorous-native` package and use it to create styled components. Here's an example:

```jsx
import glamorous from 'glamorous-native';

const Button = glamorous.view({
  backgroundColor: '#007bff',
  padding: 10,
  borderRadius: 5,
});

const Text = glamorous.text({
  color: 'white',
  fontSize: 16,
});

const App = () => {
  return (
    <Button>
      <Text>Click me</Text>
    </Button>
  );
};
```

In this example, we define a `Button` component using the `glamorous.view` function. The styles are defined using a JavaScript object syntax. The `Button` component is then rendered with a nested `Text` component.

### Customizing Styles

Glamorous allows you to customize styles by passing a props object to the styled components. You can use the `props` argument in the style function to conditionally apply styles. Here's an example:

```jsx
const Button = glamorous.view(props => ({
  backgroundColor: props.primary ? '#007bff' : 'white',
  padding: 10,
  borderRadius: 5,
}));

const Text = glamorous.text(props => ({
  color: props.primary ? 'white' : '#007bff',
  fontSize: 16,
}));

const App = () => {
  return (
    <Button primary>
      <Text primary>Click me</Text>
    </Button>
  );
};
```

In this example, the `Button` and `Text` components have a `primary` prop which determines their styles. If the `primary` prop is `true`, the background color and text color will be set to the primary color, otherwise, it will be set to the secondary color.

### Dynamic Styling

Glamorous also supports dynamic styling based on the component's props or state. This allows you to create interactive and responsive user interfaces. Here's an example:

```jsx
const Button = glamorous.view(props => ({
  backgroundColor: '#007bff',
  padding: 10,
  borderRadius: 5,
  opacity: props.disabled ? 0.5 : 1,
  cursor: props.disabled ? 'not-allowed' : 'pointer',
}));

const Text = glamorous.text({
  color: 'white',
  fontSize: 16,
});

const App = () => {
  const [disabled, setDisabled] = useState(false);

  const handleClick = () => {
    setDisabled(true);
  };

  return (
    <Button disabled={disabled} onPress={handleClick}>
      <Text>Click me</Text>
    </Button>
  );
};
```

In this example, the `Button` component has a `disabled` prop which determines its opacity and cursor style. If the `disabled` prop is `true`, the button will be partially transparent and the cursor will be set to 'not-allowed'. When the button is clicked, the `disabled` state is updated to `true`, disabling the button.

## JSS: CSS-in-JS for React Native

JSS is a powerful CSS-in-JS library that allows you to write styles in JavaScript and apply them to React Native components. It provides a flexible and efficient way to manage styles and supports advanced features like style composition and dynamic styling.

### Installation

To install JSS, you can use npm or yarn:

```shell
npm install jss react-jss
```

or

```shell
yarn add jss react-jss
```

### Basic Usage

Once installed, you can import the `create` function from the `jss` package and use it to create a JSS instance. You can then use the `useStyles` hook from the `react-jss` package to apply styles to your components. Here's an example:

```jsx
import { create } from 'jss';
import { useStyles } from 'react-jss';

const jss = create();

const styles = {
  button: {
    backgroundColor: '#007bff',
    padding: 10,
    borderRadius: 5,
  },
  text: {
    color: 'white',
    fontSize: 16,
  },
};

const Button = () => {
  const classes = useStyles(styles);

  return (
    <View style={classes.button}>
      <Text style={classes.text}>Click me</Text>
    </View>
  );
};

const App = () => {
  return <Button />;
};
```

In this example, we create a JSS instance using the `create` function from the `jss` package. We define the styles using a JavaScript object syntax. The `useStyles` hook from the `react-jss` package is used to apply the styles to the `Button` component. The `classes` object returned by the `useStyles` hook contains the generated class names for the styles.

### Style Composition

JSS allows you to compose styles by merging multiple style objects together. This can be useful for creating reusable and modular styles. Here's an example:

```jsx
const styles = {
  button: {
    backgroundColor: '#007bff',
    padding: 10,
    borderRadius: 5,
  },
  primaryButton: {
    color: 'white',
  },
};

const Button = ({ primary }) => {
  const classes = useStyles(styles);

  return (
    <View style={[classes.button, primary && classes.primaryButton]}>
      <Text>Click me</Text>
    </View>
  );
};
```

In this example, we define a `primaryButton` style object that contains additional styles for a primary button. We conditionally apply the `primaryButton` styles to the `Button` component based on the `primary` prop.

### Dynamic Styling

JSS supports dynamic styling based on the component's props or state. This allows you to create interactive and responsive user interfaces. Here's an example:

```jsx
const styles = {
  button: {
    backgroundColor: '#007bff',
    padding: 10,
    borderRadius: 5,
    opacity: props => (props.disabled ? 0.5 : 1),
    cursor: props => (props.disabled ? 'not-allowed' : 'pointer'),
  },
  text: {
    color: 'white',
    fontSize: 16,
  },
};

const Button = () => {
  const [disabled, setDisabled] = useState(false);
  const classes = useStyles(styles, { disabled });

  const handleClick = () => {
    setDisabled(true);
  };

  return (
    <View style={classes.button} onPress={handleClick}>
      <Text style={classes.text}>Click me</Text>
    </View>
  );
};
```

In this example, the `button` style object has dynamic styles for the `opacity` and `cursor` properties based on the `disabled` prop. When the `disabled` state is `true`, the button will be partially transparent and the cursor will be set to 'not-allowed'. When the button is clicked, the `disabled` state is updated to `true`, disabling the button.
