Styling React Native apps involves using a combination of built-in components, and external libraries to ensure your app looks great and performs well across different devices and screen sizes.
Here’s a guide to styling React Native apps:
Thank you for showing your Love and support for my blog (How to start with React native as ReactJS developers) [https://dev.to/hellonehha/how-to-start-with-react-native-as-reactjs-developer-2d61]
1. Using the StyleSheet API
React Native provides a built-in StyleSheet API to define styles. This API allows you to define styles similarly to CSS but in a JavaScript object format.
import { StyleSheet, Text, View } from 'react-native';
const App = () => {
return (
<View style={styles.container}>
<Text style={styles.text}>Hello, world!</Text>
</View>
);
};
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#f5f5f5',
},
text: {
fontSize: 20,
color: '#333',
},
});
export default App;
2. External Libraries
Styled Components: A popular library that allows you to write plain CSS in your React Native components.
import styled from 'styled-components/native';
const Container = styled.View`
flex: 1;
justify-content: center;
align-items: center;
background-color: papayawhip;
`;
const StyledText = styled.Text`
font-size: 24px;
color: palevioletred;
`;
3. Native Wind
NativeWind is a library for React Native that allows you to use Tailwind CSS directly in your React Native projects. It provides utility-first styling, which makes it easy to build responsive and consistent user interfaces
Once installed, and setup, you can use it like this:
import { Text, View } from 'react-native';
import { styled } from 'nativewind';
const App = () => {
return (
<View className="flex-1 justify-center items-center bg-gray-100">
<Text className="text-lg font-bold text-blue-500">
Hello, NativeWind!
</Text>
</View>
);
};
export default App;
4. Global Styles
To maintain consistency, create a styles.js file where you can define global styles.
// styles.js
import { StyleSheet } from 'react-native';
export default StyleSheet.create({
text: {
fontSize: 18,
color: '#333',
},
container: {
padding: 20,
},
});
Happy Learning!!
