Create a fully responsive React Native app for all supported platforms

📢 Introduction

This package makes it super easy to create apps responsive that work perfectly on all different screen sizes in React Native (like font size, width, height, and more), making sure everything looks great on any device, from extra small to extra large. You can also tweak how things scale and adjust settings to make everything just the way you want it.

💫 Features

• Easy to use: Effortlessly implement size scaling and responsive design.
• Cross-platform: Works seamlessly across multiple platforms and devices.

• Various responsive hooks provided: Use these hooks based on your specific use cases.
• Customizable scaling: Define base widths for specific dimension types (xs, sm, ... 2xl) for precise control.
• Responsive percentage-based sizing: Adjust sizing based on width or height by PixelRatio.
• Media query hook: Detect dimension types by using the useMediaQuery hook. You can also override default thresholds as needed. This hook can be used in the provider to automatically detect and respond based on the configurations.

🚀 Quick Start

Starting from v2, you can easily create your styles using the createRStyle or useRStyle hooks

Use createRStyle in a similar way to when you use StyleSheet.create:

1import * as React from 'react';
2import { View, Text } from 'react-native';
3import { createRStyle } from 'react-native-full-responsive';
4
5const SIZE = 20;
6
7export default function App() {
8  return (
9    <View style={styles.container}>
10      <View style={styles.box}>
11        <Text style={styles.textBold}>My awesome responsive text!</Text>
12      </View>
13    </View>
14  );
15}
16
17const styles = createRStyle({
18  container: {
19    flex: 1,
20    alignItems: 'center',
21    justifyContent: 'center',
22  },
23  box: {
24    height: `${SIZE * 3}rs`,
25    justifyContent: 'center',
26    backgroundColor: 'yellow',
27    marginVertical: `${SIZE}rs`,
28    paddingHorizontal: `${SIZE / 2}rs`,
29  },
30  textBold: {
31    fontWeight: 'bold',
32    fontSize: `${SIZE}rs`,
33  },
34});

Alternatively, use useRStyle to create dynamic styles that change when dimensions, bases, or types are modified:

1import * as React from 'react';
2import { View, Text } from 'react-native';
3import { FRProvider, useRStyle } from 'react-native-full-responsive';
4
5const SIZE = 20;
6
7const ResponsiveBox: React.FC = () => {
8  const styles = useRStyle({
9    container: {
10      flex: 1,
11      alignItems: 'center',
12      justifyContent: 'center',
13    },
14    box: {
15      height: `${SIZE * 3}rs`,
16      justifyContent: 'center',
17      backgroundColor: 'yellow',
18      marginVertical: `${SIZE}rs`,
19      paddingHorizontal: `${SIZE / 2}rs`,
20    },
21    textBold: {
22      fontWeight: 'bold',
23      fontSize: `${SIZE}rs`,
24    },
25  });
26
27  return (
28    <View style={styles.container}>
29      <View style={styles.box}>
30        <Text style={styles.textBold}>My awesome responsive text!</Text>
31      </View>
32    </View>
33  );
34};
35
36export default function App() {
37  return (
38    <FRProvider type="sm">
39      <ResponsiveBox />
40    </FRProvider>
41  );
42}

Alternatively, make use of the responsive methods and hooks that are available from v1:

1import * as React from 'react';
2import { Text } from 'react-native';
3import { useRM, FRProvider } from 'react-native-full-responsive';
4//...
5
6const MyComponent = () => {
7  const { rs } = useRM();
8
9  const scaledValue = rs(20);
10
11  return (
12    <Text style={{ fontSize: scaledValue }}>My awesome responsive text!</Text>
13  );
14};
15
16export default function App() {
17  return (
18    <FRProvider>
19      <MyComponent />
20    </FRProvider>
21  );
22}
