React native responsive manager.
npm install @lomray/react-native-responsive





The best way is to convert pixels to screen percentages.
Only in this case will each element of the design look in the same proportions, regardless of how wide or elongated the device’s screen is.
There is also a built-in ability to set styles for different orientations conveniently.
Therefore, relative to the maximum height and width of the device, we can calculate what percentage of the width or height should be occupied by a specific layout element.
npm or yarn
``sh
npm install --save @lomray/react-native-responsive
yarn add @lomray/react-native-responsive
`
typescript
/**
* src/services/responsive-manager.ts
*/
import { ResponsiveManager } from '@lomray/react-native-responsive';const { fs, hp, wp } = new ResponsiveManager({ height: 844, width: 390 });
export { fs, hp, wp };
`| Helper | Description |
|:-------|:-----------------------------------------------------------------------|
| wp | Calculates width value from px to independent pixel (screen percent). |
| hp | Calculates height value from px to independent pixel (screen percent). |
| fs | Works as 'wp', but for the fonts size. |
Each function has the same parameters:
(value: number, disableRatio = false) => number.By default, DIMENSIONS_RATIO is used to reduce the layout for devices with larger screens.
Therefore, we don't need to do the layout based on breakpoints with these helpers.
But we still have the option to disable this for specific layout cases.

#### 1.1. Create styles.
`typescript
import { StyleSheet } from 'react-native';
import { fs, hp, wp } from '@services/responsive-manager';const styles = StyleSheet.create({
section: {
paddingHorizontal: wp(24),
height: hp(200),
margin: hp(5),
width: wp(380),
},
title: {
fontSize: fs(24),
fontWeight: '600',
},
});
export default styles;
`#### 1.2. Use created styles in the component.
`typescript jsx
import React, { FC } from 'react';
import { Text, View } from 'react-native';
import styles from './styles';interface ISection {
title: string;
}
const Section: FC = ({ title }) => (
{title}
);
export default Section;
`$3
#### 2.1. Use styles as a function to access additional parameters.
`typescript
import { TParams } from '@lomray/react-native-responsive';
import { StyleSheet } from 'react-native';
import { fs, hp, wp } from '@services/responsive-manager';const styles = ({ orientation }: TParams) => StyleSheet.create({
section: {
paddingHorizontal: wp(24),
height: hp(200),
margin: hp(5),
justifyContent: 'center',
borderWidth: 1,
...(orientation === 'portrait'
? {
backgroundColor: 'white',
borderColor: 'black',
}
: {
backgroundColor: 'black',
borderColor: 'white',
width: wp(220),
}),
},
title: {
fontSize: fs(24),
fontWeight: '600',
color: orientation === 'portrait' ? 'black' : 'white',
},
description: {
marginTop: hp(8),
fontSize: fs(18),
fontWeight: '400',
color: orientation === 'portrait' ? 'black' : 'white',
},
});
export default styles;
`#### 2.2. Use created styles in the component using the useStyles hook.
`typescript jsx
import { useStyles } from '@lomray/react-native-responsive';
import React, { FC } from 'react';
import { Text, View } from 'react-native';
import stylesheet from './styles';interface ISection {
title: string;
}
const Section: FC = ({ title }) => {
const styles = useStyles(stylesheet);
return (
{title}
);
};
export default Section;
`$3
#### 3.1. Parameters from the component can be passed to the stylesheet.
The parameters will always contain "orientation" and also custom props that you pass by the second argument of the useStyles hook.
`typescript jsx
/**
* index.tsx
*/
import { useStyles } from '@lomray/react-native-responsive';
import React from 'react';
import { View } from 'react-native';
import stylesheet from './styles';const Component = () => {
const styles = useStyles(stylesheet, { isWhite: true });
return ;
};
export default Component;
``typescript jsx
/*
* styles.ts
*/
import { TParams } from '@lomray/react-native-responsive';
import { StyleSheet } from 'react-native';interface ICustomParams {
isWhite: boolean;
}
const styles = ({ isWhite }: TParams) => StyleSheet.create({
wrapper: {
color: isWhite ? 'white' : 'black',
},
});
export default styles;
