Create your own Design System in 3 easy steps

Step 1

Load your foundations and presets (colors, typography, spacings, etc...)

// FoundationConfig.js

import {Colors, Typography, Spacings} from 'react-native-ui-lib';

Colors.loadColors({
  primaryColor: '#2364AA',
  secondaryColor: '#81C3D7',
  textColor: '##221D23',
  errorColor: '#E63B2E',
  successColor: '#ADC76F',
  warnColor: '##FF963C'
});

Typography.loadTypographies({
  heading: {fontSize: 36, fontWeight: '600'},
  subheading: {fontSize: 28, fontWeight: '500'},
  body: {fontSize: 18, fontWeight: '400'},
});

Spacings.loadSpacings({
  page: 20,
  card: 12,
  gridGutter: 16
});

Step 2

Set default configurations to your components

// ComponentsConfig.js

import {ThemeManager} from 'react-native-ui-lib';

// with plain object
ThemeManager.setComponentTheme('Card', {
  borderRadius: 8
});

// with a dynamic function
ThemeManager.setComponentTheme('Button', (props, context) => {
  // 'square' is not an original Button prop, but a custom prop that can
  // be used to create different variations of buttons in your app
  if (props.square) {
    return {
      borderRadius: 0
    };
  }
});

Step 3

Use it all together. Your configurations will be applied on uilib components so you can use them easily with modifiers.

// MyScreen.js

import React, {Component} from 'react';
import {View, Text, Card, Button} from 'react-native-ui-lib';

class MyScreen extends Component {
  render() {
    return (
      <View flex padding-page>
        <Text heading marginB-s4>My Screen</Text>
        <Card height={100} center padding-card marginB-s4>
          <Text body>This is an example card </Text>
        </Card>
        
        <Button label="Button" body bg-primaryColor square></Button>
      </View>
    );
  }
}
