## Notes

### React Native New Arc

We are working on upgrading our UI Library to support the new React Native Architecture.
Currently, we support React Native 0.73, and we plan to support React Native 0.77 next.
While we don’t have a timeline yet, this is part of our roadmap.

## Installing

See setup instructions [here](https://wix.github.io/react-native-ui-lib/docs/getting-started/setup).

### New Major Version 6.0

See [breaking changes](https://wix.github.io/react-native-ui-lib/docs/getting-started/v6)

### For React Native >= 0.60.0

please use `react-native-ui-lib`

### For React Native < 0.60.0

please use `react-native-ui-lib@^3.0.0`

## Create your own Design System in 3 easy steps

### Step 1

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

```js
// 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

```js
// 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](https://wix.github.io/react-native-ui-lib/docs/foundation/modifiers).

```jsx
// 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>
    );
  }
}
```
