Import from Design System Folder

Import from Design System Folder

Re-export dependencies from a design system folder. App code imports from there, not directly from packages. This enables global changes and easy refactoring.

Incorrect (imports directly from package):

import { View, Text } from 'react-native'
import { Button } from '@ui/button'

function Profile() {
  return (
    <View>
      <Text>Hello</Text>
      <Button>Save</Button>
    </View>
  )
}

Correct (imports from design system):

components/view.tsx

import { View as RNView } from 'react-native'

// ideal: pick the props you will actually use to control implementation
export function View(
  props: Pick<React.ComponentProps<typeof RNView>, 'style' | 'children'>
) {
  return <RNView {...props} />
}

components/text.tsx

export { Text } from 'react-native'

components/button.tsx

export { Button } from '@ui/button'

import { View } from '@/components/view'
import { Text } from '@/components/text'
import { Button } from '@/components/button'

function Profile() {
  return (
    <View>
      <Text>Hello</Text>
      <Button>Save</Button>
    </View>
  )
}

Start by simply re-exporting. Customize later without changing app code.
