## 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):**
|
|
|
|
```tsx
|
|
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):**
|
|
|
|
```tsx
|
|
// 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} />;
|
|
}
|
|
```
|
|
|
|
```tsx
|
|
// components/text.tsx
|
|
export { Text } from "react-native";
|
|
```
|
|
|
|
```tsx
|
|
// components/button.tsx
|
|
export { Button } from "@ui/button";
|
|
```
|
|
|
|
```tsx
|
|
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.
