React Native Generator — Memoire Codegen Skill
Translates Memoire specs into production React Native components.
Maintains atomic design hierarchy and maps web primitives to native equivalents.
Mapping Rules
shadcn/ui to React Native
| shadcn Component | RN Equivalent | Notes |
|---|
| Button | Pressable + Text | Use Pressable over TouchableOpacity |
| Card | View with shadow styles | NativeWind shadow-md rounded-lg |
| Input | TextInput | Add returnKeyType, autoCapitalize |
| Badge | View + Text | Fixed height, rounded-full |
| Avatar | Image with fallback View | borderRadius: 9999 |
| Dialog | Modal | Use RN Modal with transparent |
| Select | Custom ActionSheet or Picker | Platform-specific |
| Separator | View with h-px bg-border | |
| Tabs | Custom with Pressable row | Horizontal scroll for overflow |
| Table | FlatList with header row | Virtualized by default |
| Switch | RN Switch | Map trackColor, thumbColor |
| Checkbox | Pressable + icon toggle | No native checkbox on RN |
| ScrollArea | ScrollView | Add showsVerticalScrollIndicator |
| Sheet | Modal + Animated.View | Bottom sheet pattern |
| Skeleton | Animated View with shimmer | Use Animated opacity loop |
Tailwind to NativeWind
- Web Tailwind classes map 1:1 in NativeWind 4.x
- Exceptions:
hover:, focus-visible: — replace with active: states
- Grid: Use
flex layout — RN has no CSS Grid
gap-* works in NativeWind, prefer over margin hacks
Atomic Folders (React Native)
| Level | Output Path |
|---|
| atom | components/ui/ |
| molecule | components/molecules/ |
| organism | components/organisms/ |
| template | components/templates/ |
| page | screens/ |
Component Template
import { View, Text, Pressable } from "react-native";
import type { ComponentProps } from "react";
interface {Name}Props {
// Generated from spec.props
}
export function {Name}({ ...props }: {Name}Props) {
return (
<View className="...">
{/* Component content */}
</View>
);
}
Guidelines
OBSERVE
- Read the ComponentSpec fully — check
level, variants, props, shadcnBase
- Check if a native equivalent already exists in the project
- Identify platform-specific requirements (iOS safe area, Android back handler)
PLAN
- Map each shadcn base to its RN equivalent from the table above
- Determine if platform branching is needed (
Platform.OS)
- Plan animation approach for interactive components
EXECUTE
- Generate component with NativeWind classes
- Export barrel file (
index.ts)
- Add platform-specific files only when behavior diverges (
.ios.tsx, .android.tsx)
VALIDATE
- Verify all imports resolve (no web-only packages)
- Check NativeWind classes are RN-compatible
- Ensure accessibility:
accessibilityLabel, accessibilityRole, accessibilityState
- No
onClick — use onPress
- No
className on Text without NativeWind — use style as fallback
Platform Patterns
Safe Area
import { useSafeAreaInsets } from "react-native-safe-area-context";
const insets = useSafeAreaInsets();
<View style={{ paddingTop: insets.top }}>
Haptics
import * as Haptics from "expo-haptics";
Haptics.impactAsync(Haptics.ImpactFeedbackStyle.Light);
Bottom Sheet
// Prefer @gorhom/bottom-sheet for production
import BottomSheet from "@gorhom/bottom-sheet";
Keyboard Avoidance
import { KeyboardAvoidingView, Platform } from "react-native";
<KeyboardAvoidingView behavior={Platform.OS === "ios" ? "padding" : "height"}>
