Progressive Rendering States - -Each chart renderer accepts a `streaming?: boolean` prop and handles three states: - -### Skeleton state -Triggered when we have `type` but insufficient data to render (no `rows` yet, or `series` not received for time-series). - -- Card with the composable `Chart.Surface` shell -- Skeleton shimmer filling the plot area -- Title shown if available -- Chart type icon (line/bar/pie) in the skeleton center - -### Partial state -Triggered when `streaming={true}` and we have at least one complete row. - -- Chart renders with available data points -- Time-series: line/bars grow left-to-right as rows arrive. Subtle pulse on the rightmost point. -- Distribution: slices appear and angles redistribute with CSS transitions -- Data table: rows appear top-to-bottom, last row fades in -- Legend pills visible (from `series` field) - -### Complete state -Triggered when `streaming` is false/undefined (JSON fully parsed). - -- Full chart with all data -- Pulse animation removed -- This is the steady state for scrolling back through chat history - -### Transition -No explicit transition animation between partial and complete. The chart simply stops growing -- the last row arrives, the pulse stops. This feels natural because the chart was already rendering correctly with partial data. - ---- - -## 4. Chart Renderer Rewrite - -Both time-series and distribution renderers are rewritten to use the dashboard's composable chart system. - -### Time-series renderer - -Uses: -- `Chart.Surface` for the card wrapper (replaces hand-rolled ``) -- `Chart.Content` for loading/error state handling -- `Chart.Plot` for the Recharts container with consistent background -- `CartesianGrid` with `chartCartesianGridDefault` tokens -- `XAxis` / `YAxis` with `chartAxisTickDefault` tokens and `chartAxisYWidthCompact` -- `chartSeriesColorAtIndex()` for theme-aware series colors (replaces hardcoded `CHART_COLORS`) -- `Chart.createRechartsSingleValueTooltip()` for tooltips (replaces custom tooltip JSX) -- `chartLegendPillClassName` for footer legend pills -- Interactive legend: click a pill to toggle that series on/off (using `activeIndex` state) -- `formatMetricNumber` for axis tick formatting (replaces local `formatNumber`) - -Height: 200px (up from 180px to match dashboard charts). - -### Distribution renderer - -Uses: -- Same composable shell (Surface, Content, Plot) -- `chartSeriesColorAtIndex()` for slice colors -- Dashboard tooltip pattern -- Legend pills in footer with percentages -- Interactive hover with `activeShape` (already implemented, just needs composable tokens) - -Height: 220px (up from 200px). - -### Data table renderer - -Minimal changes: -- Adapt to flat `columns`/`align`/`rows` arrays instead of `columns` objects -- Use dashboard table styling tokens if available -- No composable chart shell needed (it's a table, not a chart) - -### Transform layer - -New transform functions in the registry that convert row-oriented format to what Recharts expects: - -```typescript -// Time-series: rows → [{x, series1, series2, ...}] -function transformTimeSeriesRows(series: string[], rows: unknown[][]) { - return rows - .filter(row => row.length === series.length + 1) // drop partial rows - .map(([x, ...values]) => ({ - x, - ...Object.fromEntries(series.map((key, i) => [key, values[i]])) - })); -} - -// Distribution: rows → [{name, value}] -function transformDistributionRows(rows: unknown[][]) { - return rows - .filter(row => row.length >= 2) - .map(([name, value]) => ({ name: String(name), value: Number(value) })); -} -``` - -These transforms are memoized on `rows.length` so they don't re-compute when only the last (potentially partial) row changes. - ---- - -## 5. Prompt Changes - -Update `ANALYTICS_CHART_RULES` in `apps/api/src/ai/prompts/analytics.ts` to document the new row-oriented format with examples for each chart type. Remove the old column-oriented examples entirely. - -Update the few-shot examples in `ANALYTICS_EXAMPLES` to use the new format. - ---- - -## 6. Zod Schema Updates - -Update `apps/dashboard/lib/ai-components/schemas.ts` to validate the new row-oriented format: - -- `timeSeriesSchema`: requires `series` (string array) and `rows` (array of arrays) -- `distributionSchema`: requires `rows` (array of [string, number] tuples) -- `dataTableSchema`: requires `columns` (string array), `rows` (array of arrays), optional `align` -- Non-chart schemas: unchanged - ---- - -## 7. Files Changed - -| File | Change | -|---|---| -| `lib/ai-components/parser.ts` | Add `repairPartialJSON()`, emit `streaming-component` segments | -| `lib/ai-components/types.ts` | New row-oriented input types, `streaming-component` segment type | -| `lib/ai-components/schemas.ts` | Rewrite chart schemas for row-oriented format | -| `lib/ai-components/registry.tsx` | New validators/transforms for row format | -| `components/ai-elements/ai-component.tsx` | Accept `streaming` prop, pass to renderers | -| `lib/ai-components/renderers/charts/time-series.tsx` | Full rewrite using Chart composable | -| `lib/ai-components/renderers/charts/distribution.tsx` | Full rewrite using Chart composable | -| `lib/ai-components/renderers/data-table.tsx` | Adapt to flat columns/rows format | -| `lib/ai-components/renderers/config.ts` | Remove `CHART_COLORS` (use composable palette) | -| `agent/_components/agent-messages.tsx` | Handle `streaming-component` segment type | -| `apps/api/src/ai/prompts/analytics.ts` | Update chart format in prompt rules and examples | - -No new files.

List Performance - -**Impact: HIGH** - -Optimizing virtualized lists (FlatList, LegendList, FlashList) -for smooth scrolling and fast updates. - -### 2.1 Avoid Inline Objects in renderItem - -**Impact: HIGH (prevents unnecessary re-renders of memoized list items)** - -Don't create new objects inside `renderItem` to pass as props. Inline objects - -create new references on every render, breaking memoization. Pass primitive - -values directly from `item` instead. - -**Incorrect: inline object breaks memoization** - -```tsx -function UserList({ users }: { users: User[] }) { - return ( - ( - - )} - /> - ) -} -``` - -**Incorrect: inline style object** - -```tsx -renderItem={({ item }) => ( - -)} -``` - -**Correct: pass item directly or primitives** - -```tsx -function UserList({ users }: { users: User[] }) { - return ( - ( - // Good: pass the item directly - - )} - /> - ) -} -``` - -**Correct: pass primitives, derive inside child** - -```tsx -renderItem={({ item }) => ( - -)} - -const UserRow = memo(function UserRow({ id, name, isActive }: Props) { - // Good: derive style inside memoized component - const backgroundColor = isActive ?

Items should then call it with a unique - -identifier. - -**Incorrect: creates a new callback on each render** - -```typescript -return ( - { - // bad: creates a new callback on each render - const onPress = () => handlePress(item.id) - return - }} - /> -) -``` - -**Correct: a single function instance passed to each item** - -```typescript -const onPress = useCallback(() => handlePress(item.id), [handlePress, item.id]) - -return ( - ( - - )} - /> -) -``` - -Reference: [https://example.com](https://example.com) - -### 2.3 Keep List Items Lightweight - -**Impact: HIGH (reduces render time for visible items during scroll)** - -List items should be as inexpensive as possible to render. Minimize hooks, avoid - -queries, and limit React Context access. Virtualized lists render many items - -during scroll—expensive items cause jank. - -**Incorrect: heavy list item** - -```tsx -function ProductRow({ id }: { id: string }) { - // Bad: query inside list item - const { data: product } = useQuery(['product', id], () => fetchProduct(id)) - // Bad: multiple context accesses - const theme = useContext(ThemeContext) - const user = useContext(UserContext) - const cart = useContext(CartContext) - // Bad: expensive computation - const recommendations = useMemo( - () => computeRecommendations(product), - [product] - ) - - return {/* ... */} -} -``` - -**Correct: lightweight list item** - -```tsx -function ProductRow({ name, price, imageUrl }: Props) { - // Good: receives only primitives, minimal hooks - return ( - - - {name} - {price} - - ) -} -``` - -**Move data fetching to parent:** - -```tsx -// Parent fetches all data once -function ProductList() { - const { data: products } = useQuery(['products'], fetchProducts) - - return ( - ( - - )} - /> - ) -} -``` - -**For shared values, use Zustand selectors instead of Context:** - -```tsx -// Incorrect: Context causes re-render when any cart value changes -function ProductRow({ id, name }: Props) { - const { items } = useContext(CartContext) - const inCart = items.includes(id) - // ... -} - -// Correct: Zustand selector only re-renders when this specific value changes -function ProductRow({ id, name }: Props) { - // use Set.has (created once at the root) instead of Array.includes() - const inCart = useCartStore((s) => s.items.has(id)) - // ... -} -``` - -**Guidelines for list items:** - -- No queries or data fetching - -- No expensive computations (move to parent or memoize at parent level) - -- Prefer Zustand selectors over React Context - -- Minimize useState/useEffect hooks - -- Pass pre-computed values as props - -The goal: list items should be simple rendering functions that take props and - -return JSX. - -### 2.4 Optimize List Performance with Stable Object References - -**Impact: CRITICAL (virtualization relies on reference stability)** - -Don't map or filter data before passing to virtualized lists. Virtualization - -relies on object reference stability to know what changed—new references cause - -full re-renders of all visible items. Attempt to prevent frequent renders at the - -list-parent level. - -Where needed, use context selectors within list items. - -**Incorrect: creates new object references on every keystroke** - -```tsx -function DomainSearch() { - const { keyword, setKeyword } = useKeywordZustandState() - const { data: tlds } = useTlds() - - // Bad: creates new objects on every render, reparenting the entire list on every keystroke - const domains = tlds.map((tld) => ({ - domain: `${keyword}.${tld.name}`, - tld: tld.name, - price: tld.price, - })) - - return ( - <> - - } - /> - - ) -} -``` - -**Correct: stable references, transform inside items** - -```tsx -const renderItem = ({ item }) => - -function DomainSearch() { - const { data: tlds } = useTlds() - - return ( - - ) -} - -function DomainItem({ tld }: { tld: Tld }) { - // good: transform within items, and don't pass the dynamic data as a prop - // good: use a selector function from zustand to receive a stable string back - const domain = useKeywordZustandState((s) => s.keyword + '.' + tld.name) - return {domain} -} -``` - -**Updating parent array reference:** - -```tsx -// good: creates a new array instance without mutating the inner objects -// good: parent array reference is unaffected by typing and updating "keyword" -const sortedTlds = tlds.toSorted((a, b) => a.name.localeCompare(b.name)) - -return -``` - -Creating a new array instance can be okay, as long as its inner object - -references are stable. For instance, if you sort a list of objects: - -Even though this creates a new array instance `sortedTlds`, the inner object - -references are stable. - -**With zustand for dynamic data: avoids parent re-renders** - -```tsx -function DomainItemFavoriteButton({ tld }: { tld: Tld }) { - const isFavorited = useFavoritesStore((s) => s.favorites.has(tld.id)) - return -} -``` - -Virtualization can now skip items that haven't changed when typing. Only visible - -items (~20) re-render on keystroke, rather than the parent. - -**Deriving state within list items based on parent data (avoids parent - -re-renders):** - -For components where the data is conditional based on the parent state, this - -pattern is even more important. For example, if you are checking if an item is - -favorited, toggling favorites only re-renders one component if the item itself - -is in charge of accessing the state rather than the parent: - -Note: if you're using the React Compiler, you can read React Context values - -directly within list items. Although this is slightly slower than using a - -Zustand selector in most cases, the effect may be negligible. - -### 2.5 Pass Primitives to List Items for Memoization - -**Impact: HIGH (enables effective memo() comparison)** - -When possible, pass only primitive values (strings, numbers, booleans) as props - -to list item components. Primitives enable shallow comparison in `memo()` to - -work correctly, skipping re-renders when values haven't changed. - -**Incorrect: object prop requires deep comparison** - -```tsx -type User = { id: string; name: string; email: string; avatar: string } - -const UserRow = memo(function UserRow({ user }: { user: User }) { - // memo() compares user by reference, not value - // If parent creates new user object, this re-renders even if data is same - return {user.name} -}) - -renderItem={({ item }) => } -``` - -This can still be optimized, but it is harder to memoize properly. - -**Correct: primitive props enable shallow comparison** - -```tsx -const UserRow = memo(function UserRow({ - id, - name, - email, -}: { - id: string - name: string - email: string -}) { - // memo() compares each primitive directly - // Re-renders only if id, name, or email actually changed - return {name} -}) - -renderItem={({ item }) => ( - -)} -``` - -**Pass only what you need:** - -```tsx -// Incorrect: passing entire item when you only need name - - -// Correct: pass only the fields the component uses - -``` - -**For callbacks, hoist or use item ID:** - -```tsx -// Incorrect: inline function creates new reference - handlePress(item.id)} /> - -// Correct: pass ID, handle in child - - -const UserRow = memo(function UserRow({ id, name }: Props) { - const handlePress = useCallback(() => { - // use id here - }, [id]) - return {name} -}) -``` - -Primitive props make memoization predictable and effective. - -**Note:** If you have the React Compiler enabled, you do not need to use - -`memo()` or `useCallback()`, but the object references still apply. - -### 2.6 Use a List Virtualizer for Any List - -**Impact: HIGH (reduced memory, faster mounts)** - -Use a list virtualizer like LegendList or FlashList instead of ScrollView with - -mapped children—even for short lists. Virtualizers only render visible items, - -reducing memory usage and mount time. ScrollView renders all children upfront, - -which gets expensive quickly. - -**Incorrect: ScrollView renders all items at once** - -```tsx -function Feed({ items }: { items: Item[] }) { - return ( - - {items.map((item) => ( - - ))} - - ) -} -// 50 items = 50 components mounted, even if only 10 visible -``` - -**Correct: virtualizer renders only visible items** - -```tsx -import { LegendList } from '@legendapp/list' - -function Feed({ items }: { items: Item[] }) { - return ( - } - keyExtractor={(item) => item.id} - estimatedItemSize={80} - /> - ) -} -// Only ~10-15 visible items mounted at a time -``` - -**Alternative: FlashList** - -```tsx -import { FlashList } from '@shopify/flash-list' - -function Feed({ items }: { items: Item[] }) { - return ( - } - keyExtractor={(item) => item.id} - /> - ) -} -``` - -Benefits apply to any screen with scrollable content—profiles, settings, feeds, - -search results. Default to virtualization. - -### 2.7 Use Compressed Images in Lists - -**Impact: HIGH (faster load times, less memory)** - -Always load compressed, appropriately-sized images in lists. Full-resolution - -images consume excessive memory and cause scroll jank.

Animation - -**Impact: HIGH** - -GPU-accelerated animations, Reanimated patterns, and avoiding -render thrashing during gestures. - -### 3.1 Animate Transform and Opacity Instead of Layout Properties - -**Impact: HIGH (GPU-accelerated animations, no layout recalculation)** - -Avoid animating `width`, `height`, `top`, `left`, `margin`, or `padding`. These trigger layout recalculation on every frame. Instead, use `transform` (scale, translate) and `opacity` which run on the GPU without triggering layout. - -**Incorrect: animates height, triggers layout every frame** - -```tsx -import Animated, { useAnimatedStyle, withTiming } from 'react-native-reanimated' - -function CollapsiblePanel({ expanded }: { expanded: boolean }) { - const animatedStyle = useAnimatedStyle(() => ({ - height: withTiming(expanded ? 200 : 0), // triggers layout on every frame - overflow: 'hidden', - })) - - return {children} -} -``` - -**Correct: animates scaleY, GPU-accelerated** - -```tsx -import Animated, { useAnimatedStyle, withTiming } from 'react-native-reanimated' - -function CollapsiblePanel({ expanded }: { expanded: boolean }) { - const animatedStyle = useAnimatedStyle(() => ({ - transform: [ - { scaleY: withTiming(expanded ? 1 : 0) }, - ], - opacity: withTiming(expanded ? 1 : 0), - })) - - return ( - - {children} - - ) -} -``` - -**Correct: animates translateY for slide animations** - -```tsx -import Animated, { useAnimatedStyle, withTiming } from 'react-native-reanimated' - -function SlideIn({ visible }: { visible: boolean }) { - const animatedStyle = useAnimatedStyle(() => ({ - transform: [ - { translateY: withTiming(visible ? 0 : 100) }, - ], - opacity: withTiming(visible ? 1 : 0), - })) - - return {children} -} -``` - -GPU-accelerated properties: `transform` (translate, scale, rotate), `opacity`.

Redundant state causes unnecessary re-renders and can drift out of sync. - -**Incorrect: redundant state** - -```tsx -function Cart({ items }: { items: Item[] }) { - const [total, setTotal] = useState(0) - const [itemCount, setItemCount] = useState(0) - - useEffect(() => { - setTotal(items.reduce((sum, item) => sum + item.price, 0)) - setItemCount(items.length) - }, [items]) - - return ( - - {itemCount} items - Total: ${total} - - ) -} -``` - -**Correct: derived values** - -```tsx -function Cart({ items }: { items: Item[] }) { - const total = items.reduce((sum, item) => sum + item.price, 0) - const itemCount = items.length - - return ( - - {itemCount} items - Total: ${total} - - ) -} -``` - -**Another example:** - -```tsx -// Incorrect: storing both firstName, lastName, AND fullName -const [firstName, setFirstName] = useState('') -const [lastName, setLastName] = useState('') -const [fullName, setFullName] = useState('') - -// Correct: derive fullName -const [firstName, setFirstName] = useState('') -const [lastName, setLastName] = useState('') -const fullName = `${firstName} ${lastName}` -``` - -State should be the minimal source of truth. Everything else is derived. - -Reference: [https://react.dev/learn/choosing-the-state-structure](https://react.dev/learn/choosing-the-state-structure) - -### 6.2 Use fallback state instead of initialState - -**Impact: MEDIUM (reactive fallbacks without syncing)** - -Use `undefined` as initial state and nullish coalescing (`??`) to fall back to - -parent or server values. State represents user intent only—`undefined` means - -"user hasn't chosen yet." This enables reactive fallbacks that update when the - -source changes, not just on initial render. - -**Incorrect: syncs state, loses reactivity** - -```tsx -type Props = { fallbackEnabled: boolean } - -function Toggle({ fallbackEnabled }: Props) { - const [enabled, setEnabled] = useState(defaultEnabled) - // If fallbackEnabled changes, state is stale - // State mixes user intent with default value - - return -} -``` - -**Correct: state is user intent, reactive fallback** - -```tsx -type Props = { fallbackEnabled: boolean } - -function Toggle({ fallbackEnabled }: Props) { - const [_enabled, setEnabled] = useState(undefined) - const enabled = _enabled ?? defaultEnabled - // undefined = user hasn't touched it, falls back to prop - // If defaultEnabled changes, component reflects it - // Once user interacts, their choice persists - - return -} -``` - -**With server data:** - -```tsx -function ProfileForm({ data }: { data: User }) { - const [_theme, setTheme] = useState(undefined) - const theme = _theme ?? data.theme - // Shows server value until user overrides - // Server refetch updates the fallback automatically - - return -} -``` - -### 6.3 useState Dispatch updaters for State That Depends on Current Value - -**Impact: MEDIUM (avoids stale closures, prevents unnecessary re-renders)** - -When the next state depends on the current state, use a dispatch updater - -(`setState(prev => ...)`) instead of reading the state variable directly in a - -callback. This avoids stale closures and ensures you're comparing against the - -latest value. - -**Incorrect: reads state directly** - -```tsx -const [size, setSize] = useState(undefined) - -const onLayout = (e: LayoutChangeEvent) => { - const { width, height } = e.nativeEvent.layout - // size may be stale in this closure - if (size?.width !== width || size?.height !== height) { - setSize({ width, height }) - } -} -``` - -**Correct: dispatch updater** - -```tsx -const [size, setSize] = useState(undefined) - -const onLayout = (e: LayoutChangeEvent) => { - const { width, height } = e.nativeEvent.layout - setSize((prev) => { - if (prev?.width === width && prev?.height === height) return prev - return { width, height } - }) -} -``` - -Returning the previous value from the updater skips the re-render. - -For primitive states, you don't need to compare values before firing a - -re-render. - -**Incorrect: unnecessary comparison for primitive state** - -```tsx -const [size, setSize] = useState(undefined) - -const onLayout = (e: LayoutChangeEvent) => { - const { width, height } = e.nativeEvent.layout - setSize((prev) => (prev === width ? prev : width)) -} -``` - -**Correct: sets primitive state directly** - -```tsx -const [size, setSize] = useState(undefined) - -const onLayout = (e: LayoutChangeEvent) => { - const { width, height } = e.nativeEvent.layout - setSize(width) -} -``` - -However, if the next state depends on the current state, you should still use a - -dispatch updater. - -**Incorrect: reads state directly from the callback** - -```tsx -const [count, setCount] = useState(0) - -const onTap = () => { - setCount(count + 1) -} -``` - -**Correct: dispatch updater** - -```tsx -const [count, setCount] = useState(0) - -const onTap = () => { - setCount((prev) => prev + 1) -} -``` - ---- - -## 7. State Architecture - -**Impact: MEDIUM** - -Ground truth principles for state variables and derived values. - -### 7.1 State Must Represent Ground Truth - -**Impact: HIGH (cleaner logic, easier debugging, single source of truth)** - -State variables—both React `useState` and Reanimated shared values—should - -represent the actual state of something (e.g., `pressed`, `progress`, `isOpen`), - -not derived visual values (e.g., `scale`, `opacity`, `translateY`). Derive - -visual values from state using computation or interpolation. - -**Incorrect: storing the visual output** - -```tsx -const scale = useSharedValue(1) - -const tap = Gesture.Tap() - .onBegin(() => { - scale.set(withTiming(0.95)) - }) - .onFinalize(() => { - scale.set(withTiming(1)) - }) - -const animatedStyle = useAnimatedStyle(() => ({ - transform: [{ scale: scale.get() }], -})) -``` - -**Correct: storing the state, deriving the visual** - -```tsx -const pressed = useSharedValue(0) // 0 = not pressed, 1 = pressed - -const tap = Gesture.Tap() - .onBegin(() => { - pressed.set(withTiming(1)) - }) - .onFinalize(() => { - pressed.set(withTiming(0)) - }) - -const animatedStyle = useAnimatedStyle(() => ({ - transform: [{ scale: interpolate(pressed.get(), [0, 1], [1, 0.95]) }], -})) -``` - -**Why this matters:** - -State variables should represent real "state", not necessarily a desired end - -result. - -1. **Single source of truth** — The state (`pressed`) describes what's - - happening; visuals are derived - -2. **Easier to extend** — Adding opacity, rotation, or other effects just - - requires more interpolations from the same state - -3. **Debugging** — Inspecting `pressed = 1` is clearer than `scale = 0.95` - -4. **Reusable logic** — The same `pressed` value can drive multiple visual - - properties - -**Same principle for React state:** - -```tsx -// Incorrect: storing derived values -const [isExpanded, setIsExpanded] = useState(false) -const [height, setHeight] = useState(0) - -useEffect(() => { - setHeight(isExpanded ? 200 : 0) -}, [isExpanded]) - -// Correct: derive from state -const [isExpanded, setIsExpanded] = useState(false) -const height = isExpanded ? 200 : 0 -``` - -State is the minimal truth.

React Compiler - -**Impact: MEDIUM** - -Compatibility patterns for React Compiler with React Native and -Reanimated. - -### 8.1 Destructure Functions Early in Render (React Compiler) - -**Impact: HIGH (stable references, fewer re-renders)** - -This rule is only applicable if you are using the React Compiler. - -Destructure functions from hooks at the top of render scope. Never dot into - -objects to call functions. Destructured functions are stable references; dotting - -creates new references and breaks memoization. - -**Incorrect: dotting into object** - -```tsx -import { useRouter } from 'expo-router' - -function SaveButton(props) { - const router = useRouter() - - // bad: react-compiler will key the cache on "props" and "router", which are objects that change each render - const handlePress = () => { - props.onSave() - router.push('/success') // unstable reference - } - - return -} -``` - -**Correct: destructure early** - -```tsx -import { useRouter } from 'expo-router' - -function SaveButton({ onSave }) { - const { push } = useRouter() - - // good: react-compiler will key on push and onSave - const handlePress = () => { - onSave() - push('/success') // stable reference - } - - return -} -``` - -### 8.2 Use .get() and .set() for Reanimated Shared Values (not .value) - -**Impact: LOW (required for React Compiler compatibility)** - -With React Compiler enabled, use `.get()` and `.set()` instead of reading or - -writing `.value` directly on Reanimated shared values. The compiler can't track - -property access—explicit methods ensure correct behavior. - -**Incorrect: breaks with React Compiler** - -```tsx -import { useSharedValue } from 'react-native-reanimated' - -function Counter() { - const count = useSharedValue(0) - - const increment = () => { - count.value = count.value + 1 // opts out of react compiler - } - - return - -``` - -**Correct: compound components** - -```tsx -import { Pressable, Text } from 'react-native' - -function Button({ children }: { children: React.ReactNode }) { - return {children} -} - -function ButtonText({ children }: { children: React.ReactNode }) { - return {children} -} - -function ButtonIcon({ children }: { children: React.ReactNode }) { - return <>{children} -} - -// Usage is explicit and composable - - - -``` - ---- - -## 11. Monorepo - -**Impact: LOW** - -Dependency management and native module configuration in -monorepos. - -### 11.1 Install Native Dependencies in App Directory - -**Impact: CRITICAL (required for autolinking to work)** - -In a monorepo, packages with native code must be installed in the native app's - -directory directly. Autolinking only scans the app's `node_modules`—it won't - -find native dependencies installed in other packages. - -**Incorrect: native dep in shared package only** - -```typescript -packages/ - ui/ - package.json # has react-native-reanimated - app/ - package.json # missing react-native-reanimated -``` - -Autolinking fails—native code not linked. - -**Correct: native dep in app directory** - -```json -// packages/app/package.json -{ - "dependencies": { - "react-native-reanimated": "3.16.1" - } -} -``` - -Even if the shared package uses the native dependency, the app must also list it - -for autolinking to detect and link the native code. - -### 11.2 Use Single Dependency Versions Across Monorepo - -**Impact: MEDIUM (avoids duplicate bundles, version conflicts)** - -Use a single version of each dependency across all packages in your monorepo. - -Prefer exact versions over ranges. Multiple versions cause duplicate code in - -bundles, runtime conflicts, and inconsistent behavior across packages. - -Use a tool like syncpack to enforce this. As a last resort, use yarn resolutions - -or npm overrides. - -**Incorrect: version ranges, multiple versions** - -```json -// packages/app/package.json -{ - "dependencies": { - "react-native-reanimated": "^3.0.0" - } -} - -// packages/ui/package.json -{ - "dependencies": { - "react-native-reanimated": "^3.5.0" - } -} -``` - -**Correct: exact versions, single source of truth** - -```json -// package.json (root) -{ - "pnpm": { - "overrides": { - "react-native-reanimated": "3.16.1" - } - } -} - -// packages/app/package.json -{ - "dependencies": { - "react-native-reanimated": "3.16.1" - } -} - -// packages/ui/package.json -{ - "dependencies": { - "react-native-reanimated": "3.16.1" - } -} -``` - -Use your package manager's override/resolution feature to enforce versions at - -the root.

Third-Party Dependencies - -**Impact: LOW** - -Wrapping and re-exporting third-party dependencies for -maintainability. - -### 12.1 Import from Design System Folder - -**Impact: LOW (enables global changes and easy refactoring)** - -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 ( - - Hello - - - ) -} -``` - -**Correct: imports from design system** - -```tsx -import { View } from '@/components/view' -import { Text } from '@/components/text' -import { Button } from '@/components/button' - -function Profile() { - return ( - - Hello - - - ) -} -``` - -Start by simply re-exporting. Customize later without changing app code. - ---- - -## 13. JavaScript - -**Impact: LOW** - -Micro-optimizations like hoisting expensive object creation. - -### 13.1 Hoist Intl Formatter Creation - -**Impact: LOW-MEDIUM (avoids expensive object recreation)** - -Don't create `Intl.DateTimeFormat`, `Intl.NumberFormat`, or - -`Intl.RelativeTimeFormat` inside render or loops.
