Should be +platform-agnostic when possible. Examples: Button, Dialog, Menu, TextField. Put +these in `/components` if they are shared across screens. + +**Screens** are full-page components that represent a route in the app. They +often contain multiple components and handle layout for a page. New screens +should go in `/screens` (not `/view/screens`) to encourage better organization +and separation from legacy code. + +For complex screens that have specific components or data needs that _are not +shared by other screens_, we encourage subdirectories within `/screens/` +e.g. `/screens/ProfileScreen/ProfileScreen.tsx` and +`/screens/ProfileScreen/components/`. + +**Features** are higher-level modules that may include context, data fetching, +components, and utilities related to a specific feature e.g. +`/features/liveNow`. They don't neatly fit into components or screens and often +span multiple screens. This is an optional pattern for organizing complex +features. + +#### Legacy Directories + +For the most part, avoid writing new files into the `/view` directory and +subdirectories. This is the older pattern for organizing screens and components, +and it has become a bit disorganized over time. New development should go into +`/screens`, `/components`, and `/features`. + +#### State + +The `/state` directory is where we've historically put all our data fetching and +state management logic. This is perfectly fine, but for new features, consider +organizing state logic closer to the components that use it, either within a +feature directory or co-located with a screen. The key is to keep related code +together and avoid having "god files" with too much unrelated logic. + +#### Lib + +The `/lib` directory is for utilities and helpers that don't fit into other +categories. This can include things like API clients, formatting functions, +constants, and other shared logic. + +#### Top Level Directories + +Avoid writing new top-level subdirectories within `/src`. We've done this for a +few things in the past that, but we have stronger patterns now. Examples: +`/logger` should probably have been written into `/lib`. And `ageAssurance` is +better classified within `/features`. We will probably migrate these things +eventually. + +### File and Directory Naming Conventions + +Typically JS style for variables, functions, etc. We use ProudCamelCase for +components, and camelCase directories and files. + +For "macro" cases in `/features`, `/screens`, or `/components`, co-locate related +code in a directory with an `index.tsx` main component plus sibling +components/hooks/utils (e.g. `screens/ProfileScreen/index.tsx` + +`screens/ProfileScreen/components/`). Keep related code together so it lives where +someone would look for it. Don't overdo it: a component that fits in one file +should just be `Component.tsx`, not `Component/index.tsx`. + +Platform-specific files are covered under "Platform-Specific Code" below. + +### Comments + +Comment code when necessary to explain the “why” behind something; avoid +comments that simply describe the code. Avoid Unicode characters in comments, +e.g., use `-` not `—`. + +Always use docblock (`/** */`) syntax for comments that document a type, type +member, method, function, or variable. These are the comments a reader expects +to find attached to a named declaration, and the docblock form makes that intent +clear and surfaces nicely in editor tooltips. + +```tsx +type DateFieldProps = { + /** + * An empty string renders the placeholder and opens the picker at today (or + * maximumDate, if earlier). + */ + value: string | Date +} + +/** + * Date-only input. Accepts a string in the format YYYY-MM-DD, or a Date object. + */ +export function DateField() {} +``` + +More generally, any multiline comment should use the `/* */` block syntax rather +than stacked `//` lines. Reserve `//` for short, single-line comments. + +```tsx +/* + * The picker requires a valid date, so when value is empty we fall back to + * maximumDate (if set) or today. + */ +const fallbackDate = maximumDate ? toSimpleDateString(maximumDate) : today +``` + +### Documentation and Tests Within Features + +For larger features or components, co-locate documentation and tests with the +code. A `README.md` in the directory (the `/Component/index.tsx` pattern lends +itself well to this) can document the whole feature, and feature-specific tests +belong alongside it as `Component.test.tsx` or in a `__tests__/` subdirectory. +Both are optional. + +## Styling System (ALF) + +ALF is the custom design system. Tailwind-inspired naming with underscores +instead of hyphens. Static atoms (`atoms as a`) are theme-independent; theme +atoms/palette come from `useTheme()` (`t.atoms.bg`, `t.palette.primary_500`). +Style props take an array of atoms + theme atoms + raw styles. + +Order atoms by: flexbox (`a.flex_row`), spacing (`a.px_md`), text (`a.font_bold`), +themes (`t.atoms.text`), then raw styles (`{backgroundColor: t.palette.primary_500}`). + +```tsx +import {atoms as a, useTheme} from '#/alf' + +const t = useTheme() + +``` + +### Key Concepts + +Static atoms live in `a.*` (e.g. `a.flex_row`, `a.p_md`, `a.rounded_md`, +`a.text_lg`).

Refactor existing uses of ``_(msg`foo`)`` to use `` l`foo` ``. + +Prefer Unicode punctuation over keyboard punctuation, e.g., `“quote”` over `"quote"`.

The key root variable should match the hook name. +- Naming conventions: `use[Name]Query` for queries, `use[Name]Mutation` for + mutations, `use[Name]CacheMutation` for helpers that mutate cached data directly. +- Stale times come from `STALE` in `src/state/queries/index.ts`: `STALE.SECONDS.FIFTEEN`, + `STALE.MINUTES.ONE`, `STALE.MINUTES.FIVE`, `STALE.HOURS.ONE`, `STALE.INFINITY`. +- Paginated atproto APIs (those returning a `cursor`) use `useInfiniteQuery` with + `getNextPageParam: page => page.cursor`; flatten results with + `data?.pages.flatMap(page => page.items) ?? []`. +- Persist a query across restarts by passing options: + `createQueryKey(root, args, {persistedVersion: n})`. Bumping `n` clears the old + persisted data and refetches - do this whenever the data shape changes. +- Error handling in mutations: don't log network errors (just inform the user), + handle typed XRPC errors specifically (e.g. `err instanceof SomeNsid.SomeError`), + and send unexpected errors to `logger.error('...', {safeMessage: error})`. + +### Preferences (React Context) + +Boolean/simple UI preferences are exposed as paired hooks from `#/state/preferences`, +e.g. `useAutoplayDisabled()` / `useSetAutoplayDisabled()`. + +### Session State + +`import {useSession, useAgent} from '#/state/session'`. `useSession()` gives +`hasSession` and `currentAccount`; `useAgent()` gives the atproto agent for API calls. + +## Navigation + +React Navigation with type-safe route params. Type a screen with +`NativeStackScreenProps` (`route`/`navigation` come +from props; params via `route.params`). Navigate programmatically with +`useNavigation()`, or the `navigate` helper from `#/Navigation`. Config lives in +`src/Navigation.tsx`, routes in `src/routes.ts`, types in `src/lib/routes/types.ts`. + +## Platform-Specific Code + +Use file extensions for platform-specific implementations. The bundler resolves +them automatically - just import the base path normally, never a conditional +`require()`. + +``` +Component.tsx # Shared/default +Component.web.tsx # Web-only +Component.native.tsx # iOS + Android +Component.ios.tsx # iOS-only +Component.android.tsx # Android-only +``` + +Prefer grouping variants into a `Component/` directory (`index.tsx`, +`index.web.tsx`, `index.native.tsx`) rather than sibling `Component.web.tsx` files, +so the shared surface reads as one "macro" module (e.g. `src/components/Dialog/index.tsx` +native vs `index.web.tsx` web). The app has both patterns; the directory form is +preferred for new code. + +```tsx +// CORRECT - bundler picks storage.ts or storage.web.ts automatically +import * as storage from '#/state/drafts/storage' + +// WRONG - don't use require() or conditional imports for platform files +const storage = IS_NATIVE + ? require('#/state/drafts/storage') + : require('#/state/drafts/storage.web') +``` + +Runtime platform detection (not for imports): `import {IS_WEB, IS_NATIVE, IS_IOS, IS_ANDROID} from '#/env'`. + +## Import Aliases + +Always use the `#/` alias for absolute imports: + +```tsx +// Good +import {useSession} from '#/state/session' +import {atoms as a, useTheme} from '#/alf' +import {Button} from '#/components/Button' + +// Avoid +import {useSession} from '../../../state/session' +``` + +## Footguns + +Common pitfalls to avoid in this codebase: + +### Dialog Close Callback (Critical) + +**Always use `control.close(() => ...)` when performing actions after closing a dialog.** The callback ensures the action runs after the dialog's close animation completes.

Should be -platform-agnostic when possible. Examples: Button, Dialog, Menu, TextField. Put -these in `/components` if they are shared across screens. - -**Screens** are full-page components that represent a route in the app. They -often contain multiple components and handle layout for a page. New screens -should go in `/screens` (not `/view/screens`) to encourage better organization -and separation from legacy code. - -For complex screens that have specific components or data needs that _are not -shared by other screens_, we encourage subdirectories within `/screens/` -e.g. `/screens/ProfileScreen/ProfileScreen.tsx` and -`/screens/ProfileScreen/components/`. - -**Features** are higher-level modules that may include context, data fetching, -components, and utilities related to a specific feature e.g. -`/features/liveNow`. They don't neatly fit into components or screens and often -span multiple screens. This is an optional pattern for organizing complex -features. - -#### Legacy Directories - -For the most part, avoid writing new files into the `/view` directory and -subdirectories. This is the older pattern for organizing screens and components, -and it has become a bit disorganized over time. New development should go into -`/screens`, `/components`, and `/features`. - -#### State - -The `/state` directory is where we've historically put all our data fetching and -state management logic. This is perfectly fine, but for new features, consider -organizing state logic closer to the components that use it, either within a -feature directory or co-located with a screen. The key is to keep related code -together and avoid having "god files" with too much unrelated logic. - -#### Lib - -The `/lib` directory is for utilities and helpers that don't fit into other -categories. This can include things like API clients, formatting functions, -constants, and other shared logic. - -#### Top Level Directories - -Avoid writing new top-level subdirectories within `/src`. We've done this for a -few things in the past that, but we have stronger patterns now. Examples: -`/logger` should probably have been written into `/lib`. And `ageAssurance` is -better classified within `/features`. We will probably migrate these things -eventually. - -### File and Directory Naming Conventions - -Typically JS style for variables, functions, etc. We use ProudCamelCase for -components, and camelCase directories and files. - -For "macro" cases in `/features`, `/screens`, or `/components`, co-locate related -code in a directory with an `index.tsx` main component plus sibling -components/hooks/utils (e.g. `screens/ProfileScreen/index.tsx` + -`screens/ProfileScreen/components/`). Keep related code together so it lives where -someone would look for it. Don't overdo it: a component that fits in one file -should just be `Component.tsx`, not `Component/index.tsx`. - -Platform-specific files are covered under "Platform-Specific Code" below. - -### Comments - -Comment code when necessary to explain the “why” behind something; avoid -comments that simply describe the code. Avoid Unicode characters in comments, -e.g., use `-` not `—`. - -Always use docblock (`/** */`) syntax for comments that document a type, type -member, method, function, or variable. These are the comments a reader expects -to find attached to a named declaration, and the docblock form makes that intent -clear and surfaces nicely in editor tooltips. - -```tsx -type DateFieldProps = { - /** - * An empty string renders the placeholder and opens the picker at today (or - * maximumDate, if earlier). - */ - value: string | Date -} - -/** - * Date-only input. Accepts a string in the format YYYY-MM-DD, or a Date object. - */ -export function DateField() {} -``` - -More generally, any multiline comment should use the `/* */` block syntax rather -than stacked `//` lines. Reserve `//` for short, single-line comments. - -```tsx -/* - * The picker requires a valid date, so when value is empty we fall back to - * maximumDate (if set) or today. - */ -const fallbackDate = maximumDate ? toSimpleDateString(maximumDate) : today -``` - -### Documentation and Tests Within Features - -For larger features or components, co-locate documentation and tests with the -code. A `README.md` in the directory (the `/Component/index.tsx` pattern lends -itself well to this) can document the whole feature, and feature-specific tests -belong alongside it as `Component.test.tsx` or in a `__tests__/` subdirectory. -Both are optional. - -## Styling System (ALF) - -ALF is the custom design system. Tailwind-inspired naming with underscores -instead of hyphens. Static atoms (`atoms as a`) are theme-independent; theme -atoms/palette come from `useTheme()` (`t.atoms.bg`, `t.palette.primary_500`). -Style props take an array of atoms + theme atoms + raw styles. - -Order atoms by: flexbox (`a.flex_row`), spacing (`a.px_md`), text (`a.font_bold`), -themes (`t.atoms.text`), then raw styles (`{backgroundColor: t.palette.primary_500}`). - -```tsx -import {atoms as a, useTheme} from '#/alf' - -const t = useTheme() - -``` - -### Key Concepts - -Static atoms live in `a.*` (e.g. `a.flex_row`, `a.p_md`, `a.rounded_md`, -`a.text_lg`). Theme atoms/palette come from `useTheme()` (`t.atoms.bg`, -`t.atoms.text`, `t.atoms.border_contrast_low`, `t.palette.primary_500`). - -**Platform utilities** (`import {web, native, ios, android, platform} from '#/alf'`) -return conditional styles inline in a style array: `web({cursor: 'pointer'})`, -`native({paddingBottom: 20})`, `platform({ios: {...}, android: {...}, web: {...}})`. - -**Breakpoints:** `const {gtPhone, gtMobile, gtTablet} = useBreakpoints()` from `#/alf`. - -### Naming Conventions - -- Spacing: `2xs`, `xs`, `sm`, `md`, `lg`, `xl`, `2xl` (t-shirt sizes) -- Text: `text_xs`, `text_sm`, `text_md`, `text_lg`, `text_xl` -- Gaps/Padding: `gap_sm`, `p_md`, `px_lg`, `py_xl` -- Flex: `flex_row`, `flex_1`, `align_center`, `justify_between` -- Borders: `border`, `border_t`, `rounded_md`, `rounded_full` - -## Component Patterns - -- Prefer fragment shorthand over `Fragment` unless a `key` is needed. -- Prefer functions over arrow functions for component declarations. -- Prefer prop destructuring via parameters over a const within the component. -- Prefer inline types over `Props` types or interfaces. -- Set reasonable defaults for optional props. -- Prefer the implicit global `React` for types over `type` imports. - -```tsx -import {Fragment} from 'react' -import {View} from 'react-native' -import {Trans} from '@lingui/react/macro' - -import {Text} from '#/components/Typography' - -function MyComponent({ - items = [], - children, -}: { - items?: string[] - children: React.ReactNode -}) { - return ( - <> - - - Example - - - - {items.map((item, index) => ( - - {index} - {item} - - ))} - {children} - - - ) -} -``` - -### Dialog Component - -Lives in `#/components/Dialog`. Bottom sheet on native, modal on web. Manage -state with `useDialogControl()`. `Dialog.Handle` renders native-only, `Dialog.Close` -web-only. CRITICAL: run any post-close action inside the `control.close(() => ...)` -callback (see Footguns). Compound-component usage; canonical example in any dialog -under `#/components`. - -### Menu Component - -Lives in `#/components/Menu`. Dropdown on web, bottom sheet dialog on native. -`Menu.Divider` is web-only, `Menu.ContainerItem` native-only. Compound API -(`Menu.Root` / `Menu.Trigger` / `Menu.Outer` / `Menu.Group` / `Menu.Item`); grep -existing usages across the app for a canonical example. - -### Button Component - -`import {Button, ButtonText, ButtonIcon} from '#/components/Button'`. Props: - -- `color`: `'primary'` | `'secondary'` | `'negative'` | `'primary_subtle'` | `'negative_subtle'` | `'secondary_inverted'` -- `size`: `'tiny'` | `'small'` | `'large'` -- `shape`: `'default'` (pill) | `'round'` | `'square'` | `'rectangular'` -- `variant`: `'solid'` | `'outline'` | `'ghost'` (deprecated, prefer `color`) - -### TextField - -Compound component at `#/components/forms/TextField` (`TextField.LabelText`, -`TextField.Root`, `TextField.Icon`, `TextField.Input`). Prefer `defaultValue` over -`value` (see Footguns). - -### Typography - -`import {Text, H1, H2, P} from '#/components/Typography'`. The `Text` default style -is `[a.text_sm, a.leading_snug, t.atoms.text]`. Pass the `emoji` prop to any `Text` -that may contain emoji - user-generated text (display names etc.) almost always -does, so only omit it for static, emoji-free strings: `Hello!`. - -## Internationalization (i18n) - -All user-facing strings must be wrapped for translation using Lingui. Include `comment` and/or `context` props when necessary to avoid ambiguity, e.g., “Post” as a noun vs a verb. - -Prefer using `t` via `import {useLingui} '@lingui/react/macro'` vs `_` via `import {useLingui} from '@lingui/react'`. Alias `t` to `l` to avoid collisions with `const t = useTheme()`. Refactor existing uses of ``_(msg`foo`)`` to use `` l`foo` ``. - -Prefer Unicode punctuation over keyboard punctuation, e.g., `“quote”` over `"quote"`. Prefer en dashes preceded by a non-breaking space over em dashes, e.g., `one – two` over `one—two`. - -```tsx -import {plural} from '@lingui/core/macro' -import {Trans, useLingui} from '@lingui/react/macro' - -function MyComponent() { - const {t: l} = useLingui() - - // Simple strings - use the l macro - const title = l`Settings` - const errorMessage = l({ - message: 'Something went wrong', - comment: 'Generic error message for unknown/unhandled errors.', - context: 'Toast', - }) - - // Strings with variables - const greeting = l`Hello, ${name}!` - - // Pluralization - const countLabel = plural(count, { - one: '# item', - other: '# items', - }) - - // JSX content - use Trans component - return ( - - - Welcome to Bluesky, {name}! - - - ) -} -``` - -Prefer `i18n.date` for date and time formatting. This ensures formatting is re-applied when the language changes at runtime. Refactor existing uses of `Intl.DateTimeFormat` to use `i18n.date`. - -```tsx -import {useLingui} from '@lingui/react/macro' - -function MyComponent() { - const {i18n} = useLingui() - - const createdAt = new Date() - - return i18n.date(createdAt, { - dateStyle: 'medium', - timeStyle: 'medium', - }) -} -``` - -**Commands:** - -```bash -# DO NOT run these commands - extraction and compilation are handled by a nightly CI job -pnpm intl:extract # Extract new strings to locale files -pnpm intl:compile # Compile translations for runtime -``` - -## State Management - -### TanStack Query (Data Fetching) - -Follow the established pattern in `src/state/queries/`; `src/state/queries/feed.ts` -is a good canonical reference (it uses `createQueryKey`, matching key roots, -`useInfiniteQuery`, and `persistedVersion`). - -- Build query keys with `createQueryKey(root, args)` (from `#/state/queries/util`) - using an object for `args`. The key root variable should match the hook name. -- Naming conventions: `use[Name]Query` for queries, `use[Name]Mutation` for - mutations, `use[Name]CacheMutation` for helpers that mutate cached data directly. -- Stale times come from `STALE` in `src/state/queries/index.ts`: `STALE.SECONDS.FIFTEEN`, - `STALE.MINUTES.ONE`, `STALE.MINUTES.FIVE`, `STALE.HOURS.ONE`, `STALE.INFINITY`. -- Paginated atproto APIs (those returning a `cursor`) use `useInfiniteQuery` with - `getNextPageParam: page => page.cursor`; flatten results with - `data?.pages.flatMap(page => page.items) ?? []`. -- Persist a query across restarts by passing options: - `createQueryKey(root, args, {persistedVersion: n})`. Bumping `n` clears the old - persisted data and refetches - do this whenever the data shape changes. -- Error handling in mutations: don't log network errors (just inform the user), - handle typed XRPC errors specifically (e.g. `err instanceof SomeNsid.SomeError`), - and send unexpected errors to `logger.error('...', {safeMessage: error})`. - -### Preferences (React Context) - -Boolean/simple UI preferences are exposed as paired hooks from `#/state/preferences`, -e.g. `useAutoplayDisabled()` / `useSetAutoplayDisabled()`. - -### Session State - -`import {useSession, useAgent} from '#/state/session'`. `useSession()` gives -`hasSession` and `currentAccount`; `useAgent()` gives the atproto agent for API calls. - -## Navigation - -React Navigation with type-safe route params. Type a screen with -`NativeStackScreenProps` (`route`/`navigation` come -from props; params via `route.params`). Navigate programmatically with -`useNavigation()`, or the `navigate` helper from `#/Navigation`. Config lives in -`src/Navigation.tsx`, routes in `src/routes.ts`, types in `src/lib/routes/types.ts`. - -## Platform-Specific Code - -Use file extensions for platform-specific implementations. The bundler resolves -them automatically - just import the base path normally, never a conditional -`require()`. - -``` -Component.tsx # Shared/default -Component.web.tsx # Web-only -Component.native.tsx # iOS + Android -Component.ios.tsx # iOS-only -Component.android.tsx # Android-only -``` - -Prefer grouping variants into a `Component/` directory (`index.tsx`, -`index.web.tsx`, `index.native.tsx`) rather than sibling `Component.web.tsx` files, -so the shared surface reads as one "macro" module (e.g. `src/components/Dialog/index.tsx` -native vs `index.web.tsx` web). The app has both patterns; the directory form is -preferred for new code. - -```tsx -// CORRECT - bundler picks storage.ts or storage.web.ts automatically -import * as storage from '#/state/drafts/storage' - -// WRONG - don't use require() or conditional imports for platform files -const storage = IS_NATIVE - ? require('#/state/drafts/storage') - : require('#/state/drafts/storage.web') -``` - -Runtime platform detection (not for imports): `import {IS_WEB, IS_NATIVE, IS_IOS, IS_ANDROID} from '#/env'`. - -## Import Aliases - -Always use the `#/` alias for absolute imports: - -```tsx -// Good -import {useSession} from '#/state/session' -import {atoms as a, useTheme} from '#/alf' -import {Button} from '#/components/Button' - -// Avoid -import {useSession} from '../../../state/session' -``` - -## Footguns - -Common pitfalls to avoid in this codebase: - -### Dialog Close Callback (Critical) - -**Always use `control.close(() => ...)` when performing actions after closing a dialog.** The callback ensures the action runs after the dialog's close animation completes. Failing to do this causes race conditions with React state updates. - -```tsx -// WRONG - causes bugs with state updates, navigation, opening other dialogs -const onConfirm = () => { - control.close() - navigation.navigate('Home') // May race with dialog animation -} - -// WRONG - same problem -const onConfirm = () => { - control.close() - otherDialogControl.open() // Will likely fail or cause visual glitches -} - -// CORRECT - action runs after dialog fully closes -const onConfirm = () => { - control.close(() => { - navigation.navigate('Home') - }) -} - -// CORRECT - opening another dialog after close -const onConfirm = () => { - control.close(() => { - otherDialogControl.open() - }) -} - -// CORRECT - state updates after close -const onConfirm = () => { - control.close(() => { - setSomeState(newValue) - onCallback?.() - }) -} -``` - -This applies to: - -- Navigation (`navigation.navigate()`, `navigation.push()`) -- Opening other dialogs or menus -- State updates that affect UI (`setState`, `queryClient.invalidateQueries`) -- Callbacks passed from parent components - -The Menu component on iOS specifically uses this pattern – see `src/components/Menu/index.tsx:151`. - -### Controlled vs Uncontrolled Inputs - -Prefer `defaultValue` over `value` for TextInput on the old architecture: - -```tsx -// Preferred - uncontrolled - - -// Avoid when possible - controlled (can cause performance issues) - -``` - -### Platform-Specific Behavior - -Some components behave differently across platforms: - -- `Dialog.Handle` – Only renders on native (drag handle for bottom sheet) -- `Dialog.Close` – Only renders on web (X button) -- `Menu.Divider` – Only renders on web -- `Menu.ContainerItem` – Only works on native - -Always test on multiple platforms when using these components. - -### React Compiler is Enabled - -This codebase uses React Compiler, so **don't proactively add `useMemo` or `useCallback`**. The compiler handles memoization automatically. - -```tsx -// UNNECESSARY - React Compiler handles this -const handlePress = useCallback(() => { - doSomething() -}, [doSomething]) - -// JUST WRITE THIS -const handlePress = () => { - doSomething() -} -``` - -Only use `useMemo`/`useCallback` when you have a specific reason, such as: - -- The value is immediately used in an effect's dependency array -- You're passing a callback to a non-React library that needs referential stability - -## Best Practices - -1. **Accessibility**: Always provide `label` prop for interactive elements, use `accessibilityHint` where helpful - -2. **Translations**: Wrap ALL user-facing strings with the `` l`…` `` macro or the `` component - -3. **Styling**: Combine static atoms with theme atoms, use platform utilities for platform-specific styles - -4. **State**: Use TanStack Query for server state, React Context for UI preferences - -5. **Components**: Check if a component exists in `#/components/` before creating new ones - -6. **Types**: Define explicit types for props, use `NativeStackScreenProps` for screens - -7. **Testing**: Components should have `testID` props for E2E testing - -## Key Files Reference - -| Purpose | Location | -| ----------------- | -------------------------------------------- | -| Theme definitions | `src/alf/themes.ts` | -| Design tokens | `src/alf/tokens.ts` | -| Static atoms | `src/alf/atoms.ts` (extends `@bsky.app/alf`) | -| Navigation config | `src/Navigation.tsx` | -| Route definitions | `src/routes.ts` | -| Route types | `src/lib/routes/types.ts` | -| Query hooks | `src/state/queries/*.ts` | -| Session state | `src/state/session/index.tsx` | -| i18n setup | `src/locale/i18n.ts` | +@AGENTS.md diff --git a/src/features/inviteFriends/InviteFriendsDialogInner.tsx b/src/features/inviteFriends/InviteFriendsDialogInner.tsx index c29aef39fd..de0ef009c9 100644 --- a/src/features/inviteFriends/InviteFriendsDialogInner.tsx +++ b/src/features/inviteFriends/InviteFriendsDialogInner.tsx @@ -112,8 +112,6 @@ export function InviteFriendsDialogInner({ const onScan = () => { ax.metric('invite:action:scan', {}) - // Close dialog first, then navigate (control.close callback per CLAUDE.md - // Dialog footgun rule — prevents race with the navigation push). control.close(() => { navigation.navigate('InviteScanner') })
