frontend/tsconfig.json (1)

11-11: Consider scoping include to frontend sources (or add exclude) to avoid accidental typechecking noise.
"include": ["**/*.ts", "**/*.tsx", ...] is fine if this tsconfig.json is only used from the frontend/ directory, but it can also pull in tooling/generated TS and create surprising type errors. A common pattern is include: ["app/**/*", "components/**/*", "hooks/**/*", "constants/**/*", ...] or keeping broad includes but adding an exclude for things like dist, build, node_modules, etc.

Also please confirm that any imports expecting hono/client.mts types still resolve correctly after removing its explicit inclusion (hono v4.10.8). If you want, I can propose a concrete include/exclude diff once you confirm what TS folders exist under frontend/.

frontend/.env.sample (1)

1-2: Remove quotes and add ending newline.

The empty quotes around the values are unnecessary and can be confusing. Additionally, the file is missing a trailing newline.

frontend/services/users/current-user-hooks.ts (1)

1-1: Empty hook implementation with missing return type.

This hook has no implementation and no explicit return type. Per coding guidelines, exported functions should have explicit return types. Consider implementing this hook to consume useAuthContext() from auth-provider.tsx, or remove it if not needed in this PR.

-export function useCurrentUser() {}
+import { useAuthContext } from '@/components/providers/auth-provider'
+import type { AuthData } from '@/entities/auth/session'
+
+export function useCurrentUser(): AuthData {
+  return useAuthContext()
+}

frontend/app/register.tsx (1)

11-17: Missing explicit return type on exported component.

Per coding guidelines, prefer explicit return types on exported functions and components.

-export default function RegisterScreen() {
+export default function RegisterScreen(): React.JSX.Element {

frontend/app/_layout.tsx (1)

34-46: Consider adding register route to Stack for consistency.

The login route is explicitly declared but register is not, even though both are public routes in AuthProvider. While Expo Router auto-discovers routes, explicit declaration ensures consistent behavior.

        <Stack screenOptions={{ headerShown: false }}>
          <Stack.Screen name="login" />
+          <Stack.Screen name="register" />
          <Stack.Screen name="index" />
          <Stack.Screen
            name="modal"
            options={{ presentation: 'modal', title: 'Modal' }}
          />
        </Stack>

frontend/services/auth/signup.ts (1)

77-82: Consider trimming displayName before sending to backend.

Email and password are trimmed before submission, but displayName is not. For consistency, trim it as well.

        await createUser({
          userId: user.id,
-          displayName: values.displayName,
+          displayName: values.displayName.trim(),
          accessToken,
        })

frontend/components/providers/auth-provider.tsx (3)

24-24: Missing explicit return type on exported component.

Per coding guidelines, prefer explicit return types on exported functions.

-export default function AuthProvider({ children }: PropsWithChildren) {
+export default function AuthProvider({ children }: PropsWithChildren): React.JSX.Element {

---

46-49: Consider extracting publicRoutes outside the component.

The publicRoutes array is recreated on every render. Moving it outside the component avoids unnecessary allocations.

+const PUBLIC_ROUTES = ['login', 'register']
+
 export default function AuthProvider({ children }: PropsWithChildren) {
   // ...
-  const publicRoutes = ['login', 'register']
-  const currentRoute = segments[0]
-  const isPublicRoute = publicRoutes.includes(currentRoute || '')
+  const currentRoute = segments[0]
+  const isPublicRoute = PUBLIC_ROUTES.includes(currentRoute || '')

---

38-44: Loading state could benefit from better UX.

Plain text "読み込み中..." may not provide the best user experience. Consider using a centered spinner or skeleton screen for a more polished loading state.

frontend/services/auth/session.ts (1)

28-32: Consider adding isMounted check in onAuthStateChange callback.

The onAuthStateChange callback could potentially fire between the cleanup function setting isMounted = false and unsubscribe() completing, leading to a state update on an unmounted component.

    const { data: subscription } = supabase.auth.onAuthStateChange(
      (_event, nextSession) => {
+        if (!isMounted) return
        setSession(nextSession)
      }
    )

frontend/app/login.tsx (2)

36-40: Password should be trimmed for consistency.

Email is trimmed but password is not. Apply the same trimming for consistency with the signup flow.

        const { error } = await supabase.auth.signInWithPassword({
          email: email.trim(),
-          password,
+          password: password.trim(),
        })

---

12-16: Missing explicit return type on exported components.

38-44: Consider a more polished loading indicator.

Example:

import { ActivityIndicator, View } from 'react-native'

if (isLoading) {
  return (
    <AuthContext.Provider value={value}>
      <View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
        <ActivityIndicator size="large" />
      </View>
    </AuthContext.Provider>

For consistency and better type safety, consider adding an explicit return type annotation to the createUser function.

Apply this diff:

-  const createUser = async (
-    args: CreateUserArgs
-  ): Promise<createUserResponse> => {
+  const createUser = async (args: CreateUserArgs): Promise<createUserResponse> => {

Note: The return type is already annotated; this is just a formatting suggestion to keep it on one line if preferred.

frontend/services/auth/signup.ts (1)

35-40: Redundant trim() in validation schema and submission.

The Yup.string().trim() in the validation schema (lines 35, 37, 40) already transforms the values. Calling .trim() again in the onSubmit handler (lines 50-51) is redundant.

You can remove the .trim() calls in onSubmit:

         } = await supabase.auth.signUp({
-          email: values.email.trim(),
-          password: values.password.trim(),
+          email: values.email,
+          password: values.password,
         })

Yup's trim() already normalizes the values before they reach onSubmit.

frontend/services/auth/session.ts (1)

23-31: Fix the confusing destructuring pattern for onAuthStateChange subscription.

The current pattern const { data: subscription } assigns the entire data object to subscription, then accesses subscription.subscription.unsubscribe(). While technically functional, this is confusing. Use nested destructuring for clarity:

-    const { data: subscription } = supabase.auth.onAuthStateChange(
+    const { data: { subscription } } = supabase.auth.onAuthStateChange(
       (_event, nextSession) => {
         mutate(nextSession ?? null, false)
