+# Authentication Setup Guide
+
+This document explains the authentication system that has been set up for your Laravel + Inertia.js + Vue 3 application.
+
+## 📦 What Was Installed/Created
+
+### Files Created:
+1. **`resources/js/services/authService.ts`** - API service for authentication
+2. **`resources/js/stores/auth.ts`** - Pinia store for auth state management
+3. **`resources/js/middleware/auth.ts`** - Route guards for authentication
+4. **`resources/js/composables/useAuthGuard.ts`** - Composables for protecting routes
+5. **`resources/js/components/LoginExample.vue`** - Example login component
+
+### Files Modified:
+- **`resources/js/app.ts`** - Integrated auth guards
+
+## 🔧 Setup
+
+### Note: Pinia instead of Vuex
+Your project already has **Pinia** installed, which is the official state management solution for Vue 3 (and the successor to Vuex). The setup uses Pinia instead of Vuex as requested.
+
+If you specifically need Vuex 4, run:
+```bash
+npm install vuex@4
+```
+
+However, Pinia is recommended for Vue 3 projects.
+
+## 🚀 Usage
+
+### 1. Using the Auth Store
+
+The auth store provides all authentication functionality:
+
+```vue
+<script setup lang="ts">
+import { useAuthStore } from '@/stores/auth';
+
+const authStore = useAuthStore();
+
+// Login
+async function login() {
+    const success = await authStore.login({
+        email: 'user@example.com',
+        password: 'password',
+        remember: true
+    });
+    
+    if (success) {
+        // Redirect or show success message
+    } else {
+        console.error(authStore.error);
+    }
+}
+
+// Logout
+async function logout() {
+    await authStore.logout();
+}
+
+// Check authentication status
+console.log(authStore.isAuthenticated);
+console.log(authStore.currentUser);
+</script>
+```
+
+### 2. Protecting Routes with Composables
+
+#### Protect authenticated routes (dashboard, profile, etc.):
+
+```vue
+<script setup lang="ts">
+import { useAuthGuard } from '@/composables/useAuthGuard';
+
+// This will redirect to /login if user is not authenticated
+useAuthGuard();
+</script>
+
+<template>
+    <div>
+        <h1>Protected Dashboard</h1>
+    </div>
+</template>
+```
+
+#### Protect guest routes (login, register):
+
+```vue
+<script setup lang="ts">
+import { useGuestGuard } from '@/composables/useAuthGuard';
+
+// This will redirect to /dashboard if user is already authenticated
+useGuestGuard();
+</script>
+
+<template>
+    <div>
+        <h1>Login Page</h1>
+    </div>
+</template>
+```
+
+### 3. Accessing User Data
+
+```vue
+<script setup lang="ts">
+import { useAuthStore } from '@/stores/auth';
+
+const authStore = useAuthStore();
+</script>
+
+<template>
+    <div v-if="authStore.isAuthenticated">
+        <p>Welcome, {{ authStore.currentUser?.name }}!</p>
+        <p>Email: {{ authStore.currentUser?.email }}</p>
+        <button @click="authStore.logout">Logout</button>
+    </div>
+    <div v-else>
+        <p>Please log in</p>
+    </div>
+</template>
+```
+
+### 4. Auth Store API
+
+The auth store (`useAuthStore()`) provides:
+
+**State:**
+- `user` - Current user object or null
+- `token` - Authentication token (if API returns one)
+- `loading` - Loading state
+- `error` - Error message
+
+**Getters:**
+- `isAuthenticated` - Boolean indicating if user is logged in
+- `currentUser` - Current user object
+
+**Actions:**
+- `login(credentials)` - Login with email and password
+- `logout()` - Logout current user
+- `checkAuth()` - Check if user is authenticated
+- `fetchUser()` - Fetch current user data
+- `clearError()` - Clear error messages
+- `setUser(user)` - Manually set user data
+
+## 🔐 API Endpoints
+
+The auth service expects these endpoints:
+
+### Login
+```
+POST http://localhost:8000/api/auth/login
+Body: {
+    "email": "user@example.com",
+    "password": "password",
+    "remember": true
+}
+
+Response: {
+    "user": {
+        "id": 1,
+        "name": "John Doe",
+        "email": "user@example.com",
+        ...
+    },
+    "token": "optional-auth-token"
+}
+```
+
+### Logout
+```
+POST http://localhost:8000/api/auth/logout
+```
+
+### Get Current User
+```
+GET http://localhost:8000/api/auth/user
+
+Response: {
+    "user": {
+        "id": 1,
+        "name": "John Doe",
+        "email": "user@example.com",
+        ...
+    }
+}
+```
+
+## 🛠️ Backend Setup (Laravel)
+
+You need to create these API routes in Laravel. Here's an example:
+
+```php
+// routes/api.php
+use App\Http\Controllers\Auth\ApiAuthController;
+
+Route::prefix('auth')->group(function () {
+    Route::post('/login', [ApiAuthController::class, 'login']);
+    Route::post('/logout', [ApiAuthController::class, 'logout'])->middleware('auth:sanctum');
+    Route::get('/user', [ApiAuthController::class, 'user'])->middleware('auth:sanctum');
+});
+```
+
+Example controller:
+
+```php
+// app/Http/Controllers/Auth/ApiAuthController.php
+namespace App\Http\Controllers\Auth;
+
+use App\Http\Controllers\Controller;
+use Illuminate\Http\Request;
+use Illuminate\Support\Facades\Auth;
+
+class ApiAuthController extends Controller
+{
+    public function login(Request $request)
+    {
+        $credentials = $request->validate([
+            'email' => 'required|email',
+            'password' => 'required',
+        ]);
+
+        if (Auth::attempt($credentials, $request->boolean('remember'))) {
+            $user = Auth::user();
+            $token = $user->createToken('auth-token')->plainTextToken;
+
+            return response()->json([
+                'user' => $user,
+                'token' => $token,
+            ]);
+        }
+
+        return response()->json([
+            'message' => 'Invalid credentials',
+        ], 401);
+    }
+
+    public function logout(Request $request)
+    {
+        $request->user()->currentAccessToken()->delete();
+        return response()->json(['message' => 'Logged out successfully']);
+    }
+
+    public function user(Request $request)
+    {
+        return response()->json(['user' => $request->user()]);
+    }
+}
+```
+
+## 💾 Persistence
+
+The auth store automatically persists the `user` and `token` to localStorage using `pinia-plugin-persistedstate`. This means:
+- User stays logged in after page refresh
+- Auth state is restored on app load
+- Logout clears the persisted data
+
+## 🎯 Example: Update Your Login Page
+
+Update your existing `resources/js/pages/auth/Login.vue`:
+
+```vue
+<script setup lang="ts">
+import { useAuthStore } from '@/stores/auth';
+import { useGuestGuard } from '@/composables/useAuthGuard';
+import { router } from '@inertiajs/vue3';
+import { ref } from 'vue';
+
+// Redirect if already authenticated
+useGuestGuard();
+
+const authStore = useAuthStore();
+const email = ref('');
+const password = ref('');
+const remember = ref(false);
+
+async function handleLogin() {
+    const success = await authStore.login({
+        email: email.value,
+        password: password.value,
+        remember: remember.value,
+    });
+
+    if (success) {
+        router.get('/dashboard');
+    }
+}
+</script>
+```
+
+## 🎯 Example: Protect Dashboard
+
+Update your dashboard to require authentication:
+
+```vue
+<script setup lang="ts">
+import { useAuthGuard } from '@/composables/useAuthGuard';
+
+// This will redirect to login if not authenticated
+useAuthGuard();
+</script>
+
+<template>
+    <div>
+        <h1>Dashboard</h1>
+        <!-- Your dashboard content -->
+    </div>
+</template>
+```
+
+## 📝 Notes
+
+1. **Axios is already installed** in your project at version `1.11.0`
+2. **Pinia is already installed** and configured with persistence
+3. The auth system works with your existing Inertia.js setup
+4. CSRF tokens are automatically handled via the existing `resources/js/lib/http.ts`
+5. Authentication state persists across page reloads
+
+## 🔄 Customization
+
+### Change API URLs
+Edit `resources/js/services/authService.ts` to change the API endpoints.
+
+### Change Redirect Routes
+Edit the composables in `resources/js/composables/useAuthGuard.ts` to change default redirect routes.
+
+### Add More User Fields
+Update the `User` interface in `resources/js/services/authService.ts` to match your user model.

+# 🚀 Quick Start - Authentication System
+
+## ✅ What's Been Set Up
+
+Your Laravel + Vue 3 + Inertia.js application now has a complete authentication system with:
+
+1. ✅ **Axios** - Already installed (v1.11.0)
+2. ✅ **Pinia** - State management (already installed, replaces Vuex)
+3. ✅ **Auth Service** - API calls to `http://localhost:8000/api/auth/login`
+4. ✅ **Auth Store** - Centralized authentication state
+5. ✅ **Route Guards** - Protect pages based on authentication
+6. ✅ **Persistence** - Auth state survives page reloads

+
+## 🎯 How to Use
+
+### 1. In Your Login Component
+
+```vue
+<script setup lang="ts">
+import { useAuthStore } from '@/stores/auth';
+import { router } from '@inertiajs/vue3';
+import { ref } from 'vue';
+
+const authStore = useAuthStore();
+const email = ref('');
+const password = ref('');
+
+async function login() {
+    const success = await authStore.login({
+        email: email.value,
+        password: password.value,
+        remember: true
+    });
+    
+    if (success) {
+        router.get('/dashboard');
+    }
+}
+</script>
+
+<template>
+    <form @submit.prevent="login">
+        <input v-model="email" type="email" placeholder="Email" />
+        <input v-model="password" type="password" placeholder="Password" />
+        <button type="submit" :disabled="authStore.loading">
+            {{ authStore.loading ? 'Logging in...' : 'Login' }}
+        </button>
+        <p v-if="authStore.error" class="error">{{ authStore.error }}</p>
+    </form>
+</template>
+```
+
+### 2. Protect Your Dashboard
+
+```vue
+<script setup lang="ts">
+import { useAuthGuard } from '@/composables/useAuthGuard';
+
+// This will redirect to /login if not authenticated
+useAuthGuard();
+</script>
+
+<template>
+    <div>
+        <h1>Protected Dashboard</h1>
+    </div>
+</template>
+```
+
+### 3. Display User Info
+
+```vue
+<script setup lang="ts">
+import { useAuthStore } from '@/stores/auth';
+
+const authStore = useAuthStore();
+</script>
+
+<template>
+    <div v-if="authStore.isAuthenticated">
+        Welcome, {{ authStore.currentUser?.name }}!
+        <button @click="authStore.logout">Logout</button>
+    </div>
+</template>
+```
+
+## 🔧 Backend Requirements
+
+You need these Laravel API endpoints:
+
+### Login Endpoint
+```php
+// POST http://localhost:8000/api/auth/login
+Route::post('api/auth/login', function(Request $request) {
+    $credentials = $request->validate([
+        'email' => 'required|email',
+        'password' => 'required',
+    ]);
+
+    if (Auth::attempt($credentials)) {
+        return response()->json([
+            'user' => Auth::user(),
+            'token' => Auth::user()->createToken('auth')->plainTextToken
+        ]);
+    }
+
+    return response()->json(['message' => 'Invalid credentials'], 401);
+});
+```
+
+### User Endpoint
+```php
+// GET http://localhost:8000/api/auth/user
+Route::get('api/auth/user', function() {
+    return response()->json(['user' => Auth::user()]);
+})->middleware('auth:sanctum');
+```
+
+### Logout Endpoint
+```php
+// POST http://localhost:8000/api/auth/logout
+Route::post('api/auth/logout', function(Request $request) {
+    $request->user()->currentAccessToken()->delete();
+    return response()->json(['message' => 'Logged out']);
+})->middleware('auth:sanctum');
+```
+
+## 🎨 Complete Working Examples
+
+### Example 1: Simple Login Page
+
+```vue
+<script setup lang="ts">
+import { useAuthStore } from '@/stores/auth';
+import { useGuestGuard } from '@/composables/useAuthGuard';
+import { router } from '@inertiajs/vue3';
+import { ref } from 'vue';
+
+useGuestGuard(); // Redirect to dashboard if already logged in
+
+const authStore = useAuthStore();
+const form = ref({
+    email: '',
+    password: '',
+    remember: false
+});
+
+async function handleSubmit() {
+    const success = await authStore.login(form.value);
+    if (success) {
+        router.get('/dashboard');
+    }
+}
+</script>
+
+<template>
+    <div class="login-container">
+        <h1>Login</h1>
+        
+        <div v-if="authStore.error" class="alert alert-error">
+            {{ authStore.error }}
+        </div>
+
+        <form @submit.prevent="handleSubmit">
+            <div>
+                <label>Email</label>
+                <input v-model="form.email" type="email" required />
+            </div>
+
+            <div>
+                <label>Password</label>
+                <input v-model="form.password" type="password" required />
+            </div>
+
+            <div>
+                <label>
+                    <input v-model="form.remember" type="checkbox" />
+                    Remember me
+                </label>
+            </div>
+
+            <button type="submit" :disabled="authStore.loading">
+                {{ authStore.loading ? 'Logging in...' : 'Login' }}
+            </button>
+        </form>
+    </div>
+</template>
+```
+
+### Example 2: Protected Dashboard
+
+```vue
+<script setup lang="ts">
+import { useAuthGuard } from '@/composables/useAuthGuard';
+import { useAuthStore } from '@/stores/auth';
+import { router } from '@inertiajs/vue3';
+
+useAuthGuard(); // Redirect to login if not authenticated
+
+const authStore = useAuthStore();
+
+async function handleLogout() {
+    await authStore.logout();
+    router.get('/login');
+}
+</script>
+
+<template>
+    <div class="dashboard">
+        <header>
+            <h1>Dashboard</h1>
+            <div class="user-menu">
+                <span>{{ authStore.currentUser?.name }}</span>
+                <button @click="handleLogout">Logout</button>
+            </div>
+        </header>
+        
+        <main>
+            <p>Welcome back, {{ authStore.currentUser?.name }}!</p>
+            <p>Email: {{ authStore.currentUser?.email }}</p>
+        </main>
+    </div>
+</template>
+```
+
+## 📋 Auth Store API Reference
+
+```typescript
+const authStore = useAuthStore();
+
+// State
+authStore.user              // User object or null
+authStore.token             // Auth token or null
+authStore.loading           // Boolean: loading state
+authStore.error             // String: error message or null
+
+// Getters
+authStore.isAuthenticated   // Boolean: is user logged in?
+authStore.currentUser       // User object or null
+
+// Actions
+await authStore.login({ email, password, remember })   // Returns boolean
+await authStore.logout()                               // Returns void
+await authStore.checkAuth()                            // Returns boolean
+await authStore.fetchUser()                            // Returns void
+authStore.clearError()                                 // Returns void
+authStore.setUser(userData)                            // Returns void
+```
+
+## ✨ Key Features
+
+- ✅ **Auto-persistence**: Auth state saved to localStorage
+- ✅ **CSRF Protection**: Automatically handled
+- ✅ **Error Handling**: Built-in error messages
+- ✅ **Loading States**: Track async operations
+- ✅ **TypeScript**: Full type safety
+- ✅ **Inertia Compatible**: Works with your existing setup
+
+## 🐛 Troubleshooting
+
+### Issue: User not staying logged in
+**Solution**: Make sure your Laravel API returns the user object on the `/api/auth/user` endpoint
+
+### Issue: CSRF token mismatch
+**Solution**: Your existing `resources/js/lib/http.ts` handles this automatically
+
+### Issue: Redirect not working
+**Solution**: Ensure you're using `router.get()` from `@inertiajs/vue3`
+
+## 📚 Next Steps
+
+1. Create your Laravel API endpoints (see examples above)
+2. Update your login page component
+3. Add `useAuthGuard()` to protected pages
+4. Test the authentication flow
