# Laravel + Inertia.js + React

Comprehensive patterns for building modern monolithic applications with Laravel, Inertia.js, and React. Contains 30+ rules for seamless full-stack development.

## When to Apply

Reference these guidelines when:
- Creating Inertia page components
- Handling forms with useForm hook
- Managing shared data and authentication
- Implementing persistent layouts
- Navigating between pages

## Rule Categories by Priority

| Priority | Category | Impact | Prefix |
|----------|----------|--------|--------|
| 1 | Page Components | CRITICAL | `page-` |
| 2 | Forms & Validation | CRITICAL | `form-` |
| 3 | Navigation & Links | HIGH | `nav-` |
| 4 | Shared Data | HIGH | `shared-` |
| 5 | Layouts | MEDIUM | `layout-` |
| 6 | File Uploads | MEDIUM | `upload-` |
| 7 | Advanced Patterns | LOW | `advanced-` |

## Quick Reference

### 1. Page Components (CRITICAL)

- `page-props-typing` - Type page props from Laravel
- `page-component-structure` - Standard page component pattern
- `page-head-management` - Title and meta tags with Head
- `page-default-layout` - Assign layouts to pages

### 2. Forms & Validation (CRITICAL)

- `form-useform-basic` - Basic useForm usage
- `form-validation-errors` - Display Laravel validation errors
- `form-processing-state` - Handle form submission state
- `form-reset-preserve` - Reset vs preserve form data
- `form-nested-data` - Handle nested form data
- `form-transform` - Transform data before submit

### 3. Navigation & Links (HIGH)

- `nav-link-component` - Use Link for navigation
- `nav-preserve-state` - Preserve scroll and state
- `nav-partial-reloads` - Reload only what changed
- `nav-replace-history` - Replace vs push history

### 4. Shared Data (HIGH)

- `shared-auth-user` - Access authenticated user
- `shared-flash-messages` - Handle flash messages
- `shared-global-props` - Access global props
- `shared-typescript` - Type shared data

### 5. Layouts (MEDIUM)

- `layout-persistent` - Persistent layouts pattern
- `layout-nested` - Nested layouts
- `layout-default` - Default layout assignment
- `layout-conditional` - Conditional layouts

### 6. File Uploads (MEDIUM)

- `upload-basic` - Basic file upload
- `upload-progress` - Upload progress tracking
- `upload-multiple` - Multiple file uploads

### 7. Advanced Patterns (LOW)

- `advanced-polling` - Real-time polling
- `advanced-prefetch` - Prefetch pages
- `advanced-modal-pages` - Modal as pages
- `advanced-infinite-scroll` - Infinite scrolling

## Essential Patterns

### Page Component with TypeScript

```tsx
// resources/js/Pages/Posts/Index.tsx
import { Head, Link } from '@inertiajs/react'

interface Post {
  id: number
  title: string
  excerpt: string
  created_at: string
  author: {
    id: number
    name: string
  }
}

interface Props {
  posts: {
    data: Post[]
    links: { url: string | null; label: string; active: boolean }[]
  }
  filters: {
    search?: string
  }
}

export default function Index({ posts, filters }: Props) {
  return (
    <>
      <Head title="Posts" />

      <div className="container mx-auto py-8">
        <h1 className="text-2xl font-bold mb-6">Posts</h1>

        <div className="space-y-4">
          {posts.data.map((post) => (
            <article key={post.id} className="p-4 bg-white rounded-lg shadow">
              <Link href={route('posts.show', post.id)}>
                <h2 className="text-xl font-semibold hover:text-blue-600">
                  {post.title}
                </h2>
              </Link>
              <p className="text-gray-600 mt-2">{post.excerpt}</p>
              <p className="text-sm text-gray-400 mt-2">
                By {post.author.name}
              </p>
            </article>
          ))}
        </div>
      </div>
    </>
  )
}
```

### Form with useForm

```tsx
// resources/js/Pages/Posts/Create.tsx
import { Head, useForm, Link } from '@inertiajs/react'
import { FormEvent } from 'react'

interface Category {
  id: number
  name: string
}

interface Props {
  categories: Category[]
}

export default function Create({ categories }: Props) {
  const { data, setData, post, processing, errors, reset } = useForm({
    title: '',
    body: '',
    category_id: '',
  })

  const handleSubmit = (e: FormEvent) => {
    e.preventDefault()
    post(route('posts.store'), {
      onSuccess: () => reset(),
    })
  }

  return (
    <>
      <Head title="Create Post" />

      <form onSubmit={handleSubmit} className="max-w-2xl mx-auto py-8">
        <div className="mb-4">
          <label htmlFor="title" className="block font-medium mb-1">
            Title
          </label>
          <input
            id="title"
            type="text"
            value={data.title}
            onChange={(e) => setData('title', e.target.value)}
            className="w-full border rounded px-3 py-2"
          />
          {errors.title && (
            <p className="text-red-500 text-sm mt-1">{errors.title}</p>
          )}
        </div>

        <div className="mb-4">
          <label htmlFor="category" className="block font-medium mb-1">
            Category
          </label>
          <select
            id="category"
            value={data.category_id}
            onChange={(e) => setData('category_id', e.target.value)}
            className="w-full border rounded px-3 py-2"
          >
            <option value="">Select a category</option>
            {categories.map((category) => (
              <option key={category.id} value={category.id}>
                {category.name}
              </option>
            ))}
          </select>
          {errors.category_id && (
            <p className="text-red-500 text-sm mt-1">{errors.category_id}</p>
          )}
        </div>

        <div className="mb-4">
          <label htmlFor="body" className="block font-medium mb-1">
            Content
          </label>
          <textarea
            id="body"
            value={data.body}
            onChange={(e) => setData('body', e.target.value)}
            rows={10}
            className="w-full border rounded px-3 py-2"
          />
          {errors.body && (
            <p className="text-red-500 text-sm mt-1">{errors.body}</p>
          )}
        </div>

        <div className="flex gap-4">
          <button
            type="submit"
            disabled={processing}
            className="px-4 py-2 bg-blue-600 text-white rounded disabled:opacity-50"
          >
            {processing ? 'Creating...' : 'Create Post'}
          </button>

          <Link
            href={route('posts.index')}
            className="px-4 py-2 border rounded"
          >
            Cancel
          </Link>
        </div>
      </form>
    </>
  )
}
```

### Persistent Layout

```tsx
// resources/js/Layouts/AppLayout.tsx
import { Link, usePage } from '@inertiajs/react'
import { ReactNode } from 'react'

interface Props {
  children: ReactNode
}

export default function AppLayout({ children }: Props) {
  const { auth } = usePage().props as { auth: { user: { name: string } } }

  return (
    <div className="min-h-screen bg-gray-100">
      <nav className="bg-white shadow">
        <div className="container mx-auto px-4 py-3 flex justify-between">
          <Link href="/" className="font-bold">
            My App
          </Link>
          <span>Welcome, {auth.user.name}</span>
        </div>
      </nav>

      <main className="container mx-auto px-4 py-8">
        {children}
      </main>
    </div>
  )
}

// resources/js/Pages/Dashboard.tsx
import AppLayout from '@/Layouts/AppLayout'

export default function Dashboard() {
  return <h1>Dashboard</h1>
}

// Assign persistent layout
Dashboard.layout = (page: ReactNode) => <AppLayout>{page}</AppLayout>
```

### Laravel Controller

```php
<?php

namespace App\Http\Controllers;

use App\Http\Requests\StorePostRequest;
use App\Models\Post;
use App\Models\Category;
use Illuminate\Http\RedirectResponse;
use Inertia\Inertia;
use Inertia\Response;

class PostController extends Controller
{
    public function index(): Response
    {
        return Inertia::render('Posts/Index', [
            'posts' => Post::with('author:id,name')
                ->latest()
                ->paginate(10),
            'filters' => request()->only('search'),
        ]);
    }

    public function create(): Response
    {
        return Inertia::render('Posts/Create', [
            'categories' => Category::all(['id', 'name']),
        ]);
    }

    public function store(StorePostRequest $request): RedirectResponse
    {
        $post = Post::create([
            ...$request->validated(),
            'user_id' => auth()->id(),
        ]);

        return redirect()
            ->route('posts.show', $post)
            ->with('success', 'Post created successfully.');
    }

    public function show(Post $post): Response
    {
        return Inertia::render('Posts/Show', [
            'post' => $post->load('author', 'category'),
        ]);
    }
}
```

### Shared Data (HandleInertiaRequests)

```php
<?php

namespace App\Http\Middleware;

use Illuminate\Http\Request;
use Inertia\Middleware;

class HandleInertiaRequests extends Middleware
{
    public function share(Request $request): array
    {
        return array_merge(parent::share($request), [
            'auth' => [
                'user' => $request->user() ? [
                    'id' => $request->user()->id,
                    'name' => $request->user()->name,
                    'email' => $request->user()->email,
                ] : null,
            ],
            'flash' => [
                'success' => $request->session()->get('success'),
                'error' => $request->session()->get('error'),
            ],
        ]);
    }
}
```

### Flash Messages Component

```tsx
// resources/js/Components/FlashMessages.tsx
import { usePage } from '@inertiajs/react'
import { useEffect, useState } from 'react'

export default function FlashMessages() {
  const { flash } = usePage().props as {
    flash: { success?: string; error?: string }
  }
  const [visible, setVisible] = useState(false)

  useEffect(() => {
    if (flash.success || flash.error) {
      setVisible(true)
      const timer = setTimeout(() => setVisible(false), 3000)
      return () => clearTimeout(timer)
    }
  }, [flash])

  if (!visible) return null

  return (
    <div className="fixed top-4 right-4 z-50">
      {flash.success && (
        <div className="bg-green-500 text-white px-4 py-2 rounded shadow">
          {flash.success}
        </div>
      )}
      {flash.error && (
        <div className="bg-red-500 text-white px-4 py-2 rounded shadow">
          {flash.error}
        </div>
      )}
    </div>
  )
}
```
