📖 Usage

Reactions

1. Add trait to your model:

use TrueFans\LaravelReactable\Traits\HasReactions;

class Post extends Model
{
    use HasReactions;
}

2. Eager load in controller (prevents N+1 queries):

public function index()
{
    $posts = Post::with(['user', 'reactions'])
        ->latest()
        ->paginate(10);

    return view('posts.index', compact('posts'));
}

3. Display in Blade:

<livewire:tflr_reactions :model="$post" :key="'post-reactions-'.$post->id" />

Comments

1. Add trait to your model:

use TrueFans\LaravelReactable\Traits\HasComments;

class Post extends Model
{
    use HasComments;
}

2. Eager load comment counts (prevents N+1 queries):

public function index()
{
    $posts = Post::with(['user', 'reactions'])
        ->withCount('comments')  // Important for performance!
        ->latest()
        ->paginate(10);

    return view('posts.index', compact('posts'));
}

3. Display in Blade:

<livewire:tflr_comments :model="$post" :key="'post-comments-'.$post->id" />

Configuration

Customize reactions and enable/disable features in config/reactable.php:

return [
    'reaction_types' => [
        'like' => ['icon' => '👍', 'label' => 'Like', 'color' => 'blue'],
        'love' => ['icon' => '❤️', 'label' => 'Love', 'color' => 'red'],
        // Add your own custom reactions!
    ],
    
    'comments' => [
        'enable_reactions' => true, // Allow reactions on comments
    ],
];

🎯 Advanced Usage

Trait Methods

The HasReactions trait provides these methods:

// Add/remove reactions
$post->react('like', $user);  // User defaults to auth()->user()
$post->unreact($user);

// Check reactions
$post->hasReactedBy($user);  // Returns bool
$post->getReactionBy($user);  // Returns 'like', 'love', etc. or null

// Get counts
$post->getReactionsSummary();  // Returns ['like' => 5, 'love' => 3, ...]
$post->getTotalReactionsCount();  // Returns int
$post->getReactionsCountByType('like');  // Returns int

The HasComments trait provides these methods:

// Add/remove comments
$post->addComment('Great post!', $user);
$post->removeComment($commentId, $user);

// Check comments
$post->hasCommentedBy($user);  // Returns bool
$post->comments()->count();  // Get total comments

Custom Reaction Permissions

Override the canReact method in your model to control who can react:

class Post extends Model
{
    use HasReactions;
    
    public function canReact(string $type): bool
    {
        // Prevent users from reacting to their own posts
        if (auth()->id() === $this->user_id) {
            return false;
        }
        
        return true;
    }
}

🎯 Advanced Usage

IMPORTANT: Always eager load relationships when displaying multiple models with Reactions or Comments components.

For Reactions Component

// ✅ CORRECT - Eager load reactions
$posts = Post::with(['user', 'reactions'])
    ->latest()
    ->paginate(10);

// ❌ WRONG - Will cause N+1 queries
$posts = Post::with('user')
    ->latest()
    ->paginate(10);

For Comments Component

// ✅ CORRECT - Eager load comment counts
$posts = Post::with(['user', 'reactions'])
    ->withCount('comments')  // Adds comments_count attribute
    ->latest()
    ->paginate(10);

Complete Example Controller

use App\Models\Post;
use Illuminate\View\View;

class PostController extends Controller
{
    public function index(): View
    {
        $posts = Post::with(['user', 'reactions'])
            ->withCount('comments')
            ->latest()
            ->paginate(10);

        return view('posts.index', compact('posts'));
    }

    public function show(Post $post): View
    {
        $post->load('user');
        $post->loadCount('comments');

        return view('posts.show', compact('post'));
    }
}

Database Queries

Get posts with specific reactions:

// Get posts with specific reaction
$lovedPosts = Post::whereHas('reactions', function($query) {
    $query->where('type', 'love');
})->get();

// Count reactions for a post
$reactionCount = $post->reactions()->count();

// Get all users who reacted to a post
$users = $post->reactions()->with('user')->get()->pluck('user');

🧪 Testing

Create test data with the included seeder:

use TrueFans\LaravelReactable\Models\Reaction;

// Create reactions programmatically
public function run(): void
    {

        $reactionTypes = ['like', 'love', 'laugh', 'wow', 'sad', 'angry'];

        Post::factory()
            ->count(10)
            ->has(
                Reaction::factory()
                    ->count(100)
                    ->state(fn() => [
                        'user_id'        => User::factory(),
                        'type'           => fake()->randomElement($reactionTypes),
                        'reactable_type' => Post::factory(),
                    ])
            )
            ->create();

    }
