👍 User-like features for Laravel Application.

Installing

composer require overtrue/laravel-like -vvv

Configuration and Migrations

php artisan vendor:publish --provider="Overtrue\LaravelLike\LikeServiceProvider"

Usage

Traits

Overtrue\LaravelLike\Traits\Liker

use Illuminate\Notifications\Notifiable;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Overtrue\LaravelLike\Traits\Liker;

class User extends Authenticatable
{
    use Liker;

    <...>
}

Overtrue\LaravelLike\Traits\Likeable

use Illuminate\Database\Eloquent\Model;
use Overtrue\LaravelLike\Traits\Likeable;

class Post extends Model
{
    use Likeable;

    <...>
}

API

$user = User::find(1);
$post = Post::find(2);

$user->like($post);
$user->unlike($post);
$user->toggleLike($post);

$user->hasLiked($post);
$post->isLikedBy($user);

Get user likes with pagination:

$likes = $user->likes()->with('likeable')->paginate(20);

foreach ($likes as $like) {
    $like->likeable; // App\Post instance
}

Get object likers:

foreach($post->likers as $user) {
    // echo $user->name;
}

with pagination:

$likers = $post->likers()->paginate(20);

foreach($likers as $user) {
    // echo $user->name;
}

Aggregations

// all
$user->likes()->count();

// short way
$user->totalLikes;

// with type
$user->likes()->withType(Post::class)->count();

// likers count
$post->likers()->count();

// short way
$post->totalLikers

List with *_count attribute:

// likes_count
$users = User::withCount('likes')->get();

foreach($users as $user) {
    // $user->likes_count;
}

// likers_count
$posts = User::withCount('likers')->get();

foreach($posts as $post) {
    // $post->likes_count;
}

N+1 issue

To avoid the N+1 issue, you can use eager loading to reduce this operation to just 2 queries. When querying, you may specify which relationships should be eager loaded using the with method:

// Liker
$users = App\User::with('likes')->get();

foreach($users as $user) {
    $user->hasLiked($post);
}

// Likeable
$posts = App\Post::with('likes')->get();
// or
$posts = App\Post::with('likers')->get();

foreach($posts as $post) {
    $post->isLikedBy($user);
}

Of course we have a better solution, which can be found in the following section：

Attach user like status to likeable collection

You can use Liker::attachLikeStatus($likeables) to attach the user like status, it will attach has_liked attribute to each model of $likeables:

For model

$post = Post::find(1);

$post = $user->attachLikeStatus($post);

// result
[
    "id" => 1
    "title" => "Add socialite login support."
    "created_at" => "2021-05-20T03:26:16.000000Z"
    "updated_at" => "2021-05-20T03:26:16.000000Z"
    "has_liked" => true
 ],

For Collection | Paginator | LengthAwarePaginator | array:

$posts = Post::oldest('id')->get();

$posts = $user->attachLikeStatus($posts);

$posts = $posts->toArray();

// result
[
  [
    "id" => 1
    "title" => "Post title1"
    "created_at" => "2021-05-20T03:26:16.000000Z"
    "updated_at" => "2021-05-20T03:26:16.000000Z"
    "has_liked" => true
  ],
  [
    "id" => 2
    "title" => "Post title2"
    "created_at" => "2021-05-20T03:26:16.000000Z"
    "updated_at" => "2021-05-20T03:26:16.000000Z"
    "has_liked" => fasle
  ],
  [
    "id" => 3
    "title" => "Post title3"
    "created_at" => "2021-05-20T03:26:16.000000Z"
    "updated_at" => "2021-05-20T03:26:16.000000Z"
    "has_liked" => true
  ],
]

For pagination

$posts = Post::paginate(20);

$user->attachLikeStatus($posts);
