Laravel Follow

User follow unfollow system for Laravel.

💡 The new version has been split into several packages:

• Follow: overtrue/laravel-follow
• Like: overtrue/laravel-like
• Favorite: overtrue/laravel-favorite
• Subscribe: overtrue/laravel-subscribe
• Vote: overtrue/laravel-vote (working in progress)
• Bookmark: overtrue/laravel-bookmark (working in progress)

Installing

$ composer require overtrue/laravel-follow -vvv

Migrations

This step is also optional, if you want to custom the pivot table, you can publish the migration files:

$ php artisan vendor:publish --provider="Overtrue\\LaravelFollow\\FollowServiceProvider" --tag=migrations

Usage

Traits

Overtrue\LaravelFollow\Followable

use Illuminate\Notifications\Notifiable;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Overtrue\LaravelFollow\Followable;

class User extends Authenticatable
{
    <...>
    use Followable;
    <...>
}

API

$user1 = User::find(1);
$user2 = User::find(2);

$user1->follow($user2);
$user1->unfollow($user2);
$user1->toggleFollow($user2);
$user1->acceptFollowRequestFrom($user2);
$user1->rejectFollowRequestFrom($user2);

$user1->isFollowing($user2);
$user2->isFollowdBy($user1);
$user2->hasRequestedToFollow($user1);

$user1->areFollowingEachOther($user2);

Get followings:

$user->followings;

Get followers:

$user->followers;

Follow Requests

If you would like to have some follow requests to need to be accepted by the user being followed, simply override the needsToApproveFollowRequests() method in the model that uses the Followable trait with your custom logic:

public function needsToApproveFollowRequests()
{
    // Your custom logic here
    return (bool) $this->private;
}

Aggregations

// followings count
$user->followings()->count();

// with query where
$user->followings()->where('gender', 'female')->count();

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

List with *_count attribute:

$users = User::withCount(['followings', 'followers'])->get();

foreach($users as $user) {
    // $user->followings_count;
    // $user->followers_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:

$users = User::with('followings')->get();

foreach($users as $user) {
    $user->isFollowing(2);
}

$users = User::with('followers')->get();

foreach($users as $user) {
    $user->isFollowedBy(2);
}

Contributing

You can contribute in one of three ways:

1. File bug reports using the issue tracker.
2. Answer questions or fix bugs on the issue tracker.
3. Contribute new features or update the wiki.

The code contribution process is not very formal. You just need to make sure that you follow the PSR-0, PSR-1, and PSR-2 coding guidelines. Any new code contributions must be accompanied by unit tests where applicable.
