Configuration and Migrations

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

Usage

Traits

Overtrue\LaravelFollow\Traits\Follower

Add the Follower trait to your user model:

use Overtrue\LaravelFollow\Traits\Follower;

class User extends Authenticatable
{
    use Follower;

    <...>
}

Overtrue\LaravelFollow\Traits\Followable

Then add the Followable trait to your followable model, for example App\User:

use Overtrue\LaravelFollow\Traits\Followable;

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

or any other model:

use Overtrue\LaravelFollow\Traits\Followable;

class Channel extends Model
{
    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);
$user2->isFollowedBy($user1);
$user2->hasRequestedToFollow($user1);

Get followings:

$user->followings;
$user->approvedFollowings;
$user->notApprovedFollowings;
foreach($user->followings()->with('followable')->get() as $following)
{
    $following->created_at; // followed at
    
    $following->followable->nickname; // the user attributes
}

Get followers:

$user->followers;
$user->approvedFollowers;
$user->notApprovedFollowers;
foreach($user->followers()->with('followers')->get() as $follower)
{
    $follower->created_at; // followed at
    
    $follower->follower->nickname; // the user attributes
}

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();
$user->approvedFollowings()->count();
$user->notApprovedFollowings()->count();

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

// followers count
$user->followers()->count();
$user->approvedFollowers()->count();
$user->notApprovedFollowers()->count();

List with *_count attribute:

$users = User::withCount(['followings', 'followables'])->get();
// or 
$users = User::withCount(['approvedFollowings', 'approvedFollowers'])->get();

foreach($users as $user) {
    // $user->followings_count;
    // $user->followers_count;
    // or 
    // $user->approved_followings_count;
    // $user->approved_followers_count;
}

Attach user follow status to followable collection

You can use Follower::attachFollowStatus(Collection $followables) to attach the user follow status, it will set has_followed attribute to each model of $followables:

For model

$user1 = User::find(1);

$user->attachFollowStatus($user1);

// result
[
    "id" => 1
    "name" => "user1"
    "private" => false
    "created_at" => "2021-06-07T15:06:47.000000Z"
    "updated_at" => "2021-06-07T15:06:47.000000Z"
    "has_followed" => true  
  ]

For Collection | Paginator | LengthAwarePaginator | array:

$user = auth()->user();

$users = User::oldest('id')->get();

$users = $user->attachFollowStatus($users);

$users = $users->toArray();

// result
[
  [
    "id" => 1
    "name" => "user1"
    "private" => false
    "created_at" => "2021-06-07T15:06:47.000000Z"
    "updated_at" => "2021-06-07T15:06:47.000000Z"
    "has_followed" => true  
  ],
  [
    "id" => 2
    "name" => "user2"
    "private" => false
    "created_at" => "2021-06-07T15:06:47.000000Z"
    "updated_at" => "2021-06-07T15:06:47.000000Z"
    "has_followed" => true
  ],
  [
    "id" => 3
    "name" => "user3"
    "private" => false
    "created_at" => "2021-06-07T15:06:47.000000Z"
    "updated_at" => "2021-06-07T15:06:47.000000Z"
    "has_followed" => false
  ],
  [
    "id" => 4
    "name" => "user4"
    "private" => false
    "created_at" => "2021-06-07T15:06:47.000000Z"
    "updated_at" => "2021-06-07T15:06:47.000000Z"
    "has_followed" => false
  ],
]

For pagination

$users = User::paginate(20);

$user->attachFollowStatus($users);

Order by followers count

You can query users order by followers count with following methods:

  • orderByFollowersCountDesc()
  • orderByFollowersCountAsc()
  • orderByFollowersCount(string $direction = 'desc')

example:

$users = User::orderByFollowersCountDesc()->get();
$mostPopularUser = User::orderByFollowersCountDesc()->first();

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('followables')->get();

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

Events

Event Description
Overtrue\LaravelFollow\Events\Followed Triggered when the relationship is created.
Overtrue\LaravelFollow\Events\Unfollowed Triggered when the relationship is deleted.
