The Pipeline pattern is a design pattern used to process data in a series of sequential stages or steps.

• it passes data from one class to another
• example: middleware in Laravel

Laravel example

use Closure;
use App\Models\User;
use Illuminate\Support\Facades\Pipeline;

$user = Pipeline::send($user)
    ->through([
        function (User $user, Closure $next) {
            // ...

            return $next($user);
        },
        function (User $user, Closure $next) {
            // ...

            return $next($user);
        },
    ])
    ->then(fn (User $user) => $user);
