Uses pipeline

[cmizzi]

The main goal here is to use pipeline instead of modifying transformers :

class UserDefinition extends Definition {
    /**
     * getTransformers
     *
     * @return void
     */
    public function getTransformers() {
        return [
            'list' => [
                StudioNet\GraphQL\Pipe\Eloquent\ListPipe::class,
                App\GraphQL\Pipe\User\RolePipe::class
            ],
            // ...
        ];
    }
}

// ...

use Illuminate\Database\Eloquent\Builder;
use Closure;

class RolePipe {
    /**
     * handle
     *
     * @param  Builder $builder
     * @param  Closure $next
     * @param  array $infos
     * @return mixed
     */
    public function handle(Builder $builder, Closure $next, array $infos) {
        // Call $builder method to update SQL query
        //
	// $infos = [
	// 	'root'
	// 	'args'
	// 	'fields'
	// 	'context'
	// 	'info'
	// 	'with'
	// 	'source'
	// 	'rules'
	// 	'filterables'
	// 	'definition'
	// ]

        return $next($builder);

        // All lines here can modify the collection returned by the next method
    }
}

This branch will not remove transformers at all, only the underlying code : it will only calls the pipeline and returns the result. To manage custom transformers, a configuration will be set to manage each new transformer (like #22).

Hi! Are there any updates? When do you think you can make next release?

[cmizzi]

The code seems to work, but I need to make some additional tests to be sure all cases are managed. I need more time :)

Is it possible to use something like AuthMiddleware with this pipeline idea? E.g. I want that some Transformer are only accessible, when user is logged in. Or is there any other option to achieve this?

In graphql-library from rebing there was an option to add middlewares to whole schemas, so it is possible to define an "open" and "protected" schemas.

You cannot use AuthMiddleware directly, but you can create your own and check if the user is logged (with context). But, it could be great to add global middleware per schema :)
