README

This package provides highly powerful @searchBy, @sortBy, @stream directives for lighthouse-php. The @searchBy directive provides basic conditions like =, >, <, etc, relations, not (<condition>), enums, and custom operators support. All are strictly typed so you no need to use Mixed type anymore. The @sortBy is not only about standard sorting by columns but also allows use relations. 😎

Requirements

Installation

composer require lastdragon-ru/lara-asp-graphql

Configuration

Config can be used, for example, to customize supported operators for each type. Before this, you need to publish it via the following command, and then you can edit config/lara-asp-graphql.php.

php artisan vendor:publish --provider=LastDragon_ru\\LaraASP\\GraphQL\\PackageProvider --tag=config

Directives

@searchBy

Probably the most powerful directive to provide search (where conditions) for your GraphQL queries.

Read more.

@sortBy

Probably the most powerful directive to provide sort (order by conditions) for your GraphQL queries.

Read more.

@stream 🧪

Unlike the @paginate (and similar) directive, the @stream provides a uniform way to perform Offset/Limit and Cursor pagination of Eloquent/Query/Scout builders. Filtering and sorting enabled by default via @searchBy and @sortBy directives.

Read more.

@type

Converts scalar into GraphQL Type. Similar to Lighthouse's @scalar directive, but uses Laravel Container to resolve instance and also supports PHP enums.

Read more.

Scalars

Important

You should register the Scalar before use, it can be done via AstManipulator (useful while AST manipulation), TypeRegistry, or as a custom scalar inside the Schema:

scalar JsonString
@type(
    class: "LastDragon_ru\\LaraASP\\GraphQL\\Scalars\\JsonStringType"
)

JsonString

Represents JSON string.

Read more.

Scout

Scout is also supported 🤩. You just need to add @search directive to an argument. Please note that available operators depend on Scout itself.

Please note that if the @search directive added, the generated query will expect the Scout builder only. So recommended using non-nullable String! type to avoid using the Eloquent builder (it will happen if the search argument missed or null; see also lighthouse#2465.

Input type auto-generation

The type used with the Builder directives like @searchBy/@sortBy may be Explicit (when you specify the input name field(where: InputTypeName @searchBy): [Object!]!) or Implicit (when the _ used, field(where: _ @searchBy): [Object!]!). They are processing a bit differently.

For Explicit type, all fields except unions and marked as ignored (if supported by the directive) will be included.

For Implicit type, the following rules are applied (in this order; concrete directive may have differences, please check its docs):

• Union? - exclude
• Has Operator of the concrete directive? - include
• Has Nuwave\Lighthouse\Support\Contracts\FieldResolver?
  • Yes
    • Is Nuwave\Lighthouse\Schema\Directives\RelationDirective? - Include if is the Object or list of Object
    • Is Nuwave\Lighthouse\Schema\Directives\RenameDirective? - Include if allowed, is scalar/enum (not Object), and no arguments
    • Otherwise - exclude
  • No
    • Is Object or has arguments - exclude
    • Otherwise - include
• Ignored (if supported)? - exclude

When converting the field, some of the original directives will be copied into the newly generated field. For the Explicit type, all directives except operators of other directives will be copied. For Implicit type, you can use Config::$allowedDirectives setting to control. Be aware of directive locations - the package doesn't perform any checks to ensure that the copied directive allowed on INPUT_FIELD_DEFINITION, it just copies it as is.

Builder field/column name

By default @searchBy/@sortBy will convert nested/related fields into dot string: eg {user: {name: asc}} will be converted into user.name. You can redefine this behavior by BuilderFieldResolver:

// AppProvider

$this->app->bind(
    LastDragon_ru\LaraASP\GraphQL\Builder\Contracts\BuilderFieldResolver::class,
    MyBuilderFieldResolver::class,
);

Builder type detection

Directives like @searchBy/@sortBy have a unique set of operators and other features for each type of Builder (Eloquent/Scout/etc). Detection of the current Builder works fine for standard Lighthouse directives like @all, @paginated, @search, etc and relies on proper type hints of Relations/Queries/Resolvers. You may get BuilderUnknown error if the type hint is missed or the union type is used.

<?php declare(strict_types = 1);

namespace App\Models;

use Illuminate\Database\Eloquent\Relations\BelongsTo;

class Comment extends Model {
    protected $table = 'comments';

    /**
     * Will NOT work
     */
    public function user() {
        return $this->belongsTo(User::class);
    }

    /**
     * Must be
     */
    public function user(): BelongsTo {
        return $this->belongsTo(User::class);
    }
}

If you implement custom directives which internally enhance the Builder (like standard directives do), you may get BuilderUnknown error because the proper/expected builder type was not detected. In this case, your directive should implement BuilderInfoProvider interface and to specify the builder type explicitly.

<?php declare(strict_types = 1);

namespace App\GraphQL\Directives;

use Illuminate\Database\Eloquent\Builder;
use LastDragon_ru\LaraASP\GraphQL\Builder\BuilderInfo;
use LastDragon_ru\LaraASP\GraphQL\Builder\Contracts\BuilderInfoProvider;
use LastDragon_ru\LaraASP\GraphQL\Builder\Contracts\TypeSource;
use Nuwave\Lighthouse\Support\Contracts\Directive;
use Override;

class CustomDirective implements Directive, BuilderInfoProvider {
    #[Override]
    public static function definition(): string {
        return 'directive @custom';
    }

    #[Override]
    public function getBuilderInfo(TypeSource $source): ?BuilderInfo {
        return BuilderInfo::create(Builder::class);
    }

    public function __invoke(): mixed {
        return null;
    }
}

Printer

The package provides bindings for Printer so you can simply use:

<?php declare(strict_types = 1);

use LastDragon_ru\GraphQL\Printer\Contracts\DirectiveFilter;
use LastDragon_ru\GraphQL\Printer\Contracts\Printer;
use LastDragon_ru\GraphQL\Printer\Settings\DefaultSettings;
use LastDragon_ru\LaraASP\Dev\App\Example;
use Nuwave\Lighthouse\Schema\SchemaBuilder;

$schema   = app()->make(SchemaBuilder::class)->schema();
$printer  = app()->make(Printer::class);
$settings = new DefaultSettings();

$printer->setSettings(
    $settings->setDirectiveDefinitionFilter(
        new class() implements DirectiveFilter {
            #[Override]
            public function isAllowedDirective(string $directive, bool $isStandard): bool {
                return !in_array($directive, ['eq', 'all', 'find'], true);
            }
        },
    ),
);

Example::raw($printer->print($schema), 'graphql');
