README

A powerful and elegant GraphQL query builder for PHP, designed specifically for Laravel applications. Build GraphQL queries and mutations with a fluent, type-safe interface.

Features

• Fluent API: Build GraphQL queries using an intuitive, chainable interface
• Type Safety: Full PHP 8+ type hints for better IDE support and fewer runtime errors
• Laravel Integration: Built with Laravel conventions and auto-discovery
• Variable Support: Automatic variable handling with type safety
• Fragment Support: Create reusable query fragments
• Inline Fragments: Type-based conditional field selection

Requirements

• PHP 8.3 or higher
• Laravel 11.0 or higher

Installation

You can install the package via composer:

composer require secundo/laravel-graphql-query-builder

The service provider will be automatically registered using Laravel's package discovery.

Quick Start

Basic Query

use Secundo\GraphQL\Builder;

$builder = new Builder();

$query = $builder->query()
    ->field('products', [], ['id', 'title', 'handle'])
    ->toGraphQL();

// Output:
// query {
//   products {
//     id
//     title
//     handle
//   }
// }

Query with Arguments

$query = $builder->query()
    ->field('product', ['id' => 'gid://shopify/Product/123'], ['id', 'title', 'handle'])
    ->toGraphQL();

// Output:
// query {
//   product(id: "gid://shopify/Product/123") {
//     id
//     title
//     handle
//   }
// }

Nested Fields

$query = $builder->query()
    ->field('products', ['first' => 10], function ($field) {
        $field->field('edges', [], function ($field) {
            $field->field('node', [], ['id', 'title']);
            $field->field('cursor');
        });
        $field->field('pageInfo', [], ['hasNextPage', 'endCursor']);
    })
    ->toGraphQL();

Using Variables

$query = $builder->query('GetProduct')
    ->variable('id', 'ID!', 'gid://shopify/Product/123')
    ->field('product', ['id' => '$id'], ['id', 'title', 'description'])
    ->toGraphQL();

// Get variable values for the request
$variables = $builder->getVariableValues();

// Output:
// query GetProduct($id: ID!) {
//   product(id: $id) {
//     id
//     title
//     description
//   }
// }
// Variables: {"id": "gid://shopify/Product/123"}

Mutations

$mutation = $builder->mutation('UpdateProduct')
    ->variable('id', 'ID!')
    ->variable('input', 'ProductInput!')
    ->field('productUpdate', ['id' => '$id', 'product' => '$input'], function ($field) {
        $field->field('product', [], ['id', 'title']);
        $field->field('userErrors', [], ['field', 'message']);
    })
    ->toGraphQL();

Fragments

$query = $builder->query()
    ->fragment('ProductFields', 'Product', ['id', 'title', 'handle', 'createdAt'])
    ->field('products', [], function ($field) {
        $field->field('edges', [], function ($field) {
            $field->field('node', [], ['...ProductFields']);
        });
    })
    ->toGraphQL();

Inline Fragments

$query = $builder->query()
    ->field('node', ['id' => '$id'], function ($field) {
        $field->field('id');
        $field->inlineFragment('Product', function ($fragment) {
            $fragment->field('title');
            $fragment->field('handle');
        });
        $field->inlineFragment('Collection', function ($fragment) {
            $fragment->field('title');
            $fragment->field('description');
        });
    })
    ->toGraphQL();

// Output:
// query {
//   node(id: $id) {
//     id
//     ... on Product {
//       title
//       handle
//     }
//     ... on Collection {
//       title
//       description
//     }
//   }
// }

Advanced Usage

Multiple Variables with Default Values

$query = $builder->query('SearchProducts')
    ->variables([
        'first' => ['type' => 'Int', 'value' => 10],
        'query' => ['type' => 'String', 'value' => 'title:shirt'],
        'sortKey' => ['type' => 'ProductSortKeys', 'value' => 'CREATED_AT']
    ])
    ->field('products', [
        'first' => '$first',
        'query' => '$query',
        'sortKey' => '$sortKey'
    ], ['id', 'title']);

Field Aliases

use Secundo\GraphQL\Types\Field;

$field = new Field('product');
$field->alias('myProduct')
    ->arguments(['id' => 'gid://shopify/Product/123'])
    ->fields(['id', 'title']);

Directives

$field = new Field('expensiveField');
$field->directive('include', ['if' => '$includeExpensive'])
    ->fields(['data']);

$field = new Field('debugInfo');
$field->directive('skip', ['if' => '$production'])
    ->fields(['logs']);

Laravel Integration

Using the Facade

use Secundo\GraphQL\Facades\GraphQL;

$query = GraphQL::query()
    ->field('shop', [], ['name', 'email'])
    ->toGraphQL();

Dependency Injection

use Secundo\GraphQL\GraphQL;

class ProductController extends Controller
{
    public function __construct(
        private GraphQL $graphql
    ) {}

    public function index()
    {
        $query = $this->graphql->query()
            ->field('products', ['first' => 10], ['id', 'title'])
            ->toGraphQL();
            
        // Execute query...
    }
}
