optigov/eloquent-graphql

This package provides automatic creation of GraphQL types and fields from Eloquent models.

v2.4.8 2024-04-16 12:01 UTC

README

This package automatically creates GraphQL types and fields with their resolvers for the webonyx/graphql-php library from Eloquent models. The package utilizes the PHP DocBlock annotations to determine the GraphQL types and fields. It supports pagination, filtering and ordering on properties returning multiple models using a query builder for optimal performance.

Installation

composer require optigov/eloquent-graphql

Usage

Annotate your Models

In order to make fields available in GraphQL, annotate your Models with the @property annotation.

/**
 * @property int $id
 * @property string $name
 * @property Author $author
 * @property-read $created_at
 * @property-read $updated_at
 */ 
class Book {
    // ...
}
/**
 * @property int $id
 * @property string $first_name
 * @property string $last_name
 * @property Books[] $books
 * @property-read $created_at
 * @property-read $updated_at
 */ 
class Author {
    // ...
}

Build your Schema

Build your Schema using the EloquentGraphQLService class.

use App\Models\Book;
use App\Models\Author;
use GraphQL\Type\Schema;
use EloquentGraphQL\Services\EloquentGraphQLService;

$graphQLService = new EloquentGraphQLService();

$schema = new Schema([
    'query' => $graphQLService->query()
        ->view(Book::class)
        ->view(Author::class)
        ->all(Book::class)
        ->all(Author::class)
        ->build(),
    'mutation' => $graphQLService->mutation()
        ->create(Book::class)
        ->create(Author::class)
        ->update(Book::class)
        ->update(Author::class)
        ->delete(Book::class)
        ->delete(Author::class)
        ->build(),
]);

Go Further

Pagination

Use the @paginate annotation to paginate properties returning multiple models using a query builder - for example has many relations.

/**
 * ...
 * @property Books[] $books @paginate
 * ...
 */
class Author {
    // ...
}

Filtering and Ordering

Use the @filterable and @orderable annotations to enable filtering and ordering on properties returning multiple models using a query builder - for example has many relations.

/**
 * ...
 * @property Books[] $books @paginate @filterable @orderable
 * ...
 */
class Author {
    // ...
}

Custom Fields

You can add custom fields to your GraphQL types using the field() method.

$schema = new Schema([
    'query' => $graphQLService->query()
        ->view(Book::class)
        ->field('customField', [
            'type' => Type::string(),
            'resolve' => function ($root, $args) {
                return 'Hello World!';
            }
        ])
        ->build(),
]);
