README

此 Laravel 提供者提供了使用 GraphQL 的集成，通过 Railt GraphQL。

要求

• php: ^8.1
• laravel: ^9.0|^10.0
• railt/railt: ^2.0

安装

库作为 composer 仓库可用，可以在项目的根目录中使用以下命令安装。

$ composer require railt/laravel-provider

然后，将提供者添加到 config/app.php 文件中的 providers 列表

    'providers' => [
        // ...
        /*
         * Package Service Providers...
         */
         Railt\LaravelProvider\RailtServiceProvider::class,
         
         /*
          * Application Service Providers...
          */
         // ...
    ],

要发布资产（配置文件、示例文件等），请使用以下命令

$ php artisan vendor:publish --tag=railt

配置

所有应用程序配置都位于 config/railt.php 文件中。

主应用程序的默认路由

• /graphql - 用于 GraphQL 请求。
• /graphiql - 用于 GraphQL 演示场（GraphQL Web IDE）。

所有配置选项

以下是一个包含所有可能选项的提供者配置示例。
