README

yakovenko/laravel-lighthouse-graphql-multi-schema is a Laravel package that provides multi-schema support for Lighthouse GraphQL. It allows you to manage multiple GraphQL schemas within a single Laravel application, streamlining development and extending functionality.

Installation

Requirements

PHP : ^8
Laravel : ^9.0 || ^10.0 || ^11.0
Nuwave Lighthouse : ^6.0

Install the Package

You can install the package using Composer:

composer require yakovenko/laravel-lighthouse-graphql-multi-schema

Publish Configuration

After installing the package, you need to publish the configuration file by running the following command:

php artisan lighthouse-multi-schema:publish-config

This will create a configuration file named lighthouse-multi-schema.php in the config/ directory, where you can set up your GraphQL schemas.

Configuration

In the config/lighthouse-multi-schema.php file, you can define your schemas and their settings. Here’s an example configuration:

return [
    'multi_schemas' => [
        'example' => [
            'route_uri'           => '/example-graphql',
            'route_name'          => 'example-graphql',
            'schema_path'         => base_path("graphql/example.graphql"),
            'schema_cache_path'   => env('LIGHTHOUSE_EXAMPLE_SCHEMA_CACHE_PATH', base_path("bootstrap/cache/example-schema.php")),
            'schema_cache_enable' => env('LIGHTHOUSE_EXAMPLE_CACHE_ENABLE', false),
            'middleware' => [
                // Always set the `Accept: application/json` header.
                Nuwave\Lighthouse\Http\Middleware\AcceptJson::class,

                // Logs in a user if they are authenticated. In contrast to Laravel's 'auth'
                // middleware, this delegates auth and permission checks to the field level.
                Nuwave\Lighthouse\Http\Middleware\AttemptAuthentication::class,

                // Apply your custom middleware here.
                // For example:
                // App\Http\Middleware\ExampleSchemaMiddleware::class,
            ]
        ],
        // Add additional schemas as needed
    ],
];

Middleware Support

You can now add middleware specific to each GraphQL schema. This allows you to apply different middleware configurations based on the schema being used. Simply specify the middleware classes in the middleware array for each schema, and they will be applied to the corresponding routes.

CSRF exceptions

Add your GraphQL routes to the CSRF exceptions.

Open the App/Http/Middleware/VerifyCsrfToken.php file and add your routes to the $except array.

<?php

namespace App\Http\Middleware;

use Illuminate\Foundation\Http\Middleware\VerifyCsrfToken as Middleware;

class VerifyCsrfToken extends Middleware
{
    /**
     * The URIs that should be excluded from CSRF verification.
     *
     * @var array<int, string>
     */
    protected $except = [
        'schema1-graphql',
        'schema2-graphql',
        // Add other routes as needed
    ];
}

Create Directories for Each Schema

Organize your schema files into separate directories for each schema. The structure of these directories and how you split the files is up to you. Here’s an example of one way to organize them:

/graphql
├── schema.graphql
├── schema1.graphql
├── schema2.graphql
└── schema3.graphql

Console Command Example

The lighthouse:clear-cache command is used to manage the cache for your GraphQL schemas. Below are the available usages:

1 - Clear All Schema Caches

To clear the cache for all GraphQL schemas, run the following command:

php artisan lighthouse:clear-cache

This command will delete all cached schema files, ensuring that any changes made to the schemas are reflected the next time they are accessed.

2 - Clear Cache for a Specific Schema

You can also clear the cache for any other schema by replacing {keyYourSchema} with the desired schema name:

php artisan lighthouse:clear-cache {keyYourSchema}

example:

php artisan lighthouse:clear-cache schema1

Replace {keyYourSchema} with the actual name of the schema you want to target. This will specifically remove the cache for that schema only.

Endpoint Schemas

Schema 1: Access the GraphQL schema at: domain.local/schema1-graphql

Schema 2: Access the GraphQL schema at: domain.local/schema2-graphql

Schema 3: Access the GraphQL schema at: domain.local/schema3-graphql

Usage

Once configured, you can use the defined routes for each schema in your application. Each route will utilize its corresponding GraphQL schema. You have a multi-schema setup that allows for an unlimited number of access points, each supporting various mutations and queries tailored to your specific needs. You can define each schema according to your project requirements. This flexibility allows you to create distinct schemas for different parts of your application, ensuring that each area can have customized queries and mutations as needed.
