+# rdey-graphql-federation-bundle
+
+A tiny, simplistic and fragile bundle to integrate overblog/graphql-bundle 
+(specifically 0.13 and 0.14) and skillshare/apollo-federation-php (1.6).
+
+This bundle shouldn't have to exist, as this should more properly belong 
+in overblog/graphql-bundle, but here we are.
+
+## Usage
+
+You need to manually define your federated types as Symfony services. 
+These services need to be tagged with `overblog_graphql.type`. Our
+suggestion is this:
+
+```yaml
+    App\GraphQL\Type\:
+        resource: '../src/GraphQL/Type'
+        tags:
+            - { name: 'overblog_graphql.type' }
+```
+
+Your type class can look a little something like this (see the docs for
+skillshare/apollo-federation-php for more info):
+
+```php
+<?php
+
+declare(strict_types=1);
+
+namespace App\GraphQL\Type;
+
+use Apollo\Federation\Types\EntityObjectType;
+use Overblog\GraphQLBundle\Definition\Resolver\AliasedInterface;
+use GraphQL\Type\Definition\Type;
+
+class TestEntity extends EntityObjectType implements AliasedInterface
+{
+    public function __construct()
+    {
+        parent::__construct([
+            'name' => 'TestEntity',
+            'keyFields' => ['id', 'email'],
+            'fields' => [
+                'id' => [
+                    'type' => Type::int(),
+                ],
+                'email' => [
+                    'type' => Type::string(),
+                ],
+                'foobar' => [
+                    'type' => Type::string(),
+                ]
+            ]
+        ]);
+    }
+
+    public static function getAliases(): array
+    {
+        return ['TestEntity'];
+    }
+}
+```
+
+You can also dump a schema with the correct Federation directives using `bin/console redeye:graphql:dump-federated`.
