PHPStan extension for PHP GraphQL Server

This is super-convenient companion if you use vojtech-dobes/php-graphql-server and PHPStan. With this extension, PHPStan will be able to point out:

• mismatch between GraphQL Schema & what your resolvers actually return
• mismatch between GraphQL Schema & what your resolvers actually accept as arguments
• mismatch between declared parent value type and what resolver will actually receive
• supports utility resolvers like PropertyFieldResolver etc.

Installation

To install the latest version, run the following command:

composer require vojtech-dobes/phpstan-php-graphql-server

Then you can register in your phpstan.neon:

includes:
  - vendor/vojtech-dobes/phpstan-php-graphql-server/extension.neon

graphql:
  generatedDir: "<path to temp directory>"
  schemas:
    - "<path to your Schema file>"

Next you have to tell the extension about your resolvers. If you're using framework integration, use corresponding package:

• Integration: vojtech-dobes/php-graphql-server-nette-integration (for Nette Framework)
  Package: vojtech-dobes/phpstan-php-graphql-server-nette-integration

In case of custom setup, please implement Vojtechdobes\PHPStan\GraphQL\Adapter interface and register like this in phpstan.neon:

services:
  - class: MyCustomAdapter
