Question 1

graphql-php vs Laravel GraphQL packages like Lighthouse

Accepted Answer

graphql-php is a standalone library offering full spec compliance and flexibility, ideal for any PHP project. Lighthouse is Laravel-specific, providing tighter integration but less control. Choose graphql-php for framework-agnostic or custom setups, and Lighthouse for rapid Laravel development.

Question 2

How to set up authentication in graphql-php

Accepted Answer

Implement authentication by adding custom middleware or resolver logic, such as checking tokens in the context. The library doesn't provide built-in auth, so you'll need to integrate with your existing PHP auth system, like Laravel Passport or Symfony Security.

Question 3

Is graphql-php production ready and scalable

Accepted Answer

Yes, it's used in production by many companies due to its performance optimizations and stability. However, scalability depends on proper schema design, caching strategies, and server infrastructure, not just the library itself.

Question 4

How to handle errors and validation in graphql-php

Accepted Answer

Use the built-in validation for query structure and type errors. For business logic errors, implement custom error handling in resolvers, returning GraphQL-compliant error formats as per the documentation.

Question 5

Can I use graphql-php with Symfony or other PHP frameworks

Accepted Answer

Absolutely, it's framework-agnostic and can be integrated with Symfony, Laravel, or any PHP application. The README provides examples, but you'll need to handle routing and dependency injection manually for each framework.

Question 6

graphql-php subscription setup guide

Accepted Answer

Subscriptions are supported but require additional setup for real-time communication, typically using WebSockets with libraries like Ratchet. Refer to the examples directory in the repository for basic implementations, but expect complexity in production environments.

Question 7

How to cache queries and improve performance in graphql-php

Accepted Answer

Enable built-in query parsing caching via the execution context to reduce overhead. For data caching, implement custom resolvers or middleware, integrating with systems like Redis, as the library focuses on execution rather than data layer optimization.
