Question 1

How does GraphQL Yoga compare to Apollo Server?

Accepted Answer

GraphQL Yoga is better for quick setup and modern standards like Fetch API, offering a lighter weight and more configurable approach. Apollo Server has a larger ecosystem and more pre-built integrations, but Yoga excels in simplicity and performance optimizations.

Question 2

How to implement file uploads with GraphQL Yoga?

Accepted Answer

GraphQL Yoga natively supports file uploads via the GraphQL multipart specification. You can handle multipart requests directly without additional middleware—just define your mutation types and use the built-in handling for seamless upload functionality.

Question 3

Is GraphQL Yoga good for serverless deployments?

Accepted Answer

Yes, thanks to its Fetch API compatibility, GraphQL Yoga runs well in serverless environments like Vercel or AWS Lambda. It's designed to be lightweight and stateless, making it ideal for cloud platforms with minimal configuration overhead.

Question 4

Can I use GraphQL Yoga with Express.js?

Accepted Answer

While GraphQL Yoga is built on modern standards and can integrate with Express.js via adapters, it's optimized for standalone use or with Fetch-compatible servers. For Express-specific features, you might need additional setup compared to native Express GraphQL solutions.

Question 5

What are the subscription options in GraphQL Yoga?

Accepted Answer

GraphQL Yoga supports subscriptions over both WebSockets and Server-Sent Events (SSE), giving flexibility for real-time updates. It includes built-in handling for connection management, making it easy to implement without external libraries.

Question 6

How to add custom middleware or plugins in GraphQL Yoga?

Accepted Answer

Use the plugin system to extend functionality—create or import plugins to add logging, authentication, or other features. The modular architecture allows hooks into various lifecycle events, but it requires familiarity with the plugin API for advanced use.
