GraphQL Yoga is a performant, production‑ready GraphQL server that streamlines setup with sensible defaults, built‑in support for subscriptions, file uploads, and GraphiQL, and runs everywhere via the WHATWG Fetch API. It’s aimed at developers who need a feature‑rich, extensible GraphQL backend that works seamlessly across Node, serverless platforms, and edge runtimes while remaining easy to integrate with any GraphQL ecosystem.
