WunderGraph is an API Gateway that turns GraphQL into RPC on the fly, with a focus on its TypeScript Operations. It allows developers to define data sources as dependencies in config and then introspect them into a virtual graph that can be queried using GraphQL. The platform also supports OpenAPI REST & GraphQL APIs, SQL & NOSQL databases, Apollo Federations, and many more. WunderGraph provides a code generation framework that generates fully typesafe hooks for the frontend, making it easier to fetch and display data. It also allows developers to use TypeScript Operations, which can be used to query, mutate, and subscribe to data without using GraphQL. These operations are server-land, meaning they can natively async/await any Promise within them to fetch custom data from any data source. WunderGraph supports authentication with NextAuth.js, allowing developers to gate data fetching across their entire app. The platform also offers a Vercel integration that syncs the WunderGraph application with the Vercel deployment, making it easy to deploy and manage.
