The Hasura Metadata SDK is a collection of type definitions for Hasura metadata in various programming languages. It aims to enhance user experience by providing a platform for building complex tooling and programmatic workflows around interacting with metadata, as well as offering enhanced integration for maintaining flow-state while working in editor environments on Hasura projects. The SDK includes pre-generated SDKs for TypeScript, Python 3.7 Dataclasses + MyPy, Golang, and Haskell. Users can also generate definitions in other languages if their preferred language is not readily available.
