# Grafbase SDK for Gateway Extensions

[![docs.rs](https://img.shields.io/docsrs/grafbase-sdk)](https://docs.rs/grafbase-sdk)

This crate provides building blocks for creating [Grafbase Gateway](https://grafbase.com/docs/reference/gateway/installation) extensions.

There exist three kinds of extensions today:

- [AuthenticationExtension]: Authenticates clients before any GraphQL processing, generating a token with custom data for further extensions.
- [AuthorizationExtension]: Control access to certain fields, objects, interfaces, scalars or enums.
- [ResolverExtension]: Called by the gateway to resolve data, replacing or augmenting a GraphQL subgraph.

Each extension has its dedicated documentation and tutorial you can follow through.
