EdgeDB supports GraphQL queries natively out of the box. Not everything that can be expressed in EdgeQL can easily be queried using GraphQL, but generally setting up aliases for complex expressions makes it possible to then use use GraphQL to query them.
EdgeDB exposes the Types and Expression Aliases for GraphQL
            querying. Types and expression aliases from the default module are
            exposed using their short names, whereas items from another module use
            the module name as a prefix.
In order to set up GraphQL access to the database add the following to the schema:
using extension graphql;Then create a new migration and apply it using edgedb create-migration and edgedb migrate, respectively.
http://127.0.0.1:<instance-port>/db/<database-name>/graphql will
            expose GraphQL API. Check the credentials file for your instance at
            $HOME/.edgedb/credentials to find out which port the instance is
            using.
http://127.0.0.1:<instance-port>/db/<database-name>/graphql/explore
            will bring up a GraphiQL interface to EdgeDB. This interface can be
            used to try out queries and explore the GraphQL capabilities.
