Hasura GraphQL 101 (Instant GraphQL Postgres API Server with No Code)

Hasura provides a convenient way to setting up a GraphQL server on top of a PostgreSQL database, without writing any logic to achieve that. It provides a compiler that reads your PostgreSQL database tables and other metadata and generates GraphQL queries, mutations and subscription operations that are exposed over a GraphQL endpoint. Hasura also provides a dashboard for managing our PostgreSQL database with other features like triggering events and enabling authentication over your data.
