The Hasura GraphQL Engine fronts a Postgres database instance and can accept GraphQL requests from your client apps. It can be configured to work with your existing auth system and can handle access control using field-level rules with dynamic variables from your auth system.
You can also merge remote GraphQL schemas and provide a unified GraphQL API.
GraphQL Engine provides easy-to-reason, scalable and performant methods for adding custom business logic to your backend:
Add custom resolvers in a remote schema in addition to Hasura's Postgres-based GraphQL schema. Ideal for use-cases like implementing a payment API, or querying data that is not in your database - read more.
Add asynchronous business logic that is triggered based on database events. Ideal for notifications, data-pipelines from Postgres or asynchronous processing - read more.
Transform data in Postgres or run business logic on it to derive another dataset that can be queried using GraphQL Engine - read more.
