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.
Hasura works with any GraphQL client. See awesome-graphql for a list of clients. Our frontend tutorial series also have integrations with GraphQL clients for different frameworks.
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 database-based GraphQL schema. Ideal for use-cases like implementing a payment API, or querying data that is not in your database - read more.
Actions are a way to extend Hasura’s schema with custom business logic using custom queries and mutations. Actions can be added to Hasura to handle various use cases such as data validation, data enrichment from external sources and any other complex business logic - 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.
