GraphQL CRUD can be applied out of the box using https://graphback.dev
Graphback provides the ability to generate a schema that will be fully compatible with GraphQL CRUD and also connect it directly to Postgres, MongoDB and other datasources without writing any code.
Offix provides a reference implementation for delta sync queries and implements GraphQL CRUD on the client side.
Libraries that partialy implement GraphQL CRUD
This specification was built based on numerous community implementations:
- AWS AppSync
- GraphQL CLI
Relation to Relay
Relay (https://relay.dev/) provides similar capabilites to GraphQL CRUD. However, GraphQL CRUD takes a more lenient and less verbose approach to building GraphQL queries. Both standard are incompatibile with each other.
