Question 1

How do I implement pagination with graphql-relay-py?

Accepted Answer

Use connection_definitions to create connection types and connection_from_array in your resolvers to handle cursor-based pagination. The README includes a detailed example from the Star Wars test schema showing how to set this up.

Question 2

graphql-relay-py vs graphene-relay: which is better?

Accepted Answer

Choose graphql-relay-py if you're committed to GraphQL-Core and need a direct, spec-compliant port of Relay JS. Graphene-relay is better suited for Graphene-based projects, offering more integrated features and a higher-level API.

Question 3

Does graphql-relay-py support GraphQL subscriptions?

Accepted Answer

No, the library is focused on Relay compliance for queries and mutations only. Subscriptions are not part of the Relay spec and would need to be implemented separately using GraphQL-Core's capabilities.

Question 4

How to handle authentication in mutations with this library?

Accepted Answer

Authentication logic must be added manually in the mutate_and_get_payload function or through GraphQL middleware, as graphql-relay-py doesn't provide built-in auth helpers, keeping it minimal and focused on Relay patterns.

Question 5

Can I use graphql-relay-py with Django or Flask?

Accepted Answer

Yes, since it's based on GraphQL-Core, you can integrate it with web frameworks like Django or Flask by setting up GraphQL-Core in your views, though additional wiring is needed for full server setup.

Question 6

What's the performance cost of using global IDs?

Accepted Answer

Global IDs add minor overhead for encoding and decoding via to_global_id and from_global_id, but they enable consistent object identification across the schema. Performance impact is generally negligible if implemented efficiently.
