-
CORS default Configuration (#40)
The Router will allow only the https://studio.apollographql.com origin by default, instead of any origin. This behavior can still be tweaked in the YAML configuration
-
Skip and Include directives in post processing (PR #626)
The Router now understands the @skip and @include directives in queries, to add or remove fields depending on variables. It works in post processing, by filtering fields after aggregating the subgraph responses.
-
Add an option to deactivate introspection (PR #749)
While schema introspection is useful in development, we might not want to expose the entire schema in production, so the router can be configured to forbid introspection queries as follows:
server:
introspection: false-
Remove
hasNextfrom our response objects (PR #733)hasNextis a field in the response that may be used in future to support features such as defer and stream. However, we are some way off supporting this and including it now may break clients. It has been removed. -
Extend Apollo uplink configurability (PR #741) Uplink url and poll interval can now be configured via command line arg and env variable:
--apollo-schema-config-delivery-endpoint <apollo-schema-config-delivery-endpoint> The endpoint polled to fetch the latest supergraph schema [env: APOLLO_SCHEMA_CONFIG_DELIVERY_ENDPOINT=] --apollo-schema-poll-interval <apollo-schema-poll-interval> The time between polls to Apollo uplink. Minimum 10s [env: APOLLO_SCHEMA_POLL_INTERVAL=] [default: 10s]
In addition, other existing uplink env variables are now also configurable via arg.
-
Make deduplication and caching more robust against cancellation PR #752
Cancelling a request could put the router in an unresponsive state where the deduplication layer or cache would make subgraph requests hang.
