Question 1

How do I rename a scalar in graphql-java-datetime?

Accepted Answer

You can rename scalars by adding properties in application.yaml, such as setting 'graphql.datetime.scalars.date.scalar-name' to your preferred name. This is documented in the README under the configuration section for each scalar type.

Question 2

Does graphql-java-datetime work with Java 8's time API?

Accepted Answer

Yes, it fully supports Java 8 time API classes like LocalDate, LocalDateTime, and Duration. The library is designed to integrate seamlessly with modern Java date/time handling, as shown in the serialization tables.

Question 3

GraphQL Java DateTime vs graphql-java-scalars for date/time handling?

Accepted Answer

graphql-java-datetime is specialized for RFC 3339 compliant date/time scalars with framework starters, while graphql-java-scalars offers a broader set of scalar types but less focus on date/time standards. Choose based on your need for standardization and ease of integration with specific frameworks.

Question 4

How to enable automatic time zone conversion in graphql-java-datetime?

Accepted Answer

Enable it by setting 'graphql.datetime.scalars.zone-conversion-enabled: true' in your application.yaml. This automatically converts LocalDateTime between UTC and the default time zone, as explained in the README configuration options.

Question 5

What formats does graphql-java-datetime support for Duration?

Accepted Answer

It supports ISO 8601 duration formats like PT1H30M or P1DT3H30M, as shown in the serialization table. These are standard representations for time intervals in GraphQL queries and responses.

Question 6

Is graphql-java-datetime compatible with GraphQL subscriptions?

Accepted Answer

Yes, since it's a scalar library for graphql-java, it should work with subscriptions as long as the underlying framework supports them. However, compatibility may vary based on the starter used, so check the specific framework documentation.
