GraphQL @defer and @stream

[luissantos]

Hi everyone,

Thanks for the amazing work you have been doing. Really like the way this server was built and fact that it can be used in so many configurations. There is a bit of a learning curve but its very flexible.

Any plans to support the @defer and @stream directives? How easy would it be to implement these 2 without including it in leto?

I would love to help implement it but I don't know where to start. Any guidance on this would be very much appreciated.

Thanks

Hi sorry for the late response

I would love to help implement it but I don't know where to start. Any guidance on this would be very much appreciated.

I think you could start with the '@skip' and '@include' directives that are already implemented.

The configuration: https://github.com/juancastillo0/leto/blob/8778144bce1ba0dbf65253ee1d78316d2162cbc1/leto_schema/lib/src/directive.dart#L161 and implementation: https://github.com/juancastillo0/leto/blob/8778144bce1ba0dbf65253ee1d78316d2162cbc1/leto_schema/lib/src/utilities/collect_fields.dart#L19

I believe it will require changes to executeRequest in leto (or the functions it calls) and the http response handling in leto_shelf.
