Request: a reactive GraphQL Spring Boot starter

[breun]

Currently graphql-spring-boot-starter makes it easy to setup a GraphQL server, but this starter uses graphql-java-servlet which depends on the Servlet API, which uses blocking I/O, and therefore cannot run on a non-blocking reactive runtime like the Netty-based Spring WebFlux.

For high concurrency use cases it would be great to be able to get away from the blocking one-thread-per-request model and be able to use reactive programming (or for instance Kotlin coroutines, which will be supported out of the box in Spring Boot 2.2) to implement a GraphQL server.

I see https://github.com/graphql-java/graphql-java-spring does offer a WebFlux option, I might have to look into that, but that doesn't seem to involve graphql-java-tools.

Correct. First step for this project is refactoring the servlet lib to allow re-use of certain components, and then will look at supporting WebFlux. Groeten, Michiel

any info on that?

Started to split up graphql-java-servlet to remove the servlet dependency: graphql-java-kickstart/graphql-java-servlet#217

Extracted a separate graphql-java-tools starter that could be used with the webflux starter provided by graphql-java team: #301

Started a sample using webflux with the graphql-java-kickstart libs: https://github.com/graphql-java-kickstart/samples/tree/master/spring-boot-webflux. This will be moved into a separate starter at some point. No support for batch requests or subscriptions yet.

Any contributions are appreciated.

Created a starter for webflux including support for subscriptions (based on websockets). Batched queries not yet supported though.

It's not yet released, but you can see how it's used in the sample: https://github.com/graphql-java-kickstart/samples/tree/master/spring-boot-webflux

When will it be released ? Or a snapshot version is available

[oliemansm]

Released the starter just now. Can take a bit before it's available from maven central though.

do you know when batch queries is going to be supported on webflux?
