feature: auto-generated update and merge on relationships with properties

[maiieul]

Currently, when creating a relationship with properties using the syntax below, It is only possible to "add" the relationship or to "remove" it through auto-generated mutations. I think it would be nice to be able to MERGE and UPDATE these kinds of relationships with properties through auto-generated queries.

type Rating @relation (name: "RATED") {
  from: User
  to: Category
  value: Int!
}

Can you check the /graphql/experimental endpoint?

That should support it. It’s the new library we’re writing and using for the translation on the jvm

I can try but I don't know how to do that... I am using the neo4j-graphql-js integration. Is it accessible with it?

Or can you tell me or provide a link on how to do that?

Hey there! We should have a refactor of the schema augmentation process for neo4j-graphql-js in soon. It should make the implementation of generated update and merge relationship mutations smoother. The plan is to align with those generated by the neo4j-graphql-java library. I believe there's an issue related to this over in the neo4j-graphql-js repo, if not I'll make one and ping you there when we start to get moving on this :)
