Use generic schema types

GraphQL forces you to define all your input and output types and dealing with all that, especially on the mutating side can be a lot of hassle with little pay-off.

Here we’ll talk about how to accept objects and scalars from the QLive domain in a generic way.

GenericScalar

First, there is GenericScalar which means a scalar value of any type.

type GenericScalar = {
  type: string
  value: any
}

The type contains the name of the actual scalar type and value an object matching that scalar type. Note that the contained value is still validated against its normal validation rules.

The java-side scala is io.github.qlivedev.qlive.api.generic.GenericScalar which is defined as scalar in every QLive domain. So as soon as you use that type in any of your method objects, it will be picked up as scalar.

DomainObject

DomainObject is the same for a complete domain object of your domain.

export type GenericDomainObject = {
  type: "DomainObject"
  value: object
}

The java-side scalar is io.github.qlivedev.qlive.api.generic.DomainObject
