We are planning use Graphql as backend server in our application. We choose Graphql-Java to develop our POC. We came across a stituation to create our own scalartype to handle java.util.Map object type.
we havent found any documentation regarding creating a custom scalar type. In example code as below
RuntimeWiring buildRuntimeWiring() {
return RuntimeWiring.newRuntimeWiring()
.scalar(CustomScalar)
how to was the implementation done for CustomScalar object. need help.
To get a general idea how to make a scalar, just take a look into the existing ones and do something similar.
graphql-java also has a separate project for extra scalars: graphql-java-extended-scalars. And there you can find the object scalar (a.k.a. JSON scalar), that can be used for dynamic structures, like Map
s.
Register it via:
RuntimeWiring.newRuntimeWiring().scalar(ExtendedScalars.Object)
