GraphQL Union and input type?

Question

Is it possible in GraphQL to have an input type that is also a union?

Sort of:

const DynamicInputValueType = new GraphQLUnionType({ name: 'DynamicInputType', types: [GraphQLString, GraphQLFloat, GraphQLInt] }) 

but can also be used as an input for a mutation?

Answer 1

As of September 2017, this is not possible. discussion of this function continues .

Answer 2

There is an npm module. I have not tested. https://www.npmjs.com/package/graphql-union-input-type
