GraphQL - Using same field names in different types within union

Question

If I have a union type like this:

union AllOnboardingQuestionTypes = StepFinal | TimeRangesQuestion | PercentQuestion | SingleSelectQuestion | MultiSelectQu         


        

Answer 1

is this the right way to do the query?

Yes. Unions are restricted in this way according to the current (June2018) GraphQL specification. See also a corresponding issue on graphql.js

The aliases seem cumbersome

The best way to avoid this is for the schema to specify different field names when the return types differ.

Answer 2

I had the same problem and find three different solutions to it:

1. Using Interface
2. Using Union
3. Using a String with additional type information

All not very nice but working. I put a simple example project with all solutions on Github: https://github.com/chnoack/apollo-dynamic-types-example
