Conditional uses of arguments

[Naoto-Ida]

Is there any support for conditional uses of arguments, i.e. when you have at and by,
but you can only accept an argument one at a time. Or should we write the code ourselves to check if both arguments are available in throw an GraphQLError?

GraphQLObjectType({
    name: 'Event',
    type: new GraphQLList(EventType),
    args: {
        at: {
            type: CoordinateType,
            description: 'Coordinates of the event's venue (approximate).'
        },
        by: {
            type: CoordinateType,
            description: 'Coordinates of the event's venue (exact).'
        },
    }
})

Can't say I speak with authority but I think the answer is no. Your other options are to have two fields names EventAt(CoordinateType) & EventBy(CoordinateType) or an additional boolean argument to field Event(c: CoordinateType, isExact: Boolean)

Can't say I like either of those options either 😄

@IamCornholio Roger that. Your option may be very close to what I need now. Thanks for the advice 😀

Cases like this is why some are arguing for union input types: graphql/graphql-js#207 That proposal has some issues, but this is certainly an area where GraphQL could improve.

Closing this aging issue. Custom code would be necessary to enforce this sort of argument usage.
