I have some fields like createdAt
that are typed as the custom DateTime
scalar type (provided by the graphql-iso-date
npm package) in my GraphQL schema.
The problem is that when the Relay compiler generates TypeScript types, the type specified for the DateTime
fields is unknown
.
Since DateTime
fields are just strings representing an ISO date, can we make the Relay compiler specify string
as the type of those fields instead of unknown
?

You can specify the type for any custom scalar type that you might have in your GraphQL schema by providing the following command line argument to the relay-compiler
:
--customScalars.<ScalarName>=<ScalarType>
Where <ScalarName>
is the name of your custom scalar type, e.g., DateTime
, and <ScalarType>
is one of the built-in GraphQL scalar types, e.g., String
or Int
.
So, in your case, you would specify
--customScalars.DateTime=String
If you have more than one scalar type, just specify the --customScalars
argument multiple times.
