Frequently Asked Questions
Q.Which GraphQL types are converted?
Object types, input types, enums, interfaces, unions, and scalar types are all converted to their TypeScript equivalents.
Q.How are nullable fields handled?
Non-nullable fields (with !) become required properties. Nullable fields use TypeScript union with null or the optional (?) modifier.
Q.Does it support custom scalars?
Common scalars like DateTime and JSON are mapped to appropriate TypeScript types. Unknown scalars default to any.
