How can I generate types that are being used?

[baeharam]

I have schema.graphql and generating types by graphql-code-generator. (I migrated from apollo-codegen) However, this tool is generating all the types in schema.graphql. Apollo-codegen generated types that were being used. Then, how can I generate types that are used only?

You can use onlyOperationTypes: true to get more clear results with typescript-operations. Combing it with preResolveTypes: true should give you a very clean output.
