Please i have this issue.
I set up codegen.ts as requested along with ["typescript", "typescript-operations", "typescript-urql"] as plugins
In my graphql folder i have

• user.operations.graphql
• user.schema.graphql
  when i execute pnpm generate, i have duplicate types. what could be the reason?
  Thank you.

Hey, can you please share a full reproduction of the issue that you are facing? Normally types should only be generated once and it might seem that you are applying a plugin twice.

I presently use the graphql introspection query to get the available queries and types and use apollo codegen to generate types based only on the results of that introspection fetch request data. It seems that this type generator relies on using the original .schema files. In my case those are not available--would I still be able to generate types with this product?

@zargold Codegen support getting the schema from all possible sources, including from introspection
You can find all options here

Hi Team, I am having an issue after I install graphiql package.
after I install graphiql package I cannot run yarn codegen anymore. it thorw's a syntax error :
⚠ Generate outputs
❯ Generate to ./src/types/graphql.ts
✔ Load GraphQL schemas
✖ Syntax Error: Expected Name, found "}".
◼ Generate

To test, just 'yarn add graphiql' to your existing project. try running yarn codegen - it will fail.
