Usage Explanation

Schema can be inputted via a file or stdin and formatted as either JSON (Introspection Query result) or GraphQL Schema Language.

If a query.gql file is specified, gql2ts will run the query against the schema and generate interfaces based on that. If no query is specified, gql2ts will create a namespace for your schema and add the interfaces to there.

For -e or --external-options, the input should be either an ES Module with a default export or a CommonJS Module that defines a language package (default: @gql2ts/language-typescript) or overrides for a language. The interface for this file (export default Partial<IFromQueryOption>) can be found in @gql2ts/types.
