graphql-codegen特定のスキーマのタイプスクリプト型ファイルを生成するために使用しています。

エクスポートされたスキームに文字列テンプレートがある場合を除いて、すべて問題ありません。構文に問題があり、コンパイルされないようです。詳細については、次のファイルを確認してください。

を以下types.jsに示します。

const gql = require("graphql-tag");

const Colors = ["Red", "Yellow"];
export default gql`
  type Person {
    name: String
  }
  enum Color {
      ${Colors.join("\n")}
  }
# if we change the above enum to be the below, it will be good
#   enum Color {
#       Red
#       Yellow
#   }
`;

構成 yml ファイルは次のとおりです。

schema: 
  - types.js

generates:
  generated.ts:
    plugins:
        - typescript
        - typescript-resolvers

実行するyarn graphql:codegenと、次のように文句を言います。

Found 1 error

        GraphQL Code Generator supports:
          - ES Modules and CommonJS exports (export as default or named export "schema")
          - Introspection JSON File
          - URL of GraphQL endpoint
          - Multiple files with type definitions (glob expression)
          - String in config file

        Try to use one of above options and run codegen again.

次のようなテンプレート文字列が気に入らgraphql-codegenなかったようです${Colors.join('\n')}

また、上記のすべてのファイルを含むリポジトリについてもご覧ください。

誰でも修正を手伝ってもらえますか?ありがとう。
