 - [`arrayInputCoercion`](/plugins/typescript/typescript-operations#arrayinputcoercion): The [GraphQL spec](https://spec.graphql.org/draft/#sel-FAHjBJFCAACE_Gh7d) allows arrays and a single primitive value for list input. This allows to deactivate that behavior to only accept arrays instead of single values.
 - [`enumsAsTypes`](/plugins/typescript/typescript#enumsastypes): Generates enum as TypeScript string union `type` instead of an `enum`. Useful if you wish to generate `.d.ts` declaration file instead of `.ts`, or if you want to avoid using TypeScript enums due to bundle size concerns.
 - [`enumsAsConst`](/plugins/typescript/typescript#enumsasconst): Generates enum as TypeScript const assertions instead of enum. This can even be used to enable enum-like patterns in plain JavaScript code if you choose not to use TypeScript’s enum construct.
+- [`enumValues`](/plugins/typescript/typescript#enumvalues): Overrides the default value of enum values declared in your GraphQL schema. You can also map the entire enum to an external type by providing a string that of module#type.
 - [`dedupeFragments`](/plugins/typescript/typescript#dedupefragments): Removes fragment duplicates for reducing data transfer. It is done by removing sub-fragments imports from fragment definition.
 - [`nonOptionalTypename`](/plugins/typescript/typescript#nonoptionaltypename): Automatically adds `__typename` field to the generated types, even when they are not specified in the selection set, and makes it non-optional.
 - [`avoidOptionals`](/plugins/typescript/typescript#avoidoptionals): This will cause the generator to avoid using TypeScript optionals (`?`) on types.
