TypeGraphQL
Create GraphQL schema and resolvers with TypeScript
...Use only classes and decorators to define your GraphQL schema. No need to define types in SDL and no need to create interfaces for them! This way you will have only one source of truth, so say goodbye to all field type mismatches, typos, and annoying refactoring. Define your whole schema, including types, interfaces, enums, unions, and subscriptions. Create the schema, types, and resolvers only with TypeScript, using classes and decorators! Use features like automatic validation, authorization guards, dependency injection, and plenty more. ...
