NestJS Integration

TypeGraphQL provides some basic integration with NestJS by the typegraphql-nestjs package.

It allows to use TypeGraphQL features while integrating with NestJS modules system and its dependency injector.

Overview

The usage is similar to the official @nestjs/graphql package. First you need to register your resolver classes in providers of the @Module :

@Module({
  providers: [RecipeResolver, RecipeService],
})
export default class RecipeModule {}

Then you need to register the TypeGraphQL module in your root module - you can pass there all standard buildSchema options:

@Module({
  imports: [
    TypeGraphQLModule.forRoot({
      emitSchemaFile: true,
      authChecker,
      dateScalarMode: "timestamp",
      context: ({ req }) => ({ currentUser: req.user }),
    }),
    RecipeModule,
  ],
})
export default class AppModule {}

And your AppModule is ready to use like with a standard NestJS approach.

Caveats

For now, this basic integration doesn't support other NestJS features like guards, interceptors, filters and pipes. To achieve the same goals, you can use standard TypeGraphQL equivalents - middlewares, custom decorators, built-in authorization and validation.
