Extending a Service with Effect Typescript Library

export class SomeDep extends Effect.Service<SomeDep>()("SomeDep", {
  sync: () => ({
    doSomething: () => console.log("I am doing something"),
  }),
}) {}

export class SharedFooService extends Effect.Service<SharedFooService>()(
  "shared/FooService",
  {
    accessors: true,
    dependencies: [SomeDep.Default],

    effect: Effect.gen(function* () {
      const someDep = yield* SomeDep;

      return {
        foo: someDep.doSomething,
      };
    }),
  },
) {}

export class SpecificFooService extends Effect.Service<SpecificFooService>()(
  "specific/FooService",
  {
    accessors: true,
    dependencies: [SharedFooService.Default],

    effect: Effect.gen(function* () {
      const { _tag, ...sharedFooService } = yield* SharedFooService;

      return {
        ...sharedFooService,
        bar: () => console.log("Doing bar"),
      };
    }),
  },
) {}
